Question

调用一个非常持久的远程EJB方法（> 30分钟）我得到了以下套接字超时异常：

查看上面的堆栈，很明显，通过套接字传输调用远程EJB的Jboss默认超时为30分钟（1800000毫秒）。我在网上阅读了很多主题，但我找不到有效的解决方案，甚至尝试使用RedHat官方解决方案（https://access.redhat.com/solutions/25149）。

经过一些Jboss内部调试（主要与JBoss Remoting模块有关）后，我提出了以下解决方案：

- ＆GT;定义（例如通过扩展）一个新的org.jboss.remoting.transport.socket.TransportClientFactory，用新的所需超时来实现ClientInvoker：

public final class TestSocketClientFactory extends TransportClientFactory {

    private static final String SOCKET_TIMEOUT_IN_MILLISECS = "7200000";// 2 hours (jboss default is 30 mins)

    @SuppressWarnings({ "unchecked", "rawtypes" })
    @Override
    public ClientInvoker createClientInvoker(InvokerLocator locator, Map config) throws IOException {
        config.put(SocketClientInvoker.SO_TIMEOUT_FLAG, SOCKET_TIMEOUT_IN_MILLISECS);
        return super.createClientInvoker(locator, config);
    }
}

- ＆GT;在org.jboss.remoting.InvokerRegistry中注册这个新工厂（例如在静态块中）：

static {
    InvokerRegistry.registerInvokerFactories("socket", TestSocketClientFactory.class, TransportServerFactory.class);
}

希望这会有所帮助！
