Javamail发送邮件
是码农没错了 人气:0一. 使用QQ邮箱作为smtp邮件服务器发送邮件
步骤1.开启QQ邮箱的POP3/SMTP服务:
开启后会得到一个16位授权码, 作为第三方使用邮件服务器的登录凭证.
注意: 修改邮箱密码后, 授权码会失效, 需要重新获取.
步骤2: 编写配置文件applicationContext-email.xml(此处使用xml配置方式):
<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd" default-lazy-init="false"> <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host"> <!-- qq的SMTP邮箱服务器地址, 若使用163网易则改为:smtp.163.com --> <value>smtp.qq.com</value> </property> <!-- <property name="port"> SMTP邮箱服务器端口(465或587), 建议不要配置, 使用默认就行 <value>建议不要配置!!博主配置反而发布出去!!</value> </property> --> <property name="javaMailProperties"> <props> <prop key="mail.smtp.auth">true</prop> <!-- 连接超时时间 --> <prop key="mail.smtp.timeout">25000</prop> </props> </property> <!-- 你的邮箱账号 --> <property name="username"> <value>xxxxxxx@qq.com</value> </property> <!-- 16位授权码, 注意不是登录密码! --> <property name="password"> <value>qazcrslpoghcbahh</value> </property> <property name="defaultEncoding"> <value>UTF-8</value> </property> </bean> <bean id="simpleMailMessage" class="org.springframework.mail.SimpleMailMessage"> <!-- 发件人信息, 需要和上面username值一样 --> <property name="from" value="xxxxxxx@qq.com" /> </bean> </beans>
步骤3: 编写测试类:
package emailtest; import java.util.Date; import javax.annotation.Resource; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.util.StringUtils; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext-email.xml") public class EmailTest { @Resource private JavaMailSender javaMailSender; @Resource private SimpleMailMessage simpleMailMessage; @Test public void sendMail() throws MessagingException{ sendMail("xxxxx@163.com","验证码:6666","密码找回"); } public void sendMail(String email, String content, String subject) throws MessagingException { MimeMessage message = javaMailSender.createMimeMessage(); MimeMessageHelper messageHelper; messageHelper = new MimeMessageHelper(message, true, "UTF-8"); messageHelper.setFrom(StringUtils.trimAllWhitespace(simpleMailMessage.getFrom())); messageHelper.setTo(email); messageHelper.setSubject(subject); messageHelper.setText(content, true); messageHelper.setSentDate(new Date()); // 发送邮件 javaMailSender.send(messageHelper.getMimeMessage()); } }
二. 使用网易邮箱作为smtp邮件服务器发送邮件
1.相似的, 先打开网易邮箱的POP3/SMTP服务, 设置授权码.
2.修改上述applicationContext.xml中配置信息:
服务器地址改为smtp.163.com
username更改为你的网易邮箱账号
password则是你在开启POP3/SMTP服务时设置的授权码
from的值和username值一样.
