java - Spring boot 2.0.X属性异常处理程序响应ascii？

Question

各位，我使用的是boot 2.0.x，项目编码和字符集都是UTF-8， 请求和响应相同，但是当使用bean验证2时， 转换错误消息，它显示ascii？1:定义一个bean如BeanValidation.java:

@Data
public class BeanValidation implements Serializable{
    private static final long serialVersionUID = 6265504102271769397L;
    @Email(message = "{bv2.email.invalid}")
    @NotEmpty(message = "{bv2.email.required}")
    private String email;
}

2:使用全局异常处理程序:

    @RestControllerAdvice
public class GenericExceptionHandler 
    extends ResponseEntityExceptionHandler 
    implements ErrorController{
    @Override
    protected ResponseEntity<Object> handleMethodArgumentNotValid1(
        MethodArgumentNotValidException ex,
        HttpHeaders headers,HttpStatus status,WebRequest request) {
        BindingResult br = ex.getBindingResult();
        List<String> errorList = new ArrayList<String>();
        br.getFieldErrors().forEach(fe -> {
            errorList.add(fe.getField() + ":" + fe.getDefaultMessage());
        });
        br.getGlobalErrors().forEach(ge -> {
            errorList.add(ge.getObjectName() + ":" + ge.getDefaultMessage());
        });
        ApiError apiError = new ApiError(HttpStatus.BAD_REQUEST, ex.getLocalizedMessage(), errorList);
        return handleExceptionInternal(ex, apiError, headers, apiError.getStatus(), request);
    }
}

3:定义ValidationMessages.properties:

bv2.email.invalid = mail address is invalid,邮件地址无效!
bv2.email.required = mail address is required,邮件地址为必填项!

4:编写 Controller 来处理请求:

@PostMapping("/bv2")
public Boolean jsr380(@Valid @RequestBody BeanValidation bv2) {
    return null == bv2 ? false : true;
}

5:启动应用程序并通过Postman请求，请求参数: http://localhost:12345/contextPath/bv2 ,请求数据:

{"email":"email address"}

响应结果:

{
            "timestamp": "2018-09-22T01:50:09.729+0000",
            "status": "400",
            "error": "Bad Request",
            "errors": [
                {
                    "defaultMessage": "mail address is invalid,é\u0082®ä»¶å\u009c°å\u009d\u0080æ\u0097 æ\u0095\u0088!",
                    "objectName": "beanValidation",
                    "field": "email",
                    "rejectedValue": "email address",
                    "bindingFailure": false,
                    "code": "Email"
                }
            ],
            "message": "Bad Request",
            "path": "/contextPath/bv2"
        }

它响应成功，但它自动编码ascii，所以我的问题是: "defaultMessage": "邮件地址无效,é\u0082®ä»¶å\u009c°å\u009d\u0080æ\u0097 æ\u0095\u0088!",

当我使用简体中文时，它出现如ascii代码，如何正常显示或解码如:

mail address is invalid,邮件地址无效!
        mail address is required,邮件地址为必填项!

谢谢大家!

根据我的经验，您可以在文件“xxx.properties”中执行此操作

bv2.email.invalid = 邮件地址无效，é\u0082®ä»¶å\u009c°å\u009d\u0080æ\u0097 æ\u0095\u0088!
