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)

<dependency>  
  <groupId>org.springframework.boot</groupId>  
  <artifactId>spring-boot-starter-web</artifactId>  
  <!-- 去除内嵌tomcat -->  
  <exclusions>  
    <exclusion>  
      <groupId>org.springframework.boot</groupId>  
      <artifactId>spring-boot-starter-tomcat</artifactId>  
    </exclusion>  
  </exclusions>  
</dependency>  
<!--添加servlet的依赖-->  
<dependency>  
  <groupId>javax.servlet</groupId>  
  <artifactId>javax.servlet-api</artifactId>  
  <version>3.1.0</version>  
  <scope>provided</scope>  
</dependency>  
  
  <plugin>  
    <artifactId>maven-war-plugin</artifactId>  
    <version>3.0.0</version>  
  </plugin>

并且设置成war

<packaging>war</packaging>

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());  
    }  
  
}
