springboot企业级抽奖项目业务三（活动模块）

梅开三度

开发流程

该业务基于rouyi生成好了mapper和service的代码，现在需要在controller层写接口

实际操作流程：

看接口文档一>controller里定义函数一>看给出的工具类一>补全controller里的函数一>运行测试

接口文档

在用户模块用户先看到活动列表，在活动列表内点击具体活动，进入看到活动信息、奖品信息和中奖列表。

controller里定义

在注解框架里加上list、info、products和hit四个函数

@RestController
@RequestMapping(value = "/api/game")
@Api(tags = {"活动模块"})
public class GameController {@Autowiredprivate GameLoadService loadService;@Autowiredprivate CardGameService gameService;@Autowiredprivate ViewCardUserHitService hitService;@GetMapping("/list/{status}/{curpage}/{limit}")@ApiOperation(value = "活动列表")@ApiImplicitParams({@ApiImplicitParam(name="status",value = "活动状态（-1=全部，0=未开始，1=进行中，2=已结束）",example = "-1",required = true),@ApiImplicitParam(name = "curpage",value = "第几页",defaultValue = "1",dataType = "int", example = "1",required = true),@ApiImplicitParam(name = "limit",value = "每页条数",defaultValue = "10",dataType = "int",example = "3",required = true)})public ApiResult list(@PathVariable int status,@PathVariable int curpage,@PathVariable int limit) {//TODOreturn null;}@GetMapping("/info/{gameid}")@ApiOperation(value = "活动信息")@ApiImplicitParams({@ApiImplicitParam(name="gameid",value = "活动id",example = "1",required = true)})public ApiResult<CardGame> info(@PathVariable int gameid) {//TODOreturn null;}@GetMapping("/products/{gameid}")@ApiOperation(value = "奖品信息")@ApiImplicitParams({@ApiImplicitParam(name="gameid",value = "活动id",example = "1",required = true)})public ApiResult<List<CardProductDto>> products(@PathVariable int gameid) {//TODOreturn null;}@GetMapping("/hit/{gameid}/{curpage}/{limit}")@ApiOperation(value = "中奖列表")@ApiImplicitParams({@ApiImplicitParam(name="gameid",value = "活动id",dataType = "int",example = "1",required = true),@ApiImplicitParam(name = "curpage",value = "第几页",defaultValue = "1",dataType = "int", example = "1",required = true),@ApiImplicitParam(name = "limit",value = "每页条数",defaultValue = "10",dataType = "int",example = "3",required = true)})public ApiResult<PageBean<ViewCardUserHit>> hit(@PathVariable int gameid,@PathVariable int curpage,@PathVariable int limit) {//TODOreturn null;}}

看给出的工具类

找该模块附近的common和util包

补全controller里的函数

比较简单，直接上完整代码（初版，后期修bug）

基本就用wrapper查下

@RestController
@RequestMapping(value = "/api/game")
@Api(tags = {"活动模块"})
public class GameController {@Autowiredprivate GameLoadService loadService;@Autowiredprivate CardGameService gameService;@Autowiredprivate ViewCardUserHitService hitService;@GetMapping("/list/{status}/{curpage}/{limit}")@ApiOperation(value = "活动列表")@ApiImplicitParams({@ApiImplicitParam(name="status",value = "活动状态（-1=全部，0=未开始，1=进行中，2=已结束）",example = "-1",required = true),@ApiImplicitParam(name = "curpage",value = "第几页",defaultValue = "1",dataType = "int", example = "1",required = true),@ApiImplicitParam(name = "limit",value = "每页条数",defaultValue = "10",dataType = "int",example = "3",required = true)})public ApiResult list(@PathVariable int status,@PathVariable int curpage,@PathVariable int limit) {QueryWrapper<CardGame> wrapper = new QueryWrapper<>();if (status != -1) {wrapper.eq("status",status);}Page<CardGame> all = gameService.page(new Page(curpage,limit),wrapper);return new ApiResult(1,"成功",new PageBean<CardGame>(all));}@GetMapping("/info/{gameid}")@ApiOperation(value = "活动信息")@ApiImplicitParams({@ApiImplicitParam(name="gameid",value = "活动id",example = "1",required = true)})public ApiResult<CardGame> info(@PathVariable int gameid) {CardGame game = gameService.getById(gameid);return new ApiResult(1,"成功",game);}@GetMapping("/products/{gameid}")@ApiOperation(value = "奖品信息")@ApiImplicitParams({@ApiImplicitParam(name="gameid",value = "活动id",example = "1",required = true)})public ApiResult<List<CardProductDto>> products(@PathVariable int gameid) {List<CardProductDto> productList = loadService.getByGameId(gameid);return new ApiResult(1,"成功",productList);}@GetMapping("/hit/{gameid}/{curpage}/{limit}")@ApiOperation(value = "中奖列表")@ApiImplicitParams({@ApiImplicitParam(name="gameid",value = "活动id",dataType = "int",example = "1",required = true),@ApiImplicitParam(name = "curpage",value = "第几页",defaultValue = "1",dataType = "int", example = "1",required = true),@ApiImplicitParam(name = "limit",value = "每页条数",defaultValue = "10",dataType = "int",example = "3",required = true)})public ApiResult<PageBean<ViewCardUserHit>> hit(@PathVariable int gameid,@PathVariable int curpage,@PathVariable int limit) {QueryWrapper<ViewCardUserHit> wrapper = new QueryWrapper<>();if (gameid == -1) {wrapper.eq("gameid",gameid);}Page<ViewCardUserHit> all = hitService.page(new Page(curpage,limit),wrapper);return new ApiResult(1,"成功",new PageBean<ViewCardUserHit>(all));}}
