     处理请求页面中文字符集  
     request.setCharacterEncoding("gbk");  
     response.setContentType("text/html; charset=gbk");  
     //得到表单中附件  
     File file = this.doAttachment(request);  
     //包含附件功能的邮件定义  
     MultiPartEmail email = new MultiPartEmail();  
     //设置邮件发送的服务器  
     email.setHostName("smtp.163.com");  
     //邮件发送验证用户名，密码  
     email.setAuthentication("用户名", "密码");  
     //设置邮件接收字符集

         email.addTo(parameters.get("to"));  
         email.setFrom(parameters.get("from"));

         email.setMsg(parameters.get("content"));  
         if (file != null) {  
             //邮件添加附件，设置邮件附件的路径、类型、名称  
             EmailAttachment attachment = new EmailAttachment();  
             attachment.setPath(file.getPath());  
             attachment.setDisposition(EmailAttachment.ATTACHMENT);
