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:

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

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.
