要完成Java群发邮件功能,首先须加入mail.jar和activation.jar这两个包
下面是邮件的例子: import java.io.File; import java.util.Properties; import java.util.Vector; import javax.mail.internet.MimeUtility; /** * 发送邮件的信息类 * @author 仇志鹏 * @version 2016.10.19 * */ public class MailSenderInfo { // 发送邮件的服务器的IP和端口 private String mailServerHost; 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; // 登陆邮件发送服务器的用户名和密码 private String userName; 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 fileName = “” ; //附件文件集合 private Vector file = new Vector() ; /** * 获得邮件会话属性 * @return */ 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”); return p; } public String getMailServerHost() { return mailServerHost;
