来源:互联网 发布:阿加莎克里斯蒂知乎 编辑:程序博客网 时间:2024/06/06 14:28
环境准备:
nginx:http://nginx.org/download/nginx-1.6.0.zip
tomcat7:http://mirrors.hust.edu.cn/apache/tomcat/tomcat-7/v7.0.54/bin/apache-tomcat-7.0.54.zip
memcached:http://www.memcached.org/files/memcached-1.4.20.tar.gz
所需jar包:
javolution-5.5.1.jar
memcached-session-manager-1.8.1.jar
memcached-session-manager-tc7-1.8.1.jar
msm-javolution-serializer-1.8.1.jar
spymemcached-2.10.2.jar
tomcat7的server.xml配置如下:

context.xml的配置如下:
<Manager transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory" copyCollectionsForSerialization="false" sessionBackupTimeout="1800000" sessionBackupAsync="false" requestUriIgnorePattern=".*\.(png|gif|jpg|css|js|ico|jpeg|htm|html)$" memcachedNodes="n1:192.168.0.37:10000" className="de.javakaffee.web.msm.MemcachedBackupSessionManager"/>
每一个tomcat的server.xml注意端口号port标示不能是一样的,然后那个memcachedNodes写的是memcached的服务地址;
上面准备jar包放在tomcat的lib文件夹里面 执行即可
memcached:无需什么配置,按照要求来做即可。网上百度一下一大堆。
nginx配置:
upstream localhost { server localhost:18080; server localhost:28080; server localhost:38080; } server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { index index.jsp; proxy_pass http://localhost; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }
配置完毕,启动tomcat和ngnix,即可查看结果了。
编写俩个jsp文件,MyJsp.jsp 和abc.jsp
MyJsp.jsp内容如下
<body> This is my JSP page. <% out.print(request.getSession().getId()); session.setAttribute("abc","1234566"); out.print(session.getAttribute("abc")); %><br> </body>
abc.jsp内容如下
<body> This is my JSP page. <% out.print(request.getSession().getId()+"---------"+request.getSession().getAttribute("abc")); %><br> </body>
测试结果:
先访问MyJsp.jsp页面
然后访问abc.jsp页面
sessionId一致,并且如期访问到session里面的值,表示调试成功
