Spring Boot配置ssl发送Email

1、引入依赖

在 pom.xml 文件中引入邮件配置：

    org.springframework.boot
    spring-boot-starter-mail

 

2、配置文件

# JavaMailSender 邮件发送的配置
spring.mail.host=smtp.china.com
[email protected]
spring.mail.password=123456
spring.mail.test-connection=false
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

# ssl 配置
spring.mail.port=465
spring.mail.default-encoding=UTF-8
spring.mail.properties.mail.smtp.ssl.enable=true
spring.mail.properties.mail.imap.ssl.socketFactory.fallback=false
spring.mail.properties.mail.smtp.ssl.socketFactory.class=com.fintech.modules.base.util.mail.MailSSLSocketFactory

注意：如果是https的，ssl配置必须有，如果不是可以不用加

3、代码实例

3.1、新建邮件entity

package com.fintech.modules.sms.common.dto;

import java.io.InputStream;
import java.io.Serializable;

/**
 * @Description: 邮件模型
 * @author lc
 * @date 2018年4月24日
 */
public class EmailModelDTO implements Serializable{

	/**
	 * 序列化
	 */
	private static final long serialVersionUID = -8840079326802564269L;
	
	/**
	 * 发送者
	 */
	private String from;
	
	/**
	 * 接受者
	 */
	private String[] to;
	
	/**
	 * 抄送
	 */
	private String[] cc;
	
	/**
	 * 邮件主题
	 */
	private String subject;
	
	/**
	 * 邮件内容
	 */
	private String text;
	
	/**
	 * 附件路径
	 */
	private String path;
	
	private InputStream is;
	
	public EmailModelDTO(String from, String[] to, String[] cc, String subject, String text, InputStream is){
		this.from = from;
		this.to = to;
		this.cc = cc;
		this.subject = subject;
		this.text = text;
		this.is = is;
	}

	public String getPath() {
		return path;
	}

	public void setPath(String path) {
		this.path = path;
	}

	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[] getCc() {
		return cc;
	}

	public void setCc(String[] cc) {
		this.cc = cc;
	}

	public static long getSerialversionuid() {
		return serialVersionUID;
	}

	public String getSubject() {
		return subject;
	}

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

	public String getText() {
		return text;
	}

	public void setText(String text) {
		this.text = text;
	}

	public InputStream getIs() {
		return is;
	}

	public void setIs(InputStream is) {
		this.is = is;
	}
	
}

3.2、创建邮件发送service

package com.fintech.modules.sms.common.service;

import javax.activation.DataSource;
import javax.mail.internet.MimeMessage;
import javax.mail.util.ByteArrayDataSource;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import com.fintech.modules.sms.common.dto.EmailModelDTO;

/**
 * @Description: 邮件发送service
 * @author lc
 * @date 2018年4月24日
 */
@Service
public class MailService {
	
	private static Logger logger = LoggerFactory.getLogger(MailService.class);
	
	@Autowired
	private JavaMailSender mailSender;
   
   /**
    * @Description: 发送简单文本邮件
    * @author lc
    */
   public void sendSimpleMail(EmailModelDTO email){
	   try {
			SimpleMailMessage message = new SimpleMailMessage();
			message.setFrom(email.getFrom());
			message.setTo(email.getTo());
			message.setSubject(email.getSubject());
			message.setText(email.getText());
			if(email.getCc() != null){
				message.setCc(email.getCc());
			}
			mailSender.send(message);
		} catch (Exception e) {
			logger.error("发送简单文本邮件异常！",e.getMessage());
		}
   }
   
   /**
    * @Description: 发送html邮件
    * @author lc
    */
   public void sendHtmlMail(EmailModelDTO email){
	   MimeMessage message = null;
	    try {
	        message = mailSender.createMimeMessage();
	        MimeMessageHelper helper = new MimeMessageHelper(message, true);
	        helper.setFrom(email.getFrom());
	        helper.setTo(email.getTo());
	        helper.setSubject(email.getSubject());
	        // 发送htmltext值需要给个true，不然不生效
	        helper.setText(email.getText(), true);
			if(email.getCc() != null){
				helper.setCc(email.getCc());
			}
			mailSender.send(message);
	    } catch (Exception e) {
	    	logger.error("发送简单文本邮件异常！",e.getMessage());
	    }
   }
   
