如何解决此错误消息＆＃34; log4j：配置log4j时缺少ERROR属性：grails＆＃34;

Question

我一直在使用grails一段时间，感觉可以处理这个错误。

每次我尝试使用“run-app”命令，当我将日志文件视为部署时，我会在输出中看到这一行

log4j:ERROR Property missing when configuring log4j: grails

我无法想象它的寻找方式。我正在部署几个环境，每个环境都显示相同的消息。

这是我在config.groovy中的阻止：

def appName = "${appName}"
def catalinaBase = System.properties.getProperty('catalina.base')
if (!catalinaBase) catalinaBase = '.'   // just in case
def logDirectory = "${catalinaBase}/logs"

log4j = { root ->
appenders {
    rollingFile name:'stdout', file:"${logDirectory}/${appName}.log".toString(), maxFileSize:'10MB'
    rollingFile name:'stacktrace', file:"${logDirectory}/${appName}_stack.log".toString(), maxFileSize:'1MB'
}

}

我在这里想到的log4j正在寻找什么？

保持配置如下。通过删除不需要的和不相关的配置，在log4j中添加envirnoment level log4j config。

def appName = "${appName}"
def catalinaBase = System.properties.getProperty('catalina.base')
if (!catalinaBase) catalinaBase = '.'   // just in case
def logDirectory = "${catalinaBase}/logs"

grails.plugin.databasemigration.updateOnStart = true

log4j = { root ->
    appenders {
        rollingFile name: 'stdout', file: "${logDirectory}/${appName}.log".toString(), maxFileSize: '10MB'
        rollingFile name: 'stacktrace', file: "${logDirectory}/${appName}_stack.log".toString(), maxFileSize: '1MB'
    }
