struts2.xml的自带校验的使用

1、前台含有form表单的页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>struts2测试页面</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

</head>

<body>
<s:form action="login.action" method="post" namespace="/login">
<s:textfield name="username" key="user"></s:textfield>
<s:textfield name="password" key="pass"></s:textfield>
<s:submit key="submit" value="submit"></s:submit>
</s:form>
</body>
</html>

2、后台java以及同目录的xml，名字分别为 Test.java,Test-validation.xml

Test.java

package demo.action;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;

import org.apache.commons.codec.digest.DigestUtils;

import com.opensymphony.xwork2.ActionSupport;

public class Test extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;

String username;
String password;

//测试页面-跳转到输入数据的form表单
public String test(){

return "tologinform";
}

//-登录页面中form表单提交的路径
public String login(){
System.out.println("form表单提交路径正确");

return "ok";
}

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;
}

}

Test-validation.xml

里面的表头的dtd来自，xwork-core-2.2.3.jar的xwork-calidator-1.0.3.dtd,类似即可，你在Test-validation.xml敲代码“ <”之后按 alt+/有代码提示就对了

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//Apache Struts//XWork Validator 1.0.2//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd">
<validators>
<field name="username">
<field-validator type="requiredstring">
<message>error</message>
</field-validator>
</field>
<field name="password">
<field-validator type="requiredstring">
<message>error</message>
</field-validator>
</field>
</validators>
