spring boot

/src/main/java/hello/ServletInitializer.java   加入这个文件 到Application同级目录 部署到tomcat 就没错了

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import hello.Application;
public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

}
