2 天无法连接到远程 mongo 数据库

Question

我无法连接到远程 mongo 数据库。我在我的 pom 中使用了以下 spring 依赖项：

<dependency>
      <groupId>org.mongodb</groupId>
      <artifactId>mongo-java-driver</artifactId>
      <version>3.0.3</version>
  </dependency>

  <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-mongodb</artifactId>
      <version>1.7.1.RELEASE</version>
  </dependency>

我的数据库连接 xml 的相关部分是：

<mongo:mongo id="mongo" host="ds059702.mongolab.com" port="59702"  />
<mongo:db-factory
        id="mongoDbFactory"
        host="ds059702.mongolab.com"
        port="59702"
        username="XXX"
        password="XXX"
        dbname="test081142"
        mongo-ref="mongo"/>

mongo db 的版本是 2.6。我在连接（基本上是阅读）时遇到的异常是

org.springframework.data.mongodb.UncategorizedMongoDbException: Query failed with error code 13 and error message 'not authorized for query on test081142.Entity' on server ds059702.mongolab.com:59702; nested exception is com.mongodb.MongoQueryException: Query failed with error code 13 and error message 'not authorized for query on test081142.Entity' on server ds059702.mongolab.com:59702

原因：com.mongodb.MongoQueryException：服务器 ds059702.mongolab.com:59702

上的查询失败，错误代码 13 和错误消息 'not authorized for query on test081142.Entity'

我需要一些帮助来找出我到底在哪里犯了错误。我 100% 确定凭据是正确的。无法确定我们的确切问题。

--------------------更新------------------------ -----

我能够使用

连接并执行 CRUD

 MongoClientURI uri  = new MongoClientURI("mongodb://dbuser:XXXX@ds059702.mongolab.com:59702/test081142");
    MongoClient client = new MongoClient(uri);
    DB db = client.getDB(uri.getDatabase());

所以一定是我的 spring 配置有问题...

Answer 1

从错误消息来看，您连接到数据库的 "user" 似乎没有 'read' 角色。

必须通过（可能由您的数据库管理员）向用户授予角色：

use reporting
db.grantRolesToUser(
    "reportsUser",
    [
      { role: "read", db: "accounts" }
    ]
)

以上代码取自下面link :

http://docs.mongodb.org/manual/tutorial/manage-users-and-roles/#grant-a-role

Answer 2

我可以使用以下配置连接到远程 mongo 数据库：

<mongo:mongo-client id="mongo" host="ds059702.mongolab.com" port="59702" credentials="dbuser:XXXX@test081142" >
</mongo:mongo-client>
<mongo:db-factory
        id="mongoDbFactory"
        host="ds059702.mongolab.com"
        port="59702"
        username="dbuser"
        password="XXXX"
        dbname="test081142"
        mongo-ref="mongo" authentication-dbname="test081142"/>

在 spring-data 文档中没有写到这是使用 spring 配置连接到 mongo 数据库所需的语法。遗憾的是，spring-data 需要提供更清晰的配置语法。直接从 spring docs

中获取语法
