找不到Spring Boot JSP [英] Spring Boot JSP not found

问题描述

在我的Spring Boot应用程序中，我从Thymeleaf切换到JSP，并且在我的本地计算机上正常运行，但是当我将其上传到Heroku服务器时，我得到了
There was an unexpected error (type=Not Found, status=404). /WEB-INF/jsp/home.jsp

in my Spring Boot app I switched from Thymeleaf to JSP and it is working normally on my local computer, but when I upload it to Heroku server I get
There was an unexpected error (type=Not Found, status=404). /WEB-INF/jsp/home.jsp

它的jar被打包了，如果它在本地工作但不能在Heroku服务器上工作，那是什么意思?

its jar packaged, what does it mean if its working locally but not on Heroku server?

编辑，项目结构

推荐答案

尝试将其添加到pom.xml:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
    </dependency>

并将其添加到application.properties:

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

并将JSP移至src/main/webapp/WEB-INF/jsp.
