完整的mongoDb配置信息如下，credentials包括三部分，用户名，密码，数据库名称，如果少写了@${mongo.dbname}就会报以上的错误信息

<mongo:mongo-client id="mongo-client" host="${mongo.host}" port="${mongo.port}"        

  credentials="${mongo.username}:${mongo.password}@${mongo.dbname}">
  
  <mongo:client-options write-concern="SAFE"/> </mongo:mongo-client> 
  
  <mongo:db-factory id="mongoDbFactory" dbname="${mongo.dbname}" mongo-ref="mongo-client" /> 
  
  <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"> 
  
  <constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/> </bean>
