同域名同项目名session共享

7.创建设置session的Controller
@Controller
public class TestController {
@RequestMapping("set")
@ResponseBody
public Object set(HttpServletRequest request){
request.getSession().setAttribute("mykey","my value");
return "ok";
}
}
8.修改index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page language="java" import="java.text.SimpleDateFormat"%>
<%
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("YYYY-MM-dd HH:mm:ss");
String date=simpleDateFormat.format(new Date());
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>tomcat1</title>
</head>
<body>
SessionID:<%=session.getId()%>
<BR>
当前时间为:<%=date%>
<BR>
SessionPort:<%=request.getServerPort()%>
<BR>
mykey的值为：<%=session.getAttribute("mykey")%>
<BR>
<%
out.println("这是tomcat1");
%>
</body>
</html>
部署第二个Tomcat2项目时修改index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page language="java" import="java.text.SimpleDateFormat"%>
<%
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("YYYY-MM-dd HH:mm:ss");
String date=simpleDateFormat.format(new Date());
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>tomcat2</title>
</head>
<body>
SessionID:<%=session.getId()%>
<BR>
当前时间为:<%=date%>
<BR>
SessionPort:<%=request.getServerPort()%>
<BR>
mykey的值为：<%=session.getAttribute("mykey")%>
<BR>
<%
out.println("这是tomcat2");
%>
</body>
</html>
测试
1.部署后访问Tomcat1的index.jsp页面和Tomcat2的index.jsp页面
此时两个项目的Session内容完全一样，mykey都没有值
2.调用设置session的接口
3.再次访问Tomcat1的index.jsp页面和Tomcat2的index.jsp页面
此时两个项目的mykey的值是一样的。说明两个项目session共享
同域名不同项目名session共享
1.修改application-session.xml
<?xml version="1.0" encoding="UTF-8"?>

<!--读取redis.properties属性配置文件-->
<context:property-placeholder location="classpath:redis.properties"/>
<!-- 配置jedis连接工厂，用于连接redis -->
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="${redis.hostName}"/>
<property name="port" value="${redis.port}"/>
<property name="password" value="${redis.password}"/>
<property name="usePool" value="${redis.usePool}"/>
<property name="timeout" value="${redis.timeout}"/>
</bean>
<bean id="httpSessionStrategy" class="org.springframework.session.web.http.CookieHttpSessionStrategy">
<!--使用cookie策略-->
<property name="cookieSerializer" ref="cookieSerializer"/>
</bean>
<bean id="cookieSerializer" class="org.springframework.session.web.http.DefaultCookieSerializer">
<!--指定cookie的域名及路径-->
<property name="cookiePath" value="/"/>
</bean>
</beans>
2.修改两个项目名分别为nginx-dome和nginx，也就是war包名为nginx-dome.war和nginx.war
