spring redisTemplate 配置

 redis的官网(http://www.redis.io/)

      

     编辑pom.xml

如果没有使用maven,那直接下载jar包http://s3.amazonaws.com/dist.springframework.org/release/DATAKV/spring-data-redis-1.0.0.RELEASE.zip

 

   在spring配置文件里添加

 

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="localhost"/>
        <property name="port" value="6636"/>
</bean>

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory"/>
</bean>

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="localhost"/>
        <property name="port" value="6636"/>
</bean>

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory"/>
</bean>

 

    那就可以直接用redisTemplate，redisTemplate和HibernateTemplate很相似。

 

@Service
public class RedisService {
    @Resource
    private RedisTemplate<Serializable, Serializable> template;

 /**
     * 向redis里面添加key-value格式的数据
     *
     * @param key   key
     * @param value value
     */

    public void set(final Serializable key, final Serializable value) {
        template.execute(new RedisCallback<Object>() {
            @Override
            public Object doInRedis(RedisConnection connection) throws DataAccessException {
                byte[] key_ = RedisUtil.getBytesFromObject(key);
                byte[] value_ = RedisUtil.getBytesFromObject(value);
                connection.set(key_, value_);
                return true;
            }
        });
    }

 /**
     * 根据key从redis里面取出value
     *
     * @param key   key
     */
 public Serializable get(final Serializable key) {
        return template.execute(new RedisCallback<Serializable>() {
            @Override
            public Serializable doInRedis(RedisConnection connection) throws DataAccessException {

                byte[] keyBytes = RedisUtil.getBytesFromObject(key);
                byte[] bytes = connection.get(keyBytes);
                return (Serializable) RedisUtil.getObjectFromBytes(bytes);
            }
        });
    }
}

@Service
public class RedisService {
    @Resource
    private RedisTemplate<Serializable, Serializable> template;

 /**
     * 向redis里面添加key-value格式的数据
     *
     * @param key   key
     * @param value value
     */

    public void set(final Serializable key, final Serializable value) {
        template.execute(new RedisCallback<Object>() {
            @Override
            public Object doInRedis(RedisConnection connection) throws DataAccessException {
                byte[] key_ = RedisUtil.getBytesFromObject(key);
                byte[] value_ = RedisUtil.getBytesFromObject(value);
                connection.set(key_, value_);
                return true;
            }
        });
    }

 /**
     * 根据key从redis里面取出value
     *
     * @param key   key
     */
 public Serializable get(final Serializable key) {
        return template.execute(new RedisCallback<Serializable>() {
            @Override
            public Serializable doInRedis(RedisConnection connection) throws DataAccessException {

                byte[] keyBytes = RedisUtil.getBytesFromObject(key);
                byte[] bytes = connection.get(keyBytes);
                return (Serializable) RedisUtil.getObjectFromBytes(bytes);
            }
        });
    }
}

   

     看了一点JedisConnectionFactory，之际上它只是对Jedis做了下简单了封装，再加上自己的连接池实现。
