spring框架之邮件发送

Spring发送邮件的相关配置及程序：引入相应的jar包，同时可能会出现一个错误--

java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream

这是由于JAVAEE5中的javaee.jar中的mail和mail.jar冲突导致的,解决的方法是将Library改成J2EE 1.4 Libraries就行了.

<!-- 发送email的配置. -->
<bean id="mailSender"
	class="org.springframework.mail.javamail.JavaMailSenderImpl">
	<property name="host" value="smtp.163.com"></property>
	<property name="javaMailProperties">
		<props>
			<prop key="mail.smtp.auth">true</prop>
			<prop key="mail.smtp.timeout">25000</prop>
			<prop key="mail.transport.protocol">smtp</prop>
			<prop key="mail.smtp.auth">true</prop>
			<prop key="mail.smtp.starttls.enable">true</prop>
		</props>
	</property>
	<property name="username" value="*********@163.com" />
	<property name="password" value="*********" />
</bean>

其中username和password指的是发送端的邮箱用户名和密码。
