struts2 action 标签中的method方法

DefaultActionInvocation

will try to call also 

doDelete

if it couldn't find 

delete

method in action's class.

<action name="delete" class="example.CrudAction" method="delete">

action中的方法名可以为delete，如果CrudAction类中找不到delete会去找doDelete方法

To use a postfix wildcard, just move the asterisk and add an underscore.

<action name="Crud_*" class="example.Crud" method="{1}">使用后缀通配符，要用下划线和星号
