Idea搭建SpringBoot多模块项目

需求:

  搭建一个多模块项目,包含下面三个模块

    sync-common

    sync-mimall

    sync-youpin

1、先搭建父工程

  方式一、SpringBoot

  1)File-New-Project-Spring Initializr

   2)Next

  选择打包方式(jar/war),Artifact/Name 工程名称,包路径等信息

   3)Next

  选择SpringBoot版本

   4)Next

  确认工程名称和工程本地存储路径,然后点击Finish父工程即创建完成

   5)删掉src目录

  因为我们创建的是父工程,只作为管理工程,里面还有子模块,因此不需要src目录,删掉即可

   

  6)修改pom.xml

    <groupId>com.xiaomi.mitv.mall.sync</groupId>
    <artifactId>mitv-mall-sync</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>mitv-mall-sync</name>
    <packaging>pom</packaging>  <!--修改jar为pom-->
    <description>Demo project for Spring Boot</description>

  

  方式二、maven

   1)File-New-Project-Maven

  2)Next

  3)Next

  确认工程名,然后点击finish即完成

  4)删除src目录

2、创建启动子模块(可部署)

   1)在创建的工程名上右键 New-Module-Spring Initializr

   2)Next

  输入模块名,包名等相关信息

  3)Next

   选择SpringBoot版本和相关依赖,如果是Web项目,选择Web依赖

  4)Next

  确认模块名和模块路径,点击Finish完成

  5)在父pom.xml中添加刚创建的子模块

  <modules>
        <module>sync-common</module>
        <module>sync-mimall</module>
        <module>sync-youpin</module>
    </modules>

  6)修改子模块pom.xml parent

    <parent>
        <artifactId>mitv-mall-sync</artifactId>
        <groupId>com.xiaomi.mitv.mall.sync</groupId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath>../pom.xml</relativePath>
    </parent>

 

3、创建普通子模块(仅作为启动模块的依赖,如common模块)

   1)在创建的工程名上右键 New-Module-Maven

   2)Next

  3)Next

  确认模块名,点击Finish即完成。父pom.xml中会自动在modules标签内添加新增的子模块

  4)修改子模块pom.xml parent

    <parent>
        <artifactId>mitv-mall-sync</artifactId>
        <groupId>com.xiaomi.mitv.mall.sync</groupId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath>../pom.xml</relativePath>
    </parent>

   

  5)若不需要,如common模块,删除resources和test 目录

4、区分环境配置

  1)项目结构

  

  新建sync-deploy目录,里面包含三个环境的配置

  2)其中一个部署模块的pom配置

<build>
        <!--指定配置文件的地址,里面的配置会作为参数替换其他配置文件的占位符-->
        <filters>
            <filter>../sync-deploy/config/${active.env}/config.properties</filter> <!-- 多个文件可配置多个filter -->
        </filters>
        <resources>
            <resource>
                <directory>${basedir}/src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>

    </build>

                                </configuration>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>

  3)打包后,将对应环境下的文件复制进了target/classes目录中,并解析了其中的占位符
