1，添加隊列
/**
* add list
*
* @param key
* @param member
*/
protected static long lpush(String key, String member) {
Jedis jedis = null;
try {
jedis = ConnectionManager.getConnection();
return jedis.lpush(key, member);
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
} finally {
try {
ConnectionManager.closeConnection(jedis);
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
// TODO Auto-generated catch block
}
}
return 0;
}
2，查詢隊列
/**
* 查詢隊列
* @param key
* @param start 開始位置
* @param end 結束位置
* @return
*/
protected static List<String> lrange(String key,int start,int end) {
Jedis jedis = null;
try {
jedis = ConnectionManager.getConnection();
List<String> ls=jedis.lrange(key, start, end);
return ls;
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
} finally {
try {
ConnectionManager.closeConnection(jedis);
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
// TODO Auto-generated catch block
}
}
return null;
}
3，移除最先插入到隊列的值
/**
* 移除最先插入到隊列的值
* @param key
* @return 被移除的值
*/
protected static String rpop(String key) {
Jedis jedis = null;
try {
jedis = ConnectionManager.getConnection();
return jedis.rpop(key);
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
} finally {
try {
ConnectionManager.closeConnection(jedis);
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
// TODO Auto-generated catch block
}
}
return null;
}
4，獲取隊列長度
/**
* 獲取隊列長度
*
* @param key
* @param member
*/
protected static long llen(String key) {
Jedis jedis = null;
try {
jedis = ConnectionManager.getConnection();
Long l=jedis.llen(key);
return l;
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
} finally {
try {
ConnectionManager.closeConnection(jedis);
} catch (Exception e) {
logger.info("redis bug:" + e.getMessage());
// TODO Auto-generated catch block
}
}
return 0;
}
