### 解决maven下载不了jar的问题 ###

### Maven工程落地细节复习 ###

**1、Maven中的dependencyManagement和dependencies**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzIxMDQwNTU5_size_16_color_FFFFFF_t_70_pic_center 5]

--------------------

**2、maven中跳过单元测试**

### 父工程创建完成执行mvn:install将父工程发布到仓库方便子工程继承 ###

mvn:install

### 3.工程重构 ###

**为什么？**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzIxMDQwNTU5_size_16_color_FFFFFF_t_70_pic_center 10]  
因为两个模块有重复的东西。

--------------------

1、新建cloud-api-commons  
2、改pom

3、把公共的实体类复制过来

4、执行maven clean和 install

5、删除80和8001模块的实体类，然后引入依赖

<dependency>
        <groupId>com.sl.springcloud</groupId>
        <artifactId>cloud-api-commons</artifactId>
        <version>${project.version}</version>
    </dependency>
