基于 spring session 的单点登录

1、pom.xml 添加依赖

    <dependency>
      <groupId>org.springframework.sessiongroupId>
      <artifactId>spring-session-data-redisartifactId>
      <version>1.2.0.RELEASEversion>
    dependency>

2、在 web.xml 中添加过滤器

    <filter>
        <filter-name>springSessionRepositoryFilterfilter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxyfilter-class>
    filter>
    <filter-mapping>
        <filter-name>springSessionRepositoryFilterfilter-name>
        <url-pattern>*.dourl-pattern>
    filter-mapping>

3、在 spring.xml 添加配置

    <bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
     	
        <property name="maxInactiveIntervalInSeconds" value="1800" />
    bean>

    <bean id="defaultCookieSerializer" class="org.springframework.session.web.http.DefaultCookieSerializer">
    	
        <property name="domainName" value=".happymmall.com" />
        <property name="useHttpOnlyCookie" value="true" />
        <property name="cookiePath" value="/" />
        <property name="cookieMaxAge" value="31536000" />
    bean>

    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="20"/>
    bean>

    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
         
        <property name="hostName" value="127.0.0.1" />
        <property name="port" value="6379" />
        <property name="poolConfig" ref="jedisPoolConfig" />
    bean>

4、直接用 HttpSession 就可以获取信息了

 	@RequestMapping(value = "login.do",method = RequestMethod.POST)
    @ResponseBody
    public ServerResponse<User> login(String username, String password, HttpSession session, HttpServletResponse httpServletResponse){
        ServerResponse<User> response = iUserService.login(username,password);
        if(response.isSuccess()){
            session.setAttribute(Const.CURRENT_USER,response.getData());
        }
        return response;
    }
