    @POST
    @Path("")
    @Consumes({"application/x-www-form-urlencoded"})
    TokenDTO login(@ApiParam(value = "The id of the channel used", required = true )  @HeaderParam("channel")  @NotEmpty(message = "email.notempty") String channel) throws Exception;

大家好,我正在尝试验证通道参数,所以它不为空。如果我将它解析为空,它只会抛出我:

{
"code": 26,
"message": "Validation Error: :NotEmpty",
"data": [
    {
        "type": "NotEmpty",
        "property": "",
        "value": null,
        "inputType": "body",
        "attributes": null
    }
],
"source": "XXXX",
"type": "ValidationException",
"guid": "965ee91a-99a1-4ae5-b721-6415a80dad23"
}

您能告诉我如何自定义验证错误消息吗?

编辑:我看过很多文章描述我如何自定义“字段”验证的消息。但我想验证一个方法参数。

在你的参数中确保添加花括号,所以它会是这样的

@NotEmpty(message = "{email.notempty}") String email

然后,在应用程序配置中定义 LocalValidatorFactoryBean:

   @Bean
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("classpath:ValidationMessages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }

    @Bean
    @Override
    public Validator getValidator() {
        LocalValidatorFactoryBean bean = new LocalValidatorFactoryBean();
        bean.setValidationMessageSource(messageSource());
        return bean;
    }

最后,在类路径中创建一个 ValidationMessages.properties 文件,其中包含:

email.notempty=E-mail address is required
