Spring ajax request

Question

I have a spring 3.1 web application and I am trying to execute an ajax request, but in firebug I see that my mapping was not found. I tried different things, but can't just get to my controller method. Here are a few details:

I have my my web.xml:

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/ctrl/*</url-pattern>
</servlet-mapping>

this is in my controller:

@RequestMapping(value="/ctrl/test", method = RequestMethod.GET)
public @ResponseBody String test() {
    System.out.println("method test()");
    return "aString";
}

this is in my manager-servlet.xml:

<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/pages/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

I have another request mapped to a method in my controller and that it works, but it is not ajax:

@RequestMapping(value="/ctrl", method = RequestMethod.GET)
public String printWelcome(ModelMap model, HttpSession session) {
    initializeTree(session);
    return "tree";
}

Can anyone point me in the right direction?

Answer 1

I found a solution:

in my web.xml:

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/ctrl/*</url-pattern>
</servlet-mapping>

in my controller:

@RequestMapping(value="/test", method = RequestMethod.GET)
public String test(ModelMap model, HttpSession session) {
    System.out.println("method test()");
    return null;
}

On the client side, I use jQuery:

$.get(
     "ctrl/test/",
     function(data){
         alert(data);
});

I can build on that; my System.out.println is printing, so now I can contact my controller.

ajax *.action *.ajax AJAX *.html jsp. -

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>*.ajax</url-pattern>
    </servlet-mapping>
<servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>

next :

URI- ajax /ctrl, :

@Controller
@RequestMapping(value="/ctrl")
public class AjaxController{

@RequestMapping(value="/test.ajax", method = RequestMethod.GET)

public String test(ModelMap model, HttpSession session) {
    System.out.println("method test()");
    return "test";

}
}

@ResponseBody ajax.

index.html :

@Controller
public class ViewController{

@RequestMapping(value="/index.html", method = RequestMethod.GET)
@ResponseBody
public String test(ModelMap model, HttpSession session) {
    System.out.println("method test()");
    return "index";

}
}
