阶段三：项目开发---民航功能模块实现：任务24：航空实时监控

任务描述

内容：地图展示、飞机飞行轨迹、扇区控制。航空实时监控，是飞机每秒发送坐标，经过终端转换实时发送给塔台，为了飞机位置的精准度，传输位置的密度很大，在地图位置显示不明显。本次为了案例展示效果，对飞机位置重新进行了规划，结合百度地图，和数据清洗，展示到前台。

学时：6学时

知识点：后端文件处理

重点：百度地图展示、飞机动态飞行、数据获取

任务指导

1、后台从文件名为part-xxxxx的文件中读取每行飞机坐标点传输到Kafka，Spark清洗任务拉取Kafka数据对数据进行清洗，对数据坐标进行判断转换成各扇区，发送到MySQL作为转换后的数据点，这一过程在前面的数据清洗和统计任务阶段已经完成，可参见：

BigData-Etl-KongGuan/src/main/java/com/qrsoft/etl/spark/SparkUtil.java类
BigData-Etl-KongGuan/src/main/java/com/qrsoft/etl/spark/SparkStreamingApplication.java类

2、前端经过读取后台MySQL的数据并结合百度地图，将飞机的实时飞行状态展示出来，可按以下步骤实现：

1）引入百度地图

2）地图上添加飞机

3）飞机动态修改

4）Vue中重新绑定值

3、后台逻辑实现（BigData-KongGuan）

1）编写后台逻辑，访问数据库，查询飞行实时数据

4、完成功能测试

下面图中是原企业项目的真实展示页面，在当前项目中由于数据集的特点，实际展示效果可能会有差异。

任务实现

1、从Kafka中读取飞机数据，并进行清洗

此步骤在前面的“使用Spark清洗统计业务数据并保存到数据库中”任务阶段应该已经完成。如果没有完成，请参考源代码自行完成。核心类主要有三个：SparkStreamingApplication类、SparkUtil类和MapManager类，以及一些辅助类。

BigData-Etl-KongGuan/src/main/java/com/qrsoft/etl/spark/SparkStreamingApplication.java类的作用是实时读取Kafka中所有Topic的数据，然后进入到不同的处理分支程序中进行数据清洗和存储，处理“实时飞行的航迹数据”的分支的代码如下：

SparkUtil sparkUtil = new SparkUtil();
try {switch (topName) {case Constants.TASK_RADAR:sparkUtil.TaskRadarStr(taskRadar);break;

进入 Constants.TASK_RADAR 分支后，会调用SparkUtil类中的TaskRadarStr方法来处理数据，BigData-Etl-KongGuan/src/main/java/com/qrsoft/etl/spark/SparkUtil.java类中相关的核心代码如下：

