Redis单机、集群环境下配置及模板工具类

Redis服务器可以自行到官网上下载，使用时将其配置成系统服务即可。

自定义一个接口，对外提供Redis服务

package com.taotao.sso.dao;
public interface JedisClient {
String get(String key);
String set(String key, String value);
String hget(String hkey, String key);
long hset(String hkey, String key, String value);
long incr(String key);
long expire(String key, int second);
long ttl(String key);
long del(String key);
long hdel(String hkey, String key);
}

单机类与集群类分两个文件进行实现该接口，下面是集群类的实现方法

package com.taotao.sso.dao.impl;
import com.taotao.sso.dao.JedisClient;
import org.springframework.beans.factory.annotation.Autowired;
import redis.clients.jedis.JedisCluster;
public class JedisClientCluster implements JedisClient {

@Autowired
private JedisCluster jedisCluster;

@Override
public String get(String key) {
return jedisCluster.get(key);
}

@Override
public String set(String key, String value) {
return jedisCluster.set(key, value);
}

@Override
public String hget(String hkey, String key) {
return jedisCluster.hget(hkey, key);
}

@Override
public long hset(String hkey, String key, String value) {
return jedisCluster.hset(hkey, key, value);
}

@Override
public long incr(String key) {
return jedisCluster.incr(key);
}

@Override
public long expire(String key, int second) {
return jedisCluster.expire(key, second);
}

@Override
public long ttl(String key) {
return jedisCluster.ttl(key);
}

@Override
public long del(String key) {

return jedisCluster.del(key);
}

@Override
public long hdel(String hkey, String key) {

return jedisCluster.hdel(hkey, key);
}

}

下面是单机类的实现方法

package com.taotao.sso.dao.impl;
import org.springframework.beans.factory.annotation.Autowired;
import com.taotao.sso.dao.JedisClient;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
public class JedisClientSingle implements JedisClient{

@Autowired
private JedisPool jedisPool;

@Override
public String get(String key) {
Jedis jedis = jedisPool.getResource();
String string = jedis.get(key);
jedis.close();
return string;
}

@Override
public String set(String key, String value) {
Jedis jedis = jedisPool.getResource();
String string = jedis.set(key, value);
jedis.close();
return string;
}

@Override
public String hget(String hkey, String key) {
Jedis jedis = jedisPool.getResource();
String string = jedis.hget(hkey, key);
jedis.close();
return string;
}

@Override
public long hset(String hkey, String key, String value) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.hset(hkey, key, value);
jedis.close();
return result;
}

@Override
public long incr(String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.incr(key);
jedis.close();
return result;
}

@Override
public long expire(String key, int second) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.expire(key, second);
jedis.close();
return result;
}

@Override
public long ttl(String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.ttl(key);
jedis.close();
return result;
}

@Override
public long del(String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.del(key);
jedis.close();
return result;
}

@Override
public long hdel(String hkey, String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.hdel(hkey, key);
jedis.close();
return result;
}

}
