用struts验证器验证一个List
论坛里有一篇「struts使用list提交多行表单(提供完整示例)」，我能理解并且能实现list提交多行表单的问题。
现在我还有个问题，各位大侠们解答一下，我提交的list数据可以通过form里的validate来验证，可是为了层次清晰更想通过validator验证器来验证，怎么编写自己的验证器方法可以实现。
以下是验证器自定义方法，怎么填充这个方法可以实现验证list呢？
我的list里面有很多字段，我是想用验证器来验证很多字段。
validator-rules.xml配置如下：
<form-validation> <global> <validator name="validateList" classname="org.apache.struts.validator.FieldChecks" method="validateMyList" methodParams="java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionMessages, org.apache.commons.validator.Validator, javax.servlet.http.HttpServletRequest" msg="errors.××××××" /> </global></form-validation>
<form-validation> <global /> <formset> <form name="MyForm"> <!-- 我自定义的form中的list --> <field property="myList" depends="validateList"> <msg name="validateList" key="error.×××××××" /> <arg key="×××××" resource="true" position="0"/> </field> </form> </formset></form-validation>
public static boolean validateMyList( Object bean, ValidatorAction action, Field field, ActionMessages message, Validator validator, HttpServletRequest req) { List target = null; String pattern = null; target = ValidatorUtils.getValueAsList(bean, field.getProperty()); 怎么实现…………… return Boolean.FALSE;}/** * mylist */ private List<CooperationClient> myList;
