Java SMTP

Spring中javaMail通过SMTP发送邮件

Sending e-mail with Spring MVC

http://jiangzhenghua.iteye.com/blog/333944

1、如果是maven项目，需要引入依赖包

[html] view plain copy
在CODE上查看代码片派生到我的代码片

    <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.4.4</version>
    </dependency>

2、在项目加载的basic.xml中，配置两个bean：JavaMailSenderImpl和SimpleMailMessage，在后续发送邮件中通过这两个类进行发送。

[html] view plain copy

    <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
           <property name="host" >
            <value>----</value>
           </property>
           <property name="port" >
            <value type="java.lang.Integer">----</value>
           </property>
           <property name="protocol">
            <value>smtps</value>
           </property>
           <property name="username">
            <value>----</value>
           </property>
           <property name="password">
            <value>----</value>
           </property>
           
           <property name="javaMailProperties">
               <props>
                   
                   <prop key="mail.smtps.auth">true</prop>
                   <prop key="mail.smtp.ssl.enable">true</prop>
                <prop key="mail.transport.protocol">smtps</prop>
              </props>
           </property>
       </bean>

       <bean id="simpleMailMessage" class="org.springframework.mail.SimpleMailMessage">
        <property name="from">
            <value>${notify_service.smtp_mail.username}</value>
        </property>
       </bean>

3、在实际发送的class里面调用
[java] view plain copy
在CODE上查看代码片派生到我的代码片

    private MailSender mailSender;
        private SimpleMailMessage simpleMailMessage;

    //初始化mailSender 和SimpleMailMessage 两个对象

    simpleMailMessage.setTo(sendTo);
    simpleMailMessage.setSubject(subject);
    simpleMailMessage.setText(content);
    mailSender.send(simpleMailMessage);

另外如果是发送HTML格式的邮件参考：http://www.blogjava.Net/fancydeepin/archive/2012/06/12/spring-smtp-mail-with-attachment_maven3.html

[java] view plain copy

    import javax.mail.MessagingException;
    import javax.mail.internet.MimeMessage;

    import org.springframework.mail.SimpleMailMessage;
    import org.springframework.mail.javamail.JavaMailSender;
    import org.springframework.mail.javamail.MimeMessageHelper;

    private JavaMailSender javaMailSender;
        private MimeMessage mimeMessage;
        private MimeMessageHelper mimeMessageHelper;
        private SimpleMailMessage simpleMailMessage;

    try {

[java] view plain copy

                         mimeMessage = javaMailSender.createMimeMessage();
    mimeMessageHelper = new MimeMessageHelper(mimeMessage,true,"GBK");
    mimeMessageHelper.setFrom(simpleMailMessage.getFrom());
    mimeMessageHelper.setTo(sendTo);
    mimeMessageHelper.setSubject(subject);
    mimeMessageHelper.setText(content);
    javaMailSender.send(mimeMessage);
     catch (MessagingException e) {
    e.printStackTrace();

4、如果不用Spring直接用javamail发送

[java] view plain copy
在CODE上查看代码片派生到我的代码片

    import javax.mail.internet.InternetAddress;
    import javax.mail.internet.MimeMessage;
    import javax.mail.internet.MimeUtility;
    import javax.mail.Session;
    import javax.mail.MessagingException;
    import javax.mail.Transport;

    public class SendHtmlMail {
       public void sendmail(){

            //创建邮件发送类 JavaMailSender
            //用于发送基本的文本邮件信息（不能包括附件，及图片）
            JavaMailSender sender = new JavaMailSenderImpl();


            //设置邮件服务主机
            ((JavaMailSenderImpl)sender).setHost("smtp.sohu.com");
            //发送者邮箱的用户名
            ((JavaMailSenderImpl)sender).setUsername("userName");
            //发送者邮箱的密码
            ((JavaMailSenderImpl)sender).setPassword("password");

