我想将 BootStrap.groovy 文件中的一些信息记录到控制台和日志文件中。输出报告了一些配置信息，并标记了应用程序从配置到执行阶段的过渡。我遇到的问题是仅在控制台上看到所需的输出，而不是在日志文件中。我的环境包括
- 圣杯 2.3.8
- 红帽企业 Linux 工作站 6.5 版
我提供了两个代码片段来展示我在做什么。它们也很容易插入一个空的 Grails 项目（不需要创建域类或控制器来查看我所看到的行为）。当我运行“ grails run-app ”时，我希望块的开发部分environments将 BootStrap 输出配置到两个位置。除了让日志记录到这两个位置之外，如果您对我的 log4j 配置有任何一般性建议，也将不胜感激。
我修改了我的BootStrap.groovy：
import grails.util.Environment
class BootStrap {
def grailsApplication
def init = { servletContext ->
log.info """
tryLoggingInGrails2-3-8 configuration {---------------- ${new Date()}
environment : ${Environment.current.name}
dataSource.username : ${grailsApplication.config?.dataSource?.username}
dataSource.url : ${grailsApplication.config?.dataSource?.url}
------------------------------------------------------}"""
}
def destroy = {
}
}
在Config.groovy中，log4j 配置部分是：
// ----------------------------- Start Config.groovy snippet
// log4j configuration
def catalinaBase = System.getProperty( 'catalina.base' )
if ( !catalinaBase ) catalinaBase = './target' // just in case
def logDirectory = "${catalinaBase}/logs"
def consoleLevelThreshold = org.apache.log4j.Level.WARN
def fileLevelThreshold = org.apache.log4j.Level.INFO
environments {
development {
consoleLevelThreshold = org.apache.log4j.Level.DEBUG
fileLevelThreshold = org.apache.log4j.Level.DEBUG
}
}
// Inside the log4j closure, use '${myAppName}' instead of '${appName}'
def myAppName = appName
log4j = {
appenders {
// This 'null' prevents the empty stacktrace.log file from being created
// in the default location, where we may not have permission to write
// in a production tomcat.
