无法在使用SpringJUnit4ClassRunner的测试中加载Spring应用程序上下文

问题描述

我不知道为什么Spring无法在定义如下的测试类中加载应用程序上下文:

I can't figure out why Spring can't load the application context in a test class defined as follows:

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations={"/springMVC-config/mainController-servlet.xml"})
    public class DiagnosticsControllerTest {

    @Mock
    DiagnosticsService diagnosticsService;

    private DiagnosticsController diagnosticsController;

    private MockMvc mockMvc;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
        diagnosticsController = new DiagnosticsController();
        diagnosticsController.setService(diagnosticsService);
        this.mockMvc = MockMvcBuilders.standaloneSetup(diagnosticsController).build();
    }

    @Test
    public void shouldRun() {
        assertTrue(1 == 1);
    }
}

文件"mainController-servlet.xml"位于"myproject \ src \ main \ webapp \ WEB-INF \ springMVC-config \ mainController-servlet.xml"中

The file 'mainController-servlet.xml' is in "myproject\src\main\webapp\WEB-INF\springMVC-config\mainController-servlet.xml"

我得到的错误是:

我尝试如下更改上下文配置的位置:

I tried to change the locations for the context configuration as follows:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("file:src/main/webapp/WEB-INF/springMVC-config/mainController-servlet.xml")
public class DiagnosticsControllerTest {
...
}

推荐答案

除了无法引用XML配置文件的正确路径外，事实是:

Aside from not being able to reference the correct path to your XML configuration file, the truth is:

在您提供的示例中，您甚至没有使用 Spring TestContext Framework .

You are not even using the Spring TestContext Framework in the example you provided.

相反，您仅使用Mockito和Spring MVC测试(即MockMvc).

Rather, you are only using Mockito and Spring MVC Test (i.e., MockMvc).

因此，您可以简单地完全删除@RunWith和@ContextConfiguration声明.

Thus, you can simply delete the @RunWith and @ContextConfiguration declarations completely.