    /*** 业务处理* @param strs    航迹数据*/public void TaskRadarStr(String strs){System.out.println(strs);String[] str = strs.split(",");logger.info(str.toString());try {//判断是哪个扇区 sectionG sectionK sectionEString sectionVal = "";MapManager mapMan = new MapManager();double lat = Double.valueOf(str[8]);double lng = Double.valueOf(str[9]);if(mapMan.isInRectangleArea(lat,lng,sectionG[0],sectionG[1],sectionG[2],sectionG[3])){sectionVal = "G";}else if(mapMan.isInRectangleArea(lat,lng,sectionK[0],sectionK[1],sectionK[2],sectionK[3])){sectionVal = "K";}else if(mapMan.isInRectangleArea(lat,lng,sectionE[0],sectionE[1],sectionE[2],sectionE[3])){sectionVal = "E";};System.out.println("=========================================================");System.out.println("========================"+sectionVal+"=================================");System.out.println("=========================================================");MultiRadar mr = new MultiRadar();//MultiRadar mr = new MultiRadar(str[1],str[12],str[11],str[0],str[17],str[15],str[18],str[19],str[9],str[8],str[7],str[13],str[14],str[10],str[3],str[6],str[4],str[16],str[5],str[2],sectionVal);mr.setAcid(str[0]);mr.setAreaSource(str[1]);mr.setClimbordownSpeed(str[2]);mr.setDirection(str[3]);mr.setFcu(str[4]);mr.setFlyStatus(str[5]);mr.setRadarCFL(str[6]);mr.setRadarHeight(str[7]);mr.setRadarLatitude(str[8]);mr.setRadarLongTitude(str[9]);mr.setRadarSpeed(str[10]);mr.setRadarType(str[11]);mr.setSendRadarTime(str[12]);mr.setSpeedX(str[13]);mr.setSpeedY(str[14]);mr.setSsrCode(str[15]);mr.setTime(str[16]);mr.setTrackNumber(str[17]);mr.setZhiJiaoX(str[18]);mr.setZhiJiaoY(str[19]);mr.setSection(sectionVal);//根据航班号，查询是否已经开始对该航迹进行统计MultiRadarDao dao = new MultiRadarDao();boolean bool = dao.isExistThisRadar(mr.getAcid());if(bool) {//存在，修改数据库中该航迹dao.updateAnRadarMsg(mr);}else{//尚未进行统计 创建一个统计信息dao.createAnRadarMsg(mr);}}catch (Exception e){e.printStackTrace();logger.info(" MultiRadar错误数据： [{}]", strs);}}

在处理“实时飞行的航迹数据”时，会使用到一个辅助类MapManager，该类的功能包括：判断飞机是否在指定的矩形区域内、判断飞机是否在指定的经纬度范围内，核心代码如下：

public class MapManager {/*** 是否在矩形区域内* * @param lat 测试点经度* @param lng 测试点纬度* @param minLat 纬度范围限制1* @param maxLat 纬度范围限制2* @param minLng 经度限制范围1* @param maxLng 经度范围限制2*/public  boolean isInRectangleArea(double lat,double lng,double minLat, double maxLat,double minLng,double maxLng){if(this.isInRange(lat, minLat, maxLat)){//如果在纬度的范围内if(minLng*maxLng>0){if(this.isInRange(lng, minLng, maxLng)){return true;}else {return false;}}else {if(Math.abs(minLng)+Math.abs(maxLng)<180){if(this.isInRange(lng, minLng, maxLng)){return true;}else {return false;}}else{double left = Math.max(minLng, maxLng);double right = Math.min(minLng, maxLng);if(this.isInRange(lng, left, 180)||this.isInRange(lng, right,-180)){return true;}else {return false;}}}}else{return false;}}/*** 判断是否在经纬度范围内* * @param point* @param left* @param right*/public  boolean isInRange(double point, double left,double right){if(point>=Math.min(left, right)&&point<=Math.max(left, right)){return true;}else {return false;}}
}

其他辅助类，请参考源代码。

2、打开前端Vue项目kongguan_web，完成前端Vue页面（src/views/Home/Map.vue）设计

在Vue页面 src/views/Home/Map.vue 中引入百度地图，首先添加百度地图背景图，并在地图上飞机，飞机相当于在地图上添加mark点

其中bm-marker是飞机，bm-label是飞机旁边显示的标签，通过v-for标签循环绑定数据，例如：v-for="item in caseList"，caseList是在下边的数据获取步骤中赋值的。

<template><div style="height: 100%"><baidu-map :center="center" :zoom="zoom"  style="height:100%" @click="getClickInfo":scroll-wheel-zoom='true' :map-style="mapStyle"><bm-marker v-for="item in caseList" :key="item.id":position="{lng: item.radarLongtitude, lat: item.radarLatitude}" :rotation="Number(item.direction)":icon="{url: urlz(item.id), size: {width: 100, height: 75}}"><bm-label  :position="{lng: item.radarLongtitude, lat: item.radarLatitude}":content="item.acid":labelStyle="{color: 'gray', fontSize : '8px',backgroundColor: 'rgba(0,0,0,0)',border:0}"title="Hover me"/></bm-marker><!-- 缩放控件，注册此组件才会显示拖放进度 --><bm-navigation anchor="BMAP_ANCHOR_TOP_LEFT"></bm-navigation></baidu-map>
... 接下文 ...

