基于springboot和dubbo搭建SOA服务

环境依赖

• JDK: version 6 or higher
• Maven: version 3 or higher

注册中心搭建

• zookeeper机器搭建

详见zookeeper搭建

dubbo监控中心搭建

dubbo-admin 本地编译打包

dubbo的所有源码可在https://github.com/alibaba/dubbo上下载。下好之后解压

dubbo-admin部署

• 安装
  将 dubbo-admin-2.5.4-SNAPSHOT.war 拷入 tomcat webapps中
• 配置
  修改tomcat的端口8088，修改方法如下，打到conf下的文件 server.xml，因为zookeeper会用到8080的端口，所以为了不冲突，把Tomcat的端口改一下。

服务搭建

• maven 依赖

<dependency>    <groupId>com.alibaba</groupId>    <artifactId>dubbo</artifactId>    <version>2.5.5</version></dependency>

• 配置
