使用了restful的小伙伴对于导出这些需求本能就是拒绝的~破坏了restful的url的一致性【严格矫正 不是http json就是restful 很多小伙伴都会吧暴露出一个json就直接称为restful 】

正如上文的代码生成器 我们会批量生成一堆代码 其中绝大部分都是RestController

  public abstract class AbstractRestController {
    protected Class voClazz;
    @Autowired
    private Service service;
    public AbstractRestController() {
      TypeToken voType = new TypeToken(getClass()) {
      };
      voClazz = (Class) voType.getRawType();
    }
    @PostMapping()
    @ApiOperation(value = "新建实体", notes = "")
    public Result add(@RequestBody V vo) {
      service.saveSelective(vo);
      return ResultGenerator.genSuccessResult();
    }
    @DeleteMapping("/{id}")
    @ApiOperation(value = "删除实体", notes = "")
    public Result delete(@PathVariable PK id) {
      service.deleteById(id);
      return ResultGenerator.genSuccessResult();
    }
    @PutMapping
    @ApiOperation(value = "更新实体", notes = "")
    public Result update(@RequestBody V vo) {
      service.updateByPrimaryKeySelective(vo);
      return ResultGenerator.genSuccessResult();
    }
    @GetMapping
    @ApiOperation(value = "获取实体列表", notes = "")
    public Result list(S so) {
      PageHelper.startPage(so.getCurrentPage(), so.getPageSize());
      List list = service.findAll();
      PageInfo pageInfo = new PageInfo(list);
      excelExportParam();
      return ResultGenerator.genSuccessResult(pageInfo);
    }
    protected void excelExportParam() {
      ExportParams ep = new ExportParams(null, "数据");
      ExcelExportParam param = new ExcelExportParam<>();
      param.setClazz(voClazz);
      param.setExcelExport(ExcelExport.NormalExcel);
      param.setExportParams(ep);
      param.setFileName("文件.xls");
      F6Static.setExcelExportParam(param);
    }
    @GetMapping("/{id}")
    @ApiOperation(value = "获取单个实体", notes = "")
    public Result detail(@PathVariable PK id) {
      V vo = service.findById(id);
      return ResultGenerator.genSuccessResult(vo);
    }
    @DeleteMapping("/batch")
    @ApiOperation(value = "批量删除实体", notes = "")
    public Result batchDelete(@RequestParam String ids) {
      service.deleteByIds(ids);
      return ResultGenerator.genSuccessResult();
    }
    @GetMapping("/batch")
    @ApiOperation(value = "批量获取实体", notes = "")
    public Result batchDetail(@RequestParam String ids) {
      List vos = service.findByIds(ids);
      return ResultGenerator.genSuccessResult(vos);
    }
    @PostMapping("/batch")
    @ApiOperation(value = "批量新建实体", notes = "")
    public Result add(@RequestBody List vos) {
      service.save(vos);
      return ResultGenerator.genSuccessResult();
    }
    @GetMapping("/count")
    @ApiOperation(value = "获取实体数目", notes = "")
    public Result count(@RequestBody V v) {
      int count = service.selectCount(v);
      return ResultGenerator.genSuccessResult(count);
    }
