I'm trying to use MappingJacksonJsonView with Spring 3.0, without success. I don't know what I'm doing wrong, I think the problem is that I don't know how to tell to use the MappingJacksonJsonView to render a request. I tried to use the same name for view name and bean name of MappingJacksonView, but didn't work. I built a sample test application here:
https://github.com/stivlo/restjson
In web.xml I've defined ContextLoaderListener and the mapping for dispatcherServlet.
In servlet-context.xml I've added
and
In org.obliquid.restjson.web.ToDoList.java I set the logical view name as jsonView.
However, instead of using MappingJacksonJsonView, it looks for a JSP file, according to my JSP mapping.
message /restjson/WEB-INF/jsp/jsonView.jsp
description The requested resource (/restjson/WEB-INF/jsp/jsonView.jsp)
is not available.
What should I change to use MappingJacksonJsonView as a renderer?
UPDATE 1: In following tests I've found that if I add the following to my servlet-context.xml, JSON rendering works, but my other view, rendered as JSP (home) is not working anymore.
<!-- Resolve views based on string names -->
UPDATE 2: I removed the BeanNameViewResolver and changed my ToDoList.java to return directly the Collection to be converted in JSON, instead of ModelAndView, with a @ResponseBody annotation, as follows:
@RequestMapping("/toDoList")
public @ResponseBody List test() {
List toDoList = new ArrayList();
toDoList.add(new ToDoItem(1, "First thing, first"));
toDoList.add(new ToDoItem(1, "After that, do the second task"));
return toDoList;
}
In this way it works. Even though the mapping is even more "magical". It makes me wonder, if a similar renderer exists for XML for instance, how does Spring know which renderer to pick?
