通过SpringBoot+百度地图+Mysql实现中国地图可视化
一、申请百度地图的ak值
进入百度开发者平台
编辑以下内容
然后申请成功
二、Springboot写一个接口
确保数据库里有数据
文件目录如下
1、配置application.properties文件
#访问端口号
server.port=9090
# 数据库连接信息
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/JobData?serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=1234
# 连接池配置
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.druid.initial-size=20
spring.datasource.druid.min-idle=10
spring.datasource.druid.max-active=100
# 实体类使用驼峰命名。数据库使用下划线
mybatis.configuration.map-underscore-to-camel-case=true2、配置pom.xml文件
<parent><artifactId>spring-boot-test</artifactId><groupId>org.springframework.boot</groupId><version>2.1.3.RELEASE</version></parent><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!--视图依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><!--实体类代码简化依赖--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.22</version></dependency><!--引入数据库的依赖--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.1.1</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.1.10</version></dependency><!--Mybatis--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.2.0</version></dependency><!--mybatis-plus--><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.1.2</version></dependency>
</dependencies>
3、编写com/App.java启动类
package com;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class App {// 调用SpringApplication的run方法来启动Spring Boot应用程序。// 传入的App.class参数指定了应用程序的启动类。public static void main(String[] args) {SpringApplication.run(App.class);}
}
4、编写controller/CityController.java
package com.controller;import com.entity.CityEntity;
import com.service.CityService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.List;@RestController
@RequestMapping("city")
public class CityController {@Autowiredprivate CityService cityService;@RequestMapping("list")public List<CityEntity> list() {return cityService.list();}
}5、编写
5、编写dao/CityDao.java
package com.dao;import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.entity.CityEntity;
import org.apache.ibatis.annotations.Mapper;@Mapper
public interface CityDao extends BaseMapper<CityEntity> {}
6、编写entity/CityEntity.java
封装数据库字段信息
package com.entity;import com.baomidou.mybatisplus.annotation.TableName;
import lombok.*;@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@Data
@TableName("t_city_count") //数据库表名
public class CityEntity {private String city;private int count;
}
7、编写service/CityService.java
package com.service;import com.baomidou.mybatisplus.extension.service.IService;
import com.entity.CityEntity;public interface CityService extends IService<CityEntity> {
}
8、编写service/impl/CityServiceImpl.java
package com.service.impl;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.dao.CityDao;
import com.entity.CityEntity;
import com.service.CityService;
import org.springframework.stereotype.Service;@Service("CityService")
public class CityServiceImpl extends ServiceImpl<CityDao, CityEntity> implements CityService {
}
9、启动App类
结果：
访问端口
http://localhost:9090/city/list得到数据
三、可视化
1、选择Echarts中地图示例
选择Echarts中地图示例，我选择的是这个
2、创建html文件
在resources/templates创建html文件
在html文件中引用 js 文件
通过jQuery获取接口数据，完整代码如下：
<div id="main" style="width:1620px; height:750px;"></div>
<script type="text/javascript">window.onload = function citys() {// 基于准备好的dom，初始化echarts实例var myChart = echarts.init(document.getElementById('main'));myChart.showLoading(); //数据加载完之前先显示一段简单的loading动画//声明一个对象var citylist = [];var nus = [];$.ajax({async: true, //异步请求data: {},//请求方式gettype: "GET",//请求地址url: "/city/list",//数据，json字符串dataType: "json",//请求成功success: function (result) {console.log(result);//进行数据的遍历$.each(result, function (index, item) {citylist.push(item.city);// 格式化对象nus.push({name: item.city,value: item.count});});console.log(citylist);console.log(nus);myChart.hideLoading(); //隐藏加载动画var data = nus; // 城市的数据// 地理坐标var geoCoordMap = {海门: [121.15, 31.89],鄂尔多斯: [109.781327, 39.608266],招远: [120.38, 37.35],舟山: [122.207216, 