用Spring来发邮件

先来看看发送Email吧, 在Spring中发送Email是很简单的,使用Spring提高的MailSender和MailMessage就可以了,配置代码如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "spring-beans.dtd" >
<beans>
	<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host">
			<value>smtp.163.com</value>
		</property>
		<property name="javaMailProperties">
			<props>
				<!-- 如果要使用用户名和密码验证,这一步需要 -->
				<prop key="mail.smtp.auth">true</prop>
			</props>
		</property>
		<property name="username">
			<value>你的Email地址</value>
		</property>
		<property name="password">
			<value>你的Email密码</value>
		</property>
	</bean>
	
	<!-- 简单的message -->
	<bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage">
		<property name="to">
			<value>收件人地址</value>
		</property>
		<property name="from">
			<value>你的地址</value>
		</property>
		<property name="subject"> <!-- Email 标题 -->
			<value>A Spring Mail sender</value>
		</property>
	</bean>
	<!-- 测试发送的类 -->
	<bean id="testMailSender" class="test.mail.TestSenderMail">
		<property name="mailMessage">
			<ref bean="mailMessage" />
		</property>
		<property name="mailSender">
			<ref bean="mailSender" />
		</property>
	</bean>
</beans>

上面的配置好以后就可以直接发送了, 看看TestSenderMail.java的代码:

package test.mail;
import org.springframework.mail.MailException;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
public class TestSenderMail {
	private MailSender mailSender;
	private SimpleMailMessage mailMessage;
	public TestSenderMail() {
	}
	public SimpleMailMessage getMailMessage() {
		return mailMessage;
	}
	public void setMailMessage(SimpleMailMessage mailMessage) {
		this.mailMessage = mailMessage;
	}
	public MailSender getMailSender() {
		return mailSender;
	}
	public void setMailSender(MailSender mailSender) {
		this.mailSender = mailSender;
	}
	public void sendMail() {
		SimpleMailMessage message = new SimpleMailMessage(mailMessage); // 设置email内容,
		message.setText("测试Spring 发送Email.");
		try {
			mailSender.send(message);
		} catch (MailException e) {
			System.out.println("O . 发送Email失败了....");
			e.printStackTrace();
		}
	}
}

很简单吧. 下面是测试类: TestApp.java

package test.mail;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestApp { 
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("test/mail/mail.xml"); 
		TestSenderMail sender = (TestSenderMail) context.getBean("testMailSender");
		sender.sendMail();
	}
	//抛出如下异常,是瑞星监控的问题,关闭就可以了
	/**
	 * DEBUG SMTP: QUIT failed with 250 O . 发送Email失败了.... 
	 * org.springframework.mail.MailSendException: Could not send mails: 354
	 * com.sun.mail.smtp.SMTPSendFailedException: 354
	 * at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
	 * at com.sun.mail.smtp.SMTPTransport.finishData(SMTPTransport.java:1215) 
	 * at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:586)
	 */
}

呵呵, 现在就可以发送Email了.

最后提醒一下，记得要将：activation.jar 和 mail.jar 两个包导入到工程
