为什么我不断收到 "Failed to load ApplicationContext" 错误？
Why do I keep getting the "Failed to load ApplicationContext" error?
我已经实施了以下测试class：
import com.mongodb.BasicDBObjectBuilder;
import com.mongodb.DBObject;
import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.data.mongo.DataMongoTest;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit.jupiter.SpringExtension;
@DataMongoTest(properties = {"spring.mongodb.embedded.version=4.0.2"})
@ExtendWith(SpringExtension.class)
public class MyIntegrationTest {
@DisplayName("Test display name")
@Test
public void test(@Autowired MongoTemplate mongoTemplate) {
// given
DBObject objectToSave = BasicDBObjectBuilder.start()
.add("key", "value")
.get();
// when
mongoTemplate.save(objectToSave, "collection");
// then
Assertions.assertThat(mongoTemplate.findAll(DBObject.class, "collection")).extracting("key")
.containsOnly("value");
}
}
这与 Springs 文档中的完全相同，但是当我 运行 测试时，我不断收到以下错误：
java.lang.IllegalStateException: Failed to load ApplicationContext
和
2022-01-04 10:35:02 UTC | WARN | AnnotationConfigApplicationContext | Exception encountered during context

我做错了什么？我想要做的是使用嵌入式内存进行测试 MongoDB.
更新：
这是我的项目结构：
▼ src
▼ main
▼ java
▼ youben
YouBenApplication (Spring Boot Runnable Class)
▼ test
▼ java
▼ youben
MyIntegrationTest (this is the test class)
这是我的 运行nable class:
@SpringBootApplication
public class YouBenApplication {
public static void main(String[] args) {
SpringApplication.run(YouBenApplication.class, args);
}
}
这是错误信息：

我想你用过这个tutorial。
以下注释似乎是正确的
@DataMongoTest
@ExtendWith(SpringExtension.class)
然而，正如 spring doc for embedded mongo db 建议，您应该定义应该使用的嵌入式 mongo 数据库版本。
所以你应该将那些以前的注释配置为
@DataMongoTest(properties = {"spring.mongodb.embedded.version=4.0.2"})
@ExtendWith(SpringExtension.class)
例如，如果您需要版本 4.0.2
\
编辑:
要使 @ExtendWith 正常工作，您还必须在 main 目录中配置 spring 启动应用程序。仅使用 test 目录是不够的。
因此请确保您在 src/main/java/yourpackage 中有类似
的内容
@SpringBootApplication
public class ServiceLauncher {
public static void main(String[] args) {
SpringApplication.run(ServiceLauncher.class, args);
}
}
重要！测试也应该在同一个mypackage目录示例src/test/java/yourpackage
