该类实现了较完整的邮件发送功能,包括以HTML格式发送,添加附件和抄送人。下面是具体的代码:

先写个简单的mail对象

package com.shadow.mvc.vo;

import java.io.Serializable;

/**
* Mail属性实体
*
* @author shadow
*
*/
@SuppressWarnings("serial")
public class Mail implements Serializable { public static final String ENCODEING = "UTF-8"; private String host; // 服务器地址 private String sender; // 发件人的邮箱 private String receiver; // 收件人的邮箱 private String name; // 发件人昵称 private String username; // 账号 private String password; // 密码 private String subject; // 主题 private String message; // 信息(支持HTML) public String getHost() {
return host;
} public void setHost(String host) {
this.host = host;
} public String getSender() {
return sender;
} 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;
} }

然后就写个工具类

package com.shadow.extras.util;

import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
import org.apache.log4j.Logger; import com.shadow.mvc.vo.Mail; /**
* 邮件发送工具实现类
*
* @author shadow
* @create 2013/07/12
*/
public class MailUtil { protected final Logger logger = Logger.getLogger(getClass()); public boolean send(Mail mail) {
// 发送email
HtmlEmail email = new HtmlEmail();
try {
// 这里是SMTP发送服务器的名字:163的如下:"smtp.163.com"
email.setHostName(mail.getHost());
// 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();
if (logger.isDebugEnabled()) {
logger.debug(mail.getSender() + " 发送邮件到 " + mail.getReceiver());
}
return true;
} catch (EmailException e) {
e.printStackTrace();
logger.info(mail.getSender() + " 发送邮件到 " + mail.getReceiver()
+ " 失败");
return false;
}
} }

最后写个main方法测试下

public static void main(String[] args) {
Mail mail = new Mail();
mail.setHost("smtp.163.com"); // 设置邮件服务器,如果不用163的,自己找找看相关的
mail.setSender("shadowsick@163.com");
mail.setReceiver("shadowsick@163.com"); // 接收人
mail.setUsername("shadowsick@163.com"); // 登录账号,一般都是和邮箱名一样吧
mail.setPassword("xxxxx"); // 发件人邮箱的登录密码
mail.setSubject("aaaaaaaaa");
mail.setMessage("bbbbbbbbbbbbbbbbb");
new MailUtil().send(mail);
}
