spring boot-jsp專案main啟動出現process finished with exit code 0 錯誤

百度有人說是因為pom.xml中缺少web的依賴，但是我pom.xml是有這個web的依賴的，而以前的話，這個專案是可以啟動的，但現在卻無法啟動，只能是用war的方式部署到tomcat才行，可是我需要的是用main的方式一鍵啟動。
然後突然想到了spring boot已經出到了2.0了，我想會不會是版本過老了，版本號是1.4.7；
我就只發成功的demo吧，有需要的可以參考一下，不當之處歡迎批評指點.
啟動器：
import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class ApplicationTest { public static void main(String[] args) { SpringApplication.run(ApplicationTest.class, args); } }
application.properties:
spring.mvc.view.prefix=/WEB-INF/jsp/ spring.mvc.view.suffix=.jsp
controller:
import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @RequestMapping("/jsp") @Controller public class JspTestController { @RequestMapping("/test") public ModelAndView test() { //檢視需要根據application.properties中配置的路徑下存在 ModelAndView mv = newModelAndView("test"); mv.addObject("msg", "資料來自後臺..."); return mv; } }
jsp（注意路徑:WEB-INF/jsp/test.jsp）:
