Java Mail学习整理

1.加载jar包
        mail.jar ，    

        commons-email-X.X.jar ，    

        activation.jar    

         <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>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.2</version>
        </dependency>

2.写个mail对象
        package com.study.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.写个工具类            

        package com.study.service.impl;
        import org.apache.commons.mail.EmailException;
        import org.apache.commons.mail.HtmlEmail;
        import org.apache.log4j.Logger;    

        import com.study.bean.Mail;
        /**
         * Created by QD-ZHENGWP on 16/07/19.
         *
         * 邮件发送工具实现类
         *
         */
        public class MailUtill {    

            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;
                }
            }
        }    

4.测试            

         public static void test(){
                Mail mail = new Mail();
                mail.setHost("smtp.163.com"); // 设置邮件服务器
                mail.setSender("[email protected]");//发件人
                mail.setReceiver("[email protected]"); // 接收人
                mail.setUsername("[email protected]"); // 登录账号,一般都是和邮箱名一样吧
                mail.setPassword("haokaili1124"); // 发件人邮箱的登录密码
                mail.setSubject("hello大家好");
                mail.setMessage("我是小小小小鸟");
                new MailUtill().send(mail);    

            }
