写东西不喜欢多说，上代码，看的清楚明了，

1.maven仓库

<dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-email</artifactId>
      <version>1.5</version>
    </dependency>

2.导入架包

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.HtmlEmail;

3.代码

     HtmlEmail email = new HtmlEmail();
      email.setHostName( host );
      email.addTo( emailArray );
      email.setFrom( fromEmail, headContentFrom, "UTF-8" );
      email.setSubject( subject );
      email.setSslSmtpPort( smtpport );
      email.setAuthenticator( new DefaultAuthenticator( fromEmail, fromEmailPassword ) );
      email.setAuthentication( fromEmail, fromEmailPassword );
      email.setStartTLSEnabled( true );
      email.setCharset( "UTF-8" );
      email.setHtmlMsg( body );

      if( fileNameList.size() > 0 )
      {
        EmailAttachment attachment = null;
        for( int i = 0; i < fileNameList.size(); i ++ )
        {
          attachment = new EmailAttachment();
          attachment.setPath( fileNameList.get( i ) );
          attachment.setDisposition( EmailAttachment.ATTACHMENT );
          email.attach( attachment );
        }
      }
      System.out.println( email.send() );
