新人，求帮助（struts 框架验证）
本来想试试struts的框架验证，结果它不执行form 的validate()
代码如下：
Form
package com.yourcompany.struts.form;
import org.apache.struts.validator.ValidatorActionForm;
public class loginForm extends ValidatorActionForm{
private String userName;
private String passWord;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
}
Action
package com.yourcompany.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class LoginAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
return null;
}
}
