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>

打包方式设置成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;@SpringBootApplicationpublic 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
