技術標籤：web專案開發

1、定義接收引數DTO，程式碼如下：

@Data
@ApiModel(value = "DataSettingDTO",description = "欄位配置屬性資訊")
public class DataSettingDTO extends BaseDTO implements Serializable {

    private static final long serialVersionUID=1L;

   @ApiModelProperty(value="業務主鍵ID")
   private Integer id;

    /**
     * 欄位型別
     */
    @ApiModelProperty(value="欄位型別")
    private String type;

    /**
     * 欄位值
     */
    @Size(min = 1,max = 20,message = "欄位值長度範圍必須在1~40")
    @ApiModelProperty(value="欄位值")
    private String name;

    /**
     * 欄位描述
     */
     @Size(max = 200,message = "欄位描述長度範圍必須在1~200")
     @ApiModelProperty(value="段描述")
     private String remark;

    /**
     * 建立人
     */
       @ApiModelProperty(value="建立人ID")
       private Integer creator;

    /**
     * 是否刪除0:是，1:否
     */
    @ApiModelProperty(value="是否刪除0:是，1:否")
    private Integer isDelete;

    @Override
    public String toString() {
        return "DataSettingDTO{" +
                "id=" + id +
                ", type='" + type + '\'' +
                ", name='" + name + '\'' +
                ", remark='" + remark + '\'' +
                ", creator=" + creator +
                ", isDelete=" + isDelete +
                '}';
    }
}
 

2、引數入口進行校驗

@Controller
@RequestMapping("/xxx/dataSetting")
@Api(tags = "配置功能_欄位")
public class DataSettingController {

    @Autowired
    private DataSettingBusiness dataSettingBusiness;


    @RequestMapping(method =RequestMethod.GET,value = "select")
    @ResponseBody
    @ApiOperation(value = "欄位詳情",notes = "")
    public Response<?> selectDataSettingById(@ModelAttribute DataSettingDTO dataSettingDTO){
        return dataSettingBusiness.selectDataSettingById(dataSettingDTO);

    }

    @RequestMapping(method =RequestMethod.POST,value = "save")
    @ResponseBody
    @ApiOperation(value = "儲存欄位資訊",notes = "")
    public Response<?>  saveDataSettingById(@Valid @ModelAttribute DataSettingDTO dataSettingDTO){
        return dataSettingBusiness.saveDataSetting(dataSettingDTO);
    }

    @RequestMapping(method =RequestMethod.GET,value = "delete")
    @ResponseBody
    @ApiOperation(value = "刪除欄位資訊",notes = "")
    public Response<?>  deleteDataSettingById(@ModelAttribute DataSettingDTO dataSettingDTO){
        dataSettingBusiness.deleteDataSetting(dataSettingDTO);
        return ResponseUtils.returnSuccess();
    }

    @RequestMapping(method =RequestMethod.POST,value = "update")
    @ResponseBody
    @ApiOperation(value = "修改編輯欄位資訊",notes = "")

    public Response<?>  updateDataSettingById(@Valid @ModelAttribute DataSettingDTO dataSettingDTO){
        return dataSettingBusiness.updateDataSetting(dataSettingDTO);
    }

    @RequestMapping(method =RequestMethod.GET,value = "list")
    @ResponseBody
    @ApiOperation(value = "欄位資訊列表頁獲取",notes = "")
    public Response<?> DataSettingList(@ModelAttribute DataSettingDTO dataSettingDTO){
        return ResponseUtils.returnApiObjectSuccess(dataSettingBusiness.dataSettingList(dataSettingDTO));
    }
}
 

3、定義全域性錯誤攔截器

@RestControllerAdvice
@Slf4j
public class GlobErrorHandler {

    @ExceptionHandler(MethodArgumentNotValidException.class)
    public Response<?> handleMethodArgumentNotValidException(MethodArgumentNotValidException notValidException){
        StringBuilder errorInfo = new StringBuilder();
        notValidException.getBindingResult().getFieldErrors().forEach(fieldError->{
            if(errorInfo.length()>0){
                errorInfo.append(",");
            }
            errorInfo.append(fieldError.getDefaultMessage());
        });
        log.error(notValidException.getMessage(),notValidException);
        return ResponseUtils.returnCommonException(errorInfo.toString());
    }

    @ExceptionHandler(ConstraintViolationException.class)
    public Response<?> handleConstraintViolationException(ConstraintViolationException constraintViolationException){
        StringBuilder errorInfo = new StringBuilder();
        constraintViolationException.getConstraintViolations().forEach(violation->{
            if(errorInfo.length()>0){
                errorInfo.append(",");
            }
            errorInfo.append(violation.getMessage());
        });
        log.error(constraintViolationException.getMessage(),constraintViolationException);
        return ResponseUtils.returnCommonException(errorInfo.toString());
    }

    @ExceptionHandler(BindException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public Response<?> handOtherException(BindException bindException){
        StringBuilder errorInfo = new StringBuilder();
        bindException.getBindingResult().getFieldErrors().forEach(fieldError->{
            if(errorInfo.length()>0){
                errorInfo.append(",");
            }
            errorInfo.append(fieldError.getDefaultMessage());
        });
        log.error(bindException.getMessage(),bindException);
        return ResponseUtils.returnCommonException(errorInfo.toString());
    }
}
