springboot发布到独立的tomcat中运行

springboot发布到独立的tomcat中运行

1. 将打包形式修改成war包

   <packaging>war</packaging>

2. 将springboot的默认内嵌tomcat排除掉

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
   </dependency>

3. 修改项目启动方式
   写一个SpringBootServletInitializer 子类，并覆盖它的 configure 方法，这个子类可以是应用的主类，也可以另外写一个类

package com.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class MyApplication extends SpringBootServletInitializer {

    @Override  
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {  
        return application.sources(MyApplication .class);  
    }  

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