SpringBoot笔记-day01
在pom.xml中
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.1.RELEASE</version> </parent>
spring-boot-starter-parent
是所有springboot启动以来的父类，所有的springboot都必须继承这个
<dependencies> <!--web功能的起步依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--热部署配置--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> </dependency> </dependencies>
启用热部署参考 https://www.jianshu.com/p/f658fed35786
热部署作用：热部署，就是在应用正在运行的时候升级软件，却不需要重新启动应用。
<!--web功能的起步依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>
这一部分中，里面就包含了springmvc的依赖
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.0.5.RELEASE</version> <scope>compile</scope> </dependency>
还有下面的依赖
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <version>2.0.1.RELEASE</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-json</artifactId> <version>2.0.1.RELEASE</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <version>2.0.1.RELEASE</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.hibernate.validator</groupId> <artifactId>hibernate-validator</artifactId> <version>6.0.9.Final</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>5.0.5.RELEASE</version> <scope>compile</scope> </dependency>
里面主要有spring-web、spring-boot-starter-tomcat、spring-boot-starter-json几个比较重要的springweb的依赖，这就是为什么spring boot中自带有tomcat的缘故了，跟本地的tomcat无关。
