JSF Spring Bean richfaces HTML

国际化的问题有多种实现方法，由于项目需要，最近研究了下，不敢独享。

以下是步骤
1.建立资源bundle文件（以下文件必须建立在src目录下，我放在com.talgroup.international.quotation包下面）

首先建立 UIResources_en_US.txt

Index=Index:
UserCode=User Code:
UserRole=User Role:
Password=Password:
UserGroup=User Group:
Login=Login
Test=?,<>.;:'"{}()#$%&*@ !^/

UIResources_zh_CN.txt

Index=序列号:
UserCode=用户名:
UserRole=用户角色:
Password=密码:
UserGroup=用户组:
Login=登陆
Test=?,<>.;:'"{}()无悔一腔血有意济苍生#$%&*@ !^/

然后建立转码程序

native2ascii(en-us).bat

native2ascii -encoding TIS-620 UIResources_en_US.txt > UIResources_en_US.properties

native2ascii(zh-cn).bat

native2ascii -encoding gb2312 UIResources_zh_CN.txt > UIResources_zh_CN.properties

最后运行两个批处理程序，产生两个properties文件

2.spring 的application-context.xml文件中配置资源bundle文件

<bean id="messageSource"
  class="org.springframework.context.support.ResourceBundleMessageSource">
  <property name="basename">
   <value>com.talgroup.international.quotation.UIResources</value>
  </property>
</bean>

3.建立后台bean

package com.talgroup.web.quotation.ui;
import java.util.Locale;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import org.springframework.web.util.JavaScriptUtils;
import org.springframework.web.util.HtmlUtils;
public class InternationalBean {

private static String lan="en_US";
    private static String jsStr=null;
    private static String htmlStr=null;
//    ApplicationContext context= new FileSystemXmlApplicationContext("/WEB-INF/resource-config.xml");
    private static org.springframework.context.support.ResourceBundleMessageSource context = (org.springframework.context.support.ResourceBundleMessageSource)com.talgroup.app.frmwork.Context.getBean("messageSource");


public String getLan() {
  return lan;
}

public void setLan(String lan) {
  this.lan = lan;
}

public String zh_CN_Action()
{
  this.setLan("zh_CN");
  return null;
}

public String zh_HK_Action()
{
  this.setLan("zh_HK");
  return null;
}

public String en_US_Action()
{
  this.setLan("en_US");
  return null;
}

public static Locale mapStrToLocale(String lan)
{
  if(lan.equals("zh_CN")) return Locale.CHINA;
  if(lan.equals("en_US")) return Locale.US;

  return Locale.US;
}

public static String JavaScriptEscape(String arg)
{
  String str = context.getMessage(arg, null, mapStrToLocale(lan));
  jsStr = JavaScriptUtils.javaScriptEscape(str);
  return jsStr;
}

public static String HtmlEscape(String arg)
{
  String str = context.getMessage(arg, null, mapStrToLocale(lan));
  //htmlStr = HtmlUtils.htmlEscape(str);
  return str;
}

}

4.jsf的face-config.xml中注册管理bean，session级别

<managed-bean>
  <managed-bean-name>internationalBean</managed-bean-name>
  <managed-bean-class>
   com.talgroup.web.quotation.ui.InternationalBean
  </managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

5.页面表现层

ps：

xmlns:js="http://www.talgroup.com/quotation/tags" 和xmlns:html="http://www.talgroup.com/quotation/tags">

是我自定义的两个标签，它主要是用来接受页面传过来的键值（例如：Index，UserCode。。。）将它传到后台bean（InternationalBean）中，然后根据这个键值去资源文件中查找相应的message值，最后返回到页面显示，当然这里面涉及到特殊字符转义的问题，这在bean里面都做了处理了。

至于标签如何定义，如何传参数，由于篇幅原因，我将在下一篇文章中做详细的介绍。
