![wx20210817-211753@2x.png](/photos/wx20210817-211753@2x.png)

| 名称 | 说明 |
|--|--|
| Name | 项目名称，推荐使用英文单词组合创建名字，单词之间用英文减号“-”链接 |
| Languate | 项目语言，这里默认Java |
| Type | 依赖管理工具，这里默认Maven |
| Group | 组ID，应为公司域名倒叙写，如com.cn |
| Artifact | 项目唯一标识，推荐使用英文单词组合创建名字，单词之间用英文减号“-”链接，默认与项目名称一致 |
| Package name | 启动类所在包 |
| Project SDK | 这里选择1.8 |
| Java | java版本，这里与SDK同步，选择8 |
| Packaging | 打包方式，默认为Jar |

注意：这里SpringBoot的版本在 **2.1.2.RELEASE** 版本之上


# POM依赖

properties属性

```xml
<properties>
  <java.version>1.8</java.version>
  <spring-mybatis.version>2.1.4</spring-mybatis.version>
  <mysql.version>8.0.22</mysql.version>
  <druid.version>1.1.9</druid.version>
</properties>
```

dependencies依赖

1. SpringBoot项目必须依赖
```xml
<dependencies>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
  </dependency>
  <dependency>

  </dependency>
  <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <scope>test</scope>
  </dependency>
</dependencies>
```

2. wg-basic基础项目所需依赖
```xml
<dependencies>
  <!-- 角色模块，该模块包含权限模块、菜单模块、组织机构模块、用户模块、文件模块 -->
  <dependency>
    <groupId>ink.wgink</groupId>
    <artifactId>service-role</artifactId>
    <version>1.0-SNAPSHOT</version>
  </dependency>
  <!-- 登录模块，引入该模块后，访问系统需要登录 -->
  <dependency>
    <groupId>ink.wgink</groupId>
    <artifactId>login-base</artifactId>
