去掉 URL 中讨厌的 jsessionid
编写DisableUrlSessionFilter.java类
?
package com.cheney.util;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); } /** * Unused. */ public void init(FilterConfig config) throws ServletException { } /** * Unused. */ public void destroy() { }}?
配置在web.xml中
<filter> <filter-name>jsessionid</filter-name> <filter-class> com.haoxingtong.web.web.filter.DisableUrlSessionFilter </filter-class></filter><filter-mapping> <filter-name>jsessionid</filter-name> <url-pattern>/*</url-pattern></filter-mapping>?
