Java：找出哪个类处理哪个URL调用

Question

我需要为我的Jersey代码制作一个自定义过滤器......所以，在这个类中

package com.test.security;

@Path("/secured")
public class Test {
    @POST
    public void postData() {}
}

我想在下面创建这个类，找出哪个类处理/secured

public class SecurityFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    //
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest http = (HttpServletRequest) request;
        System.out.println("session: " + http.getSession().getId());
        System.out.println("method: " + http.getMethod());
        System.out.println("url: " + http.getContextPath());
        System.out.println("class handler: " + <?????> );
        chain.doFilter(request, response);
    }

    @Override
    public void destroy() {
    //
    }

}

那应该输出

method: POST
url: /secured
class handler: com.test.security.Test

简而言之，当客户端请求URL时，我想找出哪个类负责它。
