第2章 构建springboot工程 2-2 使用Spring官方STS搭建SpringBoot工程

项目名demo，SpringBoot的版本2.0.6

 

 

 

删了/demo/mvnw和/demo/mvnw.cmd。static文件夹包含静态文件，比如CSS、JS。templates文件夹是放模板的，SpringBoot官方推荐的模板是使用thymeleaf，SSM使用freemarker比较多。国产的Beetl也可以放到templates文件夹里面。

删掉/demo/src/test的内容，pom.xml删掉这一段

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

运行/demo/src/main/java/com/example/demo/DemoApplication.java

因为没有配置controler，所以它运行了一遍就关掉了。
