Springboot使用外部的Servelt容器（最简单的方式）

第一步、修改POM.xml文件

         将SpringBoot内置的Tomcat排除替换原有的部分依赖并添加api依赖

		<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>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId></dependency>

第二步、修改启动类

                需要继承SpringBootServletInitializer

package com.qcby.springbootusemvc;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;@SpringBootApplication
public class SpringbootusemvcApplication extends SpringBootServletInitializer {public static void main(String[] args) {SpringApplication.run(SpringbootusemvcApplication.class, args);}protected SpringApplicationBuilder configure(SpringApplicationBuilder builder){return builder.sources(SpringbootusemvcApplication.class);}
}

第三步、添加controller

package com.qcby.springbootusemvc.controller;import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/exam")
public class ExampleController {/*** Springboot 使用外部的tomcat** @Author 刘庆亮* @Date 2025-07-22 16:26* @param: null* @return null*/@GetMapping("/getCity")public String getCityInfo() {return "杭州";}}

第四步、添加外部的Tomcat

                        

                         

 

 

 第五步、添加application.yaml

server:port: 18081servlet:context-path: /example-demo

第六步、启动（不许再启动类哪里启动一定要在下面标注的地方在启动！！！）

最后一步、在网址搜索 http://localhost:8080/hub_demo/exam/getCity

代码已经放到远程仓库需要自取
