spring-boot-starter-tomcat和spring-boot-starter-web [英] spring-boot-starter-tomcat vs spring-boot-starter-web

问题描述

我正在尝试学习Spring boot，我注意到有两种选择.

I'm trying to learn Spring boot and I notice there are two options.

1. spring-boot-starter-web-根据文档，它支持全栈式Web开发，包括Tomcat和web-mvc

1. spring-boot-starter-web - which according to the docs gives support for full-stack web development, including Tomcat and web-mvc

spring-boot-starter-tomcat

spring-boot-starter-tomcat

由于#1支持Tomcat，为什么要使用#2?

Since #1 supports Tomcat why would one want to use #2?

有什么区别?

谢谢

推荐答案

由于#1支持Tomcat，为什么要使用#2?

Since #1 supports Tomcat why would one want to use #2?

spring-boot-starter-web包含spring-boot-starter-tomcat.如果不需要spring mvc(包含在spring-boot-starter-web中)，则可以单独使用spring-boot-starter-tomcat.

spring-boot-starter-web contains spring-boot-starter-tomcat. spring-boot-starter-tomcat could potentially be used on its own if spring mvc isn't needed (contained in spring-boot-starter-web).

这是spring-boot-starter-web的依赖项层次结构:

Here is the dependency hierarchy of spring-boot-starter-web:

有什么区别?

What are the differences?

spring-boot-starter-web包含spring web依赖项(包括spring-boot-starter-tomcat):

spring-boot-starter-web contains spring web dependencies (including spring-boot-starter-tomcat):

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

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

spring-boot-starter-tomcat包含与嵌入式tomcat服务器相关的所有内容:

spring-boot-starter-tomcat contains everything related to an embdedded tomcat server:

core
el
logging
websocket

core
el
logging
websocket

如果您想在没有嵌入式tomcat服务器的情况下使用spring mvc怎么办?

What if you want to use spring mvc without the embedded tomcat server?

只需将其从依赖项中排除:

Just exclude it from the dependency:

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