为以后用到的时候有个参照，仅此而已。

框架：struts1+Spring

情形（1）从后台取出数据放入select中并默认选中之前选的

<select name="fullname" style="width: 140px;"class="selectWidth" id="fullname" onChange="changeName()">
	 <option value="0"></option>
<logic:iterate id="list" name="names">
	<option value="<bean:write name="list" property="employeeid"/>" <c:if test="${app.employeeid==list.employeeid }">selected </c:if> >
	    <bean:write name="list" property="employeeName" />
	</option>
</logic:iterate>
</select>

说明一点，后台是request.setAttribute("names",names)，所以这里name=“names”即是要遍历的后台request里的List，便利出来的对象定义为list (id="list")

<bean:write name="list" property="employeeid" />即取出对象的employeeid属性

这里需要注意，struts1也是支持ognl的，网上有好多人说不可以，但这却真真实实的“${app.fullname==list.employeeid}”可以，您也可以在百度里看jstl中也有跟el的混合使用。

情形（2）点击某个链接显示或隐藏

<div onClick='showhidediv("msg")' id="unfold" >+show or hidden</div>

。。。。。。

js代码：

情形3 ajax实现选择某人后出现此人信息

所以这里进行了分割传回的数据

情形4 用Spring发送邮件

先配置邮件的邮箱

mail.smtp.auth=true  
mail.smtp.timeout=25000  
mail.smtp.starttls.enable=true  
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory  
mail.smtp.socketFactory.fallback=false  

email.smtpHost=smtp.gmail.com
email.port=465
email.from=xx@gmail.com
email.username=xx@gmail.com
email.password=xx

下面定义发送邮件的类

public class NewEmailSender implements Runnable {
	
	//get info from resource file
	static String host=ResourceBundle.getBundle("email").getString("email.smtpHost");
	static String port=ResourceBundle.getBundle("email").getString("email.port");
	static String mailFrom=ResourceBundle.getBundle("email").getString("email.from");
	final static String username =ResourceBundle.getBundle("email").getString("email.username");
	final static String password = ResourceBundle.getBundle("email").getString("email.password");
	
	
	private List<String> mailTo;
	private List<String> cc;
	private String subject;
	private String msgContent;
	
	
	public NewEmailSender(){
		
	}
	public NewEmailSender(List<String> mailTo,List<String> cc,String subject,String msgContent){
		this.mailTo=mailTo;
		this.cc=cc;
		this.subject=subject;
		this.msgContent=msgContent;
	}
	public static Session getMailSession()
	{
		String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
		Properties props = System.getProperties();
		props.setProperty("mail.smtp.host", host);
		props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
		props.setProperty("mail.smtp.socketFactory.fallback", "false");
		props.setProperty("mail.smtp.port", port);
		props.setProperty("mail.smtp.socketFactory.port", port);
		props.put("mail.smtp.auth", "true");
		Session sendMailSession= Session.getInstance(props, new Authenticator(){
			protected PasswordAuthentication getPasswordAuthentication() {
			    return new PasswordAuthentication(username, password);
			}
		});
		
		return sendMailSession;
	}
	
	
	public void sentEmail(List<String> mailTo,List<String> cc,String subject,String msgContent)
	{
		try{
			Session sendMailSession=getMailSession();
			Message msg = new MimeMessage(sendMailSession);
			
			msg.setFrom(new InternetAddress(username));
			// set the mailTo recipients
			InternetAddress[] address = new InternetAddress[mailTo.size()];
			for (int i = 0; i<mailTo.size(); ++i)
			{
				address[i] = new InternetAddress(mailTo.get(i));
			}
			msg.setRecipients(Message.RecipientType.TO, address); 
			// set the cc recipients
			if (cc != null)
			{
				System.out.println("bcc："+cc.size());
				address = new InternetAddress[cc.size()];
				for (int i = 0; i<cc.size(); ++i)
				{
					address[i] = new InternetAddress(cc.get(i));
				}
				msg.setRecipients(Message.RecipientType.CC, address);
			} 

			/****/
			msg.setSubject(subject);
			//msg.setText(msgContent);
			msg.setContent(msgContent, "text/html");
			msg.setSentDate(new Date());
			Transport.send(msg);
			
			System.out.println("Message sent.");
		} 
		catch(MessagingException m) 
		{ 
			System.out.println(m.toString()); 
		}
	}

	@Override
	public void run() {
		sentEmail(mailTo, cc,subject, msgContent);	
	}
}

下面用到发送邮件的地方，比如一些事件完成调用这个类

List<String> mailTo=new ArrayList();//要发送的目的邮箱
List<String> cc=new ArrayList();//抄送的邮箱

.....这里把邮箱的List放入mailTo和cc 

比如mailTo.add(xx@gmail.com);

String subject="xxxxx";//邮件的主题
  StringBuffer sb=new StringBuffer(); //邮件的内容

sb.append("xxxxx");

 NewEmailSender sender=new NewEmailSender(mailTo, cc, subject, sb.toString()); //参数分别为目标邮箱，抄送邮箱，主题，内容
 Thread t = new Thread(sender);  //定义线程  发送
 t.start();

这样就可以发送了，默认是从配置文件里的邮箱给这个邮箱发
