问题
I have problem with my spring boot web app. It uses embedded jetty (it must be jetty - not tomcat) and it uses jsp views. But seems like there is no way to make embedded jetty work with jsp views. Actually at the moment when I run mu app server starts successfully but when I try to access any url of my web app - I get error:

How can I make it work? Is there any way? And if it is not possible with spring boot then what are alternative ways to make my app work on embedded jetty with jsp?
Here is link to my project on github. Please look at it and help me! It would be just great if you try to run it in your IDE (IntelliJ IDEA recommended) and find the reason of the problem.

回答1:
You are using Spring Boot 1.3.6 and in the JSP limitations section of the documentation it says:
Jetty does not currently work as an embedded container with JSPs.
There's an enhancement coming in Spring Boot 1.4 that means the JSPs will work with embedded Jetty as long as you use war packaging. If you don't want to wait for 1.4.0 to be released, the enhancement is in 1.4.0.RC1 which is available from https://repo.spring.io/libs-milestone. There's also a new sample application that may be of interest.
