具有凭据的Spring MongoDB XML配置失败

Question

我尝试连接到Cloudbees和MongoLab数据库（使用凭据）。我已在命令行上测试了凭据并验证了它们是否正确。

此外，当我通过注释定义MongoDbFactory时，我能够毫无问题地执行mongo操作，但是当我尝试XML配置路由时，没有这样的运气。

这是我的配置的一个版本：

<context:property-placeholder location="classpath:domain.properties"/>

<context:annotation-config />

<context:component-scan base-package="com.undisclosed" />

<mongo:repositories base-package="com.undisclosed.repository" />

<mongo:mongo host="${mongo.host}" port="${mongo.port}" />

<bean id="mongoCredentials" class="org.springframework.data.authentication.UserCredentials">
    <constructor-arg name="username" value="${mongo.user}" />
    <constructor-arg name="password" value="${mongo.pass}" />
</bean>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate" 
    c:mongo-ref="mongo" c:databaseName="${mongo.db}" c:userCredentials-ref="mongoCredentials">
</bean>

和另一个     

<context:annotation-config />

<context:component-scan base-package="com.undisclosed" />

<mongo:repositories base-package="com.undisclosed.repository" />

<mongo:db-factory dbname="${mongo.db}" password="${mongo.pass}" username="${mongo.user}" port="${mongo.port}" host="${mongo.host}"/>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
</bean>

我还验证了这些值实际上是从属性文件中获取的，因此这不是问题。您可以通过堆栈跟踪看到它正在尝试连接并提供凭据但无济于事。有没有人解决过这个问题？

堆栈追踪：

在盯着这个问题已经太久了之后，我可能会遗漏一些非常基本的东西。感谢。

以防其他人遇到此问题...我使用的是spring-data-mongodb版本1.2.1-RELEASE。我升级到1.3.0.M1（目前是最近的里程碑版本），问题就消失了。

就像一个FYI ......我在写入设置为FSYNC_SAFE的writeConcern时遇到了问题：

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongo" ref="mongo"/>
    <constructor-arg name="databaseName" value="${mongo.db}"/>
    <constructor-arg name="userCredentials" ref="mongoCredentials"/>
    <property name="writeConcern" value="FSYNC_SAFE"/>
</bean>

因此我将其更改为以下内容并最终正常工作：

<property name="writeConcern">  
    <util:constant static-field="com.mongodb.WriteConcern.NORMAL" />  
</property>  

希望这可以节省一些悲伤：）
