Spring 2.0.X属性异常处理程序响应ascii？
Spring 2.0.X属性异常处理程序响应ascii？
提问于 2018-09-22 01:59:35
各位，我使用的是引导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来转换错误消息时，它会显示ascii? 1:定义了一个bean，比如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:编写控制器来处理请求：
@PostMapping("/bv2")
public Boolean jsr380(@Valid @RequestBody BeanValidation bv2) {
return null == bv2 ? false : true;
}5:通过邮递员启动应用程序和请求，请求参数为：http://localhost:12345/contextPath/bv2，请求数据：
{"email":"email address"}答复结果：
{
"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\u009c°u009d\u0080\u0097\u 0095\u 0088！”，
当我使用简单的中文时，它会出现如ascii代码，如何显示或解码为正常，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！

我把它作为一种全球性的方式解决了：
@Configuration公共类WebConfig实现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 = 最低价格是666!
bv2.price.positive = 价格必须是正数!
bv2.email.invalid = 邮件地址无效!
bv2.email.required = 邮件地址为必填项!答复如下：

根据我的经验，您可以在文件“xxx.properties”中这样做
bv2.email.invalid = mail address is invalid,é\u0082®ä»¶å\u009c°å\u009d\u0080æ\u0097 æ\u0095\u0088!

在属性文件中定义默认编码类型。
试着使用
spring.messages.encoding=UTF-8在application.properties文件中。
