Jersey ContainerRequestFilter未触发

Question

我正在尝试使用a ContainerRequestFilter在基于Tomcat的Jersey应用程序上强制执行某些身份验证.我按照这个文件.问题:永远不会触发过滤器

过滤类:

@Provider
public class AuthFilter implements ContainerRequestFilter {

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

        // MY AUTHENTICATION CODE GOES HERE

    }

web.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

      <param-value>com.hck.debate.rest.controller</param-value>  
    </init-param>  
    <init-param>  
        <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>

  <servlet-mapping>  
    <servlet-name>Jersey REST Service</servlet-name>  
    <url-pattern>/*</url-pattern>  
  </servlet-mapping>

Answer 1

好吧,我没有得到jersey.config.server.provider.packagesinit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.

它现在有效:

<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>

Answer 2

我还必须将@Provider JAX-RS注释添加到我的过滤器中.
这使得在JAX-RS扫描阶段可以发现滤波器.

@Provider
public class MyAppFilter implements ContainerRequestFilter {
    // filter logic
}

Answer 3

一些提示:

1. 确保您使用的是JAX-RS 2.17版.

2. 确保您在过滤器中使用正确的导入:

   • import javax.ws.rs.container.ContainerRequestContext;
   • import javax.ws.rs.container.ContainerRequestFilter;

3. 添加@Provider注释
