everybody,i am using boot 2.0.x,project encoding and charset are UTF-8, request and response as same,but when using bean validation 2, to convert error msg,it shows ascii? 1:defined a bean such as 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:using global exception handler:
@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:define 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:write controller to handle request:
@PostMapping("/bv2")
public Boolean jsr380(@Valid @RequestBody BeanValidation bv2) {
return null == bv2 ? false : true;
}
5:start application and request via Postman with request parameter: http://localhost:12345/contextPath/bv2, request data:
{"email":"email address"}
response result:
{
"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"
}
when i using simpled chinese,it appears such as ascii code, how to show or decode to normal such as:
mail address is invalid,邮件地址无效!
mail address is required,邮件地址为必填项!
thank you all!
i resolved it as a global way:
@Configuration
public class WebConfig implements WebMvcConfigurer{
@Override
public Validator getValidator() {
return validator();
}
@Bean
public LocalValidatorFactoryBean validator() {
final LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
validator.setValidationMessageSource(messageSource());
return validator;
}
/**

* [baseName]_[language]
* @return MessageSource

*/
@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;
}
}
bvMsg.properties under src/main/resources/i18n/bvMsg
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!
response,it works as follows:
