SpringBoot logic abnormal unified treatment

Building project

We abnormal extracted core logic processing section as a separate jarsupply of other modules references, create a project parentitem pom.xmladded to rely on public use, the configuration shown as follows:

<dependencies>
        <!--Lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <!--测试模块依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!--web依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
</dependencies>

 

After the project is created in addition to .idea, iml, pom.xmlretention, others are deleted.

For various reasons, we can only put part of the code, can provide ideas.
