3、redis之java client环境搭建

JAVA Client环境搭建

POM:

<dependency>
  <groupId>redis.clients</groupId>
  <artifactId>jedis</artifactId>
  <version>2.7.1</version>
</dependency>

非maven的可以去官网直接下载jar包

如果需要使用池需要用到common-pool,上面那个jedis的POM里已经包含了common-pool2-2.3.jar了,不需要再进行单独引用

common-pool2的POM:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.3</version>
</dependency>

 建立MAVEN项目

目录结构如下:

RedisApp.java

package com.yzl;

import org.apache.log4j.Logger; import redis.clients.jedis.Jedis; /** * Reids之jedis的CRUD操作 * * @author yangzhilong * @see [相关类/方法](可选) * @since [产品/模块版本] (可选) */ public class RedisApp { public Logger log = Logger.getLogger(this.getClass()); /** * * 功能描述: <br> * CRUD操作之hello world * * @see [相关类/方法](可选) * @since [产品/模块版本](可选) */ public void crudFromRedisWidthSimple(){ Jedis jedis = new Jedis("127.0.0.1", 6379); log.info("insert value to redis~~~"); jedis.set("name", "hello jedis"); log.info("get value from redis, value:" + jedis.get("name")); log.info("delete key from redis~~~"); jedis.del("name"); log.info("get value from redis, value:" + jedis.get("name")); jedis.close(); } }

RedisAppTest.java

package com.yzl;

import org.junit.Test; /** * RedisApp的测试类 * * @author yangzhilong * @see [相关类/方法](可选) * @since [产品/模块版本] (可选) */ public class RedisAppTest { @Test public void crudFromRedisWidthSimpleTest(){ RedisApp app = new RedisApp(); app.crudFromRedisWidthSimple(); } }

log4j.properties

### set log levels ###
log4j.rootLogger = debug , stdout ### \u8F93\u51FA\u5230\u63A7\u5236\u53F0 ### log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target = System.out log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss,SSS} [%c]-[%p] %m%n

运行测试用例的结果:

2015-08-12 13:57:34,261 [com.yzl.RedisApp]-[INFO] insert value to redis~~~
2015-08-12 13:57:34,276 [com.yzl.RedisApp]-[INFO] get value from redis, value:hello jedis
2015-08-12 13:57:34,276 [com.yzl.RedisApp]-[INFO] delete key from redis~~~
2015-08-12 13:57:34,276 [com.yzl.RedisApp]-[INFO] get value from redis, value:null
