这里我们将向您展示一个示例 - 在 Spring Boot 中使用 Undertow 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 Undertow 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** ####

移除 spring-boot-starter-web 上已有的 tomcat 依赖，添加 undertow 依赖

#### **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** ####
