ContainerRequestFilter ContainerResponseFilter不会被调用

我正在尝试通过创建一个小型RESTful服务来学习球衣.我想出于特定原因使用Filters(就像我想使用ContainerResponseFilter for CORS头来允许跨域请求).但是,我只是无法让这些过滤器拦截我的电话.我已经看到了这个问题的所有帖子,他们中的大多数都说要注册注释提供者或web.xml.我已经尝试在web.xml中注册文件以及为@Provider容器提供注释

这是我的web.xml

    
        org.springframework.web.context.ContextLoaderListener
    
    
        contextConfigLocation
        /WEB-INF/classes/spring/config/BeanLocations.xml
    

    
        Jersey Web Application
        com.sun.jersey.spi.container.servlet.ServletContainer
        
            com.sun.jersey.config.property.packages
            com.rest.example
        
          
            jersey.config.server.provider.packages  
            com.rest.example.cors
        
        
            com.sun.jersey.spi.container.ContainerResponseFilters
            com.rest.example.CORSFilter
        
        
            com.sun.jersey.spi.container.ContainerRequestFilters
            com.rest.example.RequestFilter
        

    
    
        Jersey Web Application
        /webresources/*
    

这是我的过滤器:

package com.rest.example.cors;

import javax.ws.rs.ext.Provider;

import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerResponse;
import com.sun.jersey.spi.container.ContainerResponseFilter;

@Provider
public class CORSFilter implements ContainerResponseFilter {

    public ContainerResponse filter(ContainerRequest creq,
            ContainerResponse cresp) {

             cresp.getHttpHeaders().putSingle("Access-Control-Allow-Origin", "*");
             cresp.getHttpHeaders().putSingle("Access-Control-Allow-Credentials", "true");
             cresp.getHttpHeaders().putSingle("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT, OPTIONS, HEAD");
             cresp.getHttpHeaders().putSingle("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With");

            return cresp;
    }
}


package com.rest.example.cors;

import javax.ws.rs.ext.Provider;

import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerRequestFilter;

@Provider
public class RequestFilter implements ContainerRequestFilter {

    public ContainerRequest filter(ContainerRequest request) {
        System.out.println("request filter");
        return request;
    }
}
