通过JAVA发送邮件--mail.jar

通过JAVA发送email. 需要下载mail.jar. 第4个java代码的些设置根据实际情况设置。

本例是针对goole邮件服务：google mail: smtp.gmail.com 465 需要启用ssl。 其他的可以网上参考。

1. MailSenderInfo

import java.util.Properties;

public class MailSenderInfo {

private String mailServerHost;

private String mailServerPort = "25";

private String fromAddress;

private String toAddress;

private String userName;

private String password;

private boolean validate = false;

private String subject;

private String content;

private String[] attachFileNames;

private boolean ssl;

final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";

public Properties getProperties() {

Properties p = new Properties();

p.put("mail.smtp.host", this.mailServerHost);

p.put("mail.smtp.port", this.mailServerPort);

p.put("mail.smtp.auth", validate ? "true" : "false");

if(ssl) p.put("mail.smtp.socketFactory.class", SSL_FACTORY);

return p;

}

public String getMailServerHost() {

return mailServerHost;

}

public void setMailServerHost(String mailServerHost) {

this.mailServerHost = mailServerHost;

}

public String getMailServerPort() {

return mailServerPort;

}

public void setMailServerPort(String mailServerPort) {

this.mailServerPort = mailServerPort;

}

public boolean isValidate() {

return validate;

}

public void setValidate(boolean validate) {

this.validate = validate;

}

public String[] getAttachFileNames() {

return attachFileNames;

}

public void setAttachFileNames(String[] fileNames) {

this.attachFileNames = fileNames;

}

public String getFromAddress() {

return fromAddress;

}

public void setFromAddress(String fromAddress) {

this.fromAddress = fromAddress;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public String getToAddress() {

return toAddress;

}

public void setToAddress(String toAddress) {

this.toAddress = toAddress;

}

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

public String getSubject() {

return subject;

}

public void setSubject(String subject) {

this.subject = subject;

}

public String getContent() {

return content;

}

public void setContent(String textContent) {

this.content = textContent;

}

public boolean isSsl() {

return ssl;

}

public void setSsl(boolean ssl) {

this.ssl = ssl;

}

}

2. MyAuthenticator

import javax.mail.Authenticator;

import javax.mail.PasswordAuthentication;

public class MyAuthenticator extends Authenticator {

String userName = null;

String password = null;

public MyAuthenticator() {

}

public MyAuthenticator(String username, String password) {

this.userName = username;

this.password = password;

}

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(userName, password);

}

}

mailMessage.setRecipient(Message.RecipientType.TO, to);

// 设置邮件消息的主题

mailMessage.setSubject(mailInfo.getSubject());

// 设置邮件消息发送的时间

mailMessage.setSentDate(new Date());

// MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象
