如何使用Spring Data（XML配置）連接到CloudBees上的MongoDB？

爲了學習（spring/mongoBD/CLoudBees），我在CloudBees上創建了一個mongoDB實例，並且我試圖使用spring Data連接我的spring應用程序。如何使用Spring Data（XML配置）連接到CloudBees上的MongoDB？

我得到以下錯誤：

我對Spring數據的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:[email protected]:10048/xxxxxxxxxxxxx"/> 
</bean> 

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

當我測試URI的mongodb：// MY_DB_USERNAME：[email protected]： 10048/xxxxxxxxxxxxx使用umongo，它連接正確。

Maven依賴：

spring data mongodb version: 1.3.1.RELEASE 
mongodb driver version: 2.10.1 
spring core version: 3.2.3.RELEASE

什麼我做錯了任何想法？

是你使用管理員用戶的數據庫用戶名？如果是這樣，那麼在對「admin」以外的數據庫進行身份驗證時，您將無法驗證消息。 –

我不認爲這是一個管理員用戶（這是cloudbees上的基本免費計劃，我想這是不可能有一個管理員用戶的計劃），我會檢查是否有可能有一個。謝謝 –

我通過＃{} mongoUri.database所以新豆DEF爲mongoTemplate更換我的DB名「appDB」解決的問題是：

<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>

我不明白爲什麼直接把數據庫名作爲字符串是錯誤的，但無論如何對我來說它適用於這個XML配置。
