我有两个运行 local 的应用程序，一个是JBoss，另一个是在tomcat上运行。 Jboss应用程序是遗留应用程序，我在其中进行了代码更改以将流量路由到tomcat服务器。我想在我们的QA盒上部署之前先在本地测试这个代码更改。如果请求是某种类型的JBoss应用程序构建HttpClient并使用适当的请求，标题等对tomcat应用程序进行POST调用，那么我已经打印了这个，所以这里没有问题。现在在我的tomcat应用程序的控制台日志中，我只看到SocketTimeoutException下面的错误，所以请求立即死在某处。我迷失在这里并且不知道如何进一步调试
我尝试过的事情 1.我多次重启应用程序 2.增加套接字超时和连接超时等 3.在调试模式下启动JBoss应用程序并确保在实际路由到tomcat之前发生请求，标头，http客户端配置等。

经过进一步调试后，我发现错误发生在context.proceed();行的tomcat服务器读取拦截器
public class DecoratedReaderInterceptor implements ReaderInterceptor {
@Override
public Object aroundReadFrom(ReaderInterceptorContext context) throws IOException {
boolean validate = shouldValidateResource(context);
Object obj = context.proceed();
if (obj instanceof Resource) {
processResource((Resource) obj, validate);
} else if (obj instanceof Resource[]) {
for (Resource resource : (Resource[]) obj) {
processResource(resource, validate);
}
}
return obj;
}
}
找到了答案，我感到尴尬。在JBoss服务器中，我添加了一个调试语句，用于读取流以输出请求，现在流已经被读取，tomcat服务器没有任何消耗。因此SocketTimeoutException
