当我在Elastic Beanstalk上部署Spring Boot应用程序时找不到.jsp文件

Question

我有一个简单的Spring Boot Web应用程序，它应在本地运行。但是，当我在弹性beantalk上部署它时，出现404错误，提示未找到/WEB-INF/jsp/index.jsp。

这是我的pom.xml：

            </plugin>
        </plugins>
    </build>

</project>

和application.property文件：

server.port=5000
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
spring.mvc.static-path-pattern=/resources/**

这是我的控制器类：

package com.example.arge.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloController {

    @GetMapping("/")
    public String index() {
        return "index";
    }
}

index.jsp文件位于src / main / webapp / WEB-INF / jsp / index.jsp下。 一切似乎都还好，我不知道怎么了
