java - Spring MVC 4.1.7 WARNING: No mapping found for HTTP request with URI [/user] in DispatcherServlet -
i trying link annotation defined java controller requestmapping. specifically, localhost:8080/user , localhost:8080/signin
the index page loads fine, that's not due controller. must missing silly. i've been , down stack overflow looking solutions, far nothing has worked.
the popular answers warning seem adding context:component-scan, mvc:annotation-driven, or naming issues. seems have configuration in xml necessary, , some. missing project structure? or url pattern matching? mentioned jstl , adding c:tags urls, didn't work either.
i'm trying run latest, maybe there's issue? had trouble setting environment work webapp 3.1. of configuration happened automatically spring sts tool.
- java 8
- tomcat 8
- web app 3.1
- maven 4.0
- sts 3.7.0
