| @RestController
@RequestMapping("/v1/jx/flowSummary")
@Slf4j
public class JxFlowSummaryController {
@Operation(summary = "批量修改原始得分")
@PostMapping("/updateScore")
public ResponseDto batchUpdateScore(@RequestBody @Valid List<BatchUpdateScoreDto> dtoList) {
return ResponseUtil.wrapSuccess(null);
}
}
|
解决方法一：在controller上加上@Validated注解

public class JxFlowSummaryController {
@Operation(summary = "批量修改原始得分")
@PostMapping("/updateScore")
public ResponseDto batchUpdateScore(@RequestBody @Valid List<BatchUpdateScoreDto> dtoList){
return ResponseUtil.wrapSuccess(null);
}
}

解决方法一：校验效果如下
解决方法二：自定义实现一个ValidatedList，接口参数使用ValidatedList

解决方法二：校验效果如下
附：校验基本数据类型和String类型的方法参数时也需要在类上加@Validated
