创建Maven的聚合工程步骤：  
创建的是一个聚合工程，在最外层是一个顶级工程，也就是父工程。

<packaging>pom</packaging>
    在这里插入代码片

添加依赖

在imall父工程的pom.xml中会自动添加所有的子工程：

<modules>
        <module>imall-common</module>
    </modules>

逆向生成代码（MyBatis Generator Mybatis逆向工程生成的代码）

                   selectByExampleQueryId="false"></table>
        </context>
    </generatorConfiguration>

构建imall-protal，引入依赖

<dependencies>
        
        <dependency>
            <groupId>com.situ</groupId>
            <artifactId>mall-mbg</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>com.situ</groupId>
            <artifactId>mall-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

因为module创建的web项目，需要在pom.xml中添加：

<build>
        <resources>
            <resource>
                <directory>src/main/webapp</directory>
                <targetPath>META-INF/resources</targetPath>
                <includes>
                    <include>**/**</include>
                </includes>
            </resource>
        </resources>
    </build>

在admin和portal中写一个application作为启动文件

package com.situ.mall;
    
    import org.mybatis.spring.annotation.MapperScan;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.core.env.Environment;
    import org.springframework.scheduling.annotation.EnableScheduling;
    
    // 声明该类是一个SpringBoot的引导类
    @SpringBootApplication
    // @MapperScan注解，扫描MyBatis Mapper接口类
    @MapperScan("com.situ.mall.mapper")
    @EnableScheduling
    public class AdminApplication {
        
        private static final Logger LOG = LoggerFactory.getLogger(AdminApplication.class);
    
        public static void main(String[] args) {
        
            // SpringApplication.run(WikiApplication.class, args);
            SpringApplication app = new SpringApplication(AdminApplication.class);
            Environment environment = app.run(args).getEnvironment();
            LOG.info("启动成功");
            LOG.info("地址:\thttp://127.0.0.1:{}", environment.getProperty("server.port"));
        }
    
    
    }
