Redis shared session under Nginx load Balancing (Java) (ii)

On the question of the session on the Internet has various aspects of the target, there is in Nginx processing: Ip_hash session, there is in Tomcat do processing: Modify the context file, there is a project to do processing. This article deals with the project

1, first of all my project is with Maven (if not with Maven can download), the use of the jar package has the following:

2. Configure Spring configuration file Applicationcontext-redis.xml

<context:annotation-config/> <context:property-placeholder location= "Classpath:redis.properties"/> & Lt;bean id= "Redishttpsessionconfiguration"class= "Org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration" > < Property Name= "Maxinactiveintervalinseconds" value= "3600"/> </bean> <bean id= "Jedispoolconfig"class= "Redis.clients.jedis.JedisPoolConfig" > <property name= "maxtotal" value= "+"/> <property name= "Maxidle" value= "ten"/> </bean> <bean id= "Jedisconnectionfactory"class= "Org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method= "Destroy" > < Property Name= "HostName" value= "${redis.host}"/> <property name= "port" value= "${redis.port}"/> < Property name= "Password" value= "${redis.pass}"/> <property name= "Timeout" value= "+"/> <prope Rty name= "Usepool" value= "true"/> <property name= "poolconfig" ref= "Jedispoolconfig"/> </bean>

3. Web. XML Join

<filter>    <filter-name>springSessionRepositoryFilter</filter-name>    <filter-  Class>org.springframework.web.filter.delegatingfilterproxy</filter-class>  </ filter>  <filter-mapping>    <filter-name>springSessionRepositoryFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>  < context-param>    <param-name>contextConfigLocation</param-name>    <param-value> classpath*:applicationcontext*.xml</param-value>  </context-param>  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </ Listener>

5. Successful interface

Three servers

ip:10.13.5.10 as a Load balancer server and Redis server

ip:10.13.5.11 Project Server 01

ip:10.13.5.12 Project Server 02

First comparison: Two servers with different IP

Second contrast (store value to session):

such as the above two groups of pictures, where SessionID has not changed, Redis in the

Finally, note the following:

1, must ensure that nginx.conf in the location/{}, '/' after the addition of any URI added will not be implemented.

2, must ensure that the same project, even if just changed the HTML of several characters, sometimes session sharing or will expire!!!
