springBoot項目打war包部署到tomcat上

1 首先得在本地跑通.

2 處理啟動類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上必須要繼承SpringBootServletInitializer類,並重寫configure方法

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

4 打war包

5 target文件夾下面就有war包了

6 復制war放到tomcat下的webapps文件夾即可 , 啟動tomcat他會加載你的war包生成一個文件夾,這就是你的項目了
