邮件异常日志记录在实时Grails webapp中

我希望我的Grails网络应用程序能够为每个到达最终用户的异常发送电子邮件.

基本上我正在寻找一种优雅的方式来实现相当于：

try {
      // ... all logic/db-access/etc required to render the page is executed here ...
  }
  catch (Exception e) {
      sendmail("exception@example.com", "An exception was thrown while processing a http-request", e.toString);
  }

原来这个确切的问题是几天前的 answered on the Grails mailing list.

解决方案是将以下内容添加到Config.groovy的log4j部分：

log4j {
    ...
    appender.mail='org.apache.log4j.net.SMTPAppender'
    appender.'mail.To'='email@example.com'
    appender.'mail.From'='email@example.com'
    appender.'mail.SMTPHost'='localhost'
    appender.'mail.BufferSize'=4096
    appender.'mail.Subject'='App Error'
    appender.'mail.layout'='org.apache.log4j.PatternLayout'
    appender.'mail.layout.ConversionPattern'='[%r] %c{2} %m%n'
    rootLogger="error,stdout,mail"
    ...
    // rootLogger="error,stdout" (old rootLogger)
}

另外将sun-javamail.jar和activation.jar添加到lib / -folder中.
