昨天发布了注解方式,有人给我发了邮件希望能出一版本xml格式的,本来12点前能搞定的但是电脑稍微出了问题,导致idea 疯狂奔溃,搞了很久废话不多说了,有错误之处望大家指出发我邮箱.
用dubbo肯定是多模块化了 所以我们先创建一个聚合项目
这是项目结构
dubbo_demo 的pom 这个主要用来聚合业务模块用不做任何业务处理

然后按照上面的方法创建两个项目一个是 服务的提供者 和服务的消费者
提供者和消费者不懂的话点击这个连接了解一下 http://dubbo.io/
服务提供者代码片段:
生成基本项目按第一个图片的去生成
代码结构: 由于是demo不按规范结构来看得懂就行
服务提供者pom :

接下来就是服务消费者了:
项目结构:
消费者pom 也是要注意pom中和上面有哪些不一样 和 多了那个依赖

dubbo.xml配置:
启动类:
测试调用服务controller
接下来就是先把服务提供者启动起来 然后在启动消费者
运行结果
