File : MailMail.java

package com.yiibai.common;import org.springframework.mail.MailSender;import org.springframework.mail.SimpleMailMessage;public class MailMail{	private MailSender mailSender;	private SimpleMailMessage simpleMailMessage;		public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {		this.simpleMailMessage = simpleMailMessage;	}	public void setMailSender(MailSender mailSender) {		this.mailSender = mailSender;	}		public void sendMail(String dear, String content) {	   SimpleMailMessage message = new SimpleMailMessage(simpleMailMessage);			   message.setText(String.format(			simpleMailMessage.getText(), dear, content));	   mailSender.send(message);			}	}

2. Bean的配置文件

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/beanshttp://www.springframework.org/schema/beans/spring-beans-2.5.xsd"><bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">	<property name="host" value="http://www.mamicode.com/smtp.gmail.com" />	<property name="port" value="http://www.mamicode.com/587" />	<property name="username" value="http://www.mamicode.com/username" />	<property name="password" value="http://www.mamicode.com/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" />	<property name="simpleMailMessage" ref="customeMailMessage" /></bean>	<bean id="customeMailMessage"	class="org.springframework.mail.SimpleMailMessage">	<property name="from" value="http://www.mamicode.com/from@no-spam.com" />	<property name="to" value="http://www.mamicode.com/to@no-spam.com" />	<property name="subject" value="http://www.mamicode.com/Testing Subject" />	<property name="text">	   <value>		<![CDATA[			Dear %s,			Mail Content : %s		]]>	   </value>        </property></bean></beans>

4. 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("applicationContext.xml");    	     	MailMail mm = (MailMail) context.getBean("mailMail");        mm.sendMail("Yiibai", "This is text content");            }}

输出

Dear Yiibai, Mail Content : This is text content
