Answer
Springboot and jsp does not work properly with jar packaging due to a hardcoded pattern in tomcat. So, it’s preferable to use war packaging along with springboot if you are using jsp as view render and deploying in tomcat.
The issue is that when you are using jar
to deploy a springboot application , the jsp files will not be present in the tomcat and while trying to serve the request you will get a 404 PAGE NOT FOUND. This is because of the jar packaging ,that the jsp files are not getting copied from the WEB-INF folder.If you keep the jsp files under the META-INF/resources
folder while using jar as packaging it should work.But springboot documentation itself makes it clear that it is preferable to use war as packaging along with jsp.
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.
