完成下图操作保存即可
配置tomcat启动项
配置视图解析器
创建一个springboot主程序
@SpringBootApplication
public class SpringBootMain {
public static void main(String[] args) {
SpringApplication.run(SpringBootMain.class,args);
}
}
必须编写一个SpringBootServletInitializer的子类，并调用configure方法里面的固定写法
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
//传入SpringBoot的主程序，
return application.sources(SpringBootMain.class);
}
}
然后启动tomcat，控制台输出了spring就启动成功了
