Java发送邮件--web.xml配置，Java代码配置

　　前言：我目前总结的使用java发送邮件的方式有两种，分别是在spring框架xml配置文件使用bean标签，另一种方法是把发送功能封装成一个对象，废话不多说上代码，边看代码边讲解，希望对需要的人能有帮助。

一、使用xml配置文件发送邮件

第一步：新建一个xml文件起名为emailSender.xml (名称是随意的，后面的代码和名称对应上就可以)

emailSender.xml 内容如下

<?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:aop="http://www.springframework.org/schema/aop"

    xmlns:jee="http://www.springframework.org/schema/jee"

    xmlns:context="http://www.springframework.org/schema/context"

    xmlns:lang="http://www.springframework.org/schema/lang"

    xmlns:security="http://www.springframework.org/schema/security"

     xmlns:mvc="http://www.springframework.org/schema/mvc"

        xsi:schemaLocation="http://www.springframework.org/schema/beans

       http://www.springframework.org/schema/beans/spring-beans-4.1.xsd

       http://www.springframework.org/schema/aop

       http://www.springframework.org/schema/aop/spring-aop-4.1.xsd

       http://www.springframework.org/schema/tx

       http://www.springframework.org/schema/tx/spring-tx-4.1.xsd

       http://www.springframework.org/schema/context

       http://www.springframework.org/schema/context/spring-context-4.1.xsd

       http://www.springframework.org/schema/jee

       http://www.springframework.org/schema/jee/spring-jee-4.1.xsd

       http://www.springframework.org/schema/lang

       http://www.springframework.org/schema/lang/spring-lang-4.1.xsd

       http://www.springframework.org/schema/mvc

       http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd

       http://www.springframework.org/schema/security

       http://www.springframework.org/schema/security/spring-security-3.2.xsd">    

     <!-- ******************************************************************** -->

    <!-- Spring 3.0 configuration -->

    <!-- ******************************************************************** -->

     <mvc:annotation-driven/>

    <!-- Allows for mapping the DispatcherServlet to "/" by forwarding static resource requests to the container's default Servlet -->

    <mvc:default-servlet-handler/>

    <!-- 配置邮箱发射器 -->

    <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

     <property name="host">

          <value>smtp.qq.com</value>

     </property>

     <property name="port">

         <!-- Error using port 465, so use port 587 -->

          <value>587</value>

     </property>

     <property name="javaMailProperties">

            <props>

              <prop key="mail.smtp.auth">true</prop>

              <prop key="mail.smtp.timeout">80000</prop>

              <!--

                <prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>

                <prop key="mail.smtp.socketFactory.port">465</prop>

              -->

            </props>

        </property>

     <property name="username">

      <value>这里填写发送邮箱号</value>

     </property>

     <property name="password">

      <value>这里填写密码（qq邮箱填写授权码）</value>

     </property>

    </bean>

</beans>

第二步：写java代码（可以发送html邮件哦，只需要修改一处代码就OK啦！！！）

import javax.mail.MessagingException;

import javax.mail.internet.MimeMessage;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.mail.javamail.MimeMessageHelper;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.ResponseBody;

@Controller

public class SendEmailController {

    @RequestMapping(value = "/sendEmail", method = RequestMethod.POST)

    @ResponseBody

    public void sendEmail(){

        try {

            System.out.println("read to send");

            //引入mailSender.xml配置文件

            ApplicationContext ctx = new ClassPathXmlApplicationContext("mailSender.xml");

            //从配置文件中创建java邮件发射器

            JavaMailSender sender = (JavaMailSender)ctx.getBean("javaMailSender");

            //创建发送消息对象

            MimeMessage msg = sender.createMimeMessage();

            //创建发送消息帮助对象，utf-8编码

            MimeMessageHelper helper = new MimeMessageHelper(msg,true,"utf-8");

            //设置发送人邮箱

            helper.setFrom("xxxxxx@qq.com");

            //设置收件人邮箱

            helper.setTo("xxxxxx@163.com");

            //设置邮箱主题

            helper.setSubject("测试邮件");

            //设置邮箱内容--纯文本格式

            helper.setText("tets this is a spring mvc email");
　　　　　　　//我想发送一封html邮件，把  helper.setText("")  修改成  msg.setContent("邮件内容", "text/html;charset = utf-8");

            System.out.println("Is sending...");

            //发送邮件

            sender.send(msg);

            System.out.println("email send ok");

        } catch (MessagingException e) {

            System.out.println("send fail");

            e.printStackTrace();

        }

    }

}

二、第二种方法：直接使用java代码配置

package com.ccpit.p4.dispatch.web;

import java.util.Properties;

import javax.mail.Authenticator;

import javax.mail.MessagingException;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMessage.RecipientType;

public class sendMail {

    public static void main(String[] args) throws MessagingException{

        // 创建Properties 类用于记录邮箱的一些属性

        final Properties props = new Properties();

        // 表示SMTP发送邮件，必须进行身份验证

        props.put("mail.smtp.auth", "true");

        //此处填写SMTP服务器

        props.put("mail.smtp.host", "smtp.qq.com");

        //端口号，QQ邮箱给出了两个端口，但是另一个我一直使用不了，所以就给出这一个587

        props.put("mail.smtp.port", "587");

        // 此处填写你的账号

        props.put("mail.user", "xxxxxx@qq.com");

        // 此处的密码就是前面说的16位STMP口令

        props.put("mail.password", "xxxxxx");

        // 构建授权信息，用于进行SMTP进行身份验证

        Authenticator authenticator = new Authenticator() {

            protected PasswordAuthentication getPasswordAuthentication() {

                // 用户名、密码

                String userName = props.getProperty("mail.user");

                String password = props.getProperty("mail.password");

                return new PasswordAuthentication(userName, password);

            }

        };

        // 使用环境属性和授权信息，创建邮件会话

        Session mailSession = Session.getInstance(props, authenticator);

        // 创建邮件消息

        MimeMessage message = new MimeMessage(mailSession);

        // 设置发件人

        InternetAddress form = new InternetAddress(

                props.getProperty("mail.user"));

        try {

            message.setFrom(form);

        } catch (MessagingException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        // 设置收件人的邮箱

        InternetAddress to = new InternetAddress("xxxxxx@163.com");

        message.setRecipient(RecipientType.TO, to);

        // 设置邮件标题

        message.setSubject("测试邮件");

        // 设置邮件的内容体

        message.setContent("这是一封测试邮件", "text/html;charset=UTF-8");

        // 最后当然就是发送邮件啦

        Transport.send(message);

    }

}
