  1. 一开始遇到这个报错以为是我的product服务打包的问题，因为product-client模块打包失败，无法引入product-common，一直提示如下报错信息
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project product-client: Compilation failure: Compilation failure:
[ERROR] /D:/IdeaProjects/imooc/spring-cloud/product/client/src/main/java/com/imooc/product/client/ProductClient.java:[3,32] 程序包com.imooc.product.common不存在

[ERROR] /D:/IdeaProjects/imooc/spring-cloud/product/client/src/main/java/com/imooc/product/client/ProductClient.java:[15,10] 找不到符号
[ERROR] 符号:   类 ProductInfoOutput
[ERROR] 位置: 接口 com.imooc.product.client.ProductClient
[ERROR] /D:/IdeaProjects/imooc/spring-cloud/product/client/src/main/java/com/imooc/product/client/ProductClient.java:[18,42] 找不到符号
[ERROR] 符号:   类 DecreaseStockInput
[ERROR] 位置: 接口 com.imooc.product.client.ProductClient

所以我将product-common中的ProductOutput和DecreaseStock两个类放在了product-client模块中（ps之前的操作中在order-server模块提示缺少这两个类），使prodcut-client不在依赖product-commot模块，暂时完成了打包，
2. 虽然暂时完成了打包，可以遇到了最上面的order-server引用product-client后提示feignClassNotFound的报错信息，很自然的想到是product-client模块的打包的问题，在网上了很多文章例如
这篇文章maven多模块打包遇到问题详解中的在父工程pom文件中加入如下配置的

<plugins>
     <!--创建项目时自带的 -->
     <plugin>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-maven-plugin</artifactId>
     </plugin>
     <!-- 自己添加的 -->
     <plugin>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-maven-plugin</artifactId>
         <version>1.5.13.RELEASE</version>
         <executions>
             <execution>
                 <goals>
                     <goal>repackage</goal>
                 </goals>
             </execution>
         </executions>
     </plugin>
</plugins>

但是通过上面的配置仍然没有解决Product-client打包的问题（看来我对maven的了解还是不够呀），好吧继续找解决办法，终于在这篇IDEA maven 多模块打包问题总结解开了我的疑惑

如果在用maven构建多模块项目时，不要将此插件放到parent pom中，否则如果有sub module不是spring boot应用，在打包时就会出错。只将该插件添加到是spring boot项目的子模块。上面例子中common模块不是spring boot应用就不需要此插件，故不要将此插件放到shopping pom中

加上spring-boot-maven-plugin

<plugins>
     <!--创建项目时自带的 -->
     <plugin>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-maven-plugin</artifactId>
     </plugin>
</plugins>

不加spring-boot-maven-plugin后打包的结构，里面只有自己写的类

图片描述
个人的理解，在打包到本地仓库的jar包，product、product-client、product-common和product-server之间有依赖关系，所以即使order-server中只引用了product-client，而且product-client包中只有自己的类也可以使用到product-common中的类
3. 在Spring Boot 2下使用Feign找不到@EnableFeignClients的解决办法这篇文章中的方法感觉复杂本人并没有尝试

Spring Cloud对Feign的支持由org.springframework.cloud:spring-cloud-netflix-core移到org.springframework.cloud:spring-cloud-openfeign-core下,而Finchley.M9版本下的spring-cloud-starter-openfeign:2.0.0.M2的pom依赖文件中导入的是spring-cloud-netflix-core而非spring-cloud-openfeign-core,需要我们在pom文件中添加对应依赖管理使spring-cloud-starter-openfeign版本更新到2.0.0.RC1,如下图

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-openfeign</artifactId>
            <version>2.0.0.RC1</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>

其实到这里我还在纠结spring-cloud-starter-feign、spring-cloud-openfeign-core和spring-cloud-starter-openfeign的选择

对比一下上面M2版本的依赖树,可以很明显地看到与Feign相关的依赖包的变化是org.springframework.cloud:spring-cloud-netflix-core换成了org.springframework.cloud:spring-cloud-openfeign-core

直接看一下import信息,发现注解的类名为org.springframework.cloud.openfeign.EnableFeignClients,与上面看到的做对比,就可以发现@EnableFeignClients注解由org.springframework.cloud.netflix.feign.EnableFeignClients换为org.springframework.cloud.openfeign.EnableFeignClients

即在M2版本中@EnableFeignClients的类已经换了,但对应的spring-cloud-starter-openfeign下的依赖却没有更新,所以就找不到对应的类了

后来对比了两个依赖的结构后选择spring-cloud-starter-openfeign就好了
图片描述
对于当时为什么选择spring-cloud-openfeign-core，首先我的springboot版本为2.1.1，springcloud版本为Greenwich.M3，也是参考下面内容选择的

Spring Cloud对Feign的支持由org.springframework.cloud:spring-cloud-netflix-core移到org.springframework.cloud:spring-cloud-openfeign-core下,而Finchley.M9版本下的spring-cloud-starter-openfeign:2.0.0.M2的pom依赖文件中导入的是spring-cloud-netflix-core而非spring-cloud-openfeign-core,需要我们在pom文件中添加对应依赖管理使spring-cloud-starter-openfeign版本更新到2.0.0.RC1,如下图

最后总结一下，第一是自己对spring cloud组件的使用不熟，引入组件依赖的套路spring-cloud-starter-*；第二尝试太新的版本，不按照课程中的版本当然要入坑了；不过对于我来说按照课程学习内容虽好，通过解决版本使用中遇到的问题更是一种挑战和进步
