Spring PropertyPlaceholderConfigurer 和 MongoDB 副本集

Question

在我的 spring 上下文中，我使用 PropertyPlaceholderConfigurer 从 env.properties 加载属性:

<bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
       <property name="locations">
            <list>
                <value>classpath:env.properties</value>
            </list>
        </property>
</bean>

在我的 env.properties 中我有以下内容:

db.mongo.replicationset=server1:1111, server2:2222, server3:3333

最后，在 spring 上下文中:

<mongo:mongo id="mongo" replica-set="${db.mongo.replicationset}">
    <mongo:options slave-ok="true"/>
</mongo:mongo>

我看到 java.lang.ArrayIndexOutOfBoundsException:

ERROR: org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [root-context.xml]; nested exception is java.lang.ArrayIndexOutOfBoundsException: 1

一切都适用于硬编码复制集，如下所示:

<mongo:mongo id="mongo" replica-set="server1:1111, server2:2222, server3:3333">
    <mongo:options slave-ok="true"/>
</mongo:mongo>

我的猜测是冒号或逗号可能是 PropertyPlaceholderConfigurer 的特殊字符，因此不能使用。

我怎样才能让这个配置与 PropertyPlaceholderConfigurer 和属性文件一起工作。

编辑此问题已针对 spring-data-mongodb:1.0.0.RELEASE 和 spring-data-mongodb:1.1.0.M1 修复

这实际上是最新的 Spring-data-mongo M5 里程碑中的一个错误。
