java之mail发送-白红宇

　　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;@Configurationpublic 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;@Configurationpublic 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;@Configurationpublic 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);    }}
