springboot2.1.0、email简单使用

一）、在pom.xml中引入

<!-- json处理jar -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.49</version>
</dependency>
        
<!-- email jar -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

 

二）、email一些邮箱常用配置，配置在application.properties文件中

邮箱常用配置配置、163服务器地址(smtp.163.com)、126服务器地址(smtp.126.com)、qq服务器地址(smtp.qq.com)

spring.mail.host=smtp.xxx.com #邮箱服务器地址
spring.mail.username=xxx.163.com #用户名
spring.mail.password=aaa #开启POP3之后设置的客户端授权码
spring.mail.default-encoding=UTF-8 #编码

spring.mail.properties.mail.smtp.connectiontimeout=60000 #可选
spring.mail.properties.mail.smtp.timeout=60000 #可选
spring.mail.properties.mail.smtp.writetimeout=60000 #可选

 

三）创建一个邮箱VO类和一个Controller类

package com.oysept.springboot.vo;

import java.io.Serializable;

public class EmailVO implements Serializable {
    
    private static final long serialVersionUID = 1L;

    // 发送人
    private String from;
    // 接收人
    private String to;
    // 标题
    private String subject;
    // 内容
    private String content;
    // 附件路径
    private String filePath;
	
    public String getFrom() {return from;}
    public void setFrom(String from) {this.from = from;}

    public String getTo() {return to;}
    public void setTo(String to) {this.to = to;}

    public String getSubject() {return subject;}
    public void setSubject(String subject) {this.subject = subject;}

    public String getContent() {return content;}
    public void setContent(String content) {this.content = content;}

    public String getFilePath() {return filePath;}
    public void setFilePath(String filePath) {this.filePath = filePath;}
}

测试代码：

package com.oysept.springboot.controller;

import java.io.File;

import javax.mail.internet.MimeMessage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.http.MediaType;

import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;

        message.setFrom(this.from);
        message.setTo(emailVO.getTo());
        message.setSubject(emailVO.getSubject());
        message.setText(emailVO.getContent());
		
        try {

            return null;
        }
        return emailVO;
    }
	
    /**

    @RequestMapping(value = "/sendHtmlMail", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    @ResponseBody
    public MimeMessageHelper sendHtmlMail(@RequestBody EmailVO emailVO){
		
        MimeMessage message = mailSender.createMimeMessage();
		
        MimeMessageHelper helper = null;
        try {
            helper = new MimeMessageHelper(message, true);
            helper.setFrom(this.from);
            helper.setTo(emailVO.getTo());
            helper.setSubject(emailVO.getSubject());

            long end = System.currentTimeMillis();
            LOGGER.info("结束-----富文本邮件发送,耗费" + (end-begin)+"毫秒");
        } catch (Exception e) {
            LOGGER.info("富文本邮件发送,error!", e);
            return null;
        }
        return helper;
    }
	
    /**
     * 发送带附件的邮件
     * @param emailVO
     * @return
     */
    	@RequestMapping(value = "/sendAttachmentsMail", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    @ResponseBody
    public MimeMessageHelper sendAttachmentsMail(@RequestBody EmailVO emailVO){
		
        MimeMessage message = mailSender.createMimeMessage();
		
        MimeMessageHelper helper = null;
        try {

            // 附件
            FileSystemResource resource = new FileSystemResource(new File(emailVO.getFilePath()));

            return null;
        }
        return helper;
    }
}

 

四）、测试对应的方法，下面用postman举例

其它接口测试都一样的，就不举例了。