在Vue页面中添加扇区管理的页面设计：

页面中包含"G"、"K"、"E"三个扇区的按钮，并绑定了click事件，当点击其中任意一个扇区对应的按钮时会触发click事件，执行clickData方法，clickData方法在后面的步骤中定义，主要是根据传入的不同的参数（"G"、"K"、"E"），获取不同扇区的数据。

... 接上文 ...<div class="allStatistics box"><img src="../../assets/images/nl.png" width="45px" height="45px" style="position: absolute;right: 90px;top: 75px"><img src="../../assets/images/gj.png" width="45px" height="45px"style="position: absolute ;right: 290px;top: 70px"><div style=" margin-left: 70px;margin-top: 12px"><div>当前时间：{{new Date().getFullYear()}}-{{new Date().getMonth()}}-{{new Date().getDate()}} &ensp;{{newDate().getHours()}}:{{new Date().getMinutes()}}:{{new Date().getSeconds()}}</div><div style="margin-left: -17px">当前位置：{{this.center.lng}} {{this.center.lat}}</div></div><div style=" font-weight: bold;position: absolute;top: 145px;left: 45px"><span style="color: #2a58f4">轨迹数：</span><span style="color: #2a58f4">{{count}}</span><span style="color: #f17140;margin-left: 52px">告警数：</span><span style="color: #f17140">{{count1}}</span></div></div><div class="sectors1 box"><div class="title">当前用户: <span class="npc">管理员 G</span></div><div ><el-button :type="isActive==='G'?'success':'primary'" style="margin-left: 16px" @click="clickData('G')">G</el-button><el-button :type="isActive==='K'?'success':'primary'" :class="isActive === 2?'active':''"@click="clickData('K')">k</el-button><el-button :type="isActive==='E'?'success':'primary'" :class="isActive === 3?'active':''"@click="clickData('E')">E</el-button></div></div><div class="sectors2 box"><div class="title">扇区状态栏</div><div><el-button :type="isActive==='G'?'success':'primary'" style="margin-left: 16px" @click="clickData('G')">G</el-button><el-button :type="isActive==='K'?'success':'primary'" :class="isActive === 2?'active':''"@click="clickData('K')">k</el-button><el-button :type="isActive==='E'?'success':'primary'" :class="isActive === 3?'active':''"@click="clickData('E')">E</el-button></div></div><div class="simi_box box"><div class="similarity"><el-tag effect="dark"><span class="tag-group__title" style="">相似航班数提醒</span></el-tag><div v-for="(it,index) in atcList" :key="index" style="height: 45px; font-weight: bold;"><spanstyle="margin-left: 25px">{{it.gjSector}}</span><spanstyle="margin-left: 45px">{{it.gj}}</span></div></div><div class="similarity"><el-tag effect="dark"><span class="tag-group__title" style="">管制指令纠错</span></el-tag><div v-for="(it,index) in warnList" :key="index"><div style="height: 45px;text-align: center"><spanstyle="width: 100%; font-weight: bold;">{{it.gj_acids}}</span></div><div style="height: 45px;text-align: center;"><table style="height: 45px"><tr><td style="width: 150px; border: #2a58f4 3px solid; border-left: none">{{it.gj_name}}</td><td style="width: 83px; border: #2a58f4 3px solid">{{it.gj_track_num1}}</td><td style="width: 83px; border: #2a58f4 3px solid">{{it.gj_track_num2}}</td><td style="width: 83px; border: #2a58f4 3px solid; border-right: none">{{it.gj_distinct}}</td></tr></table></div></div></div></div></div>

