java - Spring mvc calling controller from jsp results in wrong url -
i new in developing spring mvc. trying call controller jsp file. gave requestmapping annotation controller, when try call mainview.jsp found on url: (i testing on localhost) "/airlinedb_spring/views/mainview.jsp" (this works fine), project name disappears url , address gives me 404: "/passengers/" don't know why "airlinedb_spring/" disappears link, looks main problem.
my controller code:
@controller @requestmapping(value="/passengers") public class passengercontroller{ @suppresswarnings("unchecked") @requestmapping(method=requestmethod.get) public string list(model model) { list<string> tl = new arraylist<string>(); tl.add("one"); tl.add("two"); tl.add("three"); model.addattribute("testlist", tl); return "mainview"; } my jsp file's code is:
<html> <head> <meta http-equiv="content-type" content="text/html; charset=us-ascii"> <title>airline database</title> </head> <body> <h2>passengers</h2> <a href="/passengers/">click</a> <c:foreach items="${model.testlist}" var="test" varstatus="loopstatus"> ${loopstatus.count} ${test}<br/> </c:foreach> </body> </html> my web.xml file:
<context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath*:web-inf/spring/*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <servlet> <servlet-name>airlinedb</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>airlinedb</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> the servlet-context.xml contains this:
<context:annotation-config/> <context:component-scan base-package="airlinedb.controller"/> <mvc:annotation-driven/> i searched through internet, found lot of problems in connection controller mapping, none of worked me, tried calling controller href="/passenger" got same 404. don't know configs missing, can see wrong url, have no idea might wrong. can me?
when <a href="/passengers/"> send like: http://localhost:8080/passengers/.
that's not want. want http://localhost:8080/airlinedb_spring/passengers/
so, either use <a href="/airlinedb_spring/passengers/"> or use that: <a href="${pagecontext.servletcontext.contextpath}/passengers/"> second option better pratice.
also, it's add mapping value requestmapping. try use follow:
@suppresswarnings("unchecked") @requestmapping(value="/",method=requestmethod.get) public string list(model model) { list<string> tl = new arraylist<string>(); tl.add("one"); tl.add("two"); tl.add("three"); model.addattribute("testlist", tl); return "mainview"; } add value="/" @requestmapping.
