org.springframework.remoting.RemoteAccessException: Could not access HTTP invoker remote service occurs when starting tasks from anbother thread
提问by Julia
I have spring application with JavaFX client, and I get this exception when ever come method is called which runs in another thread (for background tasks) - which is not the main JavaFx thread.
我有 JavaFX 客户端的 Spring 应用程序，当调用在另一个线程（用于后台任务）中运行的方法时，我会收到此异常 - 这不是主 JavaFx 线程。

The last change I made, and I suspect, a cause of this - because I need user info from HTTP session, in each service proxy , I am passing this httpInvokerRequestExecutor bean:
我所做的最后一次更改，我怀疑，这是一个原因 - 因为我需要来自 HTTP 会话的用户信息，在每个服务代理中，我正在传递这个 httpInvokerRequestExecutor bean：
<bean id="httpInvokerRequestExecuter" class="org.springframework.remoting.httpinvoker.CommonsHttpInvokerRequestExecutor" >
for example:
<bean id="testServiceProxy"
class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
<property name="serviceUrl" value="${remoteUrl}/service/test/TestService" />
<property name="serviceInterface"
value="common.service.test.TestService" />
<property name="httpInvokerRequestExecutor" ref="httpInvokerRequestExecuter" />
</bean>
With methods which run in main thread, this never seems to happen.
对于在主线程中运行的方法，这似乎永远不会发生。
All ideas on caused and possible solutions are very welcomed.
非常欢迎有关原因和可能解决方案的所有想法。

Inrease the read timeout for httpInvokerRequestExecuter. The default is a minute. You can either increase it or set to 0 which means it will never timeout (probably not a good idea but good for a test).
增加读取超时httpInvokerRequestExecuter。默认值为一分钟。您可以增加它或设置为 0，这意味着它永远不会超时（可能不是一个好主意，但对测试很有用）。
Bean definition to remove readTimeout (or set it to applicable amount):
删除 readTimeout 的 Bean 定义（或将其设置为适用的数量）：
<bean id="httpInvokerRequestExecuter" class="org.springframework.remoting.httpinvoker.CommonsHttpInvokerRequestExecuto??r" >
<property name="readTimeout" value="0" />
</bean>
