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>

</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>

打包方式设置成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
