本文主要是介绍Java去掉 URL 中的 jsessionid，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

import javax.servlet.*;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpServletResponseWrapper;

import javax.servlet.http.HttpSession;

import java.io.IOException;

public class DisableUrlSessionFilter implements Filter {

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        // skip non-http requests

        if (!(request instanceof HttpServletRequest)) {

             chain.doFilter(request, response);

            return;

         }

         HttpServletRequest httpRequest = (HttpServletRequest) request;

         HttpServletResponse httpResponse = (HttpServletResponse) response;

        // clear session if session id in URL

        if (httpRequest.isRequestedSessionIdFromURL()) {

             HttpSession session = httpRequest.getSession();

            if (session != null) session.invalidate();

         }

        // wrap response to remove URL encoding

         HttpServletResponseWrapper wrappedResponse = new HttpServletResponseWrapper(httpResponse) {

             @Override

            public String encodeRedirectUrl(String url) {

                return url;

             }

            public String encodeRedirectURL(String url) {

                return url;

             }

            public String encodeUrl(String url) {

                return url;

             }

            public String encodeURL(String url) {

                return url;

             }

         };

        // process next request in chain

         chain.doFilter(request, wrappedResponse);

     }

    /**

    public void init(FilterConfig config) throws ServletException {

     }

    /**
