我有一个使用 MongoDB 的 Spring Boot 应用程序。我想将嵌入式 FongoDB 用于我的 JUnit 测试。我关注一些文章，例如：
http://dontpanic.42.nl/2015/02/in-memory-mongodb-for-unit-and.html
我的 Fongo 测试配置看起来像
package com.myproject.rest;
import com.github.fakemongo.Fongo;
import com.mongodb.Mongo;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
@Profile("test")
@ComponentScan(basePackages = "com.myproject.service.data")
@EnableMongoRepositories(basePackages = "com.myproject.service.data.repository")
@Configuration
public class MongoTestConfig extends AbstractMongoConfiguration {
@Override
protected String getDatabaseName() {
return "demo-test";
}
@Bean
@Override
public Mongo mongo() {
return new Fongo("mongo-test").getMongo();
}
}
我对此有这种依赖性：
<dependency>
<groupId>com.github.fakemongo</groupId>
<artifactId>fongo</artifactId>
<version>2.1.0</version>
<scope>test</scope>
</dependency>
我想测试我的服务，它自动连接了一个扩展 MongoRepository 的存储库接口
package com.myproject.service.data.repository;
import com.myproject.service.data.entity.JournalData;
import org.springframework.data.mongodb.repository.MongoRepository;
import java.util.List;
public interface JournalRepository extends MongoRepository<JournalData, String> {
@Override
public List<JournalData> findAll(Iterable<String> ids);
}
我的测试类继承自以下类：
package com.myproject.rest;
import com.lordofthejars.nosqlunit.mongodb.MongoDbRule;
import cz.csas.services.commons.api.RequestMetadata;
import org.junit.Before;
import org.junit.Rule;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PowerMockIgnore;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import org.powermock.modules.junit4.PowerMockRunnerDelegate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.data.mongo.DataMongoTest;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.web.servlet.MockMvc;
import static org.mockito.Mockito.when;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
import static com.lordofthejars.nosqlunit.mongodb.MongoDbRule.MongoDbRuleBuilder.newMongoDbRule;
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
@PowerMockIgnore({"javax.xml.*", "org.xml.*", "org.w3c.*", "javax.management.*", "javax.net.ssl.*"})
@PrepareForTest({RequestMetadata.class})
@ActiveProfiles("test")
public class EndpointTestContext {
@Autowired
protected MockMvc mockMvc;
//@Rule
//public MongoDbRule mongoDbRule = newMongoDbRule().defaultSpringMongoDb("demo-test");
@Before
public void setup() {
mockStatic(RequestMetadata.class);
when(RequestMetadata.builder()).thenCallRealMethod();
RequestMetadata m = RequestMetadata.builder()
.workingMode("TEST")
.build();
when(RequestMetadata.getMetadata()).thenReturn(m);
}
}
但是当我运行 Maven 测试时，我收到以下信息：

谁能建议如何解决它？先感谢您。
