为什么springboot不需要我们去配置那么繁琐的东西?
我们直接看pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.gong</groupId> <artifactId>myspringboot</artifactId> <version>1.0-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> </parent> <dependencies> <!--引入springboot的web支持，帮你封装好了很多个依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
首先看spring-boot-starter-parent，spring-boot-start就是场景启动器，这是所有项目的父项目，我们ctrl+鼠标左键点进去：
新文件的开头部分：
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>1.5.9.RELEASE</version> <relativePath>../../spring-boot-dependencies</relativePath> </parent>
它的父项目是spring-boot-dependencies，用于管理依赖包的版本号。也就是说spring-boot-start-parent是版本仲裁中心。
再来看spring-boot-starter-web，我们来查看其中有什么：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starters</artifactId> <version>1.5.9.RELEASE</version> </parent> <artifactId>spring-boot-starter-web</artifactId> <name>Spring Boot Web Starter</name> <description>Starter for building web, including RESTful, applications using Spring MVC. Uses Tomcat as the default embedded container</description> <url>http://projects.spring.io/spring-boot/</url> <organization> <name>Pivotal Software, Inc.</name> <url>http://www.spring.io</url> </organization> <properties> <main.basedir>${basedir}/../..</main.basedir> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </dependency> </dependencies> </project>
这里面才是帮我们导入了真正所需的依赖包。
springboot还有许多场景启动器，例如AOP、邮件开发等等。我们只需要在项目里面引用这些starter，这些场景的相关依赖包就会自动导入出来。
