配置Grails以邮寄生产环境中生成的所有异常

Question

题:

• 如何配置Grails以发送包含生产环境中生成的所有log4j错误消息(包括例外)的电子邮件？

值得注意:

• 这个问题与Grails 1.1有关,这里描述了Grails 1.0的解决方案.

Answer 1

解决方案是将以下内容添加到Config.groovy的log4j部分:

log4j = {
  ...
  appenders {
    console name:'stdout', layout:pattern(conversionPattern: '[%r] %c{2} %m%n')
    if (grails.util.Environment.current == grails.util.Environment.PRODUCTION) {
      def patternLayout = new org.apache.log4j.PatternLayout()
      patternLayout.setConversionPattern("[%r] %c{2} %m%n")
      def mailAppender = new org.apache.log4j.net.SMTPAppender()
      mailAppender.setFrom("from@example.com")
      mailAppender.setTo("to@example.com")
      mailAppender.setSubject("An log4j error has been generated in the production environment")
      mailAppender.setSMTPHost("your-smtp-host")
      mailAppender.setLayout(patternLayout)
      appender name:'mail', mailAppender
    }
  }
  root {
    error 'stdout', 'mail'
    additivity = true
  }
  ...
}

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

此配置已经过测试,可以按预期工作.
