如何使用@PathVariable对Spring MVC控制器进行单元测试？
如何使用@PathVariable对Spring MVC控制器进行单元测试？
提问于 2009-09-09 18:02:01
我有一个简单的带注释的控制器，类似于这个：
@Controller
public class MyController {
@RequestMapping("/{id}.html")
public String doSomething(@PathVariable String id, Model model) {
// do something
return "view";
}
}我想用这样的单元测试来测试它：
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
}
}问题是AnnotationMethodHandlerAdapter.handler()方法抛出了一个异常：
java.lang.IllegalStateException: Could not find @PathVariable [id] in @RequestMapping
at org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter$ServletHandlerMethodInvoker.resolvePathVariable(AnnotationMethodHandlerAdapter.java:642)
at org.springframework.web.bind.annotation.support.HandlerMethodInvoker.resolvePathVariable(HandlerMethodInvoker.java:514)

从Spring3.2开始，有一种合适的方法来测试它，以一种优雅而简单的方式。您将能够这样做：
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("servlet-context.xml")
public class SampleTests {
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = webAppContextSetup(this.wac).build();
}
@Test
public void getFoo() throws Exception {
this.mockMvc.perform(get("/foo").accept("application/json"))
.andExpect(status().isOk())
.andExpect(content().mimeType("application/json"))
.andExpect(jsonPath("$.name").value("Lee"));
}

在根据Spring参考手册中的术语进行集成测试后，我会这样称呼您。不如这样做：
import static org.springframework.test.web.ModelAndViewAssert.*;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({/* include live config here
e.g. "file:web/WEB-INF/application-context.xml",
"file:web/WEB-INF/dispatcher-servlet.xml" */})
public class MyControllerIntegrationTest {
@Inject
private ApplicationContext applicationContext;
private MockHttpServletRequest request;
private MockHttpServletResponse response;
private HandlerAdapter handlerAdapter;
private MyController controller;
@Before
public void setUp() {
request = new MockHttpServletRequest();
response = new MockHttpServletResponse();
handlerAdapter = applicationContext.getBean(HandlerAdapter.class);
// I could get the controller from the context here
controller = new MyController();
}
@Test
public void testDoSomething() throws Exception {
request.setRequestURI("/test.html");
final ModelAndView mav = handlerAdapter.handle(request, response,
controller);
assertViewName(mav, "view");
// assert something
}
}为了获得更多信息，我编写了一个blog entry about integration testing Spring MVC annotations。
