Question

我的java邮件配置文件是

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"
        p:host="${mail.sender.host}" p:port="${mail.sender.port}" p:username="${mail.sender.username}"
        p:password="${mail.sender.password}" p:protocol="${mail.sender.protocol}"
        p:javaMailProperties-ref="mailProperties" />
    <bean id="emailClient"
        class="com.covisint.validationAdmin.validationAdminBackend.smtpMail.EmailClient"
        p:mailSender-ref="mailSender" p:emailSubject="${email.subject}" />
    <util:properties id="mailProperties">
        <prop key="mail.smtp.auth">${mail.smtp.auth}</prop>
        <prop key="mail.smtp.starttls.enable">${mail.smtp.starttls.enable}</prop>
        <prop key="mail.smtp.quitwait">${mail.smtp.quitwait}</prop>
        <prop key="mail.smtp.debug">${mail.smtp.debug}</prop>
        <prop key="mail.smtp.socketFactory.port">${mail.smtp.socketFactory.port}</prop>
        <prop key="mail.smtp.socketFactory.class">${mail.smtp.socketFactory.class}</prop>
        <prop key="mail.smtp.socketFactory.fallback">${mail.smtp.socketFactory.fallback}</prop>

    </util:properties>

我的属性文件是

email.subject = my email subject
mail.sender.host =smtp.gmail.com
mail.sender.port =465 //465 or 587 (both dint work)
mail.sender.username =****@gmail.com
mail.sender.password =******
mail.sender.protocol =smtp
mail.smtp.auth =true
mail.smtp.starttls.enable =true
mail.smtp.quitwait =false
mail.smtp.debug=true
mail.smtp.socketFactory.port=465
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.smtp.socketFactory.fallback=false

我收到了java邮件的错误
