无法从Spring Boot连接到Dockerized MongoDb实例

Question

我有一个停靠的MongoDB实例。我正试图让Spring Boot连接到它，但在启动Spring Boot时，我收到了一条错误消息。

请在下面找到详细信息。

错误消息：

Spring Boot应用程序中的application.properties:

spring.data.mongodb.uri=mongodb://localhost:27017/airbnb-data
spring.data.mongodb.port=27017
spring.data.mongodb.database=airbnb-data
spring.data.mongodb.host=localhost
spring.data.mongodb.username=mongodbuser
spring.data.mongodb.password=mongodbpwd

启动MongoDB实例的docker-compose.yml：

DataConfig类：

@Configuration
public class DatabaseConfig extends AbstractMongoConfiguration {
@Value("${spring.data.mongodb.myuri}")
private String mongoDbUrl;
@Value("${spring.data.mongodb.port}")
private String port;
@Value("${spring.data.mongodb.database}")
private String mongoDbName;
/**
* Url to mongo db
* 
* @return a string representing the url of bdd
* @throws MalformedURLException
*/

@Override
public MongoClient mongoClient() {
return new MongoClient(this.mongoDbUrl, Integer.parseInt(this.port));
}


@Override
public @Bean MongoTemplate mongoTemplate() throws Exception {
MappingMongoConverter converter = new MappingMongoConverter(new DefaultDbRefResolver(mongoDbFactory()),
new MongoMappingContext());
converter.setMapKeyDotReplacement("\+");
MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory(), converter);
return mongoTemplate;
}
@Override
protected String getDatabaseName() {
return this.mongoDbName;
}
/**

* @return link to db
* @throws Exception
*
* @Bean public MongoTemplate accessBddMongo() throws Exception { return new
*       MongoTemplate(bddGetEndpointUrl(), mongoDbName); }
*/
}

感谢您的帮助

我意识到我不需要在DataConfig类中设置mongoClient((方法。修改后，我有：

@Override
public MongoClient mongoClient() {
return new MongoClient();
}

已解决
