// xmlns:aop/tx/jee/context 对应的namespace，自定义namespace的作用是相同名字的标签不会冲突，因为有对应的前缀，如<aop:xxx />等

<!-- 如果是默认的namespace（beans）的标签，那直接写就可以了，如： -->
<bean id="xxx" class="xxx"/>
<!-- 如果是非默认的namespace，如aop/tx/jee/context，那就要这么写对应的标签： -->
<aop:xxx a="1" b="2" />
<tx:xxx a="1" b="2" />
<jee:xxx a="1" b="2" />
<context:xxx a="1" b="2" />
