1、import project -->> maven

2、setting -->> 配置maven

3、服務 配置maven tomcat 

4、直接啟動 使用run 

@SpringBootApplication
public class SpringBootWebApplication {

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

5、配合tomcat 使用

（1）新增類

/**
 * 修改啟動類，繼承 SpringBootServletInitializer 並重寫 configure 方法
*
 * @author linzhiyong
 * @email [email protected]
 * @time 2017/7/7
 * @desc
 */
public class SpringBootStartApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        
 
// 注意這裡要指向原先用main方法執行的Application啟動類
        return builder.sources(SpringBootWebApplication.class);
    }
}
