上一篇笔记Reddis集成，操作Redis使用的是RedisTemplate，但实际中还是有一大部分人习惯使用JedisPool和Jedis来操作Redis, 下面使用Jedis集成示例。

修改RedisConfig类如下：

[java] view plain copy

package com.vic.config;
import org.apache.log4j.Logger;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
/**
*
* @author vic
* @desc redis config bean
*
*/
@Configuration
@EnableAutoConfiguration
@ConfigurationProperties(prefix = "spring.redis", locations = "classpath:application.properties")
public class RedisConfig {
private static Logger logger = Logger.getLogger(RedisConfig.class);
private String hostName;
private int port;
private String password;
private int timeout;
@Bean
public JedisPoolConfig getRedisConfig(){
JedisPoolConfig config = new JedisPoolConfig();
return config;
}
@Bean
public JedisPool getJedisPool(){
JedisPoolConfig config = getRedisConfig();
JedisPool pool = new JedisPool(config,hostName,port,timeout,password);
logger.info("init JredisPool ...");
return pool;
}
public String getHostName() {
return hostName;
}
public void setHostName(String hostName) {
this.hostName = hostName;
}
public int getPort() {
return port;
}
public void setPort(int port) {
this.port = port;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getTimeout() {
return timeout;
}
public void setTimeout(int timeout) {
this.timeout = timeout;
}
}

因为JedisPool实例化对象，是将host,password等参数通过构造传入，所以在这里将整个RedisConfig定义为一个配置类，定义host,password等配置属性，通过spring boot属性文件自动注入。

接下来看看Service中如何使用：

修改IRedisService接口：

[java] view plain copy

RedisService实现类代码：

[java] view plain copy

package com.vic.service.impl;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.vic.service.IRedisService;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
/**
*
* @author vic
* @desc resdis service
*
*/
@Service
public class RedisServiceImpl implements IRedisService {
private static Logger logger = Logger.getLogger(RedisServiceImpl.class);
@Autowired
private JedisPool jedisPool;
@Override
public Jedis getResource() {
return jedisPool.getResource();
}
@SuppressWarnings("deprecation")
@Override
public void returnResource(Jedis jedis) {
if(jedis != null){
jedisPool.returnResourceObject(jedis);
}
}
@Override
public void set(String key, String value) {
Jedis jedis=null;
try{
jedis = getResource();
jedis.set(key, value);
logger.info("Redis set success - " + key + ", value:" + value);
} catch (Exception e) {
e.printStackTrace();
logger.error("Redis set error: "+ e.getMessage() +" - " + key + ", value:" + value);
}finally{
returnResource(jedis);
}
}
@Override
public String get(String key) {
String result = null;
Jedis jedis=null;
try{
jedis = getResource();
result = jedis.get(key);
logger.info("Redis get success - " + key + ", value:" + result);
} catch (Exception e) {
e.printStackTrace();
logger.error("Redis set error: "+ e.getMessage() +" - " + key + ", value:" + result);
}finally{
returnResource(jedis);
}
return result;
}
}

JedisPool对象使用自动注入，手动获取Jedis对象进行Redis操作，ExampleController进行测试：

[java] view plain copy

测试URL：http://localhost:8080/redis/set?value=vic 响应结果:

{"code":200,"success":true,"message":"success","response":null}

测试URL：http://localhost:8080/redis/get 响应结果:

{"code":200,"success":true,"message":"success","response":"vic"}
