java - 使用 WebApplicationContext 的最低配置

Question

我有这个测试类的代码:

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@WebAppConfiguration
public class CandidateControllerTest {

    @Autowired
    WebApplicationContext wac;

    MockMvc mockMvc;

    @Before
    public void before() {
         mockMvc = MockMvcBuilders.webApplicationContextSetup(wac).build();

    }
...
}

执行上面的代码后，我看到以下跟踪:

我认为classpath:/test/BeanConfig.xml有问题。

我不知道需要在此文件中写入什么才能正确工作。

你能解释一下正确执行这段代码的最低条件吗？

您没有使用 Spring 运行测试类，而是使用普通的 Junit 运行。您需要使用 Spring 的测试运行器，否则 @Autowired 毫无意义，并且该字段仍为 null。

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
public class CandidateControllerTest {
