Solution 1:

If you want Spring Boot With JSPs in Executable Jars

Keep in mind that we will ultimately place the JSP templates under src/main/resources/META-INF/resources/WEB-INF/jsp/

Note : define the template prefix and suffix for our JSP files in application.properties

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

Then your can run jar file using below command :

java -jar 

 for your project you can below command

   java -jar  auth-1.3.5.RELEASE.jar

Solution 2:

JSP Limitations

When running a Spring Boot application that uses an embedded servlet container (and is packaged as an executable archive), there are some limitations in the JSP support.

With Jetty and Tomcat, it should work if you use war packaging. An executable war will work when launched with java -jar, and will also be deployable to any standard container. JSPs are not supported when using an executable jar. Undertow does not support JSPs. Creating a custom error.jsp page does not override the default view for error handling. Custom error pages should be used instead.

I have clone your GitHub project able to run project(if you follow below steps your problem will get solve definitely)

Step To run your project :

Step 1 : Create war package of your project

Step 2 : Run your war package using below command 

    java -jar  

    i.e for your project command should be like :

      java -jar  auth-1.3.5.RELEASE.war

Step 3 : Hit the URL  http://localhost:5000/

You can see the result in browser.
