spring jndi with propertyPlaceholder

Question

当我使用jndi-place-holder名称为$ {myappdb.jndi}时出现以下错误。 当我使用直接JNDI名称而不是使用占位符名称时，它正常工作。 为什么Spring jndi不从占位符读取JNDI名称？我肯定＆＃34; myappdb.jndi＆＃34;在＆＃34; myapp.cfg＆＃34;中定义文件。

使用：

Weblogic 12c

Spring 3.x

的applicationContext.xml

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
    <property name="ignoreResourceNotFound" value="false"/>
    <property name="order" value="1" />
    <property name="locations">
        <list>
            <value>file:/conf/myapp.cfg</value>
        </list>
    </property>
</bean>

<jee:jndi-lookup id="myapp.db" jndi-name="${myappdb.jndi}"/>

<bean name="myappDbDaoImpl" class="com.myapp.db.myappDbDaoImpl">
    <property name="dataSource" ref="myapp.db" />
</bean>

错误：

    weblogic.application.ModuleException: javax.naming.NameNotFoundException: While trying to lookup '${myappdb.jndi}' didn't find subcontext '${myappdb'. Resolved ''; remaining name '${
myappdb/jndi}'
