java操作redis，javaredis

java操作redis，javaredis
Java操作redis簡單的Jedis執行個體

package com.weixuan.utils;import redis.clients.jedis.Jedis;/** * Create by fengtang * 2015/7/30 * JavaRedis */public final class JedisUtils {    /**     * 建立一個jedis連結.     *     * @return 返回當前建立的redis連結化物件     */    public static Jedis getJedisConnection() {        Jedis jedis = new Jedis("localhost", 6379);        return jedis;    }}//測試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());    }}

簡單的JedisPool應用

**注意，版本Jedis版本是2.1 ，common pool 的版本是1.5
高版本中有些參數的設定不一樣，比如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 IllegalArgumentException("[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;    }}//測試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 pool = JedisPoolUtils.getPool();        System.out.println("testJedisPoolUtils ---pool ------------" + pool);        Jedis jedis = pool.getResource();        System.out.println("testJedisPoolUtils --- jedis ------------" + jedis);    }}

高版本中測試

* Jedis 版本2.7 common pool 版本2.4*

    將    config.setMaxActive(Integer.valueOf(bundle.getString("redis.pool.maxActive")));    換成    config.setMaxTotal(Integer.valueOf(bundle.getString("redis.pool.maxTotal")));    設定檔也需要改

簡單的使用

    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"));    }}
