struts2校验の实现
1.JSP
<%@ page contentType="text/html; charset=utf-8" language="java" errorPage="" pageEncoding="utf-8" %> <%@taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>请输入您的注册信息</title> </head> <body> <h2>请输入您的注册信息</h2> <s:fielderror/> <s:form action="regist"> <s:textfield name="name" label="用户名"/> <s:textfield name="pass" label="密码"/> <s:textfield name="age" label="年龄"/> <s:textfield name="birth" label="生日"/> <s:submit value="注册"/> </s:form> </body> </html>
2.Action
package com.mi.action;
import com.opensymphony.xwork2.ActionSupport;
import java.util.Date;
public class RegistAction extends ActionSupport
{
/**
*
*/
private static final long serialVersionUID = 1L;
// ｶｨﾒ�4ｸﾉﾔｱｱ菽ｿｷ籏ｰﾇ�ﾇﾎﾊ�
private String name;
private String pass;
private int age;
private Date birth;
// nameｵﾄsetterｺﾍgetterｷｽｷｨ
public void setName(String name)
{
this.name = name;
}
public String getName()

}
// passｵﾄsetterｺﾍgetterｷｽｷｨ
public void setPass(String pass)
{

}
public String getPass()

}
3.struts.xml
