Spring Boot 2.0.X屬性異常處理程序響應ascii？

Question

大家，我正在使用引導2.0.x，項目編碼和字符集均為UTF-8，請求和響應相同，但是使用bean驗證2時，轉換錯誤msg，它顯示ascii嗎？ 1：定義一個Bean，例如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：使用全局異常處理程序：

    @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：定義ValidationMessages.properties：

bv2.email.invalid = mail address is invalid,郵件地址無效!
bv2.email.required = mail address is required,郵件地址為必填項!

4：編寫控制器以處理請求：

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

5：通過Postman啟動應用程序並使用請求參數進行請求，請求參數為： http：// localhost：12345 / contextPath / bv2 ，請求數據：

{"email":"email address"}

響應結果：

{
            "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"
        }

6. 它響應成功，但是會自動編碼為ASCII，所以我的問題是：“ defaultMessage”：“郵件地址無效，é\‚®ä»¶å\\ u009c°å\\ u009d \€æ\\ u0097æ\\ u0095 \\ u0088！ ，

當我使用簡體中文時，它會顯示諸如ascii代碼，如何正常顯示或解碼，例如：

mail address is invalid,郵件地址無效!
        mail address is required,郵件地址為必填項!

謝謝你們！

Answer 1

以我的經驗，您可以在文件“ xxx.properties”中執行此操作

bv2.email.invalid = mail address is invalid,é\‚®ä»¶å\œ°å\\€æ\— æ\•\ˆ!

Answer 2

在屬性文件中定義默認編碼類型。

嘗試使用

spring.messages.encoding=UTF-8

在application.properties文件中。

Answer 3

我以全球性方式解決了它：

@Configuration

公共類WebConfig實現WebMvcConfigurer {

@Override
public Validator getValidator() {
    return validator();
}

@Bean
public LocalValidatorFactoryBean validator() {
    final LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
    validator.setValidationMessageSource(messageSource());
    return validator;
}

/**
 * @title:messageSource:base name sequence:i18n and bean validation use this
 * [baseName]_[language]_[script]_[region]_[variant]
 * [baseName]_[language]_[script]_[region]
 * [baseName]_[language]_[script]
 * [baseName]_[language]_[region]_[variant]
 * [baseName]_[language]_[region]
 * [baseName]_[language]
 * @return MessageSource
 * @create 2018-09-25 09:32:24
 * @author:elf
 * @since:1.0.0
 */
@Bean
public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource source = new ReloadableResourceBundleMessageSource();
    String[] baseNameArray = {
        "classpath:i18n/msg",
        "classpath:i18n/bvMsg",
        "classpath:i18n/commonMsg",
    };
    source.setBasenames(baseNameArray);
    source.setDefaultEncoding(StandardCharsets.UTF_8.name());
    return source;
}

}

src / main / resources / i18n / bvMsg下的bvMsg.properties

bv2.price.min = 最低價格是666!
bv2.price.positive = 價格必須是正數!

bv2.email.invalid = 郵件地址無效!
bv2.email.required = 郵件地址為必填項!

響應，其工作方式如下：
