Build a multi-module maven project

1. Open the idea, new project

Delete src folder

2, a jar of the new module

We created a common project of the module
we talk pom files in the project to see the system automatically join the common this module

we enter the common module pom file, the introduction of the root item pom

2, a new module of war

We check on the create form archetype options

 </parent>

Join in what dependencies dependent

 <dependency>
    <groupId>org.springframework.boot</groupId>

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

2), in the webapp pom file
by adding the following dependencies in the dependency

    <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
       </dependency>
