使用spring-session把http session放到redis里面

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;    @EnableRedisHttpSession  public 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"));

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
