java JNDI路劲配置

在tomcat中 conf/context.xml 文件中增加

<Environment name="GROUP/CHINASOFTI/VTM/CONTENT_REPOSITORY" value="D:\workspace01\vtm\group-vtm-sln-content-repository\src\main\resources" type="java.lang.String" override="false"/>

在xml文件中使用方式：

<bean id="exampleProperty" class="com.chinasofti.vtmsln.config.ExtendedMessageSource">
<property name="basename" value="file:#{contentRepositoryRootPath}/repository/gwis/gwis"></property>
</bean>

<jee:jndi-lookup id="contentRepositoryRootPath" jndi-name="GROUP/CHINASOFTI/VTM/CONTENT_REPOSITORY" 
expected-type="java.lang.String" resource-ref="true"></jee:jndi-lookup>
