java - 不再支持将 UserCredentials 与 MongoClient 一起使用

Question

我正在尝试将我的 spring boot 应用程序部署到 cloud foundry。但是我收到以下错误。

2016-02-19T16:54:29.57+0000 [App/0]      ERR Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: Usage of 'UserCredentials' with 'MongoClient' is no longer supported. Please use 'MongoCredential' for 'MongoClient' or just 'Mongo'.

据我所知，Spring Boot 会自动找到绑定(bind)的 Mongo 服务以及所有必要的用户凭据和 URI 详细信息，这意味着我不需要显式声明这些变量。

有谁知道我为什么会收到此错误以及我该如何解决它？

这是我的 Java 代码片段:

@Autowired
    public MongoRepository(MongoClient mongo) {
        this.mongo = mongo;
    }


public long insert(Document document){

    MongoDatabase db = mongo.getDatabase("test");
    MongoCollection<Document> coll = db.getCollection("document");
    coll.insertOne(document);
}

我使用的是Mongo3.0 java驱动。

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongo-java-driver</artifactId>
    <version>3.0.0</version><!--$NO-MVN-MAN-VER$-->
</dependency>

我没有使用 Spring Boot，但我也遇到了这个错误。我通过使用以下配置解决了这个问题:

@Configuration
public class SpringMongoConfig {

    public @Bean MongoClient mongoClient() {
        return new MongoClient(new ServerAddress("127.0.0.1", 27017), new ArrayList<MongoCredential>() {

            {
                add(MongoCredential.createCredential("username", "dbname", "pwd".toCharArray()));
            }
        });
    }

    public @Bean MongoDbFactory mongoDbFactory() throws Exception {
        return new SimpleMongoDbFactory(mongoClient(), "dbname");
    }

    public @Bean MongoTemplate mongoTemplate() throws Exception {
        MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());
        return mongoTemplate;
    }

}
