Start the project with main method and access localhost:8080 you can see the page.
Notice
At first I make a directory in src/main like webapp/WEB-INF/jsp and put all jsp in it. When I try to access root path with main method I got 404 page. I found there is no jsp file in jar. I changed the pom file like following
<packaging>war</packaging>
