struts2 國際化,防止刷新重複提交表單與郵箱格式驗證

            struts2 國際化與防止刷新重複提交表單
    本實例主要是功能是實現國際化,防止刷新得利提交表單,利用struts2的驗證機制驗證字符輸入的合法性,郵箱輸入的正確性:
本實例用兩個頁面(create.jsp,createResult.jsp),一個Action(CreateAction),一個驗證文件(CreateAction-validation.xml),兩個國際化文件(message_en_US.properties,message_zh_CN.properties),還有一個struts.xml(必有的).創建用戶成功之後,顯示剛纔創建的信息,不成功則顯示錯誤提示,錯誤提示使用
了國際化來顯示,輸入合法性就用了用struts2的驗證機制驗證.
如下結構圖,好好對照:

2.置全局國際化文件(兩個):
// 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
//***********************************************************************
中文國際化
// 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)等號右邊的一串亂碼是中文字符對就的ASCII碼值,如果你需要轉換,可以打開你的CMD(開始-->運行-->輸入CMD即可),輸入命令native2ascii,回車,將你的中文字符粘上,再回車就可以看到一串亂碼了.再將其COPY到相應的位置即可.
文件的名字不能亂取,XXX_en_US.properties,XXX_zh_CN.properties,XXX後面的名字是固定的,而前面的XXX是根據你的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.
