how does internalresourceviewresolver work?

how does internalresourceviewresolver work, when my controller class does not return a modelandview object? how does it map to views?

here is the code snippet from the controller class:

@RequestMapping(value = "/abc", method = RequestMethod.GET)
public @ResponseBody
List<Map<String, Object>> getabc() 
{
    return jdbcDa.abc();
}

and here is the code snippet from dispatcher servlet:

<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
<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>

Your method was annotated by @ResponseBody, so the method will convert the List<Map<String, Object>> to JSON, and wouldn't map to the view.

If you want to map the date to view, you can use AJAX request date from this interface @RequestMapping(value = "/abc", method = RequestMethod.GET), and use Javascript to show the date on the view. Just like this fragment:

$.getJSON('/abc', function (date) {
     var s = "";
     $.each(date, function (i, obj) {
          //use javascript to add date to variable s
     });
     //add s to view element
     $("#tag-list").append(s);
});

The internal view resolver is not involved here, you have annotated with @ResponseBody and the method does not return a string/view name.

The returned data doesn't get mapped to a view. It is converted to json or xml depending on the content type of original request.

A method annotated with @ResponseBody would normally be called asynchronously using javascript, the returned data would then, in a web app, be added to a specific part of the dom.
