背景

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<V extends Vo, S extends So, PK extends Serializable> {    protected Class<V> voClazz;    @Autowired    private Service<V, S, PK> service;    public AbstractRestController() {      TypeToken<V> voType = new TypeToken<V>(getClass()) {      };      voClazz = (Class<V>) 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<V> list = service.findAll();      PageInfo pageInfo = new PageInfo(list);      excelExportParam();      return ResultGenerator.genSuccessResult(pageInfo);    }    protected void excelExportParam() {      ExportParams ep = new ExportParams(null, "数据");      ExcelExportParam<V> 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<V> vos = service.findByIds(ids);      return ResultGenerator.genSuccessResult(vos);    }    @PostMapping("/batch")    @ApiOperation(value = "批量新建实体", notes = "")    public Result add(@RequestBody List<V> 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);    }
