标题：Spring通过Gmail SMTP服务器MailSender发送电子邮件

Spring提供了一个有用的“org.springframework.mail.javamail.JavaMailSenderImpl”类，通过JavaMail API 简化邮件发送过程。这里有一个项目中使用Spring “JavaMailSenderImpl”通过Gmail SMTP服务器发送电子邮件。

1. Spring邮件发件人

Java 类使用 Spring 的 MailSender 接口发送电子邮件。

File : MailMail.java

package com.yiibai.common;

import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

public class MailMail
{
	private MailSender mailSender;
	
	public void setMailSender(MailSender mailSender) {
		this.mailSender = mailSender;
	}
	
	public void sendMail(String from, String to, String subject, String msg) {

		SimpleMailMessage message = new SimpleMailMessage();
		
		message.setFrom(from);
		message.setTo(to);
		message.setSubject(subject);
		message.setText(msg);
		mailSender.send(message);	
	}
}

2. bean配置文件

配置 mailSender bean 并指定Gmail的SMTP服务器电子邮件的详细信息。

Gmail的配置细节(这里是墙，该翻的翻) – http://mail.google.com/support/bin/answer.py?hl=en&answer=13287

File : Spring-Mail.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
	<property name="host" value="smtp.gmail.com" />
	<property name="port" value="587" />
	<property name="username" value="yiibai.com@gmail.com" />
	<property name="password" value="password" />
		
	<property name="javaMailProperties">
	   <props>
       	      <prop key="mail.smtp.auth">true</prop>
       	      <prop key="mail.smtp.starttls.enable">true</prop>
       	   </props>
	</property>
</bean>
	
<bean id="mailMail" class="com.yiibai.common.MailMail">
	<property name="mailSender" ref="mailSender" />
</bean>
	
</beans>

运行它

package com.yiibai.common;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App 
{
    public static void main( String[] args )
    {
    	ApplicationContext context = 
             new ClassPathXmlApplicationContext("Spring-Mail.xml");
    	 
    	MailMail mm = (MailMail) context.getBean("mailMail");
        mm.sendMail("from@no-spam.com",
    		   "to@no-spam.com",
    		   "Testing123", 
    		   "Testing only \n\n Hello Spring Email Sender");
        
    }
}
