Spring中javaMail通过SMTP发送邮件

参考 http://www.blogjava.net/fancydeepin/category/51935.html

1、如果是maven项目，需要引入依赖包

<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。

	<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>
        <!-- SMTP服务器验证 -->
        <property name="javaMailProperties">
            <props>
                <!-- 验证身份 -->
                <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

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

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 {

                        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

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

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");  
    }