            //配置文件，用于实例化java.mail.session
            Properties pro = System.getProperties();

            //登录SMTP服务器,需要获得授权，网易163邮箱新近注册的邮箱均不能授权。
            //测试 sohu 的邮箱可以获得授权
            pro.put("mail.smtp.auth", "true");
            pro.put("mail.smtp.socketFactory.port", "25");
            pro.put("mail.smtp.socketFactory.fallback", "false");

            //通过文件获取信息
            ((JavaMailSenderImpl)sender).setJavaMailProperties(pro);


            //创建基本邮件信息
            MailMessage mailMessage = new SimpleMailMessage();

            //发送者地址，必须填写正确的邮件格式，否者会发送失败
            mailMessage.setFrom("******@sohu.com");
            //邮件主题
            mailMessage.setSubject("测试邮件");
            //邮件内容，简单的邮件信息只能添加文本信息
            mailMessage.setText("测试");
            //邮件接收者的邮箱地址
            mailMessage.setTo("******@qq.com");


            //发送邮件，参数可以是数组
            //sender.send(SimpleMailMessage[])
            sender.send((SimpleMailMessage)mailMessage);

        }
    }

5、javaMail发送HTML个是的邮件

[java] view plain copy
在CODE上查看代码片派生到我的代码片

    public void sendMimeMail() throws MessagingException{

            //创建邮件发送类 JavaMailSender
            //用于发送多元化邮件，包括附件，图片，html 等
            JavaMailSender mimeMailSender = new JavaMailSenderImpl();

            //设置邮件服务主机
            ((JavaMailSenderImpl)mimeMailSender).setHost("smtp.sohu.com");
            //发送者邮箱的用户名
            ((JavaMailSenderImpl)mimeMailSender).setUsername("userName");
            //发送者邮箱的密码
            ((JavaMailSenderImpl)mimeMailSender).setPassword("password");

            //配置文件，用于实例化java.mail.session
            Properties pro = System.getProperties();

            //登录SMTP服务器,需要获得授权，网易163邮箱新近注册的邮箱均不能授权。
            //测试 sohu 的邮箱可以获得授权
            pro.put("mail.smtp.auth", "true");
            pro.put("mail.smtp.socketFactory.port", "25");
            pro.put("mail.smtp.socketFactory.fallback", "false");

            ((JavaMailSenderImpl)mimeMailSender).setJavaMailProperties(pro);

            //创建多元化邮件
            MimeMessage mimeMessage = ((JavaMailSenderImpl)mimeMailSender).createMimeMessage();

            //创建 mimeMessage 帮助类，用于封装信息至 mimeMessage
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true, "GBK");

            //基本信息

            //发送者地址，必须填写正确的邮件格式，否者会发送失败
            helper.setFrom("*******@sohu.com");
            //邮件主题
            helper.setSubject("测试邮件");
            //邮件内容，简单的邮件信息只能添加文本信息
            helper.setText("测试");
            //邮件接收者的邮箱地址
            helper.setTo("******@qq.com");


            //多元化信息

            //添加HTML 信息
            File myPicture = new File("C:\\Documents and Settings\\Administrator\\桌面\\kz2.jpg");

            //如果是html代码，boolean 的参数用该为true
            helper.setText("<html><head><meta http-equiv="+"Content-Type"+" content="+"text/html; charset=gb2312"+"></head><body><h1>新书快递通知</h1>你的新书快递申请已推送新书，请到<a href=''>空间"
                        + "</a>中查看<br><img src='cid:myPicture'></body></html>", true);

            //添加图片至HTML 代码中
            helper.addInline("myPicture", myPicture);

            //添加附件
            File file = new File("C:\\Documents and Settings\\Administrator\\桌面\\validate.jar");
            helper.addAttachment("picture", myPicture);
            helper.addAttachment("picture", file);

            ((JavaMailSender)mimeMailSender).send(mimeMessage);

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