java - 在AWS上发布Springboot webapp 404索引错误

Question

我正在尝试学习 Java，并且我已经使用 Eclipse 和 Maven 完成了 Springboot 应用程序。我开始从https://start.spring.io/下载基地然后我创建了我的第一个 Controller 和 jsp 索引页面。但是当我尝试将其打包到 war 并将其发布到 AWS elasticbeanstalk 上时，我遇到了以下错误:

世界标准时间 2019 年 10 月 5 日星期六 09:42:45出现意外错误(类型=未找到，状态=404)。/WEB-INF/jsp/index.jsp

我声明:- 当我在计算机上运行网络应用程序时，它运行得很好!- 我已经在 AWS 上设置(在自定义变量中)更改 5000 上的端口

这是项目结构

作品集

- src
  - main
    - java
    - resources (where i have static and application.properties
    - webapp
      - WEB-INF
        - jsp
          - index.jsp
pom.xml

这是 pom.xml

这是application.properties

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp

这是我的主 Controller PortfolioApplication.java

package com.sofidis.portfolio;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;



@SpringBootApplication
public class PortfolioApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(PortfolioApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(PortfolioApplication.class);
    }

}

这是我的 HomeController

import com.sofidis.portfolio.model.*;
import javax.servlet.http.HttpSession;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController 
{

    @RequestMapping(value = "/")
    public String index( HttpSession session) 
    {

        PageMeta ptitle = new PageMeta();
        String titlepagina= ptitle.getPtitle("index");      
        session.setAttribute("pagetitle", titlepagina);

        PageMeta pdesc = new PageMeta();
        String descpagina= pdesc.getPdescription("index");      
        session.setAttribute("pagedescription", descpagina);

        return "index"; 

    }


}

这是index.jps

<%@ page isELIgnored="false"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>${pagetitle}</title>
<meta name="description" content="${pagedescription}">
<jsp:include page="./includes/common_head.jsp" />
</head>
<body>
 <p>Hello World</p>                             

</body>
</html>

非常感谢您的帮助!!我很绝望:((

Answer 1

在 WEB-INF 下，您应该只放置类、库、web.xml。 JSP 应放置在与 WEB-INF 相同的级别上，而不是放置在 WEB-INF 下。对于您的情况，应该如下所示:

webapp
  WEB-INF
    ...
  jsp
    index.jsp

之后还可能出现其他问题。但首先要改变结构。
