如何在 Spring Boot 集成测试中使用嵌入式 MongoDB

Question

我正在尝试使用 EmbeddedMongoDB 进行测试。

这是我的代码：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = {MyWebServiceApplication.class, TestMongoConfig.class})
public class MyWebServiceApplicationTests {

@Autowired 
InfoRepository repository;

@Before
public void setUp() {

}

@Test
public void setsIdOnSave() {
    Info dave = repository.findInfoByMobileNumber(917900);
    assertThat(dave.getCarrier(), is(notNullValue()));
    }
}

如果我删除 TestMongoConfig.class，测试可以工作，但它正在连接到实时数据库。

这是 TestMongoConfig 类。 I got this code here

@Configuration
public class TestMongoConfig {

@Autowired
private MongoProperties properties;

@Autowired(required = false)
private MongoClientOptions options;

@Bean(destroyMethod = "close")
public Mongo mongo(MongodProcess mongodProcess) throws IOException {
    Net net = mongodProcess.getConfig().net();
    properties.setHost(net.getServerAddress().getHostName());
    properties.setPort(net.getPort());
    return properties.createMongoClient(this.options);
}

@Bean(destroyMethod = "stop")
public MongodProcess mongodProcess(MongodExecutable mongodExecutable) throws IOException {
    return mongodExecutable.start();
}

@Bean(destroyMethod = "stop")
public MongodExecutable mongodExecutable(MongodStarter mongodStarter, IMongodConfig iMongodConfig) throws IOException {
    return mongodStarter.prepare(iMongodConfig);
}

@Bean
public IMongodConfig mongodConfig() throws IOException {
    return new MongodConfigBuilder().version(Version.Main.PRODUCTION).build();
}

@Bean
public MongodStarter mongodStarter() {
    return MongodStarter.getDefaultInstance();
}

}

现在，我收到此错误：

Could not autowire field: private org.springframework.boot.autoconfigure.mongo.MongoProperties com.example.TestMongoConfig.properties

请注意，我的应用程序连接到两个不同的 MongoDB 实例。我的“实时”连接配置没有使用自动配置，它有自己的 bean。 Here's my reference for achieving this.

Answer 1

@Configuration
@EnableAutoConfiguration
@EnableMongoRepositories(basePackages = { "package1", "package2" })
public class TestMongoConfig {

@Autowired
private MongoProperties properties;

@Autowired(required = false)
private MongoClientOptions options;

@Bean(destroyMethod = "close")
public Mongo mongo(MongodProcess mongodProcess) throws IOException {
    Net net = mongodProcess.getConfig().net();
    properties.setHost(net.getServerAddress().getHostName());
    properties.setPort(net.getPort());
    return properties.createMongoClient(this.options);
}

@Bean(destroyMethod = "stop")
public MongodProcess mongodProcess(MongodExecutable mongodExecutable) throws IOException {
    return mongodExecutable.start();
}

@Bean(destroyMethod = "stop")
public MongodExecutable mongodExecutable(MongodStarter mongodStarter, IMongodConfig iMongodConfig) throws IOException {
    return mongodStarter.prepare(iMongodConfig);
}

@Bean
public IMongodConfig mongodConfig() throws IOException {
     return new MongodConfigBuilder().version(Version.Main.PRODUCTION)
            .cmdOptions(new MongoCmdOptionsBuilder().useNoJournal(true)
                    .useStorageEngine("mmapv1")
         .build())
            .build(); 
}

@Bean
public MongodStarter mongodStarter() {
    return MongodStarter.getDefaultInstance();
}

}

@EnableAutoConfiguration 和 @EnableMongoRepositories(basePackages = { "package1", "package2" }) 需要在那里。我猜这就是 Spring Boot 将嵌入式 MongoDB 集成到它的 CrudRepository 中的方式

接下来是这段代码：

     return new MongodConfigBuilder().version(Version.Main.PRODUCTION)
            .cmdOptions(new MongoCmdOptionsBuilder().useNoJournal(true)
                    .useStorageEngine("mmapv1")
         .build())
            .build();

这是我在 32 位机器上运行的代码。我必须设置 mmapv1 并设置 useNoJournal 来修复 无法启动进程：EOF 错误。

对于错误

Could not autowire field: private org.springframework.boot.autoconfigure.mongo.MongoProperties com.example.TestMongoConfig.properties

我必须创建一个 application.properties，其中包含我在主要代码中的相同内容。
