Background string internationalization in spring

1. Create three properties files in the project's Resource folder (source folders): Messages.properties (default), Messages_zh_cn.properties (Chinese), Messages_en_ Us.properties (English).

The string resource in the properties file fills in the information in the form of a key-value pair, as follows:

Helloworld= Greeting: @0 greeting time: @1;

2. Tool class universalmsgto get internationalized strings:

　　

 Packagecom.luxl.action;ImportJava.util.Locale;ImportJava.util.ResourceBundle;/*** @description used to get internationalized strings *@authorLUXL **/ Public classuniversalmsg {Private StaticResourceBundle rb_ch = Resourcebundle.getbundle ("Messages", Locale.china); Private StaticResourceBundle rb_en = Resourcebundle.getbundle ("Messages", locale.us); /*** @description Get the internationalized string for key *@paramLocale Language: Chinese (Locale.china), English (locale.us) *@paramkey to get the string of key *@return     * @throwsException*/     Public StaticString getString (locale locale, string key)throwsexception{if(key!=NULL&& (!Key.trim (). IsEmpty ())) {            if(Locale.equals (Locale.china)) {returnrb_ch.getstring (key); }Else{                returnrb_en.getstring (key); }        }Else{            return""; }    }        /*** @description Get the Chinese string of key *@paramKey *@return     * @throwsException*/     Public StaticString getString (String key)throwsexception{if(key!=NULL&& (!Key.trim (). IsEmpty ())) {            returnrb_ch.getstring (key); }Else{            return""; }    }}

3. Application Examples:

Try {    String us_msg;     = Universalmsg.getstring (locale.us, "HelloWorld");     = Us_msg.replaceall ("@0", Helloworld.getmsg ());     = Us_msg.replaceall ("@1", Calendar.getinstance (). GetTime (). toString ());     Catch (Exception e) {    //  TODO auto-generated catch block    System.out.println (" Error ");    E.printstacktrace ();}  

Note: If you do not find a string that corresponds to key, an exception is thrown.
