Как настроить приложение SMTP для резервного копирования на groovy?

Question

Я пытаюсь настроить Logback SMTP appender с помощью Groovy для моего автономного приложения Java. Мое содержание logback.groovy файл ниже:

import ch.qos.logback.classic.PatternLayout 
    import ch.qos.logback.classic.encoder.PatternLayoutEncoder 
    import ch.qos.logback.classic.net.SMTPAppender 
    import ch.qos.logback.core.ConsoleAppender 

    import static ch.qos.logback.classic.Level.INFO 

    def common_log_date_format = "{MM/dd HH:mm:ss:SSS}" 
    def common_log_conversionpattern = "[%d${common_log_date_format}] [%t] [%c{0}] [%p]: %m%n" 

    appender("STDOUT", ConsoleAppender) { 
     encoder(PatternLayoutEncoder) { 
     pattern = "${common_log_conversionpattern}" 
     } 
    } 

    appender("EMAIL", SMTPAppender) { 
     smtpHost = "xxxx" 
     to = "yyyy" 
     from = "zzzz" 
     subject = "[${app.name}] [%marker] [%p]" 
     asynchronousSending = false 
     layout(PatternLayout) { 
     pattern = "${common_log_conversionpattern}" 
     } 
    } 

    root(INFO, ["STDOUT", "EMAIL"]) 

Но эта конфигурация не работает, он не во время запуска приложения с:

Я не могу понять причину этого сообщения. Если я удаляю конфигурационную часть SMTP Appender из config - работы приложений и журналы в порядке. Как заставить SMTP appende работать с groovy конфигурацией?

Мое окружение: Ubuntu 12.04, logback classic/core 1.0.13, Groovy-all jar version 2.2.0-rc-3, Janino 2.6.1, javax.mail 1.4.

Answer 1

Хорошо, я нашел свою ошибку. app.name было свойством из включенной конфигурации, которая не указала после обновления config до groovy. Вопрос решен.

Answer 2

Это мое решение для заводной & Граалей 3.2.0 Appender с Smtp Gmail, для тестирования и производственной среды:

import grails.util.BuildSettings 
import grails.util.Environment 
import ch.qos.logback.classic.html.HTMLLayout 
import ch.qos.logback.classic.encoder.PatternLayoutEncoder 
import ch.qos.logback.classic.net.SMTPAppender 
import ch.qos.logback.core.ConsoleAppender 

// See http://logback.qos.ch/manual/groovy.html for details on configuration 
appender('STDOUT', ConsoleAppender) { 
    encoder(PatternLayoutEncoder) { 
     pattern = "%level %logger - %msg%n" 
    } 
} 

appender("EMAIL", SMTPAppender) { 
    smtpHost = "smtp.gmail.com" 
    smtpPort = 587 
    STARTTLS = true 
    username = "email@gmail.com" 
    password = "password" 
    to = "emailRecepter@domain.com" 
    from = "email@gmail.com" 
    subject = "Logback Sam error" 
    asynchronousSending = false 
    layout(HTMLLayout) { 
     pattern = "%level %logger - %msg%n" 
    } 
    println "Setting EMAIL property" 
} 

def targetDir = BuildSettings.TARGET_DIR 
if (Environment.isDevelopmentMode() && targetDir != null) { 
    appender("FULL_STACKTRACE", FileAppender) { 
     file = "${targetDir}/stacktrace.log" 
     append = true 
     encoder(PatternLayoutEncoder) { 
      pattern = "%level %logger - %msg%n" 
     } 
    } 
    logger("StackTrace", ERROR, ['FULL_STACKTRACE'], false) 
    root(ERROR, ['STDOUT', 'FULL_STACKTRACE']) 

} 
else { 
    root(ERROR, ['STDOUT','EMAIL']) 
}
