之前学习mj老师的课程都是 自己修改成 SpringBoot项目 。贺老师的高级课都是直接创建。这边记录直接创建SpringBoot项目

创建项目

选择Spring Initializr

Dependencies：

Developer Tools

  • Lombok

Web

  • Spring Web

配置Maven

到设置里面 找到Maven

Preferences -> Build,Execution,Deployment-> Build Tools -> Maven

原样

Maven Home Path

选择本地自己安装的目录

image.png

/Users/hualande/Library/ApacheMaven

User settings file:

记得选中 override 选择配置文件 选择本地自己的Maven中的conf中的配置吧

/Users/hualande/Library/ApacheMaven/conf/settings.xml

Local repository:

记得选中 override

/Users/hualande/Library/ApachMavenRepository

自动创建的SpringBoot项目自带 .gitignore 忽略文件的

自带忽略文件 咱自己就不需要带了

打开项目后

Lombok Enable即可

对Application 进行运行即可

写一个最简单控制器(接口)

Test

单元测试模块

Test不会启动服务器的

分割线

在Main里面进行 Test 单元测试

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

把scope 隐藏即可

剔出 junit-vintage-engine

剔出原因

<exclusions>
    <exclusion>
        <groupId>org.junit.vintage</groupId>
        <artifactId>junit-vintage-engine</artifactId>
    </exclusion>
</exclusions>
