如何解决？

亲，根据您提供的错误信息我在网上百度了下大概可能如下四种原因：
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；

4：服务器给客户端响应结果给防火墙拦截了。
您根据这四种情况确认下。如有问题我们再沟通。谢谢

shary，你这样简单的baidu是不对的....
如果只是简单的百度”Connection reset by peer: socket write error“， 难道我不会么？

你仔细看看出错信息就会看到: at com.mysql.jdbc.MysqlIO.send(MysqlIO.java:3272)
这和数据库相关，和浏览器，客户端毫无关系。

跟客户沟通应该是mysql数据库版本的问题而引起的拿不到连接。目前客户在尝试升级到mysql最新版数据库
