JSP page/file is not rendering in Spring Boot application


Sometimes you might be facing the problem that JSP page/file is not rendering in Spring Boot application. It will be downloaded when you call the controller that renders your JSP page/file.

All we know, Spring Boot uses the embedded Tomcat Server which does not include JSP compiler jar, so the Spring Boot application failed to compile the JSP page/file into the servlet and page will be downloaded.

To resolve this problem, you need to add JSP compiler jar i.e. Tomcat Jasper in your Spring Boot application.

pom.xml
<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-jasper</artifactId>
    <version>9.0.1</version>
</dependency>

Choose an appropriate version of Tomcat Jasper matches with your application. Check out the MVN Repository.
