redis在java中的客户端连接

单例模式下创建连接池，包括断线重连等机制。

public class RedisClient {

private static JedisPool pool = null; 
private RedisClient(){

initial();
}
private static RedisClient client = new RedisClient();
public static RedisClient getClient(){
return client;
}

private void initial() {
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxActive(30000);
jedisPoolConfig.setMaxIdle(600);
jedisPoolConfig.setMaxWait(1000);
jedisPoolConfig.setTestOnBorrow(true);
if (pool == null) { 
try {
pool = new JedisPool(jedisPoolConfig, "10.0.201.140", 5379,4000000);
} catch (Exception e) {
e.printStackTrace();
pool.destroy();
initial();//断线重连
} 
} 
} 
/**
* 获取redis连接的 Pipelined
* @return
*/
public synchronized jedis getJedis() { 
Jedis jd = null;
try {
jd= pool.getResource();
} catch (Exception e) {
if(jd!=null){
pool.returnBrokenResource(jd);
}
e.printStackTrace();
jd = getJedis();//递归进行断线重连
} 
return jd;
} 
/** 
* 释放被损坏的jedis. 
* 
* @param jd 
*/ 
public synchronized void releaseBrokenJedis(Jedis jd) { 
pool.returnBrokenResource(jd); 
jd = null; 
} 

/** 
* 从连接池中释放jedis 
* 
* @param jd 
*/ 
public synchronized void releaseJedis(Jedis jd) { 
pool.returnResource(jd); 
jd = null; 
} 
}
