How to connect to MongoDB on CloudBees using Spring Data (XML config)?

Question

To learn (spring/mongoBD/CLoudBees), I have created a mongoDB instance on CloudBees, and I am trying to connect my spring app using spring Data.

I get the following error:

Caused by: org.springframework.data.mongodb.CannotGetMongoDbConnectionException: 
Failed to authenticate to database [appDB], username = [MY_DB_USERNAME], password = [b**********1]

My XML config for Spring Data:

<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>

When I test my URI mongodb://MY_DB_USERNAME:MY_DB_PASS@paulo.mongohq.com:10048/xxxxxxxxxxxxx using umongo, it connects correctly.

Maven dependencies:

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

Any idea about what I am doing wrong ?

Answer 1

I solved the problem by replacing my DB name "appDB" by #{mongoUri.database} so the new Bean def for mongoTemplate is:

<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>

I don't understand why putting the DB name directly as String is wrong, but anyway for me it works with this XML config.