29.985295],齐齐哈尔: [123.97, 47.33],盐城: [120.13, 33.38],赤峰: [118.87, 42.28],青岛: [120.33, 36.07],乳山: [121.52, 36.89],金昌: [102.188043, 38.520089],泉州: [118.58, 24.93],莱西: [120.53, 36.86],日照: [119.46, 35.42],胶南: [119.97, 35.88],南通: [121.05, 32.08],拉萨: [91.11, 29.97],云浮: [112.02, 22.93],梅州: [116.1, 24.55],文登: [122.05, 37.2],上海: [121.48, 31.22],攀枝花: [101.718637, 26.582347],威海: [122.1, 37.5],承德: [117.93, 40.97],厦门: [118.1, 24.46],汕尾: [115.375279, 22.786211],潮州: [116.63, 23.68],丹东: [124.37, 40.13],太仓: [121.1, 31.45],曲靖: [103.79, 25.51],烟台: [121.39, 37.52],福州: [119.3, 26.08],瓦房店: [121.979603, 39.627114],即墨: [120.45, 36.38],抚顺: [123.97, 41.97],玉溪: [102.52, 24.35],张家口: [114.87, 40.82],阳泉: [113.57, 37.85],莱州: [119.942327, 37.177017],湖州: [120.1, 30.86],汕头: [116.69, 23.39],昆山: [120.95, 31.39],宁波: [121.56, 29.86],湛江: [110.359377, 21.270708],揭阳: [116.35, 23.55],荣成: [122.41, 37.16],连云港: [119.16, 34.59],葫芦岛: [120.836932, 40.711052],常熟: [120.74, 31.64],东莞: [113.75, 23.04],河源: [114.68, 23.73],淮安: [119.15, 33.5],泰州: [119.9, 32.49],南宁: [108.33, 22.84],营口: [122.18, 40.65],惠州: [114.4, 23.09],江阴: [120.26, 31.91],蓬莱: [120.75, 37.8],韶关: [113.62, 24.84],嘉峪关: [98.289152, 39.77313],广州: [113.23, 23.16],延安: [109.47, 36.6],太原: [112.53, 37.87],清远: [113.01, 23.7],中山: [113.38, 22.52],昆明: [102.73, 25.04],寿光: [118.73, 36.86],盘锦: [122.070714, 41.119997],长治: [113.08, 36.18],深圳: [114.07, 22.62],珠海: [113.52, 22.3],宿迁: [118.3, 33.96],咸阳: [108.72, 34.36],铜川: [109.11, 35.09],平度: [119.97, 36.77],佛山: [113.11, 23.05],海口: [110.35, 20.02],江门: [113.06, 22.61],章丘: [117.53, 36.72],肇庆: [112.44, 23.05],大连: [121.62, 38.92],临汾: [111.5, 36.08],吴江: [120.63, 31.16],石嘴山: [106.39, 39.04],沈阳: [123.38, 41.8],苏州: [120.62, 31.32],茂名: [110.88, 21.68],嘉兴: [120.76, 30.77],长春: [125.35, 43.88],胶州: [120.03336, 36.264622],银川: [106.27, 38.47],张家港: [120.555821, 31.875428],三门峡: [111.19, 34.76],锦州: [121.15, 41.13],南昌: [115.89, 28.68],柳州: [109.4, 24.33],三亚: [109.511909, 18.252847],自贡: [104.778442, 29.33903],吉林: [126.57, 43.87],阳江: [111.95, 21.85],泸州: [105.39, 28.91],西宁: [101.74, 36.56],宜宾: [104.56, 29.77],呼和浩特: [111.65, 40.82],成都: [104.06, 30.67],大同: [113.3, 40.12],镇江: [119.44, 32.2],桂林: [110.28, 25.29],张家界: [110.479191, 29.117096],宜兴: [119.82, 31.36],北海: [109.12, 21.49],西安: [108.95, 34.27],金坛: [119.56, 31.74],东营: [118.49, 37.46],牡丹江: [129.58, 44.6],遵义: [106.9, 27.7],绍兴: [120.58, 30.01],扬州: [119.42, 32.39],常州: [119.95, 31.79],潍坊: [119.1, 36.62],重庆: [106.54, 29.59],台州: [121.420757, 28.656386],南京: [118.78, 32.04],滨州: [118.03, 37.36],贵阳: [106.71, 26.57],无锡: [120.29, 31.59],本溪: [123.73, 41.3],克拉玛依: [84.77, 45.59],渭南: [109.5, 34.52],马鞍山: [118.48, 31.56],宝鸡: [107.15, 34.38],焦作: [113.21, 35.24],句容: [119.16, 31.95],北京: [116.46, 39.92],徐州: [117.2, 34.26],衡水: [115.72, 37.72],包头: [110, 40.58],绵阳: [104.73, 31.48],乌鲁木齐: [87.68, 43.77],枣庄: [117.57, 34.86],杭州: [120.19, 30.26],淄博: [118.05, 36.78],鞍山: [122.85, 41.12],溧阳: [119.48, 31.43],库尔勒: [86.06, 41.68],安阳: [114.35, 36.1],开封: [114.35, 34.79],济南: [117, 36.65],德阳: [104.37, 31.13],温州: [120.65, 28.01],九江: [115.97, 29.71],邯郸: [114.47, 36.6],临安: [119.72, 30.23],兰州: [103.73, 36.03],沧州: [116.83, 38.33],临沂: [118.35, 35.05],南充: [106.110698, 30.837793],天津: [117.2, 39.13],富阳: [119.95, 30.07],泰安: [117.13, 36.18],诸暨: [120.23, 29.71],郑州: [113.65, 34.76],哈尔滨: [126.63, 45.75],聊城: [115.97, 36.45],芜湖: [118.38, 31.33],唐山: [118.02, 39.63],平顶山: [113.29, 33.75],邢台: [114.48, 37.05],德州: [116.29, 37.45],济宁: [116.59, 35.38],荆州: [112.239741, 30.335165],宜昌: [111.3, 30.7],义乌: [120.06, 29.32],丽水: [119.92, 28.45],洛阳: [112.44, 34.7],秦皇岛: [119.57, 39.95],株洲: [113.16, 27.83],石家庄: [114.48, 38.03],莱芜: [117.67, 36.19],常德: [111.69, 29.05],保定: [115.48, 38.85],湘潭: [112.91, 27.87],金华: [119.64, 29.12],岳阳: [113.09, 29.37],长沙: [113, 28.21],衢州: [118.88, 28.97],廊坊: [116.7, 39.53],菏泽: [115.480656, 35.23375],合肥: [117.27, 31.86],武汉: [114.31, 30.52],大庆: [125.03, 46.58]};var convertData = function (data) { // 遍历传入的data数组。var res = [];for (var i = 0;
