springboot项目jsp打包war运行步骤

（一）修改代码只需要2步：

（1）主进口类

@SpringBootApplication
@MapperScan("com.wbq.dgshop.dao")
public class DgshopApplication  extends SpringBootServletInitializer {

	public static void main(String[] args) {
		SpringApplication.run(DgshopApplication.class, args);
	}
	@Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DgshopApplication.class);
    }
}

（2）pox.xml文件把jar改成war

（二）打包步骤

（1）eclipse内的项目选中右键--》Run As--》Maven clean

（2）eclipse内的项目选中右键--》Run As--》Maven build

弹出的窗口--》Goals --》输入：clean install，，再选中Skip Tests

如下图：

（3）拷贝生成的war包到tomcat运行，OK。
