1. The first step is to install redis. My server is Windows. I downloaded the installation-free version. Just decompress it. The directory is as follows. At the beginning, redis does not require a password by default. If you want to set a password, you can go to the redis.windows.conf file and find requirepass, delete the # sign in front, and set the password after it.

2. Enter the root directory of redis from cmd and type the following command: redis-server.exeredis.windows.conf. In this way, redis can be started. If the startup is successful, the following screen will appear. Of course, you can also modify the conf file and add a password. requirepass xxxxx

#3. Next we can do some configuration work to achieve global caching of session data.

1) First, add the jar package. If you are a maven project, you need to add the following code to pom.xml

<!-- redis -->
 <dependency>
  <groupid>org.springframework.session</groupid>
  <artifactid>spring-session-data-redis</artifactid>
  <version>1.3.1.release</version>
  <type>pom</type>
 </dependency>

If it is not a maven project, you need to add the following jar packages.

2) Write redis.properties, the code is as follows

redis_isopen:yes
#主机地址
redis_hostname=xxx.xxx.xxx.xxx
#端口
redis_port=6379
#密码
redis_password=xxxxxxxx
#连接超时时间
redis_timeout=200000
redis_maxidle:300
redis_maxactive:600
redis_maxwait:100000
redis_testonborrow:true

is basically similar to the connection statement for our configuration database.

3) Write the spring-redis.xml configuration file. This file configures some basic information about redis.

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
 xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
 xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd ">
 <!-- session设置 maxinactiveintervalinseconds为session的失效时间,单位为秒-->
 <bean
 class="org.springframework.session.data.redis.config.annotation.web.http.redishttpsessionconfiguration">
 <property name="maxinactiveintervalinseconds" value="3600"></property>
 </bean>
 <!-- redis连接池 -->
 <bean id="poolconfig" class="redis.clients.jedis.jedispoolconfig">
 <property name="maxidle" value="${redis_maxidle}" />
 <property name="testonborrow" value="${redis_testonborrow}" />
 </bean>
 <!-- redis连接工厂 -->
 <bean id="connectionfactory"
 class="org.springframework.data.redis.connection.jedis.jedisconnectionfactory">
 <property name="hostname" value="${redis_hostname}" />
 <property name="port" value="${redis_port}" />
 <property name="password" value="${redis_password}" />
 <property name="timeout" value="${redis_timeout}" />
 <property name="poolconfig" ref="poolconfig"></property>
 </bean>
</beans>

4) In application.xml (spring’s main configuration file), you need to add scanning of the redis.properties configuration file, as follows.

<!-- 读取redis参数配置 -->
 <bean id="propertyconfigurer"
 class="org.springframework.beans.factory.config.propertyplaceholderconfigurer">
 <property name="locations">
  <list>
  <value>/web-inf/classes/redis.properties</value>
  </list>
 </property>
 </bean>

5) Introduce spring-redis.xml into the main configuration file, as follows.

<import resource="spring-redis.xml" />

6) In web.xml, add a filter about the session. Only in this way will the session be manipulated by redis.

<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>

After this, we will realize the management of session by redis.

7) We can install a redis client to view the data inside, called redis desktop manager. As shown below, it is very useful and you can see the data in the redis database.

#ps. When you exit again, you need to write like this to avoid errors. (ssh project)

public string yipinexit(){
 iterator<string>keys=session.keyset().iterator();
 while(keys.hasnext()){
  string key=keys.next();
  session.remove(key);
 }
 return "yipinexit";
 }
