如何在PropertyPlaceholderConfigurer中引用JNDI属性?

How can I reference a JNDI property inside a PropertyPlaceholderConfigurer?

具体来说，我正在使用JNDI查找一个java.lang.String，它表示一个到 我的网络应用所需的属性文件

Specifically, I'm using JNDI to look up a java.lang.String that represents a path to a property file needed by my webapp

<jee:jndi-lookup id="mypropsfile1" jndi-name="myPropsFile1" resource-ref="true"/>
<jee:jndi-lookup id="mypropsfile2" jndi-name="myPropsFile2" resource-ref="true"/>

<bean id="propertyConfigurer" 
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="ignoreUnresolvablePlaceholders" value="true"/>
  <property name="locations">
    <array>
        <value>how to use mypropsfile1 here ??</value>
        <value>how to use mypropsfile2 here ??</value>
    </array>
  </property>
</bean>

我的"jee:jndi-lookup"正在运行AFAIK.我的问题似乎是如何引用JNDI资源 标签对内

My "jee:jndi-lookup"s are working AFAIK. My problem seems to be how to reference JNDI resources inside the tag pair

提前谢谢！ 标记

推荐答案

不完全是单个JNDI属性，而是使用通过JNDI获取的Properties引用:

Not exactly for a single JNDI property, this is using a Properties reference instead, obtained through JNDI:

<!-- Lookup Properties reference through JNDI -->
<jee:jndi-lookup id="config-properties" jndi-name="resources/resource-name" resource-ref="true"/>

<bean id="propertyConfigurer" 
      class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" depends-on="config-properties">
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
    <!-- Once the reference is obtained from JNDI, it can be used like any other reference -->
    <property name="properties" ref="config-properties"></property>
</bean>
