憋了很久的问题－java.net.SocketTimeoutException: Read timed out


【问题描述】请求一个webservice偶尔会返回异常，如下：

这个异常并不是每次都抛出，而是当对方的webservice响应时间超过约2秒的时候才会抛出，我的程序并没有设置超时，而在家中的调试环境去访问这个webservice这种异常无法重现，已经排除了网络问题以及编码上的问题。所以我考虑是操作系统或weblogic设置不当（我方程序的weblogic容器，因为我们weblogic处理的http请求也很多）所引起，请大家帮我看看是什么原因？不胜感激！！！

就是我在我们的weblogic中部署了一个war，这个war里面有一个类去请求另一个webservice，但是发现当对方返回响应的时候，有时我这边会抛出timeout异常，已经对网络进行抓包，发现我们产生异常的时候，对方的响应还没有发送完毕，我方主机就发送了断开连接的包。这个包我的程序肯定没有发，我怀疑是操作系统或者weblogic的原因。

我用的是weblogic server9.2 有时请求和响应正常，有时请求响应不正常；请求不正常的时候抓包表现为：大约两秒左右，对方的响应还没有发送完毕，我方主机就发送了断开连接的包。

主要是客户端没有在限定的时间内将数据发送的服务器，可以通过setSoTimeout(int timeout)来设置socket超时。

[天外流星]

在web.xml中加入HungServerRecoverSecs这个参数,时间为秒.设置时长大点.

[zhaoqiubo]

to 深男大盗：
1.程序没有限制超时。

2.HungServerRecoverSecs是配置代理的，跟我这个请求响应有什么关系吗？

[ray_1981]

在控制台把超时时间设置的大一点看看！

[zhaoqiubo]

根本就没有设置超时时间，我说了2秒主机就发中断包，我曾经尝试过设置超时为30秒。

我和你遇到的问题一模一样,不知道该如何解决....

[MavenTalk]

同样的问题，咋没有兄弟搞出个解决方案

[quqi99]

这是JDK的一个BUG，见SUN公司的BUG列表：http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4352956

[zygcs]

我也碰到了类似的情况。

检查了一下代码，
客户端发送时， out.print("XXXXX");

服务端接收时，in.readLine();

导到两边接收不一致。

后来客户端改为 out.println("XXXXX"); 服务端改为 in.readLine();

测试正常。
