创建通用的Dubbo依赖项目

创建一个名为myshop-commons-dubbo项目，Dubbo需要创建服务提供者和服务消费者两个角色，他们都要依赖Dubbo的StarterPom，并且我们的项目都需要熔断机制，所以我们会提取出一个通用的项目以便于所有dubbo项目同意依赖

创建项目

添加自述文件

克隆到本地

复制过滤配置文件

新建pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <packaging>jar</packaging>

    <inceptionYear>2018-Now</inceptionYear>

        </dependency>
    </dependencies>
</project>

托管到intelliJ

创建源码目录

此处我们修改下myshop-dependencies中的pom中的dubbo-spring-boot-starter和spring-boot-starter-actuator的组和版本，actuator在starter-parent中有版本控制，所以不需要我们再声明版本号，如果我们需要指定版本号需要通过properties修改，如

<properties>
    <spring-data-releasetrain.version>Fowler-SR2</spring-data-releasetrain.version>
</properties>

org.apache.dubbo为apache孵化后的的新版本，比com.alibaba版本更强大一些，而org.springframework.boot
也相对com.alibaba而言对于健康检查actuator更强大一些（因为我在给hystrix配置servlet导包时导不进去了）

此时再修改myshop-comons-dubbo的pom

dependencyManagement与dependencies区别
　　dependencyManagement里只是声明依赖，并不实现引入，因此子项目需要显式的声明需要用的依赖。如果不在子项目中声明依赖，是不会从父项目中继承下来的；只有在子项目中写了该依赖项，并且没有指定具体版本，才会从父项目中继承该项，并且version和scope都读取自父pom;另外如果子项目中指定了版本号，那么会使用子项目中指定的jar版本。
　　dependencies即使在子模块中不写该依赖项，那么子模块仍然会从父项目中继承该依赖项（全部继承）。

scope 是用来限制 dependency 的作用范围的，影响 maven 项目在各个生命周期时导入的 package 的状态，主要管理依赖的部署。
scope 的作用范围：
（1）compile：默认值，适用于所有阶段（表明该 jar 包在编译、运行以及测试中路径均可见），并且会随着项目一起发布。
（2）test：只在测试时使用，用于编译和运行测试代码，不会随项目发布。
（3）runtime：无需参与项目的编译，不过后期的测试和运行周期需要其参与，与 compile 相比，跳过了编译。如 JDBC 驱动，适用运行和测试阶段。
（4）provided：编译和测试时有效，但是该依赖在运行时由服务器提供，并且打包时也不会被包含进去。如 servlet-api。
（5）system：类似 provided，需要显式提供包含依赖的jar，不会从 maven 仓库下载，而是从本地文件系统获取，需要添加 systemPath 的属性来定义路径。

为什么这两个依赖好使，为什么这两个版本好使？因为前面入门的时候我试过了，版本查看可以到

https://mvnrepository.com/

查看，方便

同时注意修改idea中关于maven仓库的配置，之前因为使用了错误的setting文件导致一直连不上私服

version：当一个接口的实现，出现不兼容升级时，可以用版本号过渡，版本号不同的服务相互间不引用；
<!-- start--服务提供者   -->
    <!-- 机器A提供1.0.0版本服务 -->
    <dubbo:service interface="com.xxx.ProviderService" version="1.0.0" />

    <!-- 消费任意一个版本服务 -->
    <dubbo:reference id="consumerService" interface="com.xxx.ProviderService" version="*" />
    <!-- end--服务消费者   -->


group：当一个接口有多种实现时，可以用group区分；
<!-- start--服务提供者   -->
    <!-- dubbo中当一个接口有多个实现类时，需要添加group来区分 -->
    <!-- 机器A：服务提供者 -->
    <bean id="zhenliangsongA" class="com.xxx.ServiceImplA" />

启动mysql
启动zookeeper
启动Dubbo-Admin

运行Application，服务可以注册到zookeeper

中间出现许多错误，比如缺少curator依赖，spring-boot-starter-parent版本低缺少类，升级后缺少hibernate-jpa-2.1-api的jar包，需要在dependencies中手动增加，同时domain中TbUser类的@Table注解中有错误，也未实现序列化，都需要手动增加，目前为止还在报无法连接redis的错误，但是可以注册到zookeeper。
