使用spring框架发送email

Spring邮件抽象层的主要包为 org.springframework.mail 。它包括了发送电子邮件的主要接口 MailSender ，和 值对象 SimpleMailMessage ，它封装了简单邮件的属性如 from ,  to , cc ,  subject , text 。 包里还包含一棵以 MailException 为根的checked Exception继承树，它们提供了对底层邮件系统异常的高级别抽象。 要获得关于邮件异常层次的更丰富的信息，请参考Javadocs。

为了使用JavaMail中的一些特色, 比如MIME类型的信件, Spring提供了MailSender的一个子接口, 即org.springframework.mail.javamail.JavaMailSender。Spring还提供了一个回调接口org.springframework.mail.javamail.MimeMessagePreparator, 用于准备JavaMail的MIME信件。

这里简单的介绍了如何使用spring发送各种形式的邮件以及配置。

1、在src目录下建立mail.properties文件里边包含一下内容

mail.host=smtp.exmail.qq.com(建议使用这个，如果使用smtp.qq.com可能会出现安全认证的问题
mail.username=你的邮箱名
mail.password=你的邮箱密码
mail.from=发送方的邮箱

2、使用spring配置

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns= "http://www.springframework.org/schema/beans" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" xmlns:p= "http://www.springframework.org/schema/p" xsi:schemaLocation= "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd" > <!-- 加载Properties文件 --> <bean id= "configurer" class= "org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" > <property name= "locations" > <list> <value>classpath:mail.properties </value> </list> </property> </bean> <bean id= "mailMessage" class= "org.springframework.mail.SimpleMailMessage" > <property name= "from" > <value>${mail.from} </value> </property> <!-- 查看SimpleMailMessage源码还可以注入标题,内容等 --> </bean> <!-- 申明JavaMailSenderImpl对象 --> <bean id= "mailSender" class= "org.springframework.mail.javamail.JavaMailSenderImpl" > <property name= "defaultEncoding" value= "UTF-8" /> <property name= "host" value= "${mail.host}" /> <property name= "username" value= "${mail.username}" /> <property name= "password" value= "${mail.password}" /> <property name= "javaMailProperties" > <props> <!-- 设置认证开关 --> <prop key= "mail.smtp.auth" >true </prop> <!-- 启动调试开关 --> <prop key= "mail.debug" >true </prop> <!-- 设置发送延时 --> <prop key= "mail.smtp.timeout" >0 </prop> </props> </property> </bean> </beans>

3、发送简单的邮件

package mail ; import javax.mail.MessagingException ; import org.springframework.context.ApplicationContext ; import org.springframework.context.support.ClassPathXmlApplicationContext ; import org.springframework.mail.MailSender ; import org.springframework.mail.SimpleMailMessage ; /** * 本类测试邮件发送Html形式 * * @author Eternity_._ * */ public class SingleMailSend { static ApplicationContext actx = new ClassPathXmlApplicationContext ( "applicationContext.xml" ); static MailSender sender = ( MailSender ) actx . getBean ( "mailSender" ); static SimpleMailMessage mailMessage = ( SimpleMailMessage ) actx . getBean ( "mailMessage" ); public static void main ( String args []) throws MessagingException { mailMessage . setSubject ( "你好" ); mailMessage . setText ( "这个是一个通过Spring框架来发送邮件的小程序" ); mailMessage . setTo ( "9197****[email protected]" ); sender . send ( mailMessage ); } }

4、发送带有图片的邮件，以嵌入HTML的方式

package springmail ; import java.io.File ; import javax.mail.MessagingException ; import javax.mail.internet.MimeMessage ; import org.springframework.context.ApplicationContext ; import org.springframework.context.support.ClassPathXmlApplicationContext ; import org.springframework.core.io.FileSystemResource ; import org.springframework.mail.javamail.JavaMailSenderImpl ; import org.springframework.mail.javamail.MimeMessageHelper ; public class SpringAttachedImageMail { public static void main ( String [] args ) throws MessagingException { ApplicationContext ctx = new ClassPathXmlApplicationContext ( "applicationContext.xml" ); JavaMailSenderImpl sender = ( JavaMailSenderImpl ) ctx . getBean ( "mailSender" ); MimeMessage mailMessage = sender . createMimeMessage (); MimeMessageHelper messageHelper = new MimeMessageHelper ( mailMessage , true ); messageHelper . setFrom ( "9197****[email protected]" ); messageHelper . setTo ( "9197****[email protected]" ); messageHelper . setSubject ( "测试邮件中嵌套图片!！" ); // true 表示启动HTML格式的邮件 messageHelper . setText ( "<html><head></head><body><h1>hello!!spring image html mail</h1>" + "<a href=http://www.baidu.com>baidu</a>" + "<img src=cid:image/></body></html>" , true ); FileSystemResource img = new FileSystemResource ( new File ( "单.png" )); messageHelper . addInline ( "image" , img ); //跟cid一致 sender . send ( mailMessage ); System . out . println ( "邮件发送成功..." ); } }

5、发送带有附件的邮件

package springmail ; import java.io.File ; import javax.mail.MessagingException ; import javax.mail.internet.MimeMessage ; import org.springframework.context.ApplicationContext ; import org.springframework.context.support.ClassPathXmlApplicationContext ; import org.springframework.core.io.FileSystemResource ; import org.springframework.mail.javamail.JavaMailSenderImpl ; import org.springframework.mail.javamail.MimeMessageHelper ; public class SpringAttachedImageMail { public static void main ( String [] args ) throws MessagingException { ApplicationContext ctx = new ClassPathXmlApplicationContext ( "applicationContext.xml" ); JavaMailSenderImpl sender = ( JavaMailSenderImpl ) ctx . getBean ( "mailSender" ); MimeMessage mailMessage = sender . createMimeMessage (); MimeMessageHelper messageHelper = new MimeMessageHelper ( mailMessage , true ); messageHelper . setFrom ( "9197****[email protected]" ); messageHelper . setTo ( "9197****[email protected]" ); messageHelper . setSubject ( "测试邮件中嵌套图片!！" ); // true 表示启动HTML格式的邮件 messageHelper . setText ( "<html><head></head><body><h1>hello!!spring image html mail</h1>" + "<a href=http://www.baidu.com>baidu</a>" + "<img src=cid:image/></body></html>" , true ); FileSystemResource img = new FileSystemResource ( new File ( "单.png" )); messageHelper . addAttachment ( "单.png" , file ); //添加到附件 sender . send ( mailMessage ); System . out . println ( "邮件发送成功..." ); } }

6、如果使用的是QQ邮箱的话建议把这几项都选上，不然可能调试不能通过。
