一、邮箱的应用在实际的Java开发过程中，也是非常常见的。我这里就是写了一个简单的邮箱发送功能。
二、邮箱的基本配置，使用的是JavaMailSender的提供的方式来实现邮件的发送
1）qq邮箱的配置（说明一点目前qq邮箱的配置方式都是采用ssl的方式来实现的，非ssl的方式没有测试成功）
package com.troy.jpa.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import java.util.Properties;
@Configuration
public class MailConfiguration {
@Bean
public JavaMailSender javaMailSender() {
//设置JavaMail的基本数据
JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
//host官方查询
javaMailSender.setHost("smtp.qq.com");
//端口465ssl
javaMailSender.setPort(465);
//设置账户,密码
javaMailSender.setUsername("409546297@qq.com");
javaMailSender.setPassword("密码");
//认证数据配置，ssl方式需要加入认证方式
Properties properties = new Properties();
properties.setProperty("mail.host", "smtp.qq.com");
properties.setProperty("mail.transport.protocol", "smtp");
properties.setProperty("mail.smtp.auth", "true");
properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.smtp.port", "465");
properties.setProperty("mail.smtp.socketFactory.port", "465");
javaMailSender.setJavaMailProperties(properties);
return javaMailSender;
}
}
注意：这里的密码不是我们一般登录的密码，而是授权码
![]()
2）163邮箱有2中配置方式
a、ssl的的连接方式
package com.troy.jpa.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import java.util.Properties;
@Configuration
public class MailConfiguration {
@Bean
public JavaMailSender javaMailSender() {
JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
javaMailSender.setHost("smtp.163.com");
javaMailSender.setPort(465);
javaMailSender.setUsername("账号");
javaMailSender.setPassword("密码");
Properties properties = new Properties();
properties.setProperty("mail.host", "smtp.163.com");
properties.setProperty("mail.transport.protocol", "smtp");
properties.setProperty("mail.smtp.auth", "true");
properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.smtp.port", "465");
properties.setProperty("mail.smtp.socketFactory.port", "465");
javaMailSender.setJavaMailProperties(properties);
return javaMailSender;
}
}
b、非ssl的连接方式
package com.troy.jpa.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
@Configuration
public class MailConfiguration {
@Bean
public JavaMailSender javaMailSender() {
JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
javaMailSender.setHost("smtp.163.com");
javaMailSender.setPort(25);
javaMailSender.setUsername("账号");
javaMailSender.setPassword("密码");
return javaMailSender;
}
}
3）这个是采用注解的方式，自己也可以采用xml的配置方式，自己随意
4）应用，邮件的发送
package com.troy.jpa.util;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
public class MailUtil {
public static void main(String[] args) {
sendMail("收件人邮箱","test","test");
}
public static void sendMail(String mail, String title, String text) {
//加载容器
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring/spring-mvc.xml");
//获取bean
JavaMailSender javaMailSender = (JavaMailSender) context.getBean("javaMailSender");
//建立邮箱模板
SimpleMailMessage mailMessage = new SimpleMailMessage();
//设置发送人的账号
mailMessage.setFrom("发送人账号（和登录的账号一样）");
//设置接收人的账号
mailMessage.setTo(mail);
//设置主题
mailMessage.setSubject(title);
//设置内容
mailMessage.setText(text);
//发送邮件
javaMailSender.send(mailMessage);
}
}
