1、如果是想用HTML做发送的内容及布局的话，那就不要用js
2、如果在发送邮件的时候将HTML文件作为附件的话，那是可以有js的
Java发送邮件需要用到JavaMail，先到Oracle官网上下载好最新版本的JavaMail（刚才看了一下，最新是1.5.3），把下载的这个jar文件放到classpath里（如果是Web项目，就放到WEB-INF/lib目录下。
JavaMail主要支持发送纯文本的和html格式的邮件。
java发送html格式邮件的具体实现：
import javax.mail.internet.InternetAddressimport javax.mail.internet.MimeMessage
import javax.mail.internet.MimeUtility
import javax.mail.Session
import javax.mail.MessagingException
import javax.mail.Transport
public class SendHtmlMail {
public static void sendMessage(String smtpHost,
String from, String to,
String subject, String messageText)
throws MessagingException,java.io.UnsupportedEncodingException {
// Step 1: Configure the mail session
System.out.println("Configuring mail session for: " + smtpHost)
java.util.Properties props = new java.util.Properties()
props.setProperty("mail.smtp.auth", "true")//指定是否需要SMTP验证
props.setProperty("mail.smtp.host", smtpHost)//指定SMTP服务器
props.put("mail.transport.protocol", "smtp")
Session mailSession = Session.getDefaultInstance(props)
mailSession.setDebug(true)//是否在控制台显示debug信息
// Step 2: Construct the message
System.out.println("Constructing message - from=" + from + " to=" + to)
InternetAddress fromAddress = new InternetAddress(from)
InternetAddress toAddress = new InternetAddress(to)
MimeMessage testMessage = new MimeMessage(mailSession)
testMessage.setFrom(fromAddress)
testMessage.addRecipient(javax.mail.Message.RecipientType.TO, toAddress)
testMessage.setSentDate(new java.util.Date())
testMessage.setSubject(MimeUtility.encodeText(subject,"gb2312","B"))
testMessage.setContent(messageText, "text/htmlcharset=gb2312")
System.out.println("Message constructed")
// Step 3: Now send the message
Transport transport = mailSession.getTransport("smtp")
transport.connect(smtpHost, "webmaster", "password")
transport.sendMessage(testMessage, testMessage.getAllRecipients())
transport.close()
System.out.println("Message sent!")
}
public static void main(String[] args) {
String smtpHost = "localhost"
String from = "[email protected]"
String to = "[email protected]"
String subject = "html邮件测试" //subject javamail自动转码
StringBuffer theMessage = new StringBuffer()
theMessage.append("<h2><font color=red>这倒霉孩子</font></h2>")
theMessage.append("<hr>")
theMessage.append("<i>年年失望年年望</i>")
try {
SendHtmlMail.sendMessage(smtpHost, from, to, subject, theMessage.toString())
}
catch (javax.mail.MessagingException exc) {
exc.printStackTrace()
}
catch (java.io.UnsupportedEncodingException exc) {
exc.printStackTrace()
}
}
}
发送的邮件内容<Table><tr><td>邮件内容</td></tr></table>接收的时候会自动转成HTML页面的 发送的时候就像页面排版的内容一样的发过去就好了setContent(参数)，里面的字符串要是完成的html代码，"<html><head></head><body></body></html>"，这种，我只写了个大概，反正就是要是完整的html代码，祝你成功
