1、导包

<dependency>    <groupId>commons-email</groupId>    <artifactId>commons-email</artifactId>    <version>1.1</version></dependency><dependency>    <groupId>javax.activation</groupId>    <artifactId>activation</artifactId>    <version>1.1</version></dependency>

非maven项目需要mail.jar， commons-email-X.X.jar， activation.jar
2、创建一个Mail实体

package com.study.base.common.bean;import java.io.Serializable;/** * Mail属性实体 * */@SuppressWarnings("serial")public class Mail {    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;    }}

3、导入Mail工具类

package com.study.base.common.util;import org.apache.commons.mail.EmailException;import org.apache.commons.mail.HtmlEmail;import org.apache.log4j.Logger;import com.study.base.common.bean.Mail;/** * Mail工具类 */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","smtp.sina.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());            //setContent方法可发送带有html标签的数据            //email.setContent(mail.getMessage(),"text/html; charset=utf-8");            // 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;        }    }}

4、发送邮件

/** * 发送验证码 * @param userBean * @return */@Override@Transactional(readOnly = false)public boolean accountCheck(SysUserBean userBean){    Mail mail = new Mail();    mail.setHost("smtp.163.com"); // 设置邮件服务器    mail.setSender("1234567@163.com");//发件人    mail.setReceiver("1794822268@qq.com"); // 接收人    mail.setUsername("1234567@163.com"); // 登录账号,一般都是和邮箱名一样吧    mail.setPassword("123456"); // 发件人邮箱的登录密码    mail.setSubject("验证码");    mail.setMessage("邮件内容");    new MailUtil().send(mail);    return true;};
