【问题描述】：

我想使用 Controller 和 Repository 创建带有 Spring Boot 上下文配置的完整 JUnit 测试。我的测试类如下所示：

@RunWith(SpringRunner.class)
@SpringBootTest
//@WebAppConfiguration
@DataJpaTest
@AutoConfigureTestDatabase(replace= AutoConfigureTestDatabase.Replace.NONE)
public class ControllerTest {

    @Autowired
    UserController userCtrl;

    @Autowired
    private WebApplicationContext ctx;

    private MockMvc mockMvc;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
    }

    @Test
    public void loginTest() throws Exception {
        //mockMvc.perform(get("/")).andExpect(status().isOk());

    }
}

我有标准的用户实体、UserController 和 UserRepository。我在 application.properties 中配置了我的数据源，但我无法同时运行 @SpringBootTest 和 @DataJpaTest。这是错误信息：

欢迎使用 stackoverflow，请使用 tour，并特别阅读 here 中的“如何创建最小、完整且可验证的示例”。发布 MCVE 问题很可能会获得更快、更有用的回复。
@razyel8，你能发布你的 Spring Boot 的主类吗？
您要么想测试整个 Boot 应用程序，要么测试它的一部分。 DataJpaTest、WebMvcTest 和 JsonTest 用于测试应用程序切片，SpringBootTest 用于测试整个应用程序。不要把它们混在一起
我想测试整个应用程序。但是当我删除 @DataJpaTest 我的数据库无法正常工作。然后我得到了：java.lang.IllegalStateException: Failed to load ApplicationContext Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: EmbeddedDatabaseType is required Caused by: java.lang.IllegalArgumentException: EmbeddedDatabaseType is required

【解决方案1】：

好的，我想通了。测试类应该是这样的：

@RunWith(SpringRunner.class)
@SpringBootTest
@WebAppConfiguration
public class ControllerTest {

    @Autowired
    UserController userCtrl;

    @Autowired
    public UserRepository userDao;

    @Autowired
    private WebApplicationContext ctx;

    private MockMvc mockMvc;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
    }

    @Test
    public void loginTest() throws Exception {

        User user1 = new User();
        user1.setEmail("adres@email.com");
        user1.setPassword("12345");
        userDao.save(user1);

        mockMvc.perform(post("/user/login")
                .param("email", "adres@email.com")
                .param("password", "12345"))
                .andExpect(status().isOk());

    }
}

现在它正在对数据库执行测试并处理请求。一开始是不行的，因为我还在其他类中混合了@DataJpaTest和@SpringBootTest注解
