基于spring的多redis数据源配置

spring bean

    <bean id="jedisConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="testWhileIdle" value="true" />
        <!-- <property name="maxActive" value="${redis.pool.maxActive}" /> -->
        <property name="maxTotal" value="${redis.pool.maxTotal}" />
        <property name="maxIdle" value="${redis.pool.maxIdle}" />
        <!-- <property name="maxWait" value="${redis.pool.maxWait}" /> -->
        <property name="maxWaitMillis" value="${redis.pool.maxWaitMillis}" />
        <property name="testOnBorrow" value="${redis.pool.testOnBorrow}" />
        <property name="testOnReturn" value="${redis.pool.testOnReturn}" />
    </bean>
    <bean id="jedisPool_xx" class="redis.clients.jedis.JedisPool"
        destroy-method="destroy">
        <constructor-arg ref="jedisConfig" />
        <constructor-arg value="${xx.redis.ip}" />
        <constructor-arg type="int" value="${xx.redis.port}" />
        <constructor-arg value="100000" type="int" />
        <constructor-arg value="${xx.redis.passwd}" />
    </bean>

    <bean id="jedisPool_yy" class="redis.clients.jedis.JedisPool"
        destroy-method="destroy">
        <constructor-arg ref="jedisConfig" />
        <constructor-arg value="${yy.redis.ip}" />
        <constructor-arg type="int" value="${yy.redis.port}" />
        <constructor-arg value="100000" type="int" />
        <constructor-arg value="${yy.redis.passwd}" />
    </bean>

    <!-- 将上方配置的jedisPool加入muyilJedisPoolMap,记住Map的Key,代码中需要通过这个Key进行操作不同redis服务器 -->
    <bean id="mutilJedisPoolMap" class="java.util.HashMap">
        <constructor-arg>
            <map>
                <entry key="xxjedisPool" value-ref="jedisPool_xx" />
                <entry key="yyjedisPool" value-ref="jedisPool_yy" />
            </map>
        </constructor-arg>
    </bean>

使用

    @Resource(name = "mutilJedisPoolMap")
    public Map<String, JedisPool> mutilJedisPoolMap;

    /**
     * 方法描述:从连接池获取jedis对象
     */
    public Jedis getResource(String redisPoolKey){
        logger.debug("[MutilJedisUtil:getResource]: get jedis Resource from Pool...");
        Jedis jedis = null;//声明jedis对象
//      int cycleTimes = 0;//出现异常已经循环获取的次数
        try{
            jedis = mutilJedisPoolMap.get(redisPoolKey).getResource();//从pool中获取jedis对象
            if(jedis == null){
                logger.error("[MutilJedisUtil:getResource]:get jedis object failed.message:n");
                return null;
            }
        }catch (JedisConnectionException ex) {
                logger.error("[MutilJedisUtil:getResource]:get jedis object failed.message:n"+ExceptionUtil.ExceptionToString(ex));
            }

        //获取对象如果不为空则返回
        if(jedis != null){
            logger.debug("[MutilJedisUtil:getResource]: get jedis Resource from Pool success.");
        }else{
            logger.error("[MutilJedisUtil:getResource]:get jedis object failed.if redis server is runing,please check the configration and Network connection.");
        }
        return jedis;
    }

    /**
     * 方法描述:使用完毕后将jedis对象归还连接池
     */
    public void returnResource(String redisPoolKey,Jedis jedis){
        try{
            if(jedis != null)
                this.mutilJedisPoolMap.get(redisPoolKey).returnResourceObject(jedis);//归还对象至pool
            logger.debug("[MutilJedisUtil:returnResource]: return jedis Resource to Pool  ...");
        }catch(JedisConnectionException ex){
            //归还失败,强制销毁该链接
            //this.jedisPool.returnResourceObject(jedis);//returnBrokenResource(jedis);
            logger.error("[MutilJedisUtil:returnResource]:" + ExceptionUtil.ExceptionToString(ex));
        }
    }
