grails - 我的log4j配置不会产生任何输出

Question

我试图在我的webapp中使用log4j，我根据this博客中的例子写了一个log4j配置。

创建了文件，但没有输出。我尝试了不同的配置但没有成功

Config.groovy中

<?php
if ($_POST['textEmail'] != '') {
    $text = str_replace(" ", '&nbsp;', $_POST['textEmail']);
    $pattern = '/([a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,6})/';
    preg_match_all($pattern,file_get_contents("update.txt"), $matches);
    $emails = $matches[0];   // get Array of all email in file 
    if (!in_array($text, $emails)) {     // echck for existing email 
        file_put_contents("update.txt", PHP_EOL.$_POST['textEmail'], FILE_APPEND);
    }else{
        echo 'Email address alerady exist';
    }
   echo  $f = file_get_contents("update.txt");
}
?>
