在dubbo配置文件中

dubbo.container=log4j,spring
dubbo.application.name=web
dubbo.application.owner=ipharmacare
#dubbo.registry.address=multicast://224.5.6.7:1234
dubbo.registry.address=zookeeper\://10.1.2.37\:2181  // 由于修改了代码  并没有提交上去,所以该地址指向的是主机,而不是本地.当web调用我在注册中心写的方法时,肯定出错.
dubbo.protocol.name=dubbo
dubbo.protocol.port=38889
dubbo.consumer.timeout=300000
#dubbo.registry.address=redis://127.0.0.1:6379
#dubbo.registry.address=dubbo://127.0.0.1:9090
#dubbo.consumer.timeout=2
dubbo.log4j.file=logs/yb-web.log
dubbo.log4j.level=WARN
noPermUrl=

解决方案: 将

dubbo.registry.address=zookeeper\://10.1.2.37\:2181

改为

dubbo.registry.address=zookeeper\://127.0.0.1\:2181

遇到该异常可能还有其他情况: 实体类没有实现java.io.Serializable,因为是远程服务,所有必须实现序列化接口

暂时就是这么些,欢迎大家补充!
