配置 log4j grails

Question

我是 grails 的新手，我需要为我的应用程序配置 loggind。我开始在我的 grails 应用程序中配置 log4j，但出现如下错误，我不知道是什么原因造成的：

log4j:ERROR Property missing when configuring log4j: Environment

有人知道是什么原因造成的吗？下面是我的代码！

def myappLogLevel = "DEBUG"
def myappLogPattern = "%d{yyyy-MM-dd/HH:mm:ss.SSS} [%t] %x %-5p %c{2} - 
%m%n"
def log4jFileName = System.properties.getProperty('catalina.base', '.') + 
"/logs/myapp.log"

environments {
    development {
       log4jFileName = "logs/myapp.log"
    }
test {
    log4jFileName = "logs/myapp.log"
}


log4j = {

def logLayoutPattern = new PatternLayout(myappLogPattern)

appenders {
    appender new DailyRollingFileAppender(name: "myappLog",
            threshold: Level.toLevel(myappLogLevel),
            file: log4jFileName,
            datePattern: "'.'yyyy-MM-dd",   //Rollover at midnight each day.
            layout: logLayoutPattern
    )
    if (Environment.current == Environment.DEVELOPMENT ||
            Environment.current == Environment.TEST) {
        appender new ConsoleAppender(name: "console",
                threshold: Level.toLevel(myappLogLevel),
                layout: logLayoutPattern
        )
    }
}

    if (Environment.current.name == "development" ||

    }
    root {
        error loggers as String[]
        additivity = true 
    }

}

Answer 1

您可以使用日志配置 DSL 构造在环境上分支，而无需显式访问环境。

environments {
    development { loggers.add('console') }
    test { loggers.add('console') }
}

也就是说，我不确定您要通过其余配置完成什么，因此可能有更优雅的处理方式。
