Spring boot web app with jsp file extension in the url - spring-boot

Question

We have a legacy web app that uses the url below:
https://example.com/forms/forms.jsp
We have rewritten the legacy code to use spring boot web app with the url https://example.com/forms without .jsp extension in the url.
In order to keep the old url, which is a business requirement, I followed this Spring MVC #PathVariable with a dot (.) gets truncated. However, it only works when there is a / https://example.com/forms/forms.jsp/ in the url.
I googled it, found some suggestions in stack overflow and tried a couple of different approaches. But not quite working.
UPDATES:
I just found this post on jsp in the url. I updated from #GetMapping("/forms/{jspName:.+}") to #GetMapping(path = "/forms/{jspName:.+}"). This made it possible to check the pathVariable in the if statement. However, the return statement does not return the expected forms.jsp file as before; instead it gives 404 error.
url : http://localhost:8080/forms/forms.jsp
#GetMapping(path = "/forms/{jspName:.+}")
public String getForms(#PathVariable("jspName") String jspName) {
if (jspName.equalsIgnoreCase("forms.jsp")) {
log.debug("JSP file is {}", jspName);
return "forms";
}
return "index";
}
Console:
[nio-8080-exec-1] c.n.e.c.EthicsEmailFormController : JSP file is forms.jsp
404 Error:
No webpage was found for the web address: http://localhost:8080/forms/forms.jsp
HTTP ERROR 404
application.properties - The forms.jsp is stored under /WEB-INF/views/page/forms.jsp.
spring.mvc.view.prefix=/WEB-INF/views/page/
spring.mvc.view.suffix=.jsp
For comparison:
Below works when the url is https://example.com/forms/forms.jsp/ with a / at the end of the url. But the existing url (that is specified in the requirement) does not contain a / at the end of the url. It has to be https://example.com/forms/forms.jsp.
#GetMapping("/forms/{jspName:.+}")
public String getForms(#PathVariable("jspName") String jspName) {
log.debug("Jsp file name = {} ", jspName);
return "forms";
}
I saw some suggestion is to remove below dependency. I also do NOT have below dependency in pom.xml.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
Any suggestions? Thanks a lot!

Since this app is for training only, I moved the jsp file to webapp/forms.forms.jsp folder. This way, the jsp file can be accessed directly from the url below:
https://example.com/forms/forms.jsp
There is no need to go through a controller. Thanks to my friend Barry for his suggestion. Thanks!
