为了学习（spring/mongoBD/CLoudBees），我在 CloudBees 上创建了一个 mongoDB 实例，我正在尝试使用 spring Data 连接我的 spring 应用程序。

我收到以下错误：

我的 Spring Data 的 XML 配置：

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongo" ref="mongo"/>
    <constructor-arg name="databaseName" value="appDB"/>
    <constructor-arg name="userCredentials" ref="mongoCredentials"/>
</bean>

<bean id="mongoCredentials" class="org.springframework.data.authentication.UserCredentials">
     <constructor-arg name="username" value="#{mongoUri.username}" />
    <constructor-arg name="password" value="#{new java.lang.String(mongoUri.password)}" />
</bean>

<bean id="mongoUri" class="com.mongodb.MongoURI">
  <constructor-arg value="mongodb://MY_DB_USERNAME:MY_DB_PASS@paulo.mongohq.com:10048/xxxxxxxxxxxxx"/>
</bean>

<bean class="com.mongodb.Mongo" id="mongo">
    <constructor-arg ref="mongoUri" />
</bean>

当我使用 umongo 测试我的 URI mongodb://MY_DB_USERNAME:MY_DB_PASS@paulo.mongohq.com:10048/xxxxxxxxxxxxx 时，它连接正确。

Maven依赖：

spring data mongodb 版本：1.3.1.RELEASE
mongodb驱动版本：2.10.1
弹簧芯版本：3.2.3.RELEASE

知道我做错了什么吗？

我通过用#{mongoUri.database} 替换我的数据库名称“appDB”解决了这个问题，所以 mongoTemplate 的新 Bean def 是：

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongo" ref="mongo"/>
    <constructor-arg name="databaseName" value="#{mongoUri.database}"/>
    <constructor-arg name="userCredentials" ref="mongoCredentials"/>
</bean>

我不明白为什么将数据库名称直接作为字符串是错误的，但无论如何对我来说它适用于这个 XML 配置。
