Redis的客户端实现-Jedis
来源：互联网 发布：长得漂亮知乎 编辑：程序博客网 时间：2024/05/16 19:45
Redis的中文官方网站：http://www.redis.cn/
目前Redis大概有4中基于Java语言的Client，分别是Jredis，Jedis，JDBC-Redis ,RJC，这里只说Jedis，因为它是官方推荐的客户端。
一、简单使用Jedis
（1）maven配置：
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.1.0</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
（2）简单测试
Jedis jedis = new Jedis("localhost");
jedis.set("foo","bar");
String value = jedis.get("foo");
二、池化使用Jedis
Jedis使用commons-pool完成池化实现。
①redisConfig.properties文件配置如下：
#redis服务器IP
redis.ip=192.168.1.74
#redis服务Port
redis.port=6379
#最大分配的对象数
redis.pool.maxActive=1024
#最大能够保持idel状态的对象数
redis.pool.maxIdle=200
#当池内没有返回对象时，最大等待时间
redis.pool.maxWait=1000
#当调用borrow Object方法时，是否进行有效性检查
redis.pool.testOnBorrow=true
#当调用return Object方法时，是否进行有效性检查
redis.pool.testOnReturn=true
②在静态代码段中完成初始化
private static JedisPool pool = null;
static{
ResourceBundle bundle = ResourceBundle.getBundle("redisConfig");
if (bundle == null) {
throw new IllegalArgumentException("[redisConfig.properties] is not found!");
}
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxActive(Integer.valueOf(bundle.getString("redis.pool.maxActive")));
config.setMaxIdle(Integer.valueOf(bundle.getString("redis.pool.maxIdle")));
config.setMaxWait(Long.valueOf(bundle.getString("redis.pool.maxWait")));
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")));
}
③通过从pool中获取jedis操作Redis
// 从池中获取一个Jedis对象
Jedis jedis = pool.getResource();
④使用后一定要释放Jedis对象
// 释放对象池
pool.returnResource(jedis);
三、Jedis工具类封装
数据类型暂且包括字符串（String）、 列表（list）、有序集合（sorted sets）
