RedisClient类中实现Redis的相关操作

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：

  redis.clients
  jedis
  2.8.1

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. 1

2. 2

3. 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

4. 4 xmlns:context="http://www.springframework.org/schema/context"

5. 5 xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"

6. 6 xmlns:aop="http://www.springframework.org/schema/aop"

7. 7 xsi:schemaLocation="

8. 8 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

9. 9 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

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);
         }
     }
 }
