java - Struts ActionForm 替换为 ValidatorForm

Question

将下面的ActionForm替换为ValidatorForm是否会导致现有逻辑发生任何变化？

public class EditForm extends ActionForm {

existing logic(setters(), getters(), reset(), validate() )

}

与

public class EditForm extends **ValidatorForm**{

existing logic(setters(), getters(), reset(), validate()  --> **will it be affected?**

}

Answer 1

真正的区别是:

This class extends ActionForm and provides basic field validation based on an XML file. The key passed into the validator is the action element's name attribute from the struts-config.xml which should match the form element's name attribute in the validation.xml.

但是，可能会改变的逻辑是出现验证错误时要执行的操作。
