使用Jedis在高并发报错 (java.net.SocketException: Connection reset by peer: socket write error)

onnection reset by peer: socket write error错误分析： 常出现的Connection reset by peer: 原因可能是多方面的，不过更常见的原因是： ①：服务器的并发连接数超过了其承载量，服务器会将其中一些连接Down掉； ②：客户关掉了浏览器，而服务器还在给客户端发送数据； ③：浏览器端按了Stop

1.报错信息资源网站：http://www.okeyl.com

java.lang.reflect.InvocationTargetException: null at sun.reflect.GeneratedMethodAccessor15.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) .... at java.lang.Thread.run(Unknown Source) Caused by: redis.clients.jedis.exceptions.JedisConnectionException: java.net.SocketException: Connection reset by peer: socket write error at redis.clients.jedis.Connection.flush(Connection.java:334) at redis.clients.jedis.Connection.getBinaryBulkReply(Connection.java:257) at redis.clients.jedis.BinaryJedis.get(BinaryJedis.java:244) ...... ... 15 common frames omitted Caused by: java.net.SocketException: Connection reset by peer: socket write error at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(Unknown Source) at java.net.SocketOutputStream.write(Unknown Source) at redis.clients.util.RedisOutputStream.flushBuffer(RedisOutputStream.java:52) at redis.clients.util.RedisOutputStream.flush(RedisOutputStream.java:216) at redis.clients.jedis.Connection.flush(Connection.java:331) ... 22 common frames omitted

所以本问题是由 ①造成的

2.修改之前的代码

初始化jedis的代码

/**
  * 在多线程环境同步初始化
  */
 private static synchronized void poolInit() { if (pool == null) { createJedisPool(); } } * 获取一个jedis 对象 * * @return */ public static Jedis getJedis() { if (pool == null) { poolInit(); } return pool.getResource(); }

使用jedis的代码

private static Jedis jedis = JedisPoolUtil.getJedis(); public static Object getObject(String key) { if(exists(key)){ return deserialize(jedis.get(key.getBytes())); } return null; }

3.修改之后的代码

初始化jedis的代码

/**
 * 获取一个jedis 对象
 *
 * @return
 */
public static Jedis getJedis() { if (pool == null) { poolInit(); } //如果没有以下代码会造成初始化的jedis拿不到 jedis对象 Jedis jedis = null; try { if (pool != null) { jedis = pool.getResource(); } } catch (Exception e) { logger.error("获取redis失败 : {}" + ExceptionUtils.getStackTrace(e)); } return jedis; }

使用jedis的代码

/**
    * 读取对象
    *
    * @param key
    * @return
    */
   public static Object getObject(String key) { if (exists(key)) { //初始化jedis用完之后关闭连接 Jedis jedis = JedisPoolUtil.getJedis(); Object object = deserialize(jedis.get(key.getBytes())); jedis.close(); return object; } return null; }
