SpringMVC-Session

该项目是基于SpringMVC，集成Spring-Session实现Session共享
这种方式比Tomcat插件方式更好，所以推荐大家使用
未来几天出一版Spring-Boot的

集成步骤

第一步. 搭建SpringMVC项目

这一步我就不多说了网上很多例子自己按例子搭建就好了，也可以按照我这个搭建

第二步. Maven引入依赖

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
    <version>1.3.1.RELEASE</version>
</dependency>

这个依赖其实是依赖了另外四个，这个下载下来是空的

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.4.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.5.2</version>
</dependency>

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session</artifactId>
    <version>1.0.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.2</version>
</dependency>

如果不是使用maven构建项目的话，使用jar包，需要下载这四个jar

第三步. 新建spring-session配置文件（我的项目中对应的是spring-session-redis.xml）

在其中加入以下配置

<beans>
<!-- 引入redis配置 -->
    <context:property-placeholder location="classpath:redis.properties" ignore-unresolvable="true"/>
    <context:annotation-config />
    <!--这里添加的是Redis，因为使用的是Spring里自带的Redis的Session策略 -->
    <bean id="redisConnectionFactory"
            class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
            p:host-name="${redis.host}"
            p:port="${redis.port}"
            p:password="${redis.pass}"
            p:use-pool="true"
            p:database="8" />

    <bean id="stringRedisSerializer"
            class="org.springframework.data.redis.serializer.StringRedisSerializer" />

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"
          p:connection-factory-ref="redisConnectionFactory"
          p:keySerializer-ref="stringRedisSerializer" p:valueSerializer-ref="stringRedisSerializer"
          p:hashKeySerializer-ref="stringRedisSerializer"
          p:hashValueSerializer-ref="stringRedisSerializer" />
    <!-- 这里的是为了下面的 Session策略过滤器提供构造函数传入的参数，因为Session过滤器要依赖该对象来构造，所以创建一个先 -->
    <bean name="redisOperationsSessionRepository"
          class="org.springframework.session.data.redis.RedisOperationsSessionRepository">
        <constructor-arg ref="redisConnectionFactory"/>
    </bean>

    <!-- 这个是Session策略过滤器，即将容器原有的Session持久化机制，代替为Spring的 Redis持久化Session机制。 -->
    <!-- 注意，这个名字与 web.xml里的targetBean的下value是要一致的。 -->
    <bean name="springSession"
          class="org.springframework.session.web.http.SessionRepositoryFilter">
        <constructor-arg ref="redisOperationsSessionRepository"/>
    </bean>
</beans>

第四步. 在web.xml中添加配置

再web.xml文件中加入以下配置

<filter>
    <filter-name>spring-session</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    <init-param>
        <param-name>targetBeanName</param-name>
        <param-value>springSession</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>spring-session</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

第五步. 测试

//测试一、向session中放入实现序列化的实体类（我这儿是TestEntity）
TestEntity testEntity= new TestEntity();
testEntity.setUsername("david_zh");
testEntity.setTrueName("TrueName");
request.getSession().setAttribute("testEntity", testEntity);

//测试二、向session中放入String字符串
request.getSession().setAttribute("testString", "i am a string value!");

注意向session中放对象的时候，这个对象必须实现序列化接口，否则session保存不到redis中，具体原因请百度redis

至此，spirngmvc + spring-session 的集成就完了，有问题可以联系我

我有那儿写的不好的希望大家指出，共同进步
