如何使用自定义WebApplicationInitializer运行测试？

Question

class MyWebAppInitializer extends WebApplicationInitializer {
  def onStartup(servletContext: ServletContext): Unit = {
      ...
  }
}

@RunWith(classOf[SpringJUnit4ClassRunner])
@WebAppConfiguration
@ContextConfiguration(classes = Array(classOf[MyConfig]),
    initializers=Array(classOf[MyWebAppInitializer]))     // <<< ERROR
class MyTest {
  ...
}

抱怨:

annotation argument needs to be a constant; found: classOf[MyWebAppInitializer] 

更新:@M.Deinum指出这里只允许ApplicationContextInitializers - 所以错误是一个报告错误的类型错误匹配.

那么......我怎样才能按顺序使用自己的MyWebAppInitializer并测试其中定义的功能？

在您的上下文配置中,我没有看到您列出了上下文加载器.该AnnotationConfigWebContextLoader将定位的情况下WebApplicationInitializer在classpath中,通过添加这一点,并移除intializers(正如你所指出的,是ApplicationContextInitializers而不是WebApplicationInitializers),那么你应该所有设置.

@RunWith(classOf[SpringJUnit4ClassRunner])
@WebAppConfiguration
@ContextConfiguration(classes = {ConfigClass.class, AnotherConfigClass.class}, loader=AnnotationConfigWebContextLoader.class))
class MyTest {
...

这是一个有效的例子

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes={WebConfiguration.class, SecurityConfig.class}, loader=AnnotationConfigWebContextLoader.class)
@ActiveProfiles("dev")
public class AppTests {
    private MockMvc mockMvc;

    @Autowired
    protected WebApplicationContext webApplicationContext;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void simple() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.view().name("index"));
    }
}
