import java.io.BufferedReader;  
    import java.io.File;  
    import java.io.FileInputStream;  
    import java.io.FileNotFoundException;  
    import java.io.IOException;  
    import java.io.InputStreamReader;  
      
    public class ReadHTML {  
      
        /** 
         * @param args 
         */  
        //public static void main(String[] args) {  
            // TODO Auto-generated method stub  
        public static String reMailString(){  
            //String info="";  
            StringBuffer buff=new StringBuffer();  
            InputStreamReader in=null;  
            BufferedReader br=null;  
            String realPath = Thread.currentThread().getContextClassLoader().getResource("/").getPath();
            String path=realPath.replace("classes/", "template/front/emailcode.html");
            File file=new File(path);  
            try {  
                in=new InputStreamReader(new FileInputStream(file));  
                br=new BufferedReader(in);  
                String line=null;  
                while((line=br.readLine()) != null){  
                   // System.out.println(line);  
                    buff.append(line).append("\n");  
                }  
                  
                  
            } catch (FileNotFoundException e) {  
                e.printStackTrace();  
            } catch (IOException e) {  
                e.printStackTrace();  
            }finally{  
                if(in!=null){  
                    try {  
                        in.close();  
                    } catch (IOException e) {  
                        e.printStackTrace();  
                    }  
                }  
                if(br!=null){  
                    try {  
                        br.close();  
                    } catch (IOException e) {  
                        e.printStackTrace();  
                    }  
                }  
            }  
              
            return buff.toString();  
        }  
        public static void main(String[] args) {
        	ReadHTML.reMailString();
    	}
      
    }

用上面的类进行读取发送到邮箱的HTML代码，再通过java的mail进行邮箱的发送。
