Mail實體類

package com.bam.model;public class Mail {private String toUsers;private String subject;private String content;private String personal; }

SendMailSevice類

package com.bam.service;import javax.mail.MessagingException; import java.io.File; import java.io.UnsupportedEncodingException; import java.util.List;public interface SendMailSevice {/*** * @param toUser 發送人* @param subject 標題* @param text 內容* @param personal 發送人名稱* @param file 文件* @throws Exception*/void sendMailFile(String toUser, String subject, String text,String personal, File file) throws Exception; }

SendMailSeviceImpl 實現類

package com.bam.service.impl;import com.hbyh.bam.service.SendMailSevice; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service;import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import java.io.File; import java.io.UnsupportedEncodingException;@Service public class SendMailSeviceImpl implements SendMailSevice {@Autowiredprivate JavaMailSender javaMailSender;@Value("${spring.mail.username}")private String serverMail;public void sendMailFile(String toUser, String subject, String text,String personal, File file) throws MessagingException, UnsupportedEncodingException {MimeMessage message = javaMailSender.createMimeMessage();MimeMessageHelper helper = new MimeMessageHelper(message, true);helper.setFrom(serverMail,personal);helper.setTo(toUser);helper.setSubject(subject);helper.setText(text!=null?text:"", true);if(file!=null){//獲取文件名稱String filepathname=file.getName();//添加附件helper.addAttachment(filepathname, file);//附件}javaMailSender.send(message);} }

MailSocketFactory配置類

package com.bam.config.email; import javax.net.SocketFactory; import javax.net.ssl.SSLContext; import javax.net.ssl.SSLSocketFactory; import javax.net.ssl.TrustManager; import java.io.IOException; import java.net.InetAddress; import java.net.Socket; import com.bam.config.email.MailTrustManager;/*** email配置*/ public class MailSocketFactory extends SSLSocketFactory {private SSLSocketFactory factory;public MailSocketFactory() {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 MailSocketFactory();}@Overridepublic Socket createSocket() throws IOException {return factory.createSocket();}@Overridepublic Socket createSocket(Socket socket, String s, int i, boolean flag) throws IOException {return factory.createSocket(socket, s, i, flag);}@Overridepublic Socket createSocket(InetAddress inaddr, int i, InetAddress inaddr1, int j) throws IOException {return factory.createSocket(inaddr, i, inaddr1, j);}@Overridepublic Socket createSocket(InetAddress inaddr, int i) throws IOException {return factory.createSocket(inaddr, i);}@Overridepublic Socket createSocket(String s, int i, InetAddress inaddr, int j) throws IOException {return factory.createSocket(s, i, inaddr, j);}@Overridepublic Socket createSocket(String s, int i) throws IOException {return factory.createSocket(s, i);}@Overridepublic String[] getDefaultCipherSuites() {return factory.getDefaultCipherSuites();}@Overridepublic String[] getSupportedCipherSuites() {return factory.getSupportedCipherSuites();} }

MailTrustManager配置類

package com.bam.config.email; import javax.net.ssl.X509TrustManager; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; /*** email配置*/ public class MailTrustManager implements X509TrustManager {@Overridepublic void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic X509Certificate[] getAcceptedIssuers() {return new X509Certificate[0];} }

#####最后可以使用,此操作避免阿里云的25端口未開啟,創建的ssl協議格式發送郵件,可批量發送附件
