使用spring-session把http session放到redis里面

标签：

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>

	</dependencies>

				<configuration>

					<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
