Jersey ContainerRequestFilter 未触发

Question

我正在尝试使用 ContainerRequestFilter 对基于 Tomcat 的 Jersey 应用程序强制执行某些身份验证。我关注了this document 。问题:过滤器永远不会被触发

过滤器类别:

@Provider
public class AuthFilter implements ContainerRequestFilter {

    @Override
    public void filter(ContainerRequestContext requestContext)
        throws IOException {

        // MY AUTHENTICATION CODE GOES HERE

    }

web.xml 文件:

好吧，我不知道 jersey.config.server.provider.packages 初始化参数不仅需要引用服务类(API 端点)，还需要引用包括过滤器在内的所有类。

现在可以了:

<init-param>  
  <param-name>jersey.config.server.provider.packages</param-name>  
  <param-value>com.hck.debate.rest.controller;com.hck.debate.rest.security</param-value>
</init-param>
<init-param>
    <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>
    <param-value>com.hck.debate.rest.security.AuthFilter</param-value>
</init-param>