获取数据

其中loadData方法是用来获取实时飞行数据，loadWarn方法是获取告警信息，clickData方法是响应扇区按钮的点击事件，查询不同扇区对应的数据。

... 接上文 ...mounted() {this.loadWarn();this.loadData();this.clickData();this.timeOut();},beforeDestroy() {    //页面关闭时清除定时器  window.clearInterval(this.timer);this.timer = null;},destroyed() {window.clearInterval(this.timer);this.timer = null; },methods: {urlz(data){for(let i=0;i<this.warnList.length;i++){var value1 = this.warnList[i].gj_track_num1;var value2 = this.warnList[i].gj_track_num2;if(value1 == data || value2 == data){return  this.url2;}}return this.url1;},getClickInfo(e) {this.center.lng = e.point.lngthis.center.lat = e.point.lat},loadData() {findMultRadar().then(data => {if (data.isSuccess) {this.caseList = data.result;this.caseList.forEach(it => {it.count = it.areaSource + "," + it.trackNumber})} else {this.$message.error("数据获取失败");}})},loadWarn(){findWarnTp().then(data => {if (data.isSuccess) {this.warnList = data.result;} else {this.warnList.error("数据获取失败");}})},clickData(data) {if (data == null) {this.isActive = 'G'data = 'G'} else {this.isActive = data}findLocusCount(data).then(data => {if (data.isSuccess) {this.count = data.result;} else {this.warnList.error("数据获取失败");}}),findWarnSimilarOfATC(data).then(data => {if (data.isSuccess) {this.atcList = data.result;} else {this.atcList.error("数据获取失败");}}),findWarnSimilarOfATCCount(data).then(data => {if (data.isSuccess) {this.count1 = data.result;} else {this.count1.error("数据获取失败");}})},

</style>

在src/api/目录下创建map目录，然后创建api路由文件 src/api/map/map.js，用于访问服务端相应的Controller（主要是通过findMultRadar()方法“查询综合航迹数据”并显示航迹图，还会涉及到“管制指令纠错”、“根据扇区名称获取该扇区航班数”、“根据扇区号查询相似航班”、“根据扇区号查询相似航班告警总数”等数据的展示）

import request from "../../utils/request";//综合航迹数据查询相关的服务器端请求的根路径
const baseUrl="/api/multiRadar"
//年度统计查询相关的服务器端请求的根路径
const warUrl ="/api/warnFlightHistory"
//航班告警查询相关的服务器端请求的根路径
const warSimUrl = "/api/warnSimilarHistory"
//扇区操作查询相关的服务器端请求的根路径
const atcUrl = "/api/atc"//查询综合航迹数据
export function findMultRadar(){return request({url:baseUrl+"/findMultRadar",method: "get",})
}
//管制指令纠错
export function findWarnTp(){return request({url:warUrl+"/findWarnTp",method: "get",})
}
//根据扇区名称获取该扇区航班数
export function findLocusCount(data){return request({url:atcUrl+"/findLocusCount?planSectorName="+data,method: "get",})
}
//根据扇区号查询相似航班
export function findWarnSimilarOfATC(data){return request({url:warSimUrl+"/findWarnSimilarOfATC?sectorName="+data,method: "get",})
}
//根据扇区号查询相似航班告警总数
export function findWarnSimilarOfATCCount(data){return request({url:warSimUrl+"/findWarnSimilarOfATCCount?sectorName="+data,method: "get",})
}

修改 src/router/index.js 路由文件，添加Map.vue页面的路由跳转

... 略 ...{path: '/',component: Layout,redirect: '/map',children: [{path: 'map',component: resolve => require(['@/views/Home/Map'], resolve),name: 'map',meta: { title: 'map' }}]},
... 略 ...

