1、关于spring配置文件中对于redis的配置
<!-- redis配置 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<!-- <property name="maxActive" value="90"/> -->
<property name="maxIdle" value="5"/>
<!-- <property name="maxWait" value="1000"/> -->
<property name="testOnBorrow" value="true"/>
</bean>
<!--配置redis数据源-->
<bean id="jedisPool" class="redis.clients.jedis.JedisPool" destroy-method="destroy">
<constructor-arg ref="jedisPoolConfig"/>
<constructor-arg value="192.168.21.195"/>
<constructor-arg value="6379"/>
</bean>
<!--配置自定义的RedisAPI工具类-->
<bean id="redisAPI" class="org.slsale.common.RedisAPI">
<property name="jedisPool" ref="jedisPool"/>
</bean>
2、配置自定义的RedisAPI,对redis数据库的管理
package org.slsale.common;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
/**
* jedisAPI
* @author luzhewu
*
*/
public class RedisAPI {
public JedisPool jedisPool;// redis连接池对象
public JedisPool getJedisPool() {
return jedisPool;
}
public void setJedisPool(JedisPool jedisPool) {
this.jedisPool = jedisPool;
}
/**
* set key and value tp redis
* @param key
* @param value
* @return
*/
public boolean set(String key, String value) {
Jedis jedis = null;
try {
jedis = jedisPool.getResource();// 获取jedis对象
jedis.set(key, value);
return true;
} catch (Exception e) {
e.printStackTrace();
} finally {
// 返还到连接池
returnResource(jedisPool, jedis);
}
return false;
}
/**
* 判断某个key是否存在
* @param key
* @return
*/
public boolean exist(String key) {
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
return jedis.exists(key);
} catch (Exception e) {
e.printStackTrace();
} finally {
// 返还到连接池
returnResource(jedisPool, jedis);
}
return false;
}
/**
* 通过key获取value
* @param key
* @return
*/
public String get(String key) {
String value = null;
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
value = jedis.get(key);
} catch (Exception e) {
e.printStackTrace();
} finally {
// 返还到连接池
returnResource(jedisPool, jedis);
}
return value;
}
/**
* 返还到连接池
* @param jedisPool
* @param jedis
*/
public static void returnResource(JedisPool jedisPool, Jedis jedis) {
if (jedis != null) {
jedisPool.returnResource(jedis);
}
}
}
3、redis相关依赖
<!-- redis相关依赖jedis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.6.1</version>
