java - No mapping found for HTTP request with URI (spring 4.1 annotation configuration) -

first of all, please don't lock thread, please. i've read questions, , still cannot solve problem. i'm studying how utilize annotation on spring without configuring xml files. i'm stucking error:

no mapping found http request uri [/web-inf/index.jsp] in dispatcherservlet name 'dispatcherservlet'

this configuration class:

@componentscan(basepackages = "com.sample.spring") @enableautoconfiguration @enablewebmvc @org.springframework.context.annotation.configuration public class mainapp extends webmvcconfigureradapter implements webapplicationinitializer { @override public void onstartup(servletcontext sc) throws servletexception { // create 'root' spring application context annotationconfigwebapplicationcontext rootcontext = new annotationconfigwebapplicationcontext(); rootcontext.register(mainapp.class); // manage lifecycle of root application context sc.addlistener(new contextloaderlistener(rootcontext)); servletregistration.dynamic registration = sc.addservlet("dispatcher", new dispatcherservlet()); registration.setloadonstartup(1); registration.addmapping("/"); } @bean public viewresolver configureviewresolver() { internalresourceviewresolver viewresolve = new internalresourceviewresolver(); viewresolve.setprefix("/web-inf/"); viewresolve.setsuffix(".jsp"); homecoming viewresolve; } @bean public requestmappinghandlermapping requestmappinghandlermapping() { homecoming new requestmappinghandlermapping(); } @bean public requestmappinghandleradapter requestmappinghandleradapter() { homecoming new requestmappinghandleradapter(); } public static void main(string[] args) { springapplication.run(mainapp.class, args); } }

this controller:

@org.springframework.stereotype.controller public class controller { @requestmapping(value="/", method = requestmethod.get) public string index(){ homecoming "index"; } }

index.jsp within web-inf folders, , there nil within web.xml file. think far configuration right because can redirect /web-inf/index.jsp. however, think i'm missing configuration create application understand path. (/web-inf/index.jsp)

given you're using spring boot, configuration far more complicated needs be. boot automatically configure dispatcherservlet, viewresolver, requestmappinghandlermapping, , requestmappinghandleradapter you.

take @ spring boot's jsp sample see how little configuration need.

in add-on removing pretty much of manual configuration, 1 key difference main application class should extend springbootservletinitializer rather implementing spring's webapplicationinitializer directly. here's equivalent class in aforementioned sample:

package sample.jsp; import org.springframework.boot.springapplication; import org.springframework.boot.autoconfigure.enableautoconfiguration; import org.springframework.boot.builder.springapplicationbuilder; import org.springframework.boot.context.web.springbootservletinitializer; import org.springframework.context.annotation.componentscan; import org.springframework.context.annotation.configuration; @configuration @enableautoconfiguration @componentscan public class samplewebjspapplication extends springbootservletinitializer { @override protected springapplicationbuilder configure(springapplicationbuilder application) { homecoming application.sources(samplewebjspapplication.class); } public static void main(string[] args) throws exception { springapplication.run(samplewebjspapplication.class, args); } }

the main method used when launched war file using java -jar , configure method used when war deployed separate servlet container.

also note sample's utilize of application.properties configure view prefix , suffix.