src/router/index.js文件的完整内容如下：

import Vue from 'vue'
import Router from 'vue-router'const originalPush = Router.prototype.push;
Router.prototype.push = function push(location) {return originalPush.call(this, location).catch(err => err)
}Vue.use(Router)
/* Layout */
import Layout from '@/views/Layout/Layout'
const router =  new Router({base: process.env.BASE_URL,mode: 'history',routes: [{path: "/login",component: resolve => require(['@/views/Login/Login'], resolve),hidden: true,meta: {auth: true}},{path: '/',component: Layout,redirect: '/home',children: [{path: 'home',component: resolve => require(['@/views/Home/Index'], resolve),name: 'home',meta: { title: 'home' }}]},{path: '/',component: Layout,redirect: '/map',children: [{path: 'map',component: resolve => require(['@/views/Home/Map'], resolve),name: 'map',meta: { title: 'map' }}]},]
})// 导航守卫
// 使用 router.beforeEach 注册一个全局前置守卫，判断用户是否登陆
router.beforeEach((to, from, next) => {if (to.path === '/login') {next();} else {let token = localStorage.getItem('Authorization');if (token === null || token === '') {next('/login');} else {next();}}
});
export default router

确保 src/App.vue 文件的内容如下：

<template><div id="app"><router-view/></div>
</template><script>
export default {name: 'App',
}
</script><style>
html,body,#app{height: 100%;
}
</style>

3、打开后端项目BigData-KongGuan，完成后台逻辑实现

编写以下Controller类，来处理客户端发送过来的请求，涉及以下几个类：

类/接口	作用
com.qrsoft.controller.AtcController	扇区操作类：处理客户端的 /api/atc 相关的扇区操作请求
com.qrsoft.controller.MultiRadarController	综合航迹数据：处理客户端的 /api/multiRadar 相关的综合航迹数据查询请求
com.qrsoft.controller.WarnFlightHistoryController	年度告警统计：处理客户端的 /api/warnFlightHistory 相关的年度统计查询请求
com.qrsoft.controller.WarnSimilarHistoryController	航班告警：处理客户端的 /api/warnSimilarHistory 相关的航班告警查询请求

1）在com.qrsoft.controller.AtcController类中主要调用其中的 findLocusCount() 方法，用于根据扇区名称获取该扇区航班数。

/**
* 根据扇区名称获取该扇区航班数
*/
@ApiOperation(value = "根据扇区名称获取该扇区航班数")
@GetMapping("/findLocusCount")
public Result findLocusCount(@RequestParam String planSectorName){return service.findLocusCount(planSectorName);
}

AtcController类的完整内容如下：

@Api(tags = "扇区操作类")
@RestController
@RequestMapping("/api/atc")
public class AtcController {@Autowiredprivate AtcService service;/*** 获取各扇区航班数*/@ApiOperation(value = "获取各扇区航班数")@GetMapping("/findSectorSortie")public Result findSectorSortie(){return service.findSectorSortie();}/*** 根据扇区名称获取该扇区航班数*/@ApiOperation(value = "根据扇区名称获取该扇区航班数")@GetMapping("/findLocusCount")public Result findLocusCount(@RequestParam String planSectorName){return service.findLocusCount(planSectorName);}/*** 扇区架次数动态统计(饼状图)*/@ApiOperation(value = "扇区架次数动态统计(饼状图)")@GetMapping("/findATCTime")public Result findATCTime(){return service.findATCTime();}
}

2）在com.qrsoft.controller.MultiRadarController类中主要调用findMultRadar()方法，用于综合航迹数据查询，MultiRadarController类的内容如下：

@Api(tags = "综合航迹数据")
@RestController
@RequestMapping("/api/multiRadar")
public class MultiRadarController {@Autowiredprivate MultiRadarService service;/*** 查询综合航迹数据*/@GetMapping("/findMultRadar")public Result findMultRadar(){return service.findMultRadar();}
}

3）在com.qrsoft.controller.WarnFlightHistoryController类中主要调用 findWarnTp() 方法，用于查询“管制指令纠错”的数据。

 /*** 管制指令纠错*/
@ApiOperation(value = "管制指令纠错")
@GetMapping("/findWarnTp")
public Result findWarnTp(){return service.findWarnTp();
}

