㈠ java发送html格式邮件是否能有js
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：
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeMessage;
importjavax.mail.internet.MimeUtility;
importjavax.mail.Session;
importjavax.mail.MessagingException;
importjavax.mail.Transport;
publicclassSendHtmlMail{
publicstaticvoidsendMessage(StringsmtpHost,
Stringfrom,Stringto,
Stringsubject,StringmessageText)
throwsMessagingException,java.io.UnsupportedEncodingException{
//Step1:Configurethemailsession
System.out.println("Configuringmailsessionfor:"+smtpHost);
java.util.Propertiesprops=newjava.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");
SessionmailSession=Session.getDefaultInstance(props);
mailSession.setDebug(true);//是否在控制台显示debug信息
//Step2:Constructthemessage
System.out.println("Constructingmessage-from="+from+"to="+to);
InternetAddressfromAddress=newInternetAddress(from);
InternetAddresstoAddress=newInternetAddress(to);
MimeMessagetestMessage=newMimeMessage(mailSession);
testMessage.setFrom(fromAddress);
testMessage.addRecipient(javax.mail.Message.RecipientType.TO,toAddress);
testMessage.setSentDate(newjava.util.Date());
testMessage.setSubject(MimeUtility.encodeText(subject,"gb2312","B"));
testMessage.setContent(messageText,"text/html;charset=gb2312");
System.out.println("Messageconstructed");
//Step3:Nowsendthemessage
Transporttransport=mailSession.getTransport("smtp");
transport.connect(smtpHost,"webmaster","password");
transport.sendMessage(testMessage,testMessage.getAllRecipients());
transport.close();
System.out.println("Messagesent!");
}
publicstaticvoidmain(String[]args){
StringsmtpHost="localhost";
Stringfrom="[email protected]";
Stringto="[email protected]";
Stringsubject="html邮件测试";//subjectjavamail自动转码
StringBuffertheMessage=newStringBuffer();
theMessage.append("<h2><fontcolor=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.MessagingExceptionexc){
exc.printStackTrace();
}
catch(java.io.){
exc.printStackTrace();
}
}
}
