How to unit test a Spring MVC controller using @PathVariable?
- by Martiner
I have a simple annotated controller similar to this one:
@Controller
public class MyController {
@RequestMapping("/{id}.html")
public String doSomething(@PathVariable String id, Model model) {
// do something
return "view";
}
}
and I want to test it with an unit test like this:
public class MyControllerTest {
@Test
public void test() {
MockHttpServletRequest request = new MockHttpServletRequest();
request.setRequestURI("/test.html");
new AnnotationMethodHandlerAdapter()
.handle(request, new MockHttpServletResponse(), new MyController());
// assert something
}
}
The problem is that AnnotationMethodHandlerAdapter.handler() method throws an exception:
java.lang.IllegalStateException: Could not find @PathVariable [id] in @RequestMapping
