spring简单电子邮件发送

先看配置，一些信息在mail.properties中定义：

<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
	    <list>
	      <value>classpath:init.properties</value>
	      <value>classpath:mail.properties</value>
	    </list>
    </property>
</bean>
.......
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
       <property name="host" value="${mail.host}"></property>
       <property name="username" value="${mail.username}"/>
       <property name="password" value="${mail.password}"/>
        <property name="defaultEncoding" value="UTF-8"></property>
        <property name="javaMailProperties">
             <props>
                 <prop key="mail.smtp.auth">${mail.smtp.auth}</prop>
                <prop key="mail.smtp.timeout">${mail.smtp.timeout}</prop>
            </props>
        </property>
</bean>
<bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage" singleton="false">
    <property name="from">
        <value>${mail.default.from}</value>
    </property>
</bean>

然后再java中这样也：

private JavaMailSender mailSender;//setter&getter
private SimpleMailMessage mailMessage;//setter&getter
........
if("sendMail".equals(action)){
 mailSender = this.getMailSender();
 mailMessage=this.getMailMessage();
 mailMessage.setTo("[e-mail]"); //接收人  
 mailMessage.setFrom(mailMessage.getFrom()); //发送人,从配置文件中取得
 mailMessage.setSubject("test mail测试邮件");
 mailMessage.setText("hello,this is my first mail!这是我第一封信！");
 mailSender.send(mailMessage);
}

我没有封装，应该很容易看懂。
明天准备发spring+velocity写成的模板邮件，今天来不及了，收工！下班！
