前言

spring-boot默认使用Tomcat作为内嵌的servlet容器，但是我们可以选择使用其它的容器比如：jetty、Undertow，下面我们试试将tomcat换成jetty

搭建一个简单的spring-boot项目

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <artifactId>cppba-jetty</artifactId>
    <version>1.0.0</version>
    <packaging>jar</packaging>
    <name>${project.artifactId}</name>

    <parent>
        <groupId>com.cppba</groupId>
        <artifactId>cppba-sample</artifactId>
        <version>1.0.0</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
    <build>
        <finalName>${project.artifactId}</finalName>
    </build>
</project>

JettyApplication.java

package com.cppba;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;

@SpringBootApplication
@EnableAsync
public class JettyApplication {
    public static void main(String[] args) {
        SpringApplication.run(JettyApplication.class, args);
    }
}

运行项目

我们可以看到tomcat的提示语句

切换jetty

修改pom依赖

其实很简单，我们只需要修改一下pom的依赖

<dependencies>
        <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>
    </dependencies>

运行项目

这时控制台打印的时jetty的提示语句
