I have NetBeans Spring MVC project without any pom.xml file. I included jackson-databind-2.7.0-rc1.jar, jackson-core-2.7.0-rc1.jar and jackson-annotation-2.7.0-rc1.jar. But I got the following error pressing the button "Click me": HTTP Status 404 - Not Found. How can I avoid this error?
Here are my files

@Controller
public class Example {
class Test
{
final int id;
final String fio;
public Test(int id, String fio) {
this.id = id;
this.fio = fio;
}
public int getId() {

}
@RequestMapping(value = "/ls-test", method = RequestMethod.GET,
produces = {MediaType.APPLICATION_JSON_VALUE})
public ResponseEntity <Test> test()
{
Test t = new Test(1, "123");
return new ResponseEntity<Test>(t, HttpStatus.OK);
}
@RequestMapping(value = "/index", method = RequestMethod.GET)
public ModelAndView loadIndex()
{
ModelAndView mv = new ModelAndView();
mv.setViewName("index");
return mv;
}
}
I have the same error when I chante method test() by the following code:
@RequestMapping(value = "/ls-test", method = RequestMethod.GET,
produces = {MediaType.APPLICATION_JSON_VALUE})
public @ResponseBody Test test()
{
Test t = new Test(1, "123");
return t;
}
