02、SpringBoot-切换内置web服务器
SpringBoot内置服务器自动装配源码:
包名:
org.springframework.boot.autoconfigure.web.embedded
自动装配类:

排除tomcat内置服务器:
pom文件中查看并引入jetty服务器:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!--排除tomcat依赖--> <exclusions> <exclusion> <artifactId>spring-boot-starter-tomcat</artifactId> <groupId>org.springframework.boot</groupId> </exclusion> </exclusions> </dependency> <!--引入jetty的依赖--> <dependency> <artifactId>spring-boot-starter-jetty</artifactId> <groupId>org.springframework.boot</groupId> </dependency>
