Spring Aspect没有在单元测试中触发
好的,我们正在谈论Spring(3.2.0)MVC
我们定义了一个切入点,以在注释周围“触发”,如下所示:
@Around("@annotation(MyAnnotation)")public void someFunction() {
}
然后在控制器中,我们有:
@Controller@Component
@RequestMapping("/somepath")
public class MyController {
@Autowired
private MyService service;
...
@MyAnnotation
@RequestMapping(value = "/myendpoint", method = RequestMethod.POST, produces = "application/json")
@ResponseBody
public Object myEndpoint(@RequestBody MyRequestObject requestObject, HttpServletRequest request, HttpServletResponse response) {
...
return service.doSomething(requestObject);
}
}
然后我们有一个如下的单元测试:
@RunWith(SpringJUnit4ClassRunner.class)@WebAppConfiguration
@ContextConfiguration(locations = {"../path/to/applicationContext.xml"})
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class})
public class MyControllerTest {
private MockMvc mockMvc;
@InjectMocks
private MyController controller;
@Mock
private MyService myService;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
}
@Test
public void myTest() {
MyRequest request = new MyRequest();
MyResponse response = new MyResponse();
String expectedValue = "foobar";
Mockito.when(myService.doSomething((MyRequest) Mockito.any())).thenReturn(response);
MockHttpServletRequestBuilder builder = MockMvcRequestBuilders.post("/myendpoint");
String request = IOUtils.toString(context.getResource("classpath:/request.json").getURI());
builder.content(request);
builder.contentType(MediaType.APPLICATION_JSON);
mockMvc.perform(builder)
.andExpect(MockMvcResultMatchers.status().isOk())
.andExpect(MockMvcResultMatchers.jsonPath("$.someKey").value(expectedValue));
Mockito.verify(myService, Mockito.times(1)).doSomething((MyRequest) Mockito.any());
}
}
该测试运行良好,但是围绕注释(MyAnnotation)定义的方面未执行。当端点由 实际
请求触发时(例如,在servlet容器中运行时),这执行得很好,但在测试中运行时,则不会触发。
这是MockMvc的特定“功能”,它不会触发方面吗?
仅供参考,我们的applicationContext.xml配置为:
<aop:aspectj-autoproxy/>
正如我所提到的,这些方面实际上是在现实中起作用的,只是在测试中没有。
有谁知道如何激发这些方面的?
谢谢!

好的..所以解决方案最终是由您自己提出的..您猜对了..阅读文档:/
http://docs.spring.io/spring-framework/docs/3.2.0.BUILD-
SNAPSHOT/reference/htmlsingle/#spring-mvc-test-
framework
此外,您可以通过Spring配置将模拟服务注入到控制器中,以便专注于测试Web层。
因此,最终的解决方案如下所示:
@RunWith(SpringJUnit4ClassRunner.class)@WebAppConfiguration
@ContextConfiguration(locations = {"testContext.xml","../path/to/applicationContext.xml"})
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class})
public class MyControllerTest {
private MockMvc mockMvc;
@Autowired
private WebApplicationContext wac;
@Autowired
private MyService myService;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
@Test
public void myTest() {
MyRequest request = new MyRequest();
MyResponse response = new MyResponse();
String expectedValue = "foobar";
Mockito.when(myService.doSomething((MyRequest) Mockito.any())).thenReturn(response);
MockHttpServletRequestBuilder builder = MockMvcRequestBuilders.post("/myendpoint");
String request = IOUtils.toString(context.getResource("classpath:/request.json").getURI());
builder.content(request);
builder.contentType(MediaType.APPLICATION_JSON);
mockMvc.perform(builder)
.andExpect(MockMvcResultMatchers.status().isOk())
.andExpect(MockMvcResultMatchers.jsonPath("$.someKey").value(expectedValue));
Mockito.verify(myService, Mockito.times(1)).doSomething((MyRequest) Mockito.any());
}
}
然后,您只需为此测试定义一个上下文文件,testContext.xml
其中包含服务对象的模拟:
<bean id="myService" class="org.mockito.Mockito" factory-method="mock"> <constructor-arg value="com.mypackage.MyService"/>
</bean>
重要的是,MyService实例已@Autowired
进入测试,因此可以进行编排。
这允许您模拟出您喜欢的任何实例,无论它们是否在服务类,方面等中,只要您适当地命名Bean。因此,在这种情况下,MyService
将声明为:
@Component("myService")public class MyService {
...
