邮箱实体
import java.io.Serializable; public class Mail implements Serializable { private static final long serialVersionUID = -3562218214168975242L; public static final String ENCODEING = "UTF-8"; private String host; private String portNumber; private String sender; private String receiver; private String name; private String username; private String password; private String subject; private String message; public String getHost() { return host; } public void setHost(String host) { this.host = host; } public String getSender() { return sender; } public String getPortNumber() { return portNumber; } public void setPortNumber(String portNumber) { this.portNumber = portNumber; } public void setSender(String sender) { this.sender = sender; } public String getReceiver() { return receiver; } public void setReceiver(String receiver) { this.receiver = receiver; } public String getName() { return name; } public void setName(String name) { this.name = name; } 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 String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } } 工具类
import org.apache.commons.mail.EmailException; import org.apache.commons.mail.HtmlEmail; public class MailUtil { public boolean send(Mail mail) { //发送email对象 HtmlEmail email = new HtmlEmail(); try { //这里是SMTP发送服务器的名字 email.setHostName(mail.getHost()); //端口号不为空时,用户自定义的端口号为SMTP发送服务器端口号 if (!"".equals(mail.getPortNumber())) { email.setSSLOnConnect(true); email.setSslSmtpPort(mail.getPortNumber()); } //字符编码集的设置 email.setCharset(Mail.ENCODEING); //收件人的邮箱 email.addTo(mail.getReceiver()); //发送人的邮箱 email.setFrom(mail.getSender(), mail.getName()); // 如果需要认证信息的话，设置认证：用户名-密码。分别为发件人在邮件服务器上的注册名称和密码 email.setAuthentication(mail.getUsername(), mail.getPassword()); // 要发送的邮件主题 email.setSubject(mail.getSubject()); // 要发送的信息，由于使用了HtmlEmail，可以在邮件内容中使用HTML标签 email.setMsg(mail.getMessage()); // 发送 email.send(); return true; } catch (EmailException e) { e.printStackTrace(); return false; } } } 开始
import java.util.Random; public class SimpleEmailClient { public static void main(String[] args) throws InterruptedException { Mail mail = new Mail(); mail.setHost("smtp.qq.com"); // 设置邮件服务器,如果不用QQ邮箱的,自己找找看相关的 mail.setPortNumber("465"); // 设置邮件服务器端口号,默认25 mail.setSender("xxxx@qq.com"); // 发送人 mail.setName("杨大侠"); // 发送人昵称 mail.setSubject("好吃美味"); //发送主题 mail.setMessage("好吃美味"); //发送内容 mail.setUsername("xxxx@qq.com"); // 登录账号,一般都是和邮箱名一样 mail.setPassword("********"); // QQ邮箱登录第三方客户端时,密码框请输入“授权码”进行验证。其他的密码具体查看邮件服务器的说明 for (int i = 0; i < 1000; i++) { //Thread.sleep(2000); int max1 = 99999; int min1 = 10000; Random random = new Random(); int f = random.nextInt(max1)%(max1-min1+1) + min1; int max2 = 9999; int min2 = 1000; Random random2 = new Random(); int s = random2.nextInt(max2)%(max2-min2+1) + min2; String account = "" + f + "" + s + "@qq.com"; mail.setReceiver(account); // 接收人 System.out.println(account); if (new MailUtil().send(mail)) { System.out.println("发送成功"); } else { System.out.println("发送失败"); } } } }看完上述内容是否对您有帮助呢？如果还想对相关知识有进一步的了解或阅读更多相关文章，请关注编程网行业资讯频道，感谢您对编程网的支持。
