# spring boot+maven 生成多模块项目
Date: 2020-12-21


spring boot + maven配置, 创建一个包含多个模块项目的步骤

### 项目创建

使用[spring的initializr](https://start.spring.io/) 选择一下就可以生成代码

- 项目: tongda (jar)
- 模块: user (war) order (war) common (jar)

配置:

- Project : Maven Project
- Language : Java
- Spring Boot : 2.4.1
- Dependencies:
- Java : 11
- Packaging :jar/war

#### 调整 parent POM

修改tongda的`pom.xml`, 打包类型设置为`pom`

- 新增`packaging` 标签并设置为`pom`

```C
    <packaging>pom</packaging>
```

- 通知增加模块配置

```C
    <modules>
        <module>user</module>
        <module>order</module>
        <module>common</module>
    </modules>

```

- 各个模块中调整`parent`标签

`order`, `user`模块 `pom.xml`文件

```C
    <parent>
        <groupId>com.tongda</groupId>
        <artifactId>tongda</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath>../pom.xml</relativePath>
    </parent>   
```

- 验证

```C
> mvn clean package
...
