Apache commons email 使用过程中遇到的问题

apache-commons-email是对mail的一个封装，所以使用起来确实是很方便。特别的，官网上的tutorial也是极其的简单。但是我也仍然是遇到了没有解决的问题。

jar包的添加

• mail.jar && activation
• apache-commons-email.jar

一开始我没有添加上面的mail.jar ，然后就导致在编码的过程中，各种报错。

SimpleEmail实例

package email;

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.Email;
import org.apache.commons.mail.SimpleEmail;
import org.junit.Test;

public class SimpleEmailTest {

    @Test
    public void simple() throws Exception {
        final String HOSTNAME = "smtp.163.com";
        try {
            Email email = new SimpleEmail();
            email.setHostName(HOSTNAME);
            // email.setSmtpPort(465);
            email.setAuthenticator(new DefaultAuthenticator("15640SSS27", "XXXXXXX"));
            email.setSSLOnConnect(true);
            email.setFrom("[email protected]");
            email.setSubject("Test Mail By Commons-Emial");
            email.setMsg("Congratulations!\nYou have been admitted, so come here and join us ! :-)");
            email.addTo("[email protected]");
            email.send();
            System.out.println("邮件已成功发送！");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

带附件实例(图片和URL）

带图片的

@Test
    public void test() throws Exception {

        // 添加一个附件
        EmailAttachment attachment = new EmailAttachment();
        attachment.setPath("E:\\Code\\Java\\apache-commons-email\\src\\email\\be.png");
        attachment.setDisposition(EmailAttachment.ATTACHMENT);
        attachment.setDescription("one big beauty!");
        attachment.setName("beauty.png");

        // 实例化邮件
        MultiPartEmail email = new MultiPartEmail();
        email.setHostName("smtp.163.com");
        email.setAuthenticator(new DefaultAuthenticator("15 xxxx27", "gxuxxxxxxx4"));
        email.setSSLOnConnect(true);
        email.addTo("[email protected]");
        email.setFrom("[email protected]");
        email.setSubject("The Beauty Picture!");
        email.setMsg("Here is an email with a beauty!");

        // 把附件添加到邮件
        email.attach(attachment);

        // 发邮件
        email.send();

        System.out.println("邮件发送成功！");
    }

带URL的

@Test
    public void testURL() throws Exception {
        // 添加一个附件
                EmailAttachment attachment = new EmailAttachment();
                attachment.setURL(new URL("http://www.apache.org/images/asf_logo_wide.gif"));
                attachment.setDisposition(EmailAttachment.ATTACHMENT);
                attachment.setDescription("Apache Logo!");
                attachment.setName("ApacheLogo");

                // 实例化邮件
                MultiPartEmail email = new MultiPartEmail();
                email.setHostName("smtp.163.com");
                email.setAuthenticator(new DefaultAuthenticator("15ssss7", "gssssss4"));
                email.setSSLOnConnect(true);
                email.addTo("[email protected]");
                email.setFrom("[email protected]");
                email.setSubject("The Beauty Picture!");
                email.setMsg("Here is an email with a beauty!");

                // 把附件添加到邮件
                email.attach(attachment);

                // 发邮件
                email.send();

                System.out.println("邮件发送成功！");
    }

下面的是嵌入数据，但是却没能成功

package email;

import java.net.URL;

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.HtmlEmail;
import org.junit.Test;

public class WithHtmlTest {

    @Test
    public void sendHTMLFormattedEmail() throws Exception {
        try {
            // 实例化邮件
            HtmlEmail email = new HtmlEmail();
            email.setHostName("smtp.163.com");
            email.setAuthentication("[email protected]", "gdsadsaddsadsd");
            email.setSSLOnConnect(true);
            email.setSSL(true);
            email.addTo("[email protected]", "小郭");
            email.setFrom("[email protected]", "Me");
            email.setSubject("Test email with inline image");

            // embed the image and get the content id
            URL url = new URL("http://www.apache.org/images/asf_logo_wide.gif");
            String cid = email.embed(url, "Apache Logo!");

            // 设置html的内容
            email.setHtmlMsg("<html>The apache logo - <img src=\"cid:" + cid + "\"></html>");

            // 设置text的内容
            email.setTextMsg("Your email client doesn't support HTML messages!");

            // 发邮件
            email.send();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

报错的信息如下：
