Struts 2.0校验框架的规范:在相应的Action同级目录下创建名为"Action名-validation.xml"的配置文件

7 1.InputAction-validation.xml验证对应InputAction.java里的属性,表单信息先通过此验证才过Action
8 2.validators:验证框架,fied表明针对域的验证
9 3.fied name="string":name对应的只能是此Action(InputAction.java)里的属性.
10 4.fied-validator:字段效验器.(这里有两个,可设置多个) type="reqiuredString":属性name="string"的验证规则是type="reqiuredString"
11 5.message:错误提示信息.key="empty"表明从资源文件中读取(直接可以I18n)
12 注意:dtd的版本是xwork-validator-1.0.2.dtd,此例子其他版本会出错!
