I am working on Spring MVC sample. when i use the / it works well. but when it comes to /xxx, it return WARNING. WARNING: No mapping found for HTTP request with URI [/SimpleSpringMVC/index] in DispatcherServlet with name 'report'

I had searched many answers, but all of them don't work well.

And here are details of my sample.

web.xml

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:tool.xml</param-value>
 </context-param>

 <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

 <servlet>
  <servlet-name>report</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>/WEB-INF/report-servlet.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
 </servlet>
  
   <servlet-mapping>
    <servlet-name>report</servlet-name>
    <url-pattern>/</url-pattern>
   </servlet-mapping>

  • I would guess tool.xml is not loaded at all as it is not included in web.xml. You can add multiple values under contextConfigLocation param-values by separating them with newlines. This way you can have multiple xml files for configuration. – Kaur Kase Nov 28 '14 at 08:54

Ok, i don' t know what is tool.xml for, but i would do something like this, put this line in report-servlet.xml <context:component-scan base-package="com.tian.controller" /> before <mvc:annotation-driven /> then in your web.xml put something like this : 

  <servlet>
        <servlet-name>report</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

 <servlet-mapping>
   <servlet-name>report</servlet-name>
   <url-pattern>/</url-pattern>
 </servlet-mapping>
  <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

And take a look at this controller, 

@Controller
@RequestMapping(value="/login")
public class LoginController {
    @RequestMapping(method=RequestMethod.POST)
    @ResponseBody
    public String receiveLoginRequest(@RequestParam String username,@RequestParam String password){
//DO WHAT YOU WANT
    }
}

And when you test a controller, localhost:8080/report/login/YOURMETHODMAP

  • thank you for your answer, i just put into report-servlet.xml, and it works well. but i wanna to know that the reason why i have to do it? since ContextLoaderListener is the root context, all child container, such as report-servlet.xml, share it. – Juntian Nov 29 '14 at 04:30
  • all controllers must in xxx-servlet.xml.http://stackoverflow.com/a/3652125/4302844 – Juntian Nov 29 '14 at 04:35

You want to understand how to config your context my friend so instead of giving you a botched answer that doesn't really help you, here is a beautiful answer : ANSWER BY informatik01, giving you a nice and simple lecture

Long story short web application contexts are hierarchical and your mapping is ignored (more or less)

Hope this helps.
