JSP多语言第一种

以jsp页面title举例:

读取多语言肯定要放在properties中，并且通过后台读取properties对应的键返回其值，则jsp页面需要引入类:

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

<%@page import="com.mytest.sys.config.SysTextConfig"%>这里SysTextConfig类处理多语言

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

<title><%=SysTextConfig.getConfigInfo("bsd_text")+SysTextConfig.getConfigInfo("title")%></title>
SysTextConfig类的内容为

public class SysTextConfig { 
     
        private static  Properties properties =null;//读取properties的资源文件  
     
    private  static long lastModified=0;//内存中上次修改的时间 long型  
     
    private  static String filePath=null;//保存properties文件的绝对路径  
     
    private  static File  sysConfigFile=null; 
     
    
   static {//初始化static变量的值  
        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; 
           return false; 
   } 
   
   private static void loadSysConfigFile(){ 
        
       properties = new Properties(); 
       
       FileInputStream fileInputStream; 
       try { 
            fileInputStream = new   FileInputStream(sysConfigFile); 
            properties.load(fileInputStream); 
             
        } catch (Exception e) { 
            // TODO Auto-generated catch block  
            e.printStackTrace(); 
        } 
        
   } 
   public static String getConfigInfo(String key) { 
           //函数入口,首先校验properties文件的最近以次修改时间，如果不为0 则代表其修改过 则要再次加载loadSysConfigFile  
           if(isNotlastModified()) loadSysConfigFile();    
       Object object = properties.get(key);   //读取properties的键  
       String value =""; 
       try { 
           if(StringUtils.isNotEmpty(object)){ 
               value = new String(object.toString().getBytes("ISO8859_1"));//通过键返回其值  
           } 
        } catch (UnsupportedEncodingException e) { 
            e.printStackTrace(); 
        } 
       return value;    
   }    
 
} 

public class SysTextConfig {
 
        private static  Properties properties =null;//读取properties的资源文件
 
 private  static long lastModified=0;//内存中上次修改的时间 long型
   
    private  static String filePath=null;//保存properties文件的绝对路径
   
    private  static File  sysConfigFile=null;
   
  
   static {//初始化static变量的值
     StringBuffer configFilePath = new StringBuffer();
     
     String classPath= SysTextConfig.class.getClassLoader().getResource("").getPath();
     String weninfoPath = classPath.substring(0,classPath.lastIndexOf("classes"));

补充：Web开发 , Jsp ,

上一个：weblogic容器通过JSP页面输出图片出现乱码Tomcat下却正常
下一个：你的Jsp页面有黄×么，有黄色问号么?Multiple annotations found at this line: - Invalid location of tag (form). - No
