Preface: Combined with the previous article “[java] [Refactoring 1] Practical Module Development and Design”, version locking is carried out to clarify the difference between dependencyManagement and dependencies.
1. Create dependencyManagement tag
Create dependencyManagement and dependencies in the parent module
<!-- 7. Version locking -->
<dependencyManagement>
<dependencies>
</dependencies>
</dependencyManagement>
2. Set labels for dependent versions that require version control
Springboot project does not require control
<properties>
<java.version>1.8</java.version>
<!-- 8. Custom attributes -->
<lombok.version>1.18.24</lombok.version>
<aliyun-sdk-oss.version>3.15.1</aliyun-sdk-oss.version>
<jaxb-api.version>2.3.1</jaxb-api.version>
<activation.version>1.1.1</activation.version>
<jaxb-runtime.version>2.3.3</jaxb-runtime.version>
<mybatis.version>2.3.1</mybatis.version>
<mysql-connector-j.version>8.0.31</mysql-connector-j.version>
<pagehelper.version>1.4.6</pagehelper.version>
<fastjson.version>1.2.76</fastjson.version>
<jjwt.version>0.9.0</jjwt.version>
<!-- No configuration is required because springboot is already version controlled -->
<!--
<spring-boot-starter-test.version>2.7.5</spring-boot-starter-test.version>
<spring-boot-starter-aop.version>2.7.5</spring-boot-starter-aop.version>
<spring-boot-starter-web.version>2.7.5</spring-boot-starter-web.version>
-->
</properties>
3. Migrate dependencies that require version control from each sub-module to here
Use the tags set in the second step for version control
<!-- 7. Version locking -->

4. Version control the dependencies of the parent module

Six. Packing
1. Make sure the codes can be executed without errors
slightly
3. Complete bocai-parent pom
4.0.0 org.springframework.boot spring-boot-starter-parent 2.7.5 com.bocai bocai-parent 0.0.1-SNAPSHOT pom <!-- 8.

3. Packaging
Select the package of the parent bocai-parent life cycle
Seven. Use jar to start the service
The key here is that the pom of bocai-web-management requires the build tag
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<excludes>
<exclude>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
</build>
#cmd window java -jar packaged jar package
