springboot 验证信息国际化
1.准备entity 属性用@NotBlank(
message="{error.name}")
2.controller 入参
@Valid User
3.项目中加入
GlobalExceptionHandler
4.在resources目录下增加 ValidationMessages.properties ValidationMessages_en_US.properties ValidationMessages_zh_CN.properties
若要自定义文件位置或名称则需要重写WebMvcConfigurerAdapter 的 getValidator 方法
代码见 MyConfigureation
@Configuration
public class
MyConfigureation extends WebMvcConfigurerAdapter {
public ResourceBundleMessageSource getMessageSource() throws Exception {
ResourceBundleMessageSource rbms = new ResourceBundleMessageSource();
rbms.setDefaultEncoding("UTF-8");
rbms.setBasenames("
i18n/error/ValidationMessages"); // 此为文件目录
ValidationMessages是文件名
rbms.setCacheSeconds(10);
return rbms;
}
@Bean
@Override
public Validator getValidator() {
LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
try {
validator.setValidationMessageSource(getMessageSource());
} catch (Exception e) {
e.printStackTrace();
}
return validator;
}
}
@ControllerAdvice
@RestController
public class
GlobalExceptionHandler implements ErrorController {
private Logger logger = LoggerFactory.getLogger(GlobalExceptionHandler.class);
@ExceptionHandler(value = Exception.class)
@RequestMapping("/error")
public Result defaultErrorHandler(HttpServletRequest req, Exception ex) throws Exception {
logger.error("", ex);
String result = "";
if (ex instanceof BindException) {
BindException bindException = (BindException) ex;
for (FieldError fieldErro : bindException.getBindingResult().getFieldErrors()) {
result += "【" + fieldErro.getField() + ":" + fieldErro.getDefaultMessage() + "】";

}

HttpRequestMethodNotSupportedException httpRequestMethodNotSupportedException = (HttpRequestMethodNotSupportedException) ex;

result = "缺少必要的参数[" + missingServletRequestParameterException.getMessage() + "]";
} else {
result = "Error handling OR Service unavaliable at client01";
}
return new Result(1, result);
}
public String getErrorPath() {
return "/error";
