找不到映射错误Spring MVC

Question

I made a very simple Spring MVC application to learn AOP, yet each time I try to navigate any of the application pages, I get (No mapping found) error as follows:

No mapping found for HTTP request with URI [/TestAOP/page1.htm] in DispatcherServlet with name 'appServlet'

I've doubled checked web.xml, servlet-context.xml, controller code but couldn't notice anything wrong. So I will appreciate it so much if someone can please look at the content of my web.xml, servlet-context.xml and controller and let me know what I am missing here and how I can overcome this error. Thanks for your time

1. Web.xml

     <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/root-context.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> 

2. servlet-context.xml

  <annotation-driven /> <context:component-scan base-package="com.sampledomain.app.controller" /> <aop:aspectj-autoproxy/> <resources mapping="/resources/**" location="/resources/" /> <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <beans:property name="prefix" value="/WEB-INF/views/" /> <beans:property name="suffix" value=".jsp" /> </beans:bean> 

1. Controller

    @Controller public class HomeController { @RequestMapping(value = "/page1", method = RequestMethod.GET) public String firstPage(HttpServletRequest request,Locale locale, Model model) { Date date = new Date(); DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale); String formattedDate = dateFormat.format(date); model.addAttribute("serverTime", formattedDate ); return "page01"; } } 

2. root-context.xml Is mainly empty

Note: page01.jsp is under /WEB-INF/views/ folder

Answer 1

I would suggest to double check whether the Controller is instantiated by spring. The easiest way is to create an empty constructor with a sysout("my controller has been instantiated!!!") or whatever and lets see whether this line is in the catalina.out. Take a look whether

<context:component-scan base-package="com.sampledomain.app.controller" />

this is the correct package of your controller. If your controller is not instantiated by spring than double check also the spring config paths etc.

Answer 2

Try to remove the .htm from the URL. That is: http://[server][:port]/TestAOP/page1.

That should match the mapping on your controller.
