java - Spring MVC 测试配置

标签 java unit-testing spring-mvc spring-mvc-test

我正在进入 Spring MVC 测试框架，但无法使其工作。 当我尝试开始测试时，得到这个:

java.lang.IllegalStateException: Failed to load ApplicationContext

    at org.hibernate.cfg.beanvalidation.TypeSafeActivator.getValidatorFactory(TypeSafeActivator.java:463)

Process finished with exit code -1

这是我的测试类:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("controller-test-context.xml")
public class ProjectControllerTest {

@Autowired
private WebApplicationContext webApplicationContext;

private MockMvc mockMvc;

@Autowired
private UserService userService;

@Autowired
private ProjectService projectService;

@Autowired
private CustomerService customerService;

@Autowired
private ConsultantService consultantService;

@Autowired
private PartnerService partnerService;

private User user;
private Model model;
private Project project;

private ProjectController projectController;

@Before
public void setup() {
    Mockito.reset(userService);
    Mockito.reset(projectService);
    Mockito.reset(customerService);
    Mockito.reset(consultantService);
    Mockito.reset(partnerService);

    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}

@Test
public void addProjectPageExt() throws Exception {

    mockMvc.perform(get("/projects"))
            .andExpect(status().isOk())
            .andReturn();
}

这里是测试上下文 xml (controller-test-context.xml):

更新

添加 EL 实现后，我得到另一个异常(考虑到当应用程序启动时，加载 jdbc 驱动程序没有问题，仅在测试中):

最佳答案

异常的根本原因是:

Caused by: java.lang.ClassNotFoundException: com.sun.el.ExpressionFactoryImpl

找不到该类的原因可能是因为您缺少提供该类的依赖项。将以下内容添加到 POM 文件中:

<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>el-impl</artifactId>
    <version>2.2</version>
    <scope>test</scope>
</dependency>
