> 生成war包
项目启动类Application.java 继承 SpringBootServletInitializer并重写configure方法
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}

DemoController.java
@RestController
@RequestMapping("/test")
public class DemoController {
    @RequestMapping("/home")
    public String home() {
        return "DemoController/home";
    }
}
