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：

POM：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.yzl</groupId>
  <artifactId>redis.first</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.9</version>
      <scope>test</scope>
    </dependency>
    
    <dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>2.7.1</version>
    </dependency>
    
    <dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>1.2.17</version>
    </dependency>
  </dependencies>
</project>

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
