java 发送 mail 纯文本发送和html格式发送

一：需要引入mail maven jar包

<!--邮件发送包--><dependency><groupId>javax.mail</groupId><artifactId>mail</artifactId><version>1.4.7</version></dependency>

二：代码示例

package textAnalysis.dto;/*** Created by 草帽boy on /12/8.*/public class MailInfo {//邮箱服务器 如private String host ;//用户邮箱 如**@163private 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@为例 /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

package textAnalysis.util;import textAnalysis.dto.MailInfo;import javax.mail.*;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeBodyPart;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeMultipart;import java.util.Date;import java.util.Properties;/*** Created by 草帽boy on /12/8.*/public class MailSendUtil {private final static String host = ""; //163的服务器private final static String formName = "YYYXXX@";//你的邮箱private final static String password = "***********"; //授权码private final static String replayAddress = "YYYXXX@"; //你的邮箱public static void sendHtmlMail(MailInfo info)throws Exception{info.setHost(host);info.setFormName(formName);info.setFormPassword(password); //网易邮箱的授权码~不一定是密码info.setReplayAddress(replayAddress);Message message = getMessage(info);// MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象Multipart mainPart = new MimeMultipart();// 创建一个包含HTML内容的MimeBodyPartBodyPart html = new MimeBodyPart();// 设置HTML内容html.setContent(info.getContent(), "text/html; charset=utf-8");mainPart.addBodyPart(html);// 将MiniMultipart对象设置为邮件内容message.setContent(mainPart);Transport.send(message);}public static void sendTextMail(MailInfo info) throws Exception {info.setHost(host);info.setFormName(formName);info.setFormPassword(password); //网易邮箱的授权码~不一定是密码info.setReplayAddress(replayAddress);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.auth", "true");p.setProperty("mail.smtp.user", info.getFormName());p.setProperty("mail.smtp.pass", info.getFormPassword());// 根据邮件会话属性和密码验证器构造一个发送邮件的sessionSession session = Session.getInstance(p, new Authenticator(){protected PasswordAuthentication getPasswordAuthentication() {return new PasswordAuthentication(p.getProperty("mail.smtp.user"),p.getProperty("mail.smtp.pass"));}});session.setDebug(true);Message message = new MimeMessage(session);//消息发送的主题message.setSubject(info.getSubject());//接受消息的人message.setReplyTo(InternetAddress.parse(info.getReplayAddress()));//消息的发送者message.setFrom(new InternetAddress(p.getProperty("mail.smtp.user"),"余高峰"));// 创建邮件的接收者地址，并设置到邮件消息中message.setRecipient(Message.RecipientType.TO,new InternetAddress(info.getToAddress()));// 消息发送的时间message.setSentDate(new Date());return message ;}}

测试

@Testpublic void send(){String mail = "mmmmmmm@"; //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

采用的Junit的方式测试的采用 sendHtmlMai l的结果是
