JSP多語言第一種

以jsp頁面title舉例:

讀取多語言肯定要放在properties中，並且通過後台讀取properties對應的鍵返回其值，則jsp頁面需要引入類:

<%@page import="com.mytest.sys.config.SysTextConfig"%> 

<%@page import="com.mytest.sys.config.SysTextConfig"%>這裡SysTextConfig類處理多語言

<title><%=SysTextConfig.getConfigInfo("bsd_text")+SysTextConfig.getConfigInfo("title")%></title> 

<title><%=SysTextConfig.getConfigInfo("bsd_text")+SysTextConfig.getConfigInfo("title")%></title>
SysTextConfig類的內容為

public class SysTextConfig { 
     
        private static  Properties properties =null;//讀取properties的資源文件  
     
    private  static long lastModified=0;//內存中上次修改的時間 long型  
     
    private  static String filePath=null;//保存properties文件的絕對路徑  
     
    private  static File  sysConfigFile=null; 
     
    
   static {//初始化static變量的值  
        StringBuffer configFilePath = new StringBuffer(); 
         
        String classPath= SysTextConfig.class.getClassLoader().getResource("").getPath(); 
        String weninfoPath = classPath.substring(0,classPath.lastIndexOf("classes")); 
         
        configFilePath.append(weninfoPath).append("config"); 
         
        configFilePath.append(File.separator).append("sysText.properties"); 
         
        filePath=configFilePath.toString();  
    } 
    
   private static boolean isNotlastModified(){ 
       sysConfigFile= new File(filePath); 
        
       if( sysConfigFile.lastModified()!=lastModified) 
           return true;

   } 
   public static String getConfigInfo(String key) { 
           //函數入口,首先校驗properties文件的最近以次修改時間，如果不為0 則代表其修改過 則要再次加載loadSysConfigFile  
           if(isNotlastModified()) loadSysConfigFile();    
       Object object = properties.get(key);   //讀取properties的鍵  
       String value ="";

               value = new String(object.toString().getBytes("ISO8859_1"));//通過鍵返回其值  
           } 
        } catch (UnsupportedEncodingException e) { 
            e.printStackTrace(); 
        } 
       return value;    
   }
