redis與spring的集成

首先須要安裝redis

烏班圖的安裝   apt-get install redis-server

而後是修改 /etc/redis/redis.conf  文件 修改裏面的 bind 127.0.0.1 改爲你的外網ip這樣 外網才能訪問

而後/etc/init.d/redis-server restart

 

客戶端與spring集成 須要一下jar包

下載後配置applicationContext.xml spring的配置文件

加入(注意 sentinels的地址是你客戶端的地址 不要與jedisConnFactory中的服務器端地址搞混)

    <bean id="redisSentinelConfiguration"
          class="org.springframework.data.redis.connection.RedisSentinelConfiguration">
          <property name="master">
              <bean class="org.springframework.data.redis.connection.RedisNode">
                  <property name="name" value="mymaster"></property>
              </bean>
          </property>
          <property name="sentinels">
              <set>
                <bean class="org.springframework.data.redis.connection.RedisNode">
                     <constructor-arg index="0" value="192.168.1.18" />
                     <constructor-arg index="1" value="7031" />                    
                 </bean>
              <!--    <bean class="org.springframework.data.redis.connection.RedisNode">
                     <constructor-arg index="0" value="10.6.1**.**6" />
                     <constructor-arg index="1" value="7031" />                
                 </bean>
                 <bean class="org.springframework.data.redis.connection.RedisNode">                    
                     <constructor-arg index="0" value="10.6.1**.**1" />
                     <constructor-arg index="1" value="7031" />                
                 </bean> -->
             </set>
         </property>
     </bean>
 
      <bean id="jedisConnFactory"
         class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
         <property name="hostName" value="115.XX.XXX.XX"/>
        <property name="port" value="6379"/>
        <property name="usePool" value="false"/>
        <constructor-arg ref="redisSentinelConfiguration"/>
     </bean>
 
     <bean id="RedisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
         <property name="connectionFactory" ref="jedisConnFactory" />
     </bean>

而後再程序中能夠這樣調用

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    @RequestMapping("/selecttest")
    @ResponseBody
    public String selecttest(HttpServletRequest request) {
        redisTemplate.opsForValue().set("name", "周小帥");
        System.out.println(redisTemplate.opsForValue().get("name"));
        return redisTemplate.opsForValue().get("name");
        
        
    }

感受和memached的集成差很少 可是 據說redis的功能要強大的許多，，，繼續研究中

後續補充：

另外一種簡單的xml實現方式

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:use-pool="true"
	    p:host-name="IP" p:port="6379" p:password="XXXX" />
		  <!-- redis template definition -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" p:connection-factory-ref="jedisConnectionFactory"/>

實現代碼map取值
