Question

我正在尝试提供自定义日志文件的相对路径。但它不起作用，如果我从完整的路径给出它工作正常。

我的代码是这样的：

log4j = {
    appenders {
        //  append new appenders of your own and add log level and packages/files like to add.
        rollingFile name: "myAppender",
                    maxFileSize: 1024,
                    file: "C:/GrailsWS/BaseGrails/target/basegrails.log"    // WORKING
                                          //"basegrails.log"   // NOT WORKING
                                          //"/target/basegrails.log"   //  NOT WORKING

        /*console name: "myAppender",
                layout: pattern(conversionPattern: "%c{2} %m%n")*/
    }
    debug myAppender: 'com.nagarro.base.grails.EmployeeController'
}

我尝试了以上方法，但它无效。

在tomcat / jetty的日志目录中写入日志，或者如果使用run-app启动，则在项目根目录中写入日志我使用它（如果有帮助）：

String logName = “myapp.log"
String logDirectory
// getting tomcat dir
logDirectory = System.getProperty('catalina.base') ? "${System.getProperty('catalina.base')}/logs/" : ''
// getting jetty dir
if (System.getProperty('jetty.home') != null) {
    logDirectory = System.getProperty('jetty.home') ? "${System.getProperty('jetty.home')}/logs/" : ''
}

println("CONFIG:Writing log ${logName} in dir:" + logDirectory)

// log4j configuration
log4j = {

    appenders {
        appender new DailyRollingFileAppender(
                name: 'file', datePattern: "'.'yyyy-MM-dd",
                file: logDirectory + logName
        )}
...

相对路径不适用于Grails中的日志文件