   /**
    * @Description: 发送带附件的邮件
    * @author lc
    */
   public void sendAttachmentsMail(EmailModelDTO email){
	   MimeMessage message = null;
       try {
           message = mailSender.createMimeMessage();
           MimeMessageHelper helper = new MimeMessageHelper(message, true);
           helper.setFrom(email.getFrom());
           helper.setTo(email.getTo());
           helper.setSubject(email.getSubject());
           helper.setText(email.getText());
           if(email.getCc() != null){
        	   helper.setCc(email.getCc());
           }
           // 用流的形式发送附件邮件
           DataSource source = new ByteArrayDataSource(email.getIs(), "application/msexcel");  
           helper.addAttachment("短信发送失败记录.xls", source);
           mailSender.send(message);
       } catch (Exception e){
           logger.error("发送带附件的邮件异常！",e.getMessage());
       }
   }

}

3.3、读取配置文件中的发送人参数

//读取配置文件中的参数
@Value("${spring.mail.username}")
private String from; 

3.4、发送html邮件

@Autowired
private MailService mailService;

// 发送邮件
String[] to = null;
String subject = "短信发送失败通知（"+DateUtils.getTimeStampStr(new Date())+"）";
logger.info("短信平台通知邮件信息（邮件）：{}", content);
to = str.toArray(new String[str.size()]);
EmailModelDTO email = new EmailModelDTO(from, to, null, subject, content, null);
mailService.sendHtmlMail(email);

3.5、发送带有附件邮件

    /*
     * @Description: 导出
     * @author lc
     */
	public void exportExcel(List list, String sysCode){
		InputStream is = null;
		String[] headers_book = { "任务ID", "短信平台", "业务系统", "手机号", "错误码", "错误信息", "备注", "统计时间", "短信内容"};
		is = exportExcelService.exportExcel("短信发送失败记录",headers_book, list);
		String text = "各位好："+DateUtils.getReqDate(new Date())+"短信发送失败记录统计信息";
		String subject = "短信发送失败记录";
		String[] to = getEmailTo(sysCode);
//		String[] cc = getEmailCc(sysCode);
		EmailModelDTO email = new EmailModelDTO(from, to, null, subject, text, is);
		logger.info("短信发送状态邮件信息 {}", JSONArray.toJSON(email));
		mailService.sendAttachmentsMail(email);
	}

 

4、SSL配置代码

4.1、MailSSLSocketFactory

package com.fintech.modules.base.util.mail;

import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;

import javax.net.SocketFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;

/**
 * @Description: 邮件ssl
 * @author lc
 * @date 2018年5月31日
 */
public class MailSSLSocketFactory extends SSLSocketFactory {
    private SSLSocketFactory factory;

    public MailSSLSocketFactory() {
        try {
            SSLContext sslcontext = SSLContext.getInstance("TLS");
            sslcontext.init(null, new TrustManager[] { new MailTrustManager() }, null);
            factory = sslcontext.getSocketFactory();
        } catch (Exception ex) {
            // ignore
        }
    }

    public static SocketFactory getDefault() {
        return new MailSSLSocketFactory();
    }

    @Override
    public Socket createSocket() throws IOException {
        return factory.createSocket();
    }

    @Override
    public Socket createSocket(Socket socket, String s, int i, boolean flag) throws IOException {
        return factory.createSocket(socket, s, i, flag);
    }

    @Override
    public Socket createSocket(InetAddress inaddr, int i, InetAddress inaddr1, int j) throws IOException {
        return factory.createSocket(inaddr, i, inaddr1, j);
    }

    @Override
    public Socket createSocket(InetAddress inaddr, int i) throws IOException {
        return factory.createSocket(inaddr, i);
    }

    @Override
    public Socket createSocket(String s, int i, InetAddress inaddr, int j) throws IOException {
        return factory.createSocket(s, i, inaddr, j);
    }

    @Override
    public Socket createSocket(String s, int i) throws IOException {
        return factory.createSocket(s, i);
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return factory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return factory.getSupportedCipherSuites();
    }
}

 

4.2、MailTrustManager

 

package com.fintech.modules.base.util.mail;

import java.security.cert.X509Certificate;

import javax.net.ssl.X509TrustManager;

/**
 * @Description: 邮箱信证管理
 * @author lc
 * @date 2018年5月31日
 */
public class MailTrustManager implements X509TrustManager {
    public void checkClientTrusted(X509Certificate[] cert, String authType) {
        // everything is trusted
    }

    public void checkServerTrusted(X509Certificate[] cert, String authType) {
        // everything is trusted
    }

    public X509Certificate[] getAcceptedIssuers() {
        return new X509Certificate[0];
    }
}
