4.validator-rules.xml这个是struts自带的

Answer 2

4.validator-rules.xml这个是struts自带的,太长了，就不贴出来了
5.ApplicationResources.properties资源文件
# Resources for parameter 'com.gong.struts.ApplicationResources'
# Project StrutsTest1# register.jsp
register.title=Validator使用示例
register.message=请输入注册信息
register.form.name=用户名
register.form.password=密码
register.form.email=邮箱
register.form.age=年龄# validator config
errors.required={0}不能为空
errors.integer={0}必须是整形数字
errors.email={0}不是有效的电子邮件地址
errors.maxlength={0}的长度不能超过{1}个字符
errors.minlength={0}的长度不能少于{1}个字符6.RegisterAction.java
package com.gong.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;

    @Override
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        // TODO Auto-generated method stub

}
7.RegisterForm.java

Answer 3

com.gong.struts.form.RegisterForm
这个form不对，不能是普通的form
应该是validateform 或validateActionfrom
并且不能在其中有validate方法。！

Answer 4

改成
public class RegisterForm extends ValidatorForm 就可以了，继承错了，不应该继承ActionForm类。多谢！
