java - Log4j SMTPappender 错误

Question

我正在尝试使用下面的 log4j SMTPappender。错误。所有其他附加程序都工作正常。

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

<!--                          -->
<!-- Declare the SMTPAppender -->
<!--                          -->
<appender name="EMAIL"  class="org.apache.log4j.net.SMTPAppender">
    <param name="BufferSize" value="512" />
    <param name="SMTPHost" value="relaymail.xxx.com" />
    <param name="From" value="xxx@xxx.com" />
    <param name="To" value="xxx@xxx.com" />
    <param name="Subject" value="[SMTPAppender] Application message" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern"
          value="[%d{ISO8601}]%n%n%-5p%n%n%c%n%n%m%n%n" />
    </layout>
    <filter class="org.apache.log4j.varia.LevelRangeFilter">
        <param name="LevelMin" value="ERROR"/>
        <param name="LevelMax" value="FATAL"/>
    </filter>
</appender>

<!--                           -->
<!-- setup log4j's root logger -->
<!--                           -->
<root>
    <level value="all" />
    <appender-ref ref="EMAIL" />
</root>

我的Java代码

import org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;
public class simpandfile{
   static Logger logger = Logger.getLogger(simpandfile.class);
   public static void main(String args[]) {
      DOMConfigurator.configure("xmllog4jconfig.xml");
      System.setProperty("mail.smtps.host", "smtp.gmail.com:465");
      System.setProperty("mail.smtps.auth", "true");
      logger.debug("Here is DEBUG");
      logger.info("Here is some INFO blah");
      logger.warn("Here is some WARN");
      logger.error("Here");
      logger.debug("prasanna Test");
   }
}
