使用codis的java端jodis时 ，看到proxy 的PooledObject 对象的定义为

  public PooledObject(String addr, JedisPool pool) {
            this.addr = addr;
            this.pool = pool;
        }

 而 jedis是直接使用了JedisPool，JedisPool有个returnResource的方法把连接放回连接池。

public class JedisPool extends Pool<Jedis> {
...
 @Deprecated
  public void returnResource(final Jedis resource) {
    if (resource != null) {
      try {
        resource.resetState();
        returnResourceObject(resource);
      } catch (Exception e) {
        returnBrokenResource(resource);
        throw new JedisException("Could not return the resource to the pool", e);
      }
    }
  }

 考虑PooledObject如何实现returnResource？ 上网找了以后发现，

 /**
  * The 2.6+ Jedis and the current Jodis have implemented the closeable
  * interface . Therefore, you don't need to use pool to call
  * returnResource() and you should invoke jedis.close() when you need to
  * release the resource.
  */

于是，

	@Override
	public void close() throws DataAccessException {
//		super.close();
		this.getNativeConnection().close();
	}
