springBoot项目打war包部署到tomcat上

1 首先得在本地跑通.

2 处理启动类Application

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }
}
注 : 部署到tomcat上必须要继承SpringBootServletInitializer类,并重写configure方法

3 pom.xml中  <packaging>war</packaging>　　-设置成war

4 打war包

5 target文件夹下面就有war包了

6 复制war放到tomcat下的webapps文件夹即可 , 启动tomcat他会加载你的war包生成一个文件夹,这就是你的项目了
