02、SpringBoot-切换内置web服务器

SpringBoot内置服务器自动装配源码:

包名:

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>
