再问struts

请问struts中的applicationResources.properties的工作原理?

我做了两个资源文件，一个是中文，一个是英文，中文命名为applicationResources.properties，英文命名为test.properties。请问浏览器如何去判断这两个文件的？

struts-config.xml的配置如下：
<message-resources parameter="com.migo.struts.ApplicationResources" />
=============================================================================================================
why????

设置浏览器语言为英文后，它是怎么去找相应资源文件的？

[nanjg]

可以查看相关实现源码

例如可以改相关源码后实现 此文件中直接写中文

applicationResources_en.properties

楼上的可否说明白一些， 我还是不太明白。系统中存在两个不同的资源文件，浏览器怎么知道哪一个是英文，哪一个是中文，在struts-config.xml中也没有配置 ，很奇怪!!!

服务器根据locale读取资源，资源名是applicationResources，如locale代表中国则寻找对应的applicationResources_zh.properties
楼主看下api里的ResourceBundle

先看个文件，Locale.java，这个类定义了一些国际化需要的Locale。
/** Useful constant for language.
*/
static public final Locale ENGLISH = new Locale("en","","");

/** Useful constant for language.
*/
static public final Locale FRENCH = new Locale("fr","","");

/** Useful constant for language.
*/
static public final Locale GERMAN = new Locale("de","","");

/** Useful constant for language.
*/
static public final Locale ITALIAN = new Locale("it","","");

/** Useful constant for language.
*/
static public final Locale JAPANESE = new Locale("ja","","");

/** Useful constant for language.
*/
static public final Locale KOREAN = new Locale("ko","","");

/** Useful constant for language.
*/
static public final Locale CHINESE = new Locale("zh","","");

/** Useful constant for language.
*/
static public final Locale SIMPLIFIED_CHINESE = new Locale("zh","CN","");

/** Useful constant for language.
*/
static public final Locale TRADITIONAL_CHINESE = new Locale("zh","TW","");

/** Useful constant for country.
*/
static public final Locale FRANCE = new Locale("fr","FR","");

/** Useful constant for country.
*/
static public final Locale GERMANY = new Locale("de","DE","");

/** Useful constant for country.
*/
static public final Locale ITALY = new Locale("it","IT","");

/** Useful constant for country.
*/
static public final Locale JAPAN = new Locale("ja","JP","");

/** Useful constant for country.
*/
static public final Locale KOREA = new Locale("ko","KR","");

/** Useful constant for country.
*/
static public final Locale CHINA = new Locale("zh","CN","");

/** Useful constant for country.
*/
static public final Locale PRC = new Locale("zh","CN","");

/** Useful constant for country.
*/
static public final Locale TAIWAN = new Locale("zh","TW","");

/** Useful constant for country.
*/
static public final Locale UK = new Locale("en","GB","");

/** Useful constant for country.
*/
static public final Locale US = new Locale("en","US","");

/** Useful constant for country.
*/
static public final Locale CANADA = new Locale("en","CA","");

/** Useful constant for country.
*/
static public final Locale CANADA_FRENCH = new Locale("fr","CA","");

Struts的国际化是根据用户的浏览器的语言设置来读取不同语言的信息，这个属性就是Locale，这是个全局的，保存在Struts的Session里。也就是说，如果可以动态的更改这个Locale就可以实现一个浏览器动态的读取不同的资源文件了。
在Action中，我这样做的，
if(language.equals("01")){
request.getSession().setAttribute(Globals.LOCALE_KEY, Locale.SIMPLIFIED_CHINESE);
}else if(language.equals("02")){
request.getSession().setAttribute(Globals.LOCALE_KEY, Locale.ENGLISH);
}
...............
这个地方，01代表中文语言，02是英语....
当用户请求的是中文时，利用
request.getSession().setAttribute(Globals.LOCALE_KEY, Locale.SIMPLIFIED_CHINESE)将Locale设置为简体中文的，这时候jsp在读取properties文件时，会调用 XXX_zh_CN.properties文件。不同的语言就设置不同的Locale。 只要配好不同语言的文件，就OK了。

感谢楼上的兄弟，说得很详细
