Question

在我的spring环境中，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，在春天的背景下：

<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

所有内容都适用于硬代码复制 - 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，因此无法使用。

如何使用PropertyPlaceholderConfigurer和属性文件进行此配置。

修改 spring-data-mongodb修复此问题：1.0.0.RELEASE和spring-data-mongodb：1.1.0.M1

这实际上是最新的Spring-data-mongo M5里程碑中的一个错误 http://forum.springsource.org/showthread.php?114672-Replica-set-configuration-problem

以下作品：

<mongo:mongo
replica-set="${mongo.replicaset.1}:${mongo.replicaset.1.port},${mongo.replicaset.2}:${mongo.replicaset.2.port},${mongo.replicaset.3}:${mongo.replicaset.3.port}">

Spring PropertyPlaceholderConfigurer和MongoDB副本集
