springBoot集成dubbo UserAddress address1 = new UserAddress(1, “北京市昌平区”, “1”, “李老师”, “010-56253825”, “Y”);UserAddress address2 = new UserAddress(2, “深圳市宝安区”, “1”, “王老师”, “010-56253825”, “N”);4：服务消费者基于软负载均衡算法调用服务提供者的服务，这个服务提供者有可能是一个服务提供者列表，调用那个服务提供者就是根据负载均衡来调用了。阅读详情

参考

dubbo官网：https://cn.dubbo.apache.org/zh-cn/overview/quickstart/java/spring-boot/
他人博客：https://blog.youkuaiyun.com/weixin_59334478/article/details/126725073

dubbo官网的改了改，不好使。别人的博客参考了下，可用。

项目结构

study：父模块，集中管理jar包版本等。api、provider、consumer是study的子模块
api：只提供接口，供服务提供者、服务消费者使用。
provider：服务提供者，依赖api模块。实现了api暴露的接口。
consumer：服务消费者，依赖api模块。调用api暴露的接口。

工作实践中，若想使用A部门的接口，只需要依赖A部门的api jar包aaa.jar，然后通过rpc远程调用A部门的服务。而aaa.jar中只有接口，没有更多内容，避免过多暴露内容。暴露的内容越少，以后事儿越少，避免改东西还得考虑下游系统。

编码

在这个springboot集成dubbo的实例中，注册中心使用zookeeper，因此首先安装、启动zookeeper。
项目中需要一个父模块，集中管理公共内容，因此新建个项目study，里面依赖了springboot对应的jar，并通过dependencyManagement集中管理公共jar的版本。
api模块只需要提供接口，没有其他内容，因此非常简洁干净。
provider需要依赖api模块，并实现api对应的接口。需要集成dubbo，需要集成zookeeper作为注册中心。
consumer需要依赖api模块，调用api对应的接口。需要集成dubbo，需要集成zookeeper作为注册中心，需要集成web写controller做测试。

zookeeper

zookeeper安装、启动参考：https://blog.youkuaiyun.com/ludkjava/article/details/134628293
zookeeper内容看起来麻烦，可以再弄个图形化界面工具prettyzoo，看起来更直观。
prettyzoo安装参考：
