Java 必须发出STARTTLS命令

java log4j

Java 必须发出STARTTLS命令,java,log4j,smtpappender,Java,Log4j,Smtpappender,我试图通过log4j发送错误电子邮件。通过使用以下附加器： <appender name="ERROR_MAIL" class="org.apache.log4j.net.SMTPAppender"> <param name="SMTPUsername" value="xxxxxx@gmail.com" /> <param name="SMTPPassword" value="**********" /> <param name=

我试图通过log4j发送错误电子邮件。通过使用以下附加器：

 <appender name="ERROR_MAIL" class="org.apache.log4j.net.SMTPAppender">
   <param name="SMTPUsername" value="xxxxxx@gmail.com" />
    <param name="SMTPPassword" value="**********" />
    <param name="To" value="test@gmail.com"/>
    <param name="From" value="xxxxxx@gmail.com"/>
    <param name="Subject" value="Newyse Error "/>
    <param name="SMTPHost" value="smtp.gmail.com"/>
    <param name="SMTPPort" value="25" />
    <param name="BufferSize" value="10"/>
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="[%d{ISO8601} %t %5p %c:$L]"/>
    </layout>
    <filter class="org.apache.log4j.varia.LevelRangeFilter">
      <param name="LevelMin" value="ERROR"/>
      <param name="LevelMax" value="FATAL"/>
    </filter>
  </appender>
从其他几个问题中，我了解到我需要在
smtpAppender

props.put("mail.smtp.starttls.enable", "true");
那么我们如何将它添加到现有的SMTPAppender中呢？

第一种方法：您可以扩展SMTP appender并重写createSession（）方法，在该方法中，您可以向Java邮件会话添加任何附加属性，如前面提到的“Mail.SMTP.starttls.enable”

第二种方式：您可以使用选项-Dmail.smtp.starttls.enable=true启动Java进程。这种方法看起来更简单，但需要控制JVM选项；它也可能会被过于检索的SecurityManager破坏。

非常感谢@Jk1给了我答案，让我获得了问题中提到的配置的工作代码

感谢您的帮助，是否无法从xml配置文件中设置此属性？SMTPAppender相当原始，不支持通过log4j.xml或log4j.properties进行tls相关配置。有人会花时间回答您，然后，您不仅会得到他的答案来解决问题，还会根据他的答案添加答案，然后接受你自己的答案？哥们，那是废话。。。我会被欺骗…@gaurav那么？我现在该怎么办？
