http://java.sun.com/products/javamail/index.html
核心类与接口
javax.mail.Session
javax.mail.Message
javax.mail.Address
javax.mail.Authenticator
javax.mail.Transport
javax.mail.Store
javax.mail.Folder
-----------------------------------------------------
1 加载javamail的jar包
2 编写处理类
public class SendMail {
public static void mian(String[] args){
Properties props=new Properties();
Session session=Session.getInstance(props,null);
props.put("mail.host", "127.0.0.1");//接收邮件的地址
props.put("mail.transport.protocol", "smtp");//传输邮件的协议
Message message=new MimeMessage(session);
try {
message.setFrom(new InternetAddress("ywj_sh110@163.com"));//设定发件人
message.setRecipient(Message.RecipientType.TO, new InternetAddress("ywj_316@163.com"));//设定收件人
message.setSubject("你好吗?");//设标题
message.setText("javamail发送邮件测试");//设内容
Transport.send(message);//发送信息
} catch (AddressException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
---------------------------------------------------
Apache Commons Email组件
1 加载javamail的jar包和Apache Commons Email的jar包
2 编写servlet的处理类
public class SendCommMail extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
SimpleEmail email=new SimpleEmail();//生成SimpleEmail对象
email.setHostName("smtp.sina.com");//生成邮件
email.setAuthentication("web08", "web2008");//建立用户
email.setCharset("UTF-8");//邮件内容编码
try {
email.setFrom(request.getParameter("from"));//发件人
email.addTo(request.getParameter("to"));//收件人
email.setMsg(request.getParameter("context"));//内容
email.send();//发送邮件
request.setAttribute("sendmail.message", "邮件发送成功!");
} catch (Exception e) {
e.printStackTrace();
request.setAttribute("sendmail.message", "邮件发送不成功!");
}
request.getRequestDispatcher("/sendResult.jsp").forward(request, response);
}
}
3 配置web.xml文件
4 页面
----------------------------------------------------------------------
带附件的邮件
1 1 加载javamail的jar包,Apache Commons Email的jar包和fileUpLoad
2 2 编写servlet的处理类
public class SendCommMail extends HttpServlet {
private ServletContext sc;//ServletContext定义了一系列方法用于与相应的servlet容器通信
private String savePath;
File file;
private Map<String,String> parameters=new HashMap<String,String>();//存页面信息
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
file=this.doAtta(request);
MultiPartEmail email=new MultiPartEmail();//生成SimpleEmail对象
email.setHostName("smtp.163.com");//生成邮件
email.setAuthentication("ywj_316", "1234567890");//建立用户
email.setCharset("UTF-8");//邮件内容编码
try {
email.setFrom(parameters.get("from"));//发件人
email.addTo(parameters.get("to"));//收件人
email.setMsg(parameters.get("context"));//内容
email.setSubject(parameters.get("title"));//主题
if(file!=null){
EmailAttachment attachment=new EmailAttachment();//附什对象
attachment.setPath(file.getParent());//附件路径
attachment.setDescription(EmailAttachment.ATTACHMENT);//附件类型
attachment.setName(file.getName());//附件名称
email.attach(attachment);
}
System.out.println("ssssssssssssssssssssssssssssssssssss");
email.send();//发送邮件
request.setAttribute("sendmail.message", "邮件发送成功!");
} catch (Exception e) {
e.printStackTrace();
request.setAttribute("sendmail.message", "邮件发送不成功!");
}
request.getRequestDispatcher("/sendResult.jsp").forward(request, response);
}
public File doAtta(HttpServletRequest request)throws ServletException,IOException{
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
try {
List items = upload.parseRequest(request);
for (int i = 0; i < items.size(); i++) {
FileItem item = (FileItem) items.get(i);
if (item.isFormField()) {
parameters.put(item.getFieldName(), item.getString("UTF-8"));
System.out.println(item.getFieldName());
System.out.println(item.getString("UTF-8"));
} else {
if (item.getName() != null && !item.getName().equals("")) {
File temFile = new File(item.getName());
file = new File(sc.getRealPath("/") + savePath,
temFile.getName());
item.write(file);
request.setAttribute("upload.message", "上传文件成功!");
} else {
request.setAttribute("upload.message", "没有上传文件成功!");
}
}
}
} catch (Exception e) {
e.printStackTrace();
request.setAttribute("upload.message", "没有上传文件成功!");
}
return file;
}
public void init(ServletConfig config) throws ServletException {
savePath = config.getInitParameter("savePath");//得到初始化信息
sc = config.getServletContext();//得到ServletContext接口的实例
}
}
3 配置web.xml文件
<servlet>
<servlet-name>SendCommMail</servlet-name>
<servlet-class>com.webs.SendCommMail</servlet-class>
<init-param>
<param-name>savePath</param-name>
<param-value>uploads</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>SendCommMail</servlet-name>
<url-pattern>/servlet/sendMail</url-pattern>
</servlet-mapping>
4 页面
<body>
发送邮件的程序<br>
<form action="servlet/sendMail" name="form1" enctype="multipart/form-data" method="post">
收件人:<input type="text" name="to"/><br>
发件人:<input type="text" name="from"/><br>
主题:<input type="text" name="title"/><br>
附件:<input type="file" name="file"/><br>
