步骤1：pom.xml添加依赖项
1 <!--mail--> 2 3 <dependency> 4 <groupId>javax.mail</groupId> 5 <artifactId>mailapi</artifactId> 6 <version>1.4.2</version> 7 </dependency> 8 9 <dependency> 10 <groupId>javax.mail</groupId> 11 <artifactId>mail</artifactId> 12 <version>1.4.2</version> 13 </dependency>
步骤2：封装一个工具类(参考下面的代码)
注:BaseBean里其实没啥东西，就一个protected Logger logger，方便子类可以直接使用，大家参考时，可根据需要去掉BeseBean继承
1 package com.cnblogs.yjmyzz.utils; 2 3 import com.cnblogs.yjmyzz.domain.BaseBean; 4 import org.springframework.util.StringUtils; 5 6 import java.util.Properties; 7 8 import javax.mail.Message; 9 import javax.mail.MessagingException; 10 import javax.mail.Session; 11 import javax.mail.Transport; 12 import javax.mail.internet.InternetAddress; 13 import javax.mail.internet.MimeMessage; 14 import javax.mail.internet.MimeUtility; 15 16 /** 17 * 邮件发送工具类 18 */ 19 public class MailUtil extends BaseBean { 20 21 private MimeMessage message; 22 private Session session; 23 private Transport transport; 24 private String smtpHost = ""; 25 private int smtpPort = 25; 26 private String senderUserName = ""; 27 private String senderPassword = ""; 28 29 public MailUtil(Properties properties, boolean debug) { 30 this.smtpHost = properties.getProperty("mail.smtp.host"); 31 this.smtpPort = Integer.parseInt(properties.getProperty("mail.smtp.port")); 32 this.senderUserName = properties.getProperty("mail.sender.username"); 33 this.senderPassword = properties.getProperty("mail.sender.password"); 34 session = Session.getInstance(properties); 35 session.setDebug(debug);//开启后有调试信息 36 message = new MimeMessage(session); 37 } 38 39 /** 40 * 发送邮件 41 * 42 * @param subject 邮件主题 43 * @param mailBody 邮件内容 44 * @param senderNickName 发件人NickName 45 * @param receiveUser 收件人地址 46 * @param ccReceiveUser 抄送地址 47 * @param bccReceiveUser 密送地址 48 */ 49 public void sendEmail(String subject, String mailBody, String senderNickName, 50 String receiveUser, String ccReceiveUser, String bccReceiveUser, Boolean isHtmlFormat) { 51 try { 52 // 发件人 53 InternetAddress from = null; 54 if (StringUtils.isEmpty(senderNickName)) { 55 from = new InternetAddress(senderUserName); 56 } else { 57 from = new InternetAddress(MimeUtility.encodeWord(senderNickName) + " <" + senderUserName + ">"); 58 } 59 message.setFrom(from); 60 61 // 收件人 62 InternetAddress to = new InternetAddress(receiveUser); 63 message.setRecipient(Message.RecipientType.TO, to); 64 65 //抄送人 66 if (!StringUtils.isEmpty(ccReceiveUser)) { 67 InternetAddress cc = new InternetAddress(ccReceiveUser); 68 message.setRecipient(Message.RecipientType.CC, cc); 69 } 70 71 //密送人 72 if (!StringUtils.isEmpty(bccReceiveUser)) { 73 InternetAddress bcc = new InternetAddress(bccReceiveUser); 74 message.setRecipient(Message.RecipientType.BCC, bcc); 75 } 76 77 message.setSubject(subject); 78 String content = mailBody.toString(); 79 80 if (isHtmlFormat) { 81 message.setContent(content, "text/html;charset=UTF-8"); 82 } else { 83 message.setContent(content, "text/plain;charset=UTF-8"); 84 } 85 message.saveChanges(); 86 transport = session.getTransport("smtp"); 87 transport.connect(smtpHost, smtpPort, senderUserName, senderPassword); 88 transport.sendMessage(message, message.getAllRecipients()); 89 90 logger.debug(senderUserName + " 向 " + receiveUser + " 发送邮件成功！"); 91 92 } catch (Exception e) { 93 e.printStackTrace(); 94 logger.error("sendEmail失败！", e); 95 } finally { 96 if (transport != null) { 97 try { 98 transport.close(); 99 } catch (MessagingException e) { 100 e.printStackTrace(); 101 logger.error("sendEmail->transport关闭失败！", e); 102 } 103 } 104 } 105 } 106 107 }
步骤3：配置
a) 属性文件mail.properties
1 mail.smtp.host=smtp.qq.com 2 mail.smtp.port=25 3 mail.smtp.auth=true 4 mail.sender.username=xxx@qq.com 5 mail.sender.password=***
b) spring配置注入
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" 4 xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation=" 7 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd 8 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 9 http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd 10 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 11 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd" 12 default-autowire="byName"> 13 14 <bean id="mailProperties" 15 class="org.springframework.beans.factory.config.PropertiesFactoryBean"> 16 <property name="location" 17 value="classpath:mail.properties"/> 18 </bean> 19 20 <bean id="mailUtil" class="com.cnblogs.yjmyzz.utils.MailUtil"> 21 <constructor-arg index="0" ref="mailProperties"/> 22 <constructor-arg index="1" value="false"/> 23 </bean> 24 25 </beans>
测试代码：
1 @Test 2 public void testSendMail() { 3 ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-context.xml"); 4 MailUtil mailUtil = ctx.getBean(MailUtil.class); 5 mailUtil.sendEmail("骚年，崛起吧，人类需要你!", "<font color=red>骚年:</font><h1>快去拯救地球吧！</h1>", "菩提树上的杨过", "aaa@126.com", "bbb@infosky.com.cn", "ccc@sjtu.edu.cn", true); 6 ((ClassPathXmlApplicationContext) ctx).close(); 7 }
