Java operations on redis simple Jedis instances

Package com. weixuan. utils; import redis. clients. jedis. jedis;/*** Create by fengtang * 2015/7/30 * JavaRedis */public final class JedisUtils {/*** Create a jedis link. ** @ return returns the currently created redis link object */public static Jedis getJedisConnection () {Jedis jedis = new Jedis ("localhost", 6379); return jedis ;}} // test package com. weixuan. test; import com. weixuan. utils. jedisPoolUtils; import com. weixuan. utils. jedisUtils; import org. junit. test; import redis. clients. jedis. jedis; import redis. clients. jedis. jedisPool;/*** Create by fengtang * 2015/7/30 * JavaRedis */public class JedisTest {@ Test public void testJedisUtils () {System. out. println ("testJedisUtils" + JedisUtils. getJedisConnection ());}}

Simple JedisPool Application

** Note: the Jedis version is 2.1, and the common pool version is 1.5.
In later versions, some parameters are set differently, such as setMaxActive **

Package com. weixuan. utils; import redis. clients. jedis. jedisPool; import redis. clients. jedis. jedisPoolConfig; import java. util. resourceBundle;/*** Create by fengtang * 2015/7/30 * JavaRedis */public class JedisPoolUtils {public static JedisPool pool; static {ResourceBundle bundle = ResourceBundle. getBundle ("jedis"); JedisPoolConfig config = new JedisPoolConfig (); if (bundle = null) {throw new Ille GalArgumentException ("[jedis. properties] is not found! ");} Config. setMaxActive (Integer. valueOf (bundle. getString ("redis. pool. maxActive "); config. setMaxIdle (Integer. valueOf (bundle. getString ("redis. pool. maxIdle "); 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 ");} public static JedisPool getPool () {return pool ;}// test package com. weixuan. test; import com. weixuan. utils. jedisPoolUtils; import com. weixuan. utils. jedisUtils; import org. junit. test; import redis. clients. jedis. jedis; import redis. clients. jedis. jedisPool;/*** Create by fengtang * 2015/7/30 * JavaRedis */public class JedisTest {@ Test public void testJedisPoolUtils () throws Exception {JedisPool = JedisPoolUtils. getPool (); System. out. println ("testJedisPoolUtils --- pool ------------" + pool); Jedis jedis = pool. getResource (); System. out. println ("testJedisPoolUtils --- jedis ------------" + jedis );}}

Test in a later version

* Jedis version 2.7 common pool version 2.4 *

Set config. setMaxActive (Integer. valueOf (bundle. getString ("redis. pool. maxActive "); change to config. setMaxTotal (Integer. valueOf (bundle. getString ("redis. pool. maxTotal "); the configuration file also needs to be modified.

Easy to use

    package com.weixuan.redis;    import com.weixuan.utils.JedisPoolUtils;    import redis.clients.jedis.Jedis;    /**     * Create by fengtang     * 2015/7/30     * JavaRedis3     */    public class Main {    private Jedis jedis = JedisPoolUtils.getPool().getResource();    public void testInsert() {        jedis.set("testKey1", "testValue1");        jedis.set("testKey2", "testValue2");        jedis.set("testKey3", "testValue3");        jedis.set("testKey4", "testValue4");        jedis.set("testKey5", "testValue5");        jedis.set("testKey6", "testValue6");        jedis.set("testKey7", "testValue7");        jedis.set("testKey8", "testValue8");        jedis.set("testKey9", "testValue9");        jedis.set("testKey0", "testValue0");    }    public String testGet(String keyName) {        return jedis.get(keyName);    }    public static void main(String[] args) {        //new Main().testInsert();        System.out.println(new Main().testGet("testKey0"));    }}