WarnFlightHistoryController类的完整内容如下：

@Api(tags = "年度统计")
@RestController
@RequestMapping("/api/warnFlightHistory")
public class WarnFlightHistoryController {@Autowiredprivate WarnFlightHistoryService service;/*** 年度警告分类统计*/@ApiOperation(value = "年度警告分类统计")@GetMapping("/annualWarningStatisticsByCategory")public Result annualWarningStatisticsByCategory(){return service.annualWarningStatisticsByCategory();}/*** 年度警告区域统计*/@ApiOperation(value = "年度警告区域统计")@GetMapping("/annualWarningAreaStatistics")public Result annualWarningAreaStatistics(){return service.annualWarningAreaStatistics();}/*** 管制指令纠错*/@ApiOperation(value = "管制指令纠错")@GetMapping("/findWarnTp")public Result findWarnTp(){return service.findWarnTp();}
}

4）创建com.qrsoft.controller.WarnSimilarHistoryController类，在类中主要调用findWarnSimilarOfATC()和findWarnSimilarOfATCCount()方法，用于“根据扇区号查询相似航班告警”和“根据扇区号查询相似航班告警总数”。

/**
* 根据扇区号查询相似航班告警
*/
@ApiOperation(value = "根据扇区号查询相似航班")
@GetMapping("/findWarnSimilarOfATC")
public Result findWarnSimilarOfATC(@RequestParam String sectorName){return service.findWarnSimilarOfATC(sectorName);
}
/**
* 根据扇区号查询相似航班告警总数
*/
@ApiOperation(value = "根据扇区号查询相似航班告警总数")
@GetMapping("/findWarnSimilarOfATCCount")
public Result findWarnSimilarOfATCCount(@RequestParam String sectorName){return service.findWarnSimilarOfATCCount(sectorName);
}

WarnSimilarHistoryController类的完整代码如下：

package com.qrsoft.controller;import com.qrsoft.common.Result;
import com.qrsoft.service.WarnSimilarHistoryService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;@Api(tags = "航班告警")
@RestController
@RequestMapping("/api/warnSimilarHistory")
public class WarnSimilarHistoryController {@Autowiredprivate WarnSimilarHistoryService service;/*** 查询相似航班告警*/@ApiOperation(value = "查询相似航班告警")@GetMapping("/findWarnSimilarHistory")public Result findWarnSimilarHistory(){return service.findWarnSimilarHistory();}/*** 根据扇区号查询相似航班告警*/@ApiOperation(value = "根据扇区号查询相似航班")@GetMapping("/findWarnSimilarOfATC")public Result findWarnSimilarOfATC(@RequestParam String sectorName){return service.findWarnSimilarOfATC(sectorName);}/*** 根据扇区号查询相似航班告警总数*/@ApiOperation(value = "根据扇区号查询相似航班告警总数")@GetMapping("/findWarnSimilarOfATCCount")public Result findWarnSimilarOfATCCount(@RequestParam String sectorName){return service.findWarnSimilarOfATCCount(sectorName);}
}

}

2）创建com.qrsoft.service.MultiRadarService类，类中包含一个findMultRadar()方法，用于查询综合航迹数据，内容如下：

package com.qrsoft.service;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.qrsoft.common.Result;

}

编写对应的Mapper数据访问类，包括以下几个类：

类/接口	作用
com.qrsoft.mapper.AtcMapper	扇区操作的数据访问类
com.qrsoft.mapper.MultiRadarMapper	综合航迹数据查询的数据访问类
com.qrsoft.mapper.WarnFlightHistoryMapper	年度告警数据查询的数据访问类
com.qrsoft.mapper.WarnSimilarHistoryMapper	航班告警数据查询的数据访问类

1）com.qrsoft.mapper.AtcMapper类的内容如下：

@Mapper
public interface AtcMapper extends BaseMapper<Atc> {@Select("select PLAN_SECTOR_NAME,COUNT(*) as count from atc_number GROUP BY PLAN_SECTOR_NAME;")List<Atc> findSectorSortie();@Select("select EXECUTE_DATE from atc_number group by EXECUTE_DATE order by EXECUTE_DATE desc limit 19;")List<String> findATCTime();@Select("select PLAN_SECTOR_NAME,count(*) as count from atc_number where EXECUTE_DATE = #{executeTime} and PLAN_SECTOR_NAME = #{sectorName}")Atc findATCTime2(String executeTime,String sectorName);
}

