JSP 開(kāi)發(fā)之Servlet解決網(wǎng)頁(yè)緩存問(wèn)題
（1）我們?yōu)槭裁匆乐褂斡[器頁(yè)面緩存的問(wèn)題：
所以在不需要緩存的頁(yè)面中需要實(shí)現(xiàn)不緩存頁(yè)面；
代碼如下：
package com.lc.HttpTest; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class CacheJiejue extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=utf-8"); //指定該頁(yè)面不緩存 response.setDateHeader("Expires",-1); //IE游覽器支持的 //保證兼容性 response.setHeader("Cache-Control", "no-cache"); response.setHeader("Pragme", "no-cache"); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doGet(request, response); } } （2）但是如果要實(shí)現(xiàn)特定時(shí)間內(nèi)的頁(yè)面緩存 則代碼如下：
package com.lc.HttpTest; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class CacheJiejue extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=utf-8"); //指定該頁(yè)面不緩存 //response.setDateHeader("Expires",-1); //IE游覽器支持的 //緩存一定的時(shí)間 緩存 一天的時(shí)間 response.setDateHeader("Expires",System.currentTimeMillis()+3600*1000*24); //保證兼容性 response.setHeader("Cache-Control", "no-cache"); response.setHeader("Pragme", "no-cache"); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doGet(request, response); } } 以上就是Servlet解決網(wǎng)頁(yè)緩存的實(shí)例詳解，如有疑問(wèn)請(qǐng)留言或者到本站社區(qū)交流討論，感謝閱讀，希望能幫助到大家，謝謝大家對(duì)本站的支持！
