java spring 开启SMTP服务发送QQ邮件
首先进入自己的QQ邮箱，在设置中修改账户信息
然后来至底部
点击开启，再用手机发送对应信息到指定号码，然后点击我已发送
获取授权码
注意提示：
到这里，相信你已经开通了SMTP服务，这样就可以在java code发送邮件了
接下来的是Spring 中使用邮件服务
首先是配置信息使用的是587端口，刚开始用465端口我纠结了好久(使用465端口的错误详情)，用不了，你可以尝试，默认的25端口应该也是不适合的
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.qq.com"/>
<property name="port" value="587"/>//或许你可以用465端口，默认的25不适合
<property name="protocol" value="smtp"/>
<property name="username" value="[email protected]"/>
<property name="password" value="xxxxxxxxxxxx"/>//这里的是你通过短信后，获取的授权码
<property name="defaultEncoding" value="UTF-8"/>
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">trueprop>
<prop key="mail.smtp.timeout">25000prop>

<bean id="templateMessage" class="org.springframework.mail.SimpleMailMessage">

}温馨提示：
'cid:javaxmail.png'>
这是内嵌图片的方式 javaxmail.png 要和 messageHelper.addInline(file.getFilename(), file); 这里的 file.getFilename() 相一致就可以显示现在只差一步了，那就是Ctrl + F11，有不当之处敬请提出，共同进步
