如何仅将过滤器注册到一个@RequestMapping 方法? [英] How to register a Filter to one @RequestMapping method only?

问题描述

我为一般内容记录注册了以下过滤器:

I registered the following filter for general content logging:

@Bean
public Filter getLoggingFilter() {
    CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter();
    filter.setIncludeQueryString(true);
    filter.setIncludePayload(true);
    filter.setMaxPayloadLength(5120);
    return filter;
}

此过滤器可捕获任何请求.

This filter catches on any request.

现在我只想将此过滤器应用于一个特定的 @RequestMapping 方法.

Now I'd like to apply this filter to only one specific @RequestMapping method.

问题:这可能吗?

更新:以下 filterbean 在访问路径时会导致 404.

Update: the following filterbean results in a 404 when accessing the path.

@Bean
public FilterRegistrationBean getLoggingFilter() {
    FilterRegistrationBean filter = new FilterRegistrationBean(new CommonsRequestLoggingFilter());
    filter.addUrlPatterns("/rest/my/specific/method/*");
    return filter;
}

推荐答案

你需要一个 FilterRegistrationBean 指定 URL 映射.参考指南.

@Bean
public Filter loggingFilter() {
    CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter();
    filter.setIncludeQueryString(true);
    filter.setIncludePayload(true);
    filter.setMaxPayloadLength(5120);
    return filter;
}

在过滤器定义旁边添加FilterRegistrationBean.

Next to the filter definition add the FilterRegistrationBean.

@Bean
public FilterRegistrationBean loggingFilterRegistration() {
    FilterRegistrationBean registration = new FilterRegistrationBean(loggingFilter());
    registration.addUrlPatterns("/rest/my/specific/method/*");
    return registration;
}

这会将过滤器附加到指定的 URL.另请注意，UrlPatterns 是根 URL 中的模式.因此，如果您的应用程序映射到 /rest 上，则不会调用此过滤器.

This will attach the filter to the specified URL. Also be aware that the UrlPatterns are patterns inside the root URL. So if your application is mapped on /rest this filter won't be invoked.
