在采用Java Mail发送邮件的时候，配置文件如下：


<!-- A test configuration -->
      <configuration>
        <!-- Change to your mail server prototocol -->
        <property name="mail.store.protocol" value="pop3"/>
        <property name="mail.transport.protocol" value="smtp"/>
		<property name="mail.smtp.auth" value="true"/>

        <!-- Change to the user who will receive mail  -->
        <property name="mail.user" value="xxxxxxxx@gmail.com"/>


        <!-- Change to the mail server  -->
        <property name="mail.pop3.host" value="pop.gmail.com"/>
		  <!-- The mail server port -->
        <property name="mail.pop3.port" value="995"/>

        <!-- Change to the SMTP gateway server -->
        <property name="mail.smtp.host" value="smtp.gmail.com"/>

        <!-- The mail server port -->
        <property name="mail.smtp.port" value="587"/>

        <!-- Change to the address mail will be from  -->
        <property name="mail.from" value="xxxxxxx@gmail.com"/>

        <!-- Enable debugging output from the javamail classes -->
        <property name="mail.debug" value="true"/>
      </configuration>

但莫名其妙的会出现下面的问题：


org.springframework.mail.MailSendException; nested exception details (1) are:

后来在晚上发现用gmail发信的时候，必须要设置下面的属性：


    <property name="mail.smtp.starttls.enable" value="true"/>

但不知道为什么，不知道谁给解答一下。
