春季啟動-嵌入式mongodb連接被拒絕

Question

在這個示例春季啟動項目中，我要測試MongoRepository持久層以及使用嵌入式mongodb使用存儲庫的Service類。 但是，我收到一個Connection refused: connect錯誤（ java.net.ConnectException ），請參閱下面的詳細堆棧跟蹤。

這是我的考試課

@RunWith(SpringRunner.class)
@SpringBootTest(classes=MongoConfig.class)
@TestPropertySource(locations = "classpath:application-test.properties")
public class Test_TimezoneDao {

    private static final Logger LOG = LoggerFactory.getLogger(Test_TimezoneDao.class);

    @Autowired private TimezoneDao dao;
    @Autowired private CounterService counterService;


    @Test
    public void test() 
    { /*...*/ }
}

使用此配置類

@Profile("test")
@SpringBootConfiguration
@ComponentScan(basePackages= {"com.example.demomongodb"})
@EnableMongoRepositories(basePackages= {"com.example.demomongodb"})
@EnableAutoConfiguration
@AutoConfigureDataMongo
public class MongoConfig 
{ }

為了讓春天使用我導入的嵌入式mongodb

       <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-data-mongodb</artifactId>
       </dependency>

        <dependency>
            <groupId>de.flapdoodle.embed</groupId>
            <artifactId>de.flapdoodle.embed.mongo</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>cz.jirutka.spring</groupId>
            <artifactId>embedmongo-spring</artifactId>
            <version>1.3.1</version>
            <scope>test</scope>
        </dependency>

並在application-test.properties配置

spring.profiles.active=test
# tried both random port (port=0) and deterministic port
spring.data.mongodb.port=27019
spring.data.mongodb.host=localhost
spring.data.mongodb.database=mongo-example

完整的錯誤是這樣的：

謝謝您的幫助！

編輯

還嘗試從所有應用程序屬性中刪除mongo主機和端口，相同的問題

編輯2

當我按照春季啟動文檔中的建議將mongodb端口更改為0時，我得到java.net.ConnectException: connect: Address is invalid on local machine, or port is not valid on remote machine 。 因此它確實嘗試使用端口0，並且不使用spring boot docs中所述的隨機端口。 這似乎根本不起作用。

我認為您也需要在mongo config中創建此bean。

@Bean(destroyMethod="close")
public Mongo mongo() throws IOException {
    return new EmbeddedMongoBuilder()
        .version("2.4.5")
        .bindIp("127.0.0.1")
        .port(12345)
        .build();
}
