Spring Boot JSP not found

问题

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

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

edit, project structure

回答1:

Try adding this to 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>

and adding this to application.properties:

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

and moving JSPs to src/main/webapp/WEB-INF/jsp.
