applicationContext的bean初始化

applicationContext.xml配置

<bean id="contextInitBeans" class="com.java1234.init.impl.ContextInitBeans" init-method="init" lazy-init="false">
       <property name="contextInitBeans" >
           <list>
               
               <bean id="globalPathInit" class="com.java1234.init.impl.GlobalPathInit" lazy-init="false" >
                   <property name="urlMap">
                       <map>
                           <entry key="serverPath"><value>${tongda.global.serverPath}</value></entry>
                           <entry key="searchPath"><value>${tongda.global.searchPath}</value></entry>
                           <entry key="resourcePath"><value>${tongda.global.resourcePath}</value></entry>
                       </map>
                   </property>
               </bean>
           </list>
           </property>
   </bean>
