## Maven父子结构的项目依赖使用以及打包依赖 ##

1：在父子结构项目中，如果要是用其他模块的类。在当前项目中的pom中 加入 其他模块的配置

<dependency>
          <groupId>com.spring.mySpring</groupId>
          <artifactId>mySpring-utils</artifactId>
          <version>0.0.1-SNAPSHOT</version>
     </dependency>

其中的groupId与artifactId还有version要与对应的模块一致

2：如果当前模块依赖其他模块，而且在打包的时候需要把依赖也打进去，则需要配置

<build>
         <plugins>
             <plugin>
                 <groupId>org.springframework.boot</groupId>
                 <artifactId>spring-boot-maven-plugin</artifactId>
                 
                 <configuration>
                        <mainClass>org.mySpring.service.TestService</mainClass>
                 </configuration>
                 <executions>
                     <execution>
                         <goals>
                             <goal>repackage</goal>
                         </goals>
                     </execution>
                 </executions>
             </plugin>
         </plugins>
     
     </build>

3：总的pom示例如下

<?xml version="1.0"?>
    <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <modelVersion>4.0.0</modelVersion>
      
      <parent>
        <groupId>com.spring.mySpring</groupId>
        <artifactId>mySpring-parent</artifactId>
        <version>0.0.1-SNAPSHOT</version>
      </parent>
      
      <artifactId>mySpring-service</artifactId>
      <name>mySpring-service</name>
      <url>http://maven.apache.org</url>
      
      <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      </properties>
      
      <dependencies>
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>3.8.1</version>
          <scope>test</scope>
        </dependency>
        
        
        <dependency>
          <groupId>com.spring.mySpring</groupId>
          <artifactId>mySpring-utils</artifactId>
          <version>0.0.1-SNAPSHOT</version>
        </dependency>
      </dependencies>
      
      
     <build>
         <plugins>
             <plugin>
                 <groupId>org.springframework.boot</groupId>
                 <artifactId>spring-boot-maven-plugin</artifactId>
                 
                 <configuration>
                        <mainClass>org.mySpring.service.TestService</mainClass>
                 </configuration>
                 <executions>
                     <execution>
                         <goals>
                             <goal>repackage</goal>
                         </goals>
                     </execution>
                 </executions>
             </plugin>
         </plugins>
     
     </build>
    </project>

## 微服务项目(maven父子级项目)怎么打包 ##

###### 项目层级结构： ######

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1OTA1MTU5_size_16_color_FFFFFF_t_70_pic_center]  
common中的是没有main方法的工具类，service中的是有main方法的业务代码。

###### 打包须知 ######

这种微服务项目或者说是maven父子级项目打包要解决的问题就是具体业务代码依赖工具类代码，利用idea的maven插件可以很方便做到。

*  在cloud\_parent，common，service这些上层文件夹管理模块中，添加`pom`
 *  在没有main方法的工具模块中只添加`jar`
 *  在具体的业务代码模块中添加：

<packaging>jar</packaging>
    
    <build>
    		//maven的打包插件
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
            
            //打包规则，打包时将resource文件夹打包进去
            <resources>
                <resource>
                    <directory>src/main/java</directory>
                    <includes>
                        <include>**/*.yml</include>
                        <include>**/*.properties</include>
                        <include>**/*.xml</include>
                    </includes>
                    <filtering>false</filtering>
                </resource>
                <resource>
                    <directory>src/main/resources</directory>
                    <includes>
                        <include>**/*.yml</include>
                        <include>**/*.properties</include>
                        <include>**/*.xml</include>
                    </includes>
                    <filtering>false</filtering>
                </resource>
            </resources>
    </build>

***根据maven的继承特性，我在service文件夹模块中添加***  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1OTA1MTU5_size_16_color_FFFFFF_t_70_pic_center 1]  
这样，只需在每个有mian方法的具体的业务模块中的pom中添加：

<build>
    		//maven的打包插件
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
    </build>

最终打包：只需对最顶层模块进行clean，install，在每个模块对应的target目录中找到jar包。

最后附上[maven][]配置：
