I have Developed an Spring Boot Application and it works without any problem. But I have some issues in Intellij: first: Auto Complete does not working in my JSP files and Java Classes are not recognized in my JSP files (I Blindly code in JSP files) second: It is not possible to click on jsp file name in Controller class and Navigate to the JSP file.

for example : return(index); >>> index is not clickable so it is not possible to navigate to jsp files in editor...I should Manually find JSP files.

How Can I resolve These problems Taking into Consideration when I build and run project with Maven it works without any problem. But Mentioned problems Bother me during writing code in intellij.
