org.springframework.remoting.RemoteAccessException：从另一个线程启动任务时，无法访问HTTP调用程序远程服务

Question

我有JavaFX客户端的弹簧应用程序，并且我得到此异常时，它会在另一个线程中运行时调用方法用于后台任务） - 这不是主要的JavaFx线程。

我的最后一次更改，我怀疑，这样一个原因 - 因为我需要从HTTP会话用户信息，在每个服务代理，我通过这个httpInvokerRequestExecutor豆：

<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> 

使用在主线程中运行的方法，这似乎永远不会发生。

所有关于引起的和可能的解决方案的想法都非常受欢迎。

提高httpInvokerRequestExecuter的读取超时时间。默认值是一分钟。你可以增加它，也可以设置为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定义删除readTimeout（或将其设置为可申请数量）：

<bean id="httpInvokerRequestExecuter" class="org.springframework.remoting.httpinvoker.CommonsHttpInvokerRequestExecuto‌​r" > 
    <property name="readTimeout" value="0" /> 
</bean>
