Spring Controller not being called for expected URL

Question

I am trying to build a SpringMVC application and try to invoke a controller. it is giving me an error of java.io.FileNotFound Exception. Application is built with a RootContext value 'springmvc' and installed on Websphere 9

URL being invoked to hit controller -

http://localhost:9080/springmvc/logon

and this URL is giving a filenotFound for ' /logon.' But, at the same time http://localhost:9080/springmvc/ gets tied with Controller and giving the output as 'Hello World'. I am not sure on why /logon is not being recognized.

I have tried by keeping URL Pattern in web.xml as /springmvc/ or /springmvc/* but they all are not working. I have tried giving complete path in Controllers too.

Controller '''

 ` @Controller
public class AdminController{

@RequestMapping(value="/logon" , method = RequestMethod.GET)
@ResponseBody
public String config(){
system.out.println("Inside Config Method");
return "Hello World!";
} ` 

'''

Web.xml

`

<servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/todo-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/springmvc/*</url-pattern>
</servlet-mapping> ` 

todo-servlet.xml -

` <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

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

    <mvc:annotation-driven />

</beans>` 

I expect http://localhost:9080/springmvc/logon to return the response from AdminController class. Kindly suggest what am i missing or what url-pattern shouuld i try?

Answer 1

Assuming that AdminController is on the springmvc.com.controller package. The problem I see is the url-pattern, In this case the logon is expected on the path: http://localhost:9080/springmvc/springmvc/logon

The first one (springmvc) is the context of the application, all points start on it. The second is inside your application.

You need to define / to get the expected result.
