Spring Boot Test,在配置中注入值

【中文标题】Spring Boot Test,在配置中注入值【英文标题】:SpringBoot Test, inject value in configuration 【发布时间】:2020-10-04 14:20:01 【问题描述】:我想做什么:
从测试容器https://github.com/testcontainers/testcontainers-spring-boot/tree/develop/embedded-mongodb启动MongoDB容器 将从已启动容器中获取的 MongoDB uri 注入到配置中 运行测试这是我的代码:
@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties =
"embedded.mongodb.install.enabled=true",
"spring.data.mongodb.uri=mongodb://$embedded.mongodb.host:$embedded.mongodb.port/$embedded.mongodb.database"
)
@AutoConfigureMockMvc
@ImportAutoConfiguration
class UploadFileControllerTest
@LocalServerPort
private int port;
@Autowired
private MockMvc mockMvc;
@Autowired
private ObjectMapper objectMapper;
private static MongoDBContainer mongoDbContainer;
@BeforeAll
public static void startContainer()
mongoDbContainer = new MongoDBContainer();
mongoDbContainer.start();
// !!! this one should be injected into spring.data.mongodb.uri
System.out.println("mongoURL: " + mongoDbContainer.getReplicaSetUrl());
// !!!
@AfterAll
public static void stopContainer()
mongoDbContainer.stop();
@Test
void testUploadAndParseFile() throws Exception
var fileUploadTask = uploadFileUsingMockMvc(zipFile);
System.out.println(fileUploadTask);
我找不到填充 spring.data.mongodb.uri
配置值的方法。
【问题讨论】:
查看baeldung.com/spring-boot-embedded-mongodb 我想要真正的 :) 【参考方案1】:当您使用 JUnit 5 时,您可以为 Testcontainers 使用 JUnit Jupiter 扩展,因此您不必手动启动和停止它们(如 JUnit 4 中的 @ClassRule
):
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>junit-jupiter</artifactId>
<version>$testcontainers.version</version>
<scope>test</scope>
</dependency>
如果您使用 Spring Boot >= 2.2.6,他们甚至使用 @DynamicPropertySource
简化了在测试中动态设置属性的方法。
如果将两者结合起来,您的测试可能如下所示:
// @ExtendWith(SpringExtension.class) not needed, already part of @SpringBootTest
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc
@ImportAutoConfiguration
@Testcontainers // this is new
class UploadFileControllerTest
@LocalServerPort
private int port;
@Autowired
private MockMvc mockMvc;
@Autowired
private ObjectMapper objectMapper;
@Container
private static MongoDBContainer mongoDbContainer = new MongoDBContainer();
@DynamicPropertySource
static void mongoDbProperties(DynamicPropertyRegistry registry)
registry.add("spring.data.mongodb.uri", mongoDbContainer::getUri);
@Test
void testStuffWithMongo() throws Exception
// bla-bla-bla
如果你使用的是 JUnit 4 或 Spring Boot 2.2.6 之前的版本,我收集了不同的设置方法here。

【参考方案2】:这是我的解决方案,因为它具有全局静态状态,所以有点味道,但至少可以工作
包装容器
public class MongoDbContainerEntryPoint
private static MongoDBContainer mongoDbContainer = new MongoDBContainer();
public static void start()
mongoDbContainer.start();
public static void stop()
mongoDbContainer.stop();
public static String getUri()
return mongoDbContainer.getReplicaSetUrl();
这个东西允许在测试实例化期间覆盖属性
public class MongoDBContextInitializer implements
ApplicationContextInitializer<ConfigurableApplicationContext>
@Override
public void initialize(ConfigurableApplicationContext ac)
ConfigurableEnvironment ce = ac.getEnvironment();
System.out.println("Setting to configuration: " + MongoDbContainerEntryPoint.getUri());
TestPropertyValues values = TestPropertyValues.of(
"spring.data.mongodb.uri=" + MongoDbContainerEntryPoint.getUri()
);
values.applyTo(ac);
这是测试
@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(initializers = MongoDBContextInitializer.class)
@AutoConfigureMockMvc
@ImportAutoConfiguration
class UploadFileControllerTest
@LocalServerPort
private int port;
@Autowired
private MockMvc mockMvc;
@Autowired
private ObjectMapper objectMapper;
@BeforeAll
public static void startContainer()
MongoDbContainerEntryPoint.start();
@AfterAll
public static void stopContainer()
MongoDbContainerEntryPoint.stop();
@Test
void testStuffWithMongo() throws Exception
// bla-bla-bla
