com.alibaba.dubbo.rpc.RpcException: Failed to invoke the method
查看了网友们的错误原因，
- 需要进行实例化的类没有进行实例化，具体没有实例化的类会在错误信息中显示，在错误信息中搜索“Serializable”即可找到将其实现序列化可消除错误。
- 是在使用Dubbo提供服务是在主机上启动了虚拟机的网络，在Windows中具体可以，在运行中输入“CMD”在CMD窗口中输入"ifconfig"命令查看，如果有其他除本地的网络链接，通过命令或者将其手动禁止，再启动Dubbo服务可以解决问题。
- 防火墙对应端口没有开启
我这里都不是因为这些导致的。

我出错原因有点与众不同，呵呵，竟是因为看到警告就加了句context.close();
1 public static void main(String[] args) { 2 try { 3 ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring/spring-context.xml"); 4 context.start(); 5 // context.close(); // 出错根源 6 } catch (Exception e) { 7 log.error("== DubboProvider context start error:",e); 8 } 9 synchronized (DubboProvider.class) { 10 while (true) { 11 try { 12 DubboProvider.class.wait(); 13 } catch (InterruptedException e) { 14 log.error("== synchronized error:",e); 15 } 16 } 17 } 18 }
