struts2 国际化与防止刷新重复提交表单

struts2 国际化与防止刷新重复提交表单
本实例主要是功能是实现国际化,防止刷新得利提交表单,利用struts2的验证机制验证字符输入的合法性,邮箱输入的正确性:
本实例用两个页面(create.jsp,createResult.jsp),一个Action(CreateAction),一个验证文件(CreateAction-validation.xml),两个国际化文件(message_en_US.properties,message_zh_CN.properties),还有一个struts.xml(必有的).创建用户成功之后,显示刚才创建的信息,不成功则显示错误提示,错误提示使用
了国际化来显示,输入合法性就用了用struts2的验证机制验证.
如下结构图,好好对照:

1.CreateAction.java
// ******************************************************************
package cn.struts2;

import java.util.Date;

import com.opensymphony.xwork2.ActionSupport;

public class CreateAction extends ActionSupport
{
private String name ;
private String password;
private String repassword;
private Date birthday;
private Date registedDay;
private int age;
private String email;

/**
* @return the name
*/
public String getName()
{
return name;
}
/**
* @param name the name to set
*/
public void setName(String name)
{
this.name = name;
}
/**
* @return the password
*/
public String getPassword()
{
return password;
}
/**
* @param password the password to set
*/
public void setPassword(String password)
{
this.password = password;
}
/**
* @return the repassword
*/
public String getRepassword()
{
return repassword;
}
/**
* @param repassword the repassword to set
*/
public void setRepassword(String repassword)
{
this.repassword = repassword;
}
/**
* @return the birthday
*/
public Date getBirthday()
{
return birthday;
}
/**

*/

{
this.birthday = birthday;
}
/**

*/
public Date getRegistedDay()
{
return registedDay;
}
/**

*/
public void setRegistedDay(Date registedDay)
{
this.registedDay = registedDay;
}
/**

/**

}

public String getEmail()
{

}
public void setEmail(String email)
{
this.email = email;
}
//****************************************

public String execute()throws Exception
{
return SUCCESS;
}

}

//******************************************************************



2.置全局国际化文件(两个):
// message_en_US.properties ********************************************
create = Create Users Information
username.invalid = User Name Not Null!
password.invalid.null = Password Not Null!
password.invalid.too.short.or.long = Password should be between 6 and 10
submit = submit
//***********************************************************************
中文国际化
// message_zh_CN.properties ********************************************
create = /u521b/u5efa/u7528/u6237/u4fe1/u606f
username.invalid = /u7528/u6237/u540d/u4e0d/u80fd/u4e3a/u7a7a
password.invalid.null = /u5bc6/u7801/u4e0d/u80fd/u4e3a/u7a7a
password.invalid.too.short.or.long = /u5bc6/u7801/u957f/u5ea6/u5fc5/u987b/u57286/u523010/u4e4b/u95f4
submit =/u63d0/u4ea4

//***********************************************************************
注意:如(create = /u521b/u5efa/u7528/u6237/u4fe1/u606f)等号右边的一串乱码是中文字符对就的ASCII码值,如果你需要转换,可以打开你的CMD(开始-->运行-->输入CMD即可),输入命令native2ascii,回车,将你的中文字符粘上,再回车就可以看到一串乱码了.再将其COPY到相应的位置即可.
文件的名字不能乱取,XXX_en_US.properties,XXX_zh_CN.properties,XXX后面的名字是固定的,而前面的XXX是根据你的struts.xml文件中的 <constant name="struts.custom.i18n.resources" value="XXX"></constant>中的XXX而取的.本例的XXX就是message.

3.struts.xml
// ************************************************************************
<?xml version="1.0" encoding="UTF-8"?>

<!-- avoid refresh again -->

<interceptor-ref name="token"></interceptor-ref>
<interceptor-ref name="defaultStack"></interceptor-ref>

5.JSP文件
(1)
// createResult.jsp ************************************************************************

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

6.验证文件(注意名字要与你的Action名字一样,后面再跟固定的(-validation.xml)如(CreateAction-validation.xml)

CreateAction-validation.xml:
// ****************************************************************************
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">

<!-- 格式的写法可以参照XWork Validator 1.0.2.dtd -->
<!-- 参数设置参照xwork-2.0.5.jar 下的com.opensymphony.xwork2.validator.validators/default.xml -->
<validators>


<!--验证谁, 用谁来验证 -->
<field name="name">
<field-validator type="requiredstring">
<!--requiredstring对应的类的方法里的参数名trim 如public void setTrim(boolean trim)里的trim -->
<param name="trim">true</param>
<!-- message key的key内容是I18N里(即baseName_zh_CN.properties和baseName_en_US.properties中)定义的字段名即等号在边的名字如(username.invalid = 名字不能为空)-->
<message key="username.invalid"></message>
</field-validator>
</field>

<field name="password">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message key="password.invalid.null"></message>
</field-validator>
</field>
<field name="password">
<field-validator type="stringlength">
<param name="minLength">6</param>
<param name="maxLength">16</param>
<message key="password.invalid.too.short.or.long"></message>
</field-validator>
</field>

<!-- 以下未做国际化 -->
<field name="age">
<field-validator type="int">
<param name="min">1</param>
<param name="max">150</param>
<message>age should be between ${min} and ${max}</message>
</field-validator>
</field>

<field name="birthday">
<field-validator type="required">
<message>birthday not null!</message>
</field-validator>

<field-validator type="date">
<param name="min">2000-01-01</param>
<param name="max">2008-01-01</param>
<message>birthday should be between ${min} and ${max}</message>
</field-validator>
</field>

<field name="email">
<field-validator type="email">
<message>email format error!</message>
</field-validator>
</field>

</validators>
