創建db.properties文件

redis.host=bigdata-hpsk01.huadian.comredis.port=6379redis.maxIdle=10redis.minIdle=10redis.maxTotal=50

書寫工具類

package com.huadian.redisUntil;import redis.clients.jedis.Jedis;import redis.clients.jedis.JedisPool;import redis.clients.jedis.JedisPoolConfig;public final class JedisPoolUntil { private static String ADDR = '192.168.59.160'; //Redis的端口號 private static int PORT = 6379; /* //可用連接實例的最大數目，默認值為8； //如果賦值為-1，則表示不限制；如果pool已經分配了maxActive個jedis實例，則此時pool的狀態為exhausted(耗盡)。 private static int MAX_ACTIVE = 1024; //控制一個pool最多有多少個狀態為idle(空閑的)的jedis實例，默認值也是8。 private static int MAX_IDLE = 200; //等待可用連接的最大時間，單位毫秒，默認值為-1，表示永不超時。如果超過等待時間，則直接拋出JedisConnectionException； private static int MAX_WAIT = 10000; private static int TIMEOUT = 10000;*//* //在borrow一個jedis實例時，是否提前進行validate操作；如果為true，則得到的jedis實例均是可用的； private static boolean TEST_ON_BORROW = true;*/ private static int MAXTOTAL=20; private static int MINIDLE=10; private static int MAXIDLE=15; private static JedisPool jedisPool = null; /** * 初始化Redis連接池 */ static { try { JedisPoolConfig config = new JedisPoolConfig(); config.setMaxTotal(MAXTOTAL); config.setMaxIdle(MINIDLE); config.setMinIdle(MAXIDLE); jedisPool = new JedisPool(config, ADDR, PORT); } catch (Exception e) { e.printStackTrace(); } } /** * 獲取Jedis實例 * @return */ public synchronized static Jedis getJedis() { try { if (jedisPool != null) { Jedis resource = jedisPool.getResource(); return resource; } else { return null; } } catch (Exception e) { e.printStackTrace(); return null; } } /** * 釋放jedis資源 * @param jedis */ public static void returnResource(final Jedis jedis) { if (jedis != null) { jedisPool.returnResource(jedis); } }}

書寫測試類

package com.huadian.jedis;import com.huadian.redisUntil.JedisPoolUntil;import org.junit.Test;import redis.clients.jedis.Jedis;import redis.clients.jedis.JedisPool;import redis.clients.jedis.JedisPoolConfig;public class JedisDemo { private Jedis jedis = null; /** * 單連接 */ @Test public void jedisSingleConn(){ String host = '192.168.59.160'; int port = 6379; Jedis jedis = new Jedis(host, port); jedis.set('name','張三'); jedis.set('age','18'); String s = jedis.get('name'); String s1 = jedis.get('age'); System.out.println(s); System.out.println(s1); } /** * 連接池連接 */ @Test public void jedisPoolConn(){ JedisPoolConfig jedisPoolConfig = new JedisPoolConfig(); jedisPoolConfig.setMaxTotal(20); jedisPoolConfig.setMinIdle(10); jedisPoolConfig.setMaxIdle(15); JedisPool jedisPool = new JedisPool(jedisPoolConfig, '192.168.59.160', 6379); Jedis jedis = jedisPool.getResource(); //取數據 String s = jedis.get('name'); String s1 = jedis.get('age'); System.out.println(s); System.out.println(s1); } /** * 連接池連接 * 工具類 */ @Test public void jedisPoolConn1(){ Jedis jedis1 = JedisPoolUntil.getJedis(); //取數據 String s = jedis1.get('name'); String s1 = jedis1.get('age'); System.out.println(s); System.out.println(s1); }}

補充知識：JAVA使用Redis所需的MAVEN的POM文件

redis不僅可以通過命令行進行操作，同時redis也可以通過javaAPI進行操作,這是操作redis所需的依賴

<dependencies> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>6.14.3</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.0</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> <!-- <verbal>true</verbal>--> </configuration> </plugin> </plugins> </build>

以上這篇使用java連接Redis,Maven管理操作就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持好吧啦網。
