spring initializr:spring-boot-starter vs spring-boot-starter-web [英] spring initializr: spring-boot-starter vs spring-boot-starter-web

问题描述

我正在尝试在IntellIJ中开发一个基于示例Spring Boot的应用程序.因此，我使用spring Initialzr方法，并在设置过程中进行了默认选择.我最终得到的pom.xml具有以下依赖关系:

I am trying to develop a sample spring boot based application in IntellIJ. So I used spring Initialzr approach, and made default selections during the setup. The pom.xml I ended up with has following dependency:

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

但是我关注的教程如下:

But the tutorial I am following has following:

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

那么，有什么区别?我可以同时拥有吗?

So, what's the difference? And can I have both?

推荐答案

spring-boot-starter-web包含以下依赖项:

spring-boot-starter-web contains the following dependencies:

• spring-boot-starter
• jackson
• spring-core
• spring-mvc
• spring-boot-starter-tomcat

使用IntelliJ，您可以在项目结构的底部查看工件的依赖性.

Using IntelliJ, you can view the dependencies of your artifacts at the bottom of the project structure.

鉴于spring-boot-starter是spring-boot-starter-web的依赖项，因此两者都没有用.如果两者都保留，则不会有任何危害，只是不必要的.

Given that spring-boot-starter is a dependency of spring-boot-starter-web, it would be useless to have both. It wouldn't do any harm if you kept both either, just unnecessary.
