这里我们将向您展示一个示例 - 在 Spring Boot 中使用 Jetty 作为嵌入式服务器

对于 Spring Boot 应用程序，您可以生成一个包含Embedded Tomcat 或 Undertow 或 jetty的应用程序 jar 。您可以将 Web 应用程序作为普通 Java 应用程序运行！这样做的好处是您不需要在部署环境中预先安装服务器。

下面我们将展示一个使用 Jetty 作为嵌入式服务器的简单 Spring Boot 应用程序示例。

**1. Maven/依赖管理 \[pom.xml\]**

移除对 spring-boot-starter-web 的现有 tomcat 依赖并添加 jetty 依赖

            <plugins>

            </plugins>
        </build>
        <url>www.knowledgefactory.net</url>
    </project>

**2. 测试控制器**

package com.knowledgefactory.knowledgefactorydemo;
     
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class Controller {
     @RequestMapping(value = "/hello", method = RequestMethod.GET)
     public ResponseEntity<String> listAllUsers() {
        return new ResponseEntity<String>("Greetings from knowledgefactory", 
                                                     HttpStatus.OK);
     }
    }

**3. Spring Boot - 主类**

package com.knowledgefactory.knowledgefactorydemo;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class KnowledgefactorydemoApplication {
      public static void main(String[] args) {
             SpringApplication.run(KnowledgefactorydemoApplication.class, args);
         }
    }

**4.运行**

$ mvn spring-boot:run

**5. 测试**

http://localhost:8080/hello
