javaMail发送电子邮件的方法,自己总结了个步骤:
1、首先需要获取发送邮件的Session对象
Session session = Session.getDefaultInstance(properties,authorcator);
2、根据session对象,获取待发送的邮件消息
MimeMessage mimeMessage = new MimeMessage(session);
3、设置发件人,收件人,标题,邮件内容,附件,发送时间等;
4、利用Transport发送邮件
以下是居然的实现代码:
package com.china.test.mail; import java.util.Properties; /** * 发送邮件需要使用的基本信息 * @author dove * */ public class MailSenderInfo { // 发送邮件的服务器的IP private String mailServerHost; // 发送邮件的服务器的端口 private String mailServerPort = "25"; // 邮件发送者的地址 private String fromAddress; // 邮件接收者的地址 private String[] toAddress; // 邮件密送接收者的地址 private String[] toBlindCarbonCopyAddress; // 邮件抄送接收者的地址 private String[] toCarbonCopyAddress; // 登陆邮件发送服务器的用户名 private String userName; // 登陆邮件发送服务器的密码 private String password; // 是否需要身份验证 private boolean validate = false; // 邮件主题 private String subject; // 邮件的文本内容 private String content; // 邮件附件的文件名 private String[] attachFileNames; /** * 获得邮件会话属性 */ public Properties getProperties() { Properties pro = new Properties(); pro.put("mail.smtp.host", this.mailServerHost); pro.put("mail.smtp.port", this.mailServerPort); pro.put("mail.smtp.auth", validate ? "true" : "false"); return pro; } 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 String getFromAddress() { return fromAddress; } public void setFromAddress(String fromAddress) { this.fromAddress = fromAddress; } 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 getPassword() { return password; } public void setPassword(String password) { this.password = password; } public boolean isValidate() { return validate; } public void setValidate(boolean validate) { this.validate = validate; } public String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public String[] getAttachFileNames() { return attachFileNames; } public void setAttachFileNames(String[] attachFileNames) { this.attachFileNames = attachFileNames; } public String[] getToBlindCarbonCopyAddress() { return toBlindCarbonCopyAddress; } public void setToBlindCarbonCopyAddress(String[] toBlindCarbonCopyAddress) { this.toBlindCarbonCopyAddress = toBlindCarbonCopyAddress; } public String[] getToCarbonCopyAddress() { return toCarbonCopyAddress; } public void setToCarbonCopyAddress(String[] toCarbonCopyAddress) { this.toCarbonCopyAddress = toCarbonCopyAddress; } }
package com.china.test.mail; import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; /** * 身份验证器 * @author dove * */ public class MyAuthenticator extends Authenticator { private String username; private String password; public MyAuthenticator(){ } public MyAuthenticator(String username, String password) { this.username = username; this.password = password; } @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
3、发送邮件类
该类有两个功能,一个是发送普通文本邮件;一个是发送html邮件,两者的本质是相同的,mime类型有所区别而已,具体请看代码:
