redis3.0.7连接 <java>

来源：互联网发布：淘宝水果属于什么类目编辑：程序博客网时间：2024/06/05 22:44

1、关闭linux系统的防火墙

2.maven pom.xml文件

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.4.2</version>
</dependency>

<一>普通连接

package com.test;

import java.util.Iterator;
import java.util.Set;

import redis.clients.jedis.Jedis;

public class Test {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Jedis redis = new Jedis ("192.168.240.130",6379);//连接redis
Set keys = redis.keys("*");//列出所有的key，查找特定的key如：redis.keys("foo")
Iterator t1=keys.iterator() ;
while(t1.hasNext()){
Object obj1=t1.next();
System.out.println(obj1);
}
redis.disconnect(); //释放链接
}

}

<二>池链接

reids.properties文件

#最大分配对象的监测数
redis.pool.maxActive=1024
#最大能够保持idel状态的对象数
redis.pool.maxIdle=200
#当池内没有返回对象时，最大等待时间
redis.pool.maxWait=1000
#当调用borrow Object方法时，是否进行有效性检查
redis.pool.testOnBorrow=true
#当调用return Object方法时，是否进行有效性检查
redis.pool.testOnReturn=true
#IP
redis.ip=192.168.240.130
#Port
redis.port=6379

package com.test;

import java.util.Iterator;
import java.util.ResourceBundle;
import java.util.Set;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

public class RedisAPI {
private static JedisPool pool;
public static JedisPool getPool() {
ResourceBundle bundle = ResourceBundle.getBundle("redis");
if (bundle == null) {
throw new IllegalArgumentException(
"[redis.properties] is not found!");
}
if(pool == null){
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxTotal(Integer.valueOf(bundle
.getString("redis.pool.maxActive")));
config.setMaxIdle(Integer.valueOf(bundle
.getString("redis.pool.maxIdle")));
config.setMaxWaitMillis(Long.valueOf(bundle.getString("redis.pool.maxWait")));
config.setTestOnBorrow(Boolean.valueOf(bundle
.getString("redis.pool.testOnBorrow")));
config.setTestOnReturn(Boolean.valueOf(bundle
.getString("redis.pool.testOnReturn")));
pool = new JedisPool(config, bundle.getString("redis.ip"),
Integer.valueOf(bundle.getString("redis.port")));
}
return pool;
}
/**
* 返还到连接池
*
* @param pool
* @param redis
*/
public static void returnResource(JedisPool pool, Jedis redis) {
if (redis != null) {
pool.returnResource(redis);
}
}

/**

* @return
*/
public static String get(String key){
String value = null;

JedisPool pool = null;
Jedis jedis = null;
try {
pool = getPool();
jedis = pool.getResource();
value = jedis.get(key);
} catch (Exception e) {
//释放redis对象
pool.returnBrokenResource(jedis);
e.printStackTrace();
} finally {
//返还到连接池
returnResource(pool, jedis);
}

return value;
}

public static void main(String[] args) {
// TODO Auto-generated method stub

//释放redis对象
pool.returnBrokenResource(jedis);

} finally {
//返还到连接池
returnResource(pool, jedis);
}

}
