老生长谈，使用spring发送mail

<bean id="mailSenderImpl" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="${email.host}" />
<property name="protocol" value="smtp"/>
<property name="port" value="25"/>
<property name="defaultEncoding" value="UTF-8"/>
<property name="username" value="${email.username}" />
<property name="password" value="${email.password}" />
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
<!-- 使用gmail smtp server的必须参数 -->
<prop key="mail.smtp.starttls.enable">true</prop>
</props>
</property>
</bean>

email.host=smtp.126.com
email.servermail=kefu@126.com
email.tomail=zhongxf@126.com
email.username=kefu@126.com
email.password=aa87611606

@Autowired
private JavaMailSender mailSenderImpl;

MimeMessage mimeMessage = mailSenderImpl.createMimeMessage();

MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true, "UTF-8");

helper.setFrom("kefu@126.com");
helper.setTo("zhongxf@126.com");

mimeMessage.setSubject("kasdf好啊");
mimeMessage.setText("阿斯顿发斯蒂芬", "UTF-8");

//javaMailSenderImpl.send(mimeMessage);

mailSenderImpl.send(mimeMessage);
