Spring 3.2.5 error “java.lang.AssertionError: No ModelAndView found” for all my controller Unit Test

问题

I'm trying to write some unit tests for my controllers in a Spring MVC and i have already error for my unit test : "java.lang.AssertionError: No ModelAndView found.

my app and conrollers works correcty.

Does anyone have any ideas ?

code controller :

@Controller
public class LoginController {
@RequestMapping(value="/loginfailed", method = RequestMethod.GET)
public String loginerror(ModelMap model) {
    model.addAttribute("error", "true");
    return "accueilLogin";

}
}

unit test :

ContextConfiguration(locations = { "classpath:/META-INF/applicationContext-test.xml" })
@WebAppConfiguration
public class LoginControllerTest extends AbstractJUnit4SpringContextTests {

@Autowired
private WebApplicationContext wac ;

private MockMvc mockMvc;

@Before
public void setup() {
    this.mockMvc = webAppContextSetup(this.wac).build();
    System.out.println(wac.getBeanDefinitionNames());

}
@Test
public void testLoginFailed() throws Exception {
    this.mockMvc.perform(get("/loginfailed")).andDo(print())
    .andExpect(view().name("accueilLogin"));
}

spring-security config :

    <intercept-url pattern="/accueilLogin*" access="ROLE_ANONYMOUS, ROLE_USER" />
    <intercept-url pattern="/register*" access="ROLE_ANONYMOUS, ROLE_USER" />
    <intercept-url pattern="/welcome*" access="ROLE_USER" />
    <!-- <intercept-url pattern="/logout*" access="ROLE_USER" /> -->
    <form-login login-page="/accueilLogin" default-target-url="/welcome"
        authentication-failure-url="/loginfailed" />
    <logout logout-success-url="/logout" />
</http>

web.xml config :

<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>

回答1:

Your logs are showing that you are getting a 404

Status = 404

which means that your handler is not being found.

I'm willing to bet that your @Controller isn't being registered. You've loaded your config like so

@ContextConfiguration(locations = { "classpath:/META-INF/applicationContext-test.xml" })

Does applicationContext-test.xml do a <component-scan> on the package that your controller is in? Does it do a <mvc:annotation-driven>? If it doesn't, then your application hasn't registered your handler method.