2）com.qrsoft.mapper.MultiRadarMapper类的内容如下：

@Mapper
public interface MultiRadarMapper extends BaseMapper<MultiRadar> {}

3）com.qrsoft.mapper.WarnFlightHistoryMapper类的内容如下：

@Mapper
public interface WarnFlightHistoryMapper extends BaseMapper<WarnFlightHistory> {@Select("SELECT gj_sector,COUNT(*) as gjCount FROM warnflighthistory_number GROUP BY gj_sector ORDER BY sum(count) desc LIMIT 11;")List<WarnFlightHistory> annualWarningAreaStatistics();@Select("select gj_name,count(*) as gjCount from warnflighthistory_number group by gj_name;")List<WarnFlightHistory> annualWarningStatisticsByCategory();@Select("select gj_type,gj_id,gj_msg_type,gj_track_num1,gj_track_num2,gj_distinct,gj_radian,gj_name,gj_distinct_bz,gj_city,gj_date,gj_acids,gj_num1_long,gj_num1_lat,gj_num2_long,gj_num2_lat from warntp_number;")List<HashMap<String,Object>> findWarnTp();@Select("select count(*) from multiradar_number where `ACID` IN (#{acid},#{bcid});")Integer getWarn(@Param("acid") String acid, @Param("bcid") String bcid);
}

4）创建com.qrsoft.mapper.WarnSimilarHistoryMapper类，内容如下：

package com.qrsoft.mapper;import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.qrsoft.entity.WarnSimilarHistory;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;import java.util.List;@Mapper
public interface WarnSimilarHistoryMapper extends BaseMapper<WarnSimilarHistory> {@Select("SELECT gj_sector,gj_acid FROM warnsimilarhistory_number ORDER BY id DESC LIMIT 4;")List<WarnSimilarHistory> findWarnSimilarHistory();@Select("SELECT gj_sector,gj_acid FROM warnsimilarhistory_number where gj_sector = #{sectorName} ORDER BY id DESC LIMIT 4;")List<WarnSimilarHistory> findWarnSimilarOfATC(@Param("sectorName") String sectorName);
}

涉及的数据实体类包括（在前面的任务中已经创建过，此处只需确认一下是否存在）：

类/接口	作用
com.qrsoft.entity.Atc	扇区对应的实体类
com.qrsoft.entity.MultiRadar	雷达对应的实体类
com.qrsoft.entity.WarnFlightHistory	年度告警飞行历史记录对应的实体类
com.qrsoft.entity.WarnSimilarHistory	航班告警历史记录对应的实体类
com.qrsoft.entity.Company	航空公司信息表对应的实体类
com.qrsoft.common.Result	返回结果类
com.qrsoft.common.ResultConstants	返回常量结果类

1）需要创建com.qrsoft.entity.WarnSimilarHistory类，用于航班告警历史记录对应的实体类，内容如下：

package com.qrsoft.entity;import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;@Data
@AllArgsConstructor
@NoArgsConstructor
@TableName("warnsimilarhistory_number")
public class WarnSimilarHistory implements Serializable {private Integer id;@TableField(value = "gj_type")private String gjType;@TableField(value = "gj_id")private String gjDd;@TableField(value = "gj_msg_type")private String gjMsgType;@TableField(value = "gj_num")private String gjNum;@TableField(value = "gj_track_num")private String gjTrackNum;@TableField(value = "gj_sector")private String gjSector;@TableField(value = "gj_acid")private String gjAcid;@TableField(value = "gj_status")private String gjStatus;@TableField(value = "gj_city")private String gjCity;@TableField(value = "gj_date")private String gjDate;@TableField(value = "count")private Integer count;}

2）其他实体类在前面的任务中已经创建，这里不需要重复创建。
