Java操作Redis

目前Jedis是官方推荐的比较好的Redis操作API包，我们这里结合Spring来看下如何使用Redis这一神器。

1、在pom文件中引入jredis包：

<dependency>
  <groupId>redis.clients</groupId>
  <artifactId>jedis</artifactId>
  <version>2.8.1</version>
</dependency>

2、在Spring的resource目录中增加Redis的配置文件/src/main/resources/redis.properties

# Redis settings
redis.host=192.168.56.101
redis.port=6379
redis.pass=lxh20160330
redis.timeout=0

redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true

3、在Spring的配置文件中配置好Redis的相关Bean注入：

1 <?xml version="1.0" encoding="UTF-8"?>  
 2 <beans xmlns="http://www.springframework.org/schema/beans"  
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"  
 4     xmlns:context="http://www.springframework.org/schema/context"  
 5     xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"  
 6     xmlns:aop="http://www.springframework.org/schema/aop"  
 7     xsi:schemaLocation="  
 8             http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
 9             http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">  
10 
11     <context:property-placeholder location="classpath:redis.properties" />  
12     <context:component-scan base-package="com.redis.demo" />
13     
14     <bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" />
15     
16     <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
17         <property name="maxActive" value="50" />
18         <property name="maxIdle" value="8" />
19         <property name="maxWait" value="1000" />
20         <property name="testOnBorrow" value="true"/>
21         <property name="testOnReturn" value="true"/>
22         <!-- <property name="testWhileIdle" value="true"/> -->
23     </bean>
24 
25     <bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool"  scope="singleton">
26         <constructor-arg index="0" ref="jedisPoolConfig" />
27         <constructor-arg index="1">
28             <list>
29                 <bean class="redis.clients.jedis.JedisShardInfo">
30                     <constructor-arg name="host" value="${redis.host}" />
31                     <constructor-arg name="port" value="${redis.port}" />
32                     <constructor-arg name="timeout" value="${redis.timeout}" />
33                     <constructor-arg name="weight" value="1" />
34                 </bean>
35             </list>
36         </constructor-arg>
37     </bean>
38 </beans>

4、获取Redis客户端对象的类

package com.redis.demo.service.impl;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.redis.demo.service.RedisService;

import redis.clients.jedis.ShardedJedis;
import redis.clients.jedis.ShardedJedisPool;

@Repository("redisService")
public class RedisServiceImpl implements RedisService {
     private static final Logger log = LoggerFactory.getLogger(RedisServiceImpl.class);

    @Autowired
    private ShardedJedisPool shardedJedisPool;
 
     public ShardedJedis getRedisClient() {
         try {
            ShardedJedis shardJedis = shardedJedisPool.getResource();
             return shardJedis;
         } catch (Exception e) {
             log.error("getRedisClent error", e);
         }
         return null;
    }
 
     public void returnResource(ShardedJedis shardedJedis) {
         shardedJedisPool.returnResource(shardedJedis);
     }
 
     public void returnResource(ShardedJedis shardedJedis, boolean broken) {
         if (broken) {
             shardedJedisPool.returnBrokenResource(shardedJedis);
         } else {
             shardedJedisPool.returnResource(shardedJedis);
         }
     }
 }

5、RedisClient类中实现Redis的相关操作

  package com.redis.demo;
    
    import java.util.Collection;
    import java.util.List;
    import java.util.Map;
    import java.util.Set;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
   import org.springframework.beans.factory.annotation.Autowired;
   
   import com.redis.demo.service.impl.RedisServiceImpl;
   
   import redis.clients.jedis.BinaryClient.LIST_POSITION;
   import redis.clients.jedis.Jedis;
   import redis.clients.jedis.JedisShardInfo;
   import redis.clients.jedis.ShardedJedis;
   import redis.clients.jedis.ShardedJedisPipeline;
   import redis.clients.jedis.SortingParams;
   import redis.clients.jedis.Tuple;
   

   public class RedisClient {
   
       private static final Logger log = LoggerFactory.getLogger(RedisClient.class);
   
       @Autowired
       private RedisServiceImpl redisService;
   
       public void disconnect() {
           ShardedJedis shardedJedis = redisService.getRedisClient();
           shardedJedis.disconnect();
       }
   
       /**
        * 设置单个值
        */
       public String set(String key, String value) {
           String result = null;
   
           ShardedJedis shardedJedis = redisService.getRedisClient();
           if (shardedJedis == null) {
               return result;
           }
           boolean flag = false;
           try {
               result = shardedJedis.set(key, value);
           } catch (Exception e) {
               log.error(e.getMessage(), e);
               flag = true;
           } finally {
               redisService.returnResource(shardedJedis, flag);
           }
           return result;
       }
   
       /**

           }
   
           boolean flag = false;
           try {

           } catch (Exception e) {

               flag = true;
           } finally {
