1 引入

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

2 Controller 中使用

    @PostMapping("/testval")
    public Object testVal(@Validated @RequestBody TGiftPO po){
//        var r = extSchoolMService.sync();
        return Result.success(po);
    }

3 PO 中進(jìn)行標(biāo)記

@Data
public class TGiftPO {

    @NotNull(message = "title 不可為空")
    String title;

    String img;

    Integer score;

}

全局異常類(lèi)中進(jìn)行捕捉

import com.adea.tool.result.Result;
import com.adea.tool.result.ResultCode;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.HttpStatus;
import org.springframework.validation.BindingResult;
import org.springframework.validation.FieldError;
import org.springframework.validation.ObjectError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.ResponseStatus;
import java.util.List;


@Slf4j
@ControllerAdvice
public class ValidatedExceptionHandler {

    @ResponseBody
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(MethodArgumentNotValidException.class)
    public Result exceptionHandler(MethodArgumentNotValidException exception){
        BindingResult result = exception.getBindingResult();
        StringBuilder stringBuilder = new StringBuilder();
        if (result.hasErrors()){
            List<ObjectError> errors = result.getAllErrors();
            if (errors != null){
                errors.forEach(p ->{
                    FieldError fieldError = (FieldError) p;
                    stringBuilder.append(fieldError.getDefaultMessage());
                });
            }
        }

        return Result.error(ResultCode.USER_PARAM_ERROR,stringBuilder.toString());
    }

}

axios 的配置

          if(error.response.data  &&  error.response.data.message){
                ElMessage({
                    message: error.response.data.message,
                    type: 'error',
                    duration: 3 * 1000
                })
            }
