一：

新建maven的webapp项目，加入spring session的相关依赖

pom.xml 如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">		<modelVersion>4.0.0</modelVersion>	<groupId>com.lala</groupId>	<artifactId>leshop</artifactId>	<packaging>war</packaging>	<version>0.0.1-SNAPSHOT</version>		<name>taobao Maven Webapp</name>	<url>http://maven.apache.org</url>		<dependencies>		<dependency>			<groupId>junit</groupId>			<artifactId>junit</artifactId>			<version>4.10</version>			<scope>test</scope>		</dependency>		<dependency>			<groupId>javax.servlet</groupId>			<artifactId>jsp-api</artifactId>			<version>2.0</version>			<scope>provided</scope>		</dependency>		<dependency>			<groupId>javax.servlet</groupId>			<artifactId>javax.servlet-api</artifactId>			<version>3.0.1</version>			<scope>provided</scope>		</dependency>		<dependency>			<groupId>org.springframework.session</groupId>			<artifactId>spring-session-data-redis</artifactId>			<version>1.0.1.RELEASE</version>		</dependency>		<dependency>			<groupId>org.springframework</groupId>			<artifactId>spring-web</artifactId>			<version>4.1.6.RELEASE</version>		</dependency>		<dependency>			<groupId>org.springframework.session</groupId>			<artifactId>spring-session</artifactId>			<version>1.0.1.RELEASE</version>		</dependency>		<dependency>			<groupId>com.orange.redis-embedded</groupId>			<artifactId>embedded-redis</artifactId>			<version>0.6</version>		</dependency>	</dependencies>	<build>		<finalName>leshop</finalName>		<plugins>			<plugin>				<groupId>org.apache.maven.plugins</groupId>				<artifactId>maven-compiler-plugin</artifactId>				<version>3.3</version>				<configuration>					<source>1.8</source>					<target>1.8</target>					<verbose>true</verbose>				</configuration>			</plugin>		</plugins>	</build></project>

二：

配置redis环境

1：安装redis，启动

2：

package com.lala.config;import org.springframework.context.annotation.Bean;import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;@EnableRedisHttpSessionpublic class SessionConfig {	@Bean	public JedisConnectionFactory connectionFactory()	{		JedisConnectionFactory connection = new JedisConnectionFactory();		connection.setPort(6379);		connection.setHostName("192.168.1.106");		return connection;	}}

package com.lala.config;import org.springframework.session.web.context.AbstractHttpSessionApplicationInitializer;public class SessionInitializer extends AbstractHttpSessionApplicationInitializer {	public SessionInitializer() 	{		super(SessionConfig.class);	}}

三：

最后，在servlet或者action里面

Integer uid = Integer.valueOf(req.getParameter("uid"));req.getSession().setAttribute("user", new User(uid, "张三", "这里是redis的"));

执行之后，发现session已经保存在redis里面了。

这种做法，不需要依赖具体的容器。放到任何容器里面都可以使用。

不像网上的做法，使用其他的jar,还需要配置tomcat。这种做法，不支持其他的web server

Spring session redis
