1.首先引入Jar包支持

<!--spring支持-->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>5.0.0.RELEASE</version>
</dependency>
<!--邮件发送-->
<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>javax.mail</artifactId>
    <version>1.6.1</version>
</dependency>

2.配置xml文件

<!--邮件配置-->
<context:property-placeholder location="classpath:mail.properties" ignore-unresolvable="true"/>
<!--配置邮件接口-->
<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host" value="${mail.smtp.host}"/>
    <property name="username" value="${mail.smtp.username}"/>
    <property name="password" value="${mail.smtp.password}"/>
    <property name="defaultEncoding" value="${mail.smtp.defaultEncoding}"/>
    <property name="javaMailProperties">
        <props>
            <prop key="mail.smtp.auth">${mail.smtp.auth}</prop>
            <prop key="mail.smtp.timeout">${mail.smtp.timeout}</prop>
        </props>
    </property>

3.新建mail.properties文件

#服务器主机名 smtp.xx.com
mail.smtp.host=smtp.163.com
mail.smtp.username=huachun_w@163.com
#密码/客户端授权码
mail.smtp.password=xxxxxxxxxx
#编码字符
mail.smtp.defaultEncoding=utf-8
#是否进行用户名密码校验
mail.smtp.auth=true
#设置超时时间
mail.smtp.timeout=20000

4.配置一个测试类

package com.imooc.oa.quartz;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.SimpleMailMessage;
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.RestController;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
import java.io.IOException;
import java.util.Properties;
@Controller
@RequestMapping("/mail")
public class SendMailController {

    @Autowired
    private JavaMailSender javaMailSender;//在spring中配置的邮件发送的bean

    @RequestMapping("/send")
    public Object sendMail03(){
        MimeMessage mMessage=javaMailSender.createMimeMessage();//创建邮件对象
        MimeMessageHelper mMessageHelper;
        Properties prop = new Properties();
        String from;
        try {
            //从配置文件中拿到发件人邮箱地址
            prop.load(this.getClass().getResourceAsStream("/mail.properties"));
            from = prop.get("mail.smtp.username")+"";
            mMessageHelper=new MimeMessageHelper(mMessage,true);
            mMessageHelper.setFrom(from);//发件人邮箱
            mMessageHelper.setTo("huachun_w@163.com");//收件人邮箱
            mMessageHelper.setSubject("Spring的邮件发送");//邮件的主题
            mMessageHelper.setText("<p>这是使用spring的邮件功能发送的一封邮件</p><br/>" +
                    "<a href='https://blog.csdn.net/Mr__Viking'>打开我的博客主页</a><br/>" +
                    "<img src='fengye'>",true);//邮件的文本内容，true表示文本以html格式打开
            File file=new File("D:/图片/大雄.jpg");//在邮件中添加一张图片
            FileSystemResource resource=new FileSystemResource(file);
            mMessageHelper.addInline("fengye", resource);//这里指定一个id,在上面引用
            mMessageHelper.addAttachment("D:/图片/静香.jpg", resource);//在邮件中添加一个附件
            javaMailSender.send(mMessage);//发送邮件
        } catch (MessagingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "发送成功";
    }

}

有时候会出先544异常问题

解决方法：把MessagingException改成Exception就可以成功接到Exception。线程就不会阻塞。
