SSM整合框架实现发送邮件功能

Posted 2020-12-18 lin02

一.导入发送邮件的依赖

  <!--    发送邮件jar包-->
    <!--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>

二.发送邮件的账号开启POP3/SMTP/IMAP/SMIP服务

 

三.spring-mybatis.xml配置文件中添加发送邮件所需的配置信息

 <!--邮件配置-->
    <context:property-placeholder location="classpath:email.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>
    </bean>

四.创建email.properties      接上 配置邮件接口  

#服务器主机名 smtp.xx.com
mail.smtp.host=smtp.qq.com
mail.smtp.username=开启服务的邮箱号@qq.com
#密码/客户端授权码
mail.smtp.password=开启服务的邮箱号的密钥
#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

五.在控制层测试

package com.mvo.controller;

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.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;

/**
 * 测试邮件发送controller
 */
@Controllerpublic class SendMailController {
    @Autowired
    private JavaMailSender javaMailSender;//在spring中配置的邮件发送的bean

    @RequestMapping("sendMailTest")
    public Object sendMailTest(){
        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("/email.properties"));
            from = prop.get("mail.smtp.username")+"";
            mMessageHelper=new MimeMessageHelper(mMessage,true);
            mMessageHelper.setFrom(from);//发件人邮箱
            mMessageHelper.setTo("收件人邮箱号@qq.com");//收件人邮箱
            mMessageHelper.setSubject("ssm框架测试邮件发送");//邮件的主题
            mMessageHelper.setText("<p>这是使用spring,springmvc,mybatis整合框架的邮件功能发送的一封邮件,测试</p>",true);//邮件的文本内容，true表示文本以html格式打开
            File file=new File("C:\\Users\\lcl\\Pictures\\Saved Pictures\\blog.csdn.net_Mr__Viking_article_details_81090046.png");//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("QQ截图20200721221932.png", 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";
    }
}
