com.alibaba.dubbo.rpc.RpcException: Failed to invoke the method

查看了网友们的错误原因，

1. 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。
2. 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。
3. 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     }
