SpringBoot去除内嵌tomcat的实现

SpringBoot内嵌tomcat，直接run Application即可，那么我们如何去除内嵌的tomcat，使用自己的呢？

一、POM(去除内嵌tomcat后，需要添加servlet依赖)

   
   org.springframework.boot
   spring-boot-starter-web
   
   
    
     org.springframework.boot
     spring-boot-starter-tomcat
    
   
  
  
  
   javax.servlet
   javax.servlet-api
   3.1.0
   provided
  

   
    maven-war-plugin
    3.0.0
   

打包方式设置成war

war

二、继承SpringBootServletInitializer重写configure方法

package com.example.export;

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 ExportApplication extends SpringBootServletInitializer {
 public static void main(String[] args) {
 SpringApplication.run(ExportApplication.class, args);
 }

 @Override
 protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
 return builder.sources(this.getClass());
 }

}

三、添加到tomcat容器、run 即可
