Looking at grails-app/ conf/ Config. groovy, you see that the root logger is sending its output to the console, but the filter is set to error& rootLogger= "error, stdout". 查看grails-app/conf/Config.groovy,您会发现根登录程序将它的输出发送到控制台,但过滤器被设置为error&rootLogger=“error,stdout”。
Errors in processes beyond those in the Erlang shell are handled and recorded by the error logger, a built-in process that handles the error reporting. 除了Erlangshell中的错误以外,其他进程中的错误将由错误记录程序处理和记录,这是一个处理错误报告的内置进程。
