SpringBoot项目打war包

1.pom文件打包方式修改为war

<packaging>war</packaging>

2.spring-boot-starter-tomcat的scope属性设置为provided

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

3.添加ServletInitializer类

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
 
public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(PlatformApplication.class);
    }
}

注：PlatformApplication为SpringBoot的启动类
