Spring Boot 使用 jetty 作为默认的Web容器

更换 SpringBoot 中默认的web 容器为 jetty 仅需两步

第一步：去除springboot 中默认的Tomcat 依赖。

<dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.bootgroupId>
                    <artifactId>spring-boot-starter-tomcatartifactId>
                exclusion>
            exclusions>
        dependency>

第二步：添加 jetty 依赖。

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

完成 POM 文件：

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
