我刚开始使用mongodb作为我的新项目的存储库，在我们决定在mongo服务器中设置用户身份验证之前，一切都正常

我将spring.config.xml更改如下，以通过身份验证连接到mongo

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

<bean id="mongoCredentials" class="org.springframework.data.authentication.UserCredentials">
    <property name="username" value="user" />
    <property name="password" value="password" />
</bean>

<bean class="com.mongodb.MongoURI" id="mongoURI">
    <constructor-arg value="mongodb://localhost:27017"  />
</bean>

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

这是堆栈跟踪：
