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>
<tbody id="msg" style="display:none;" mce_style="display:none;">
。。。。。。<!--这里是需要显示或者隐藏的-->
</tbody>
js代码：
function showhidediv(id){
var sbtitle=document.getElementById(xx);
var unfold=document.getElementById("xx");
if(sbtitle){
if(sbtitle.style.display=='block'){
sbtitle.style.display='none';
unfold.innerHTML="+show";
}else{
sbtitle.style.display='block';
unfold.innerHTML="-hidden";
}
}
}
情形3 ajax实现选择某人后出现此人信息
function changeName(){
var em_id = document.getElementById("xx").value;
var urlStr = "<%=WEBPATH%>/changeName.fb?em_id="+em_id;
var xmlhttp;
if (window.XMLHttpRequest){ // code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else{ // code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
var mid = xmlhttp.responseText;
var buf = mid.split("$$");
var str=buf[1].split(";;");
var out = document.getElementById("xx");
out.options.length=0;
var ojobRole = document.getElementById("xx");
var owork = document.getElementById("owork");
for(var i=0;i<str.length-1;i++){
var proj=str[i].split(",");
out.options.add(new Option(proj[2],proj[0]));
ojobRole.value=proj[1];
owork.value=proj[3];
}
}
}
xmlhttp.open("get",urlStr,true);
xmlhttp.send(em_id);
}
是$$数据1;数据2;....$$
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
