i notice 2 issues provided code.
first form submits hello.html, @requestmapping mapped /hello. fix adjust @requestmapping:
@requestmapping(value = "/hello.html") public class helloworldcontroller second when using @requestmapping must add following line dispatcher-servlet.xml file enable spring mvc annotations such @requestmapping:
<mvc:annotation-driven/>
