spring来发EMAIL-优快云博客

spring对mail的支持是org.springframework.mail.MailSender接口来定义的，其中的org.springframework.mail.javamail.JavamailSenderImpl这个实现类提供了对javamail的支持，下面简单介绍其用法，首先看下不用注入的方法，再看用注入的方法。

1、发送简单邮件的例子
首先，我们要需要springframwork1.2.8中lib目录下的j2ee目录的activation.jar和mail.jar文件，将它们放到工程的lib目录下去。
发送一个简单邮件的例子如下
import org.springframework.mail.javamail.JavaMailSenderImpl; import org.springframework.mail.SimpleMailMessage; public class SimpleMailDemo { public static void main(String[] args) throws Exception { JavaMailSenderImpl senderImpl = new JavaMailSenderImpl(); // 设定 Mail Server senderImpl.setHost("mail.xxxxx"); //SMTP验证时，需要用户名和密码 senderImpl.setUsername("abc"); senderImpl.setPassword("defdf"); // 建立邮件讯息 SimpleMailMessage mailMessage = new SimpleMailMessage(); // 设定收件人、寄件人、主题与内文 mailMessage.setTo(hello@abc.com); mailMessage.setFrom(der@def.com); mailMessage.setSubject("Test"); mailMessage.setText("This is a test!!!"); // 传送邮件 senderImpl.send(mailMessage); System.out.println("邮件传送OK.."); } }

2、发送HTML格式的邮件
要发送HTML格式的话，要用org.springframework.mail.javamail.MimeMessageHelper来建立HTML邮件
import org.springframework.mail.javamail.JavaMailSenderImpl; import javax.mail.internet.MimeMessage; import org.springframework.mail.javamail.MimeMessageHelper; public class HTMLMailDemo { public static void main(String[] args) throws Exception { JavaMailSenderImpl senderImpl = new JavaMailSenderImpl(); // 设定 Mail Server senderImpl.setHost("mail.xxxxx"); //SMTP验证时，需要用户名和密码 senderImpl.setUsername("abc"); senderImpl.setPassword("defdf"); // 建立邮件讯息 MimeMessage mailMessage = senderImpl.createMimeMessage(); MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage); // 设定收件人、寄件人、主题与内文 messageHelper.setTo("xxx@your_mail_server.com"); messageHelper.setFrom("xxx@your_mail_server.com"); messageHelper.setSubject("Test"); messageHelper.setText( "<html><head></head><body><h1>Hello! Spring!" + "</h1></body></html>", true); // 传送邮件 senderImpl.send(mailMessage); System.out.println("邮件传送OK..."); } }

3、发送带附件的邮件
这时要用MimeMessageHelper的addAttachement()方法

import java.io.File; import org.springframework.mail.javamail.JavaMailSenderImpl; import javax.mail.internet.MimeMessage; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.javamail.MimeMessageHelper; public class AttachedFileDemo { public static void main(String[] args) throws Exception { JavaMailSenderImpl senderImpl = new JavaMailSenderImpl(); //SMTP验证时，需要用户名和密码 senderImpl.setUsername("abc"); senderImpl.setPassword("defdf"); MimeMessage mailMessage = senderImpl.createMimeMessage(); MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true); messageHelper.setTo("def@erer.net"); messageHelper.setFrom("bfg@tom.com"); messageHelper.setSubject("Test"); messageHelper.setText( "<html><head></head><body><h1>Hello! Spring!" + "</h1></body></html>", true); FileSystemResource file = new FileSystemResource( new File("d:/test.rar")); messageHelper.addAttachment("test.rar", file); senderImpl.send(mailMessage); System.out.println("OK"); } }

4、用注入的方式来配置邮件，和之前的差不多拉
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "spring-beans.dtd" > <beans> <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host"> <value>smtp.xxx.com</value> </property> <property name="javaMailProperties"> <props>  <prop key="mail.smtp.auth">true</prop> </props> </property> <property name="username"> <value>你的Email地址</value> </property> <property name="password"> <value>你的Email密码</value> </property> </bean>  <bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage"> <property name="to"> <value>收件人地址</value> </property> <property name="from"> <value>你的地址</value> </property> <property name="subject">  <value>A Spring Mail sender</value> </property> </bean>  <bean id="testMailSender" class="test.mail.TestSenderMail"> <property name="mailMessage"> <ref bean="mailMessage"/> </property> <property name="mailSender"> <ref bean="mailSender"/> </property> </bean> </beans>

上面的配置好以后就可以直接发送了
