redis的使用方式方法有很多,我这里只用了这一种
redis.clients jedis 2.5.2
org.apache.commons commons-pool2 2.9.0
实现了两个方法,一个有返回值一个没有返回值,可以自定义实现方法
下面都自动关闭了连接,也可以不设置关闭,如果不关闭连接的话连接池会自动关闭连接 设置超时时间
@Lazy(value = true)
@Component
public class RedisClient {
private Logger log = LoggerFactory.getLogger(RedisClient.class);
@Resource
private JedisPool jedisPool;
public T use(Function function) {
Jedis jedis = jedisPool.getResource();
try{
T t = function.apply(jedis);
return t;
}catch (Exception e){
log.error(e.getMessage(),e);
}finally {
jedis.close();
}
return null;
}
public void voidUse(Consumer function) {
Jedis jedis = jedisPool.getResource();
try {
function.accept(jedis);
}catch (Exception e){
log.error(e.getMessage(),e);
}finally {
jedis.close();
}
}
public void setStringVal(String key,String val){
this.voidUse(e->{
e.set(key, val);
});
}
public String setStringValRet(String key,String val){
return this.use(e->{
return e.set(key, val);
});
}
public String getStringVal(String key){
return this.use(e->{
return e.get(key);
});
}
/**

//hmset
public String hmSetByMap(String key, Map map){
return this.use(e->{
return e.hmset(key,map);
});
}
public String hmSet(String key, String field,String val){
return this.use(e->{
Map map = new HashMap<>();
map.put(field,val);
return e.hmset(key,map);
});
}
//hgetall
public Map hGetAll(String key){
return this.use(e->{
return e.hgetAll(key);
});
}
//hdel
public Long hDel(String key,String ...field){
return this.use(e->{
return e.hdel(key,field);
});
}
//hexists
public Boolean hexists(String key,String field){
return this.use(e->{
return e.hexists(key,field);
});
}
//expire
public long expire(String key,int time){
return this.use(e->{
return e.expire(key,time);
});
}
//keys
public Set keys(String pattern){
return this.use(e->{
return e.keys(pattern);

}
//del
public long del(String key){
return this.use(e->{

});
}
public long del(String ...key){
return this.use(e->{
return e.del(key);
});
}
}
@Resource
private RedisClient redisClient;
//删除
public boolean deleteByUserCode(String key) {
long count = redisClient.hDel(WHITE_KEY_LIST,key);
return count>0;
}
//保存
public boolean save(String account,String userCode) {
String ret = redisClient.hmSet(WHITE_KEY_LIST,userCode,account);
return "OK".equals(ret);
}
其他方法可以自定义使用,有问题和建议请留言
