# java 发送 mail 纯文本发送和html格式发送 #

## 一：需要引入mail maven jar包 ##

<dependency>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
      <version>1.4.7</version>
    </dependency>

## 二：代码示例 ##

*  2.1 定义消息实体类

package textAnalysis.dto;
    
    /**

     */
    
    public class MailInfo {
        //邮箱服务器 如smtp.163.com
        private String host ;
        //用户邮箱 如**@163
        private String formName ;
        //用户授权码 不是用户名密码 可以自行查看相关邮件服务器怎么查看
        private String formPassword ;
        //消息回复邮箱
        private String replayAddress ;
        //发送地址
        private String toAddress ;
        //发送主题
        private String subject ;
        //发送内容
        private String content ;
    
        public String getHost() {
            return host;
        }
        public void setHost(String host) {
            this.host = host;
        }
        public String getFormName() {
            return formName;
        }
        public void setFormName(String formName) {
            this.formName = formName;
        }
        public String getFormPassword() {
            return formPassword;
        }
        public void setFormPassword(String formPassword) {
            this.formPassword = formPassword;
        }
        public String getReplayAddress() {
            return replayAddress;
        }
        public void setReplayAddress(String replayAddress) {
            this.replayAddress = replayAddress;
        }
        public String getToAddress() {
            return toAddress;
        }
        public void setToAddress(String toAddress) {
            this.toAddress = toAddress;
        }
        public String getSubject() {
            return subject;
        }
        public void setSubject(String subject) {
            this.subject = subject;
        }
        public String getContent() {
            return content;
        }
        public void setContent(String content) {
            this.content = content;
        }
    }

*  2.2 两种方式实现

> 首先你需要获取你的授权码，以@163.com为例 http://blog.csdn.net/hughnes/article/details/52070878  
> sendTextMail是纯文本发送  
> sendHtmlMail是HTML格式标签发送 这种方式可以识别html标签

            Message message = getMessage(info);
            //消息发送的内容
            message.setText(info.getContent());
    
            Transport.send(message);
        }
    
        private static Message getMessage(MailInfo info) throws Exception{
            final Properties p = System.getProperties() ;
            p.setProperty("mail.smtp.host", info.getHost());

            p.setProperty("mail.smtp.user", info.getFormName());

            // 根据邮件会话属性和密码验证器构造一个发送邮件的session
            Session session = Session.getInstance(p, new Authenticator(){

                }
            });
            session.setDebug(true);
            Message message = new MimeMessage(session);
            //消息发送的主题

            message.setSentDate(new Date());
    
    
            return message ;
        }
    }

## 测试 ##

@Test
    public void send(){
        String mail = "mmmmmmm@qq.com"; //发送对象的邮箱
        String title = "我有一句话跟你说";
        String content = "<div>你不在学校吗？</div><br/><hr/><div>记得28号来学校</div>";
        MailInfo info = new MailInfo();
        info.setToAddress(mail);
        info.setSubject(title);
        info.setContent(content);
        try {
    　　　　　　　//MailSendUtil.sendTextMail(info);
            MailSendUtil.sendHtmlMail(info);
        } catch (Exception e) {
            System.out.print("'"+title+"'的邮件发送失败！");
            e.printStackTrace();
        }
    }

采用的Junit的方式测试的采用 sendTextMail 的结果是
