Jersey Response Filter
提问by user3218089
I am trying to create a jersey filter that filters all the server's responses of 500 error.
我正在尝试创建一个球衣过滤器来过滤所有服务器的 500 错误响应。
But I dont know much about filters so I just started some code but I have no idea how to continue...can anybody help me with this issue.
但我对过滤器了解不多，所以我刚开始写一些代码，但我不知道如何继续……有人能帮我解决这个问题吗？
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
}
and my web.xml looks like this
我的 web.xml 看起来像这样
<servlet>
<servlet-name>Authenticator</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.spi.container.ResourceFilters</param-name>
<param-value>com.query.displayer.Filters</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Authenticator</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

You're mixing 2 versions of Jersey in your application: Implementation of a ContainerRequestFilterfrom JAX-RS 2.0 (Jersey 2) and descriptor configuration (web.xml) for Jersey 1 (see prefix com.sun.jersey). The following article explains how to register providers in Jersey 2:
您在应用程序中混合了 2 个 Jersey 版本：JAX-RS 2.0 (Jersey 2)的ContainerRequestFilter 的实现和 Jersey 1 的描述符配置 (web.xml)（请参阅前缀com.sun.jersey）。以下文章解释了如何在 Jersey 2 中注册提供者：
It seems that you we're using ResourceFilterFactoryin Jersey 1. This concept doesn't exist in Jersey 2 but there is a new concept (directly in JAX-RS 2.0) how to do that:
我们似乎ResourceFilterFactory在 Jersey 1 中使用了您。 Jersey 2 中不存在此概念，但有一个新概念（直接在 JAX-RS 2.0 中）如何做到这一点：

When you are using Jersey-2 you must use the follow configuration to register your filter into the web.xml
当您使用 Jersey-2 时，您必须使用以下配置将过滤器注册到 web.xml 中
jersey.config.server.provider.classnames
jersey.config.server.provider.classnames
instead of
代替
com.sun.jersey.spi.container.ContainerRequestFilters(jersey-1x)
com.sun.jersey.spi.container.ContainerRequestFilters(jersey-1x)
<!-- This is the config needed -->
<servlet>
//...
<init-param>
<param-name>jersey.config.server.provider.classnames</param-name>
<param-value>com.your_package_path.yourClassFilter</param-value>
</init-param>
//...
</servlet>
