在velocity使用toolbox.xml

发布时间：2020-12-16 00:27:47 所属栏目：百科来源：网络整理

导读：首先必须在web.xml中添加： org.apache.velocity.toolbox /WEB-INF/toolbox.xml 才可以使用toolbox.xml中定义的变量。举例说明用法比如我要使用日期，可以如下定义： date application org.apache.velocity.tools.generic.DateTool 这里DateTool是velocity

首先必须在web.xml中添加： org.apache.velocity.toolbox /WEB-INF/toolbox.xml
才可以使用toolbox.xml中定义的变量。

举例说明用法比如我要使用日期，可以如下定义： date application org.apache.velocity.tools.generic.DateTool 这里DateTool是velocity为我们预定义的工具类，还有很多其他工具类（比如：MathTool，ListTool，SortTool...） date是这个类的实例，这样我们就可以在.vm中使用$date来引用DateTool中的方法了，如 $date.get('yyyy-M-d H:m:s')

如果我们要使用自己的类，只需要把org.apache.velocity.tools.generic.DateTool这部分替换成自己定义的类，然后再初始化该类的实例，比如 class 在.vm中这样用$class.getXXX()

toolbox.xml典型配置： Java代码收藏代码
