Spring-data-mongodb db-factory id不起作用

我有mongo-config.xml的工作副本，它使用db-factory的默认id：

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:mongo="http://www.springframework.org/schema/data/mongo"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd
        http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.4.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<mongo:mongo id="replicaSetMongo" replica-set="localhost:10901,localhost:10902">
<mongo:options connections-per-host="8"
ssl="false" />
</mongo:mongo>

<mongo:db-factory
mongo-ref="replicaSetMongo"
dbname="logs"
username="logs_owner"
password="logs_owner" />

<mongo:mapping-converter>
<mongo:custom-converters>
<mongo:converter>
<beanclass="com.utils.mongodb.dao.impl.SspLogsWriteConverter"/>
</mongo:converter>
</mongo:custom-converters>
</mongo:mapping-converter>

<beanid="xmlLogTemplate"class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
<constructor-arg name="mongoConverter" ref="mappingConverter"/>
<propertyname="writeConcern">
<util:constant static-field="com.mongodb.WriteConcern.UNACKNOWLEDGED"/>
</property>
</bean>

</beans>

但是我们要求在同一个mongodb副本集上连接到2个不同的数据库。因此，我想定义2个不同的mongo：db-factory bean。所以我做了以下改动： （只有更改过的bean如下所示）

<mongo:db-factory id="xmlDbFactory" 
    mongo-ref="replicaSetMongo"
    dbname="logs"
    username="logs_owner"
    password="logs_owner" />

<beanid="xmlLogTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="xmlDbFactory"/>
    <constructor-arg name="mongoConverter" ref="mappingConverter"/>
    <property name="writeConcern">
    <util:constant static-field="com.mongodb.WriteConcern.UNACKNOWLEDGED"/>
    </property>
    </bean>

一旦我部署了这个更改，我的JBoss就会在启动时开始抛出错误，如下所示。 这是春天的错误，还是我做错了什么？

问题不在于db-factory，而是具有可选参数“db-factory-ref”的映射转换器。此参数在内部预设为“mongoDbFactory”以匹配db-factory的默认“id”。

所以db-factory的“id”有效，但是必须相应地设置mongo-conver的“db-factory-ref”：

<mongo:db-factory id="xmlDbFactory" ... />
<mongo:mapping-converter db-factory-ref="xmlDbFactory">
