springboot不使用内置tomcat启动，用jetty或undertow

Spring Boot启动程序通常使用Tomcat作为默认的嵌入式服务器。如果需要更改 - 您可以排除Tomcat依赖项并改为包含Jetty或Undertow：

jetty配置：

<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>

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-jetty</artifactId>

</dependency>

@Bean

public JettyEmbeddedServletContainerFactory  jettyEmbeddedServletContainerFactory() {

    JettyEmbeddedServletContainerFactory jettyContainer =

      new JettyEmbeddedServletContainerFactory();

    jettyContainer.setPort(9000);

    jettyContainer.setContextPath("/springbootapp");

    return jettyContainer;

}

undertow配置:

<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>

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-undertow</artifactId>

</dependency>

@Bean

public UndertowEmbeddedServletContainerFactory embeddedServletContainerFactory() {

    UndertowEmbeddedServletContainerFactory factory =

      new UndertowEmbeddedServletContainerFactory();

    factory.addBuilderCustomizers(new UndertowBuilderCustomizer() {

        @Override

        public void customize(io.undertow.Undertow.Builder builder) {

            builder.addHttpListener(8080, "0.0.0.0");

        }

    });

    return factory;

}

9.在引导应用程序中配置Jetty或Undertow

Spring Boot启动程序通常使用Tomcat作为默认的嵌入式服务器。如果需要更改 - 您可以排除Tomcat依赖项并改为包含Jetty或Undertow：
