没有为logger找到appender（org.apache.http.client.protocol.RequestAddCookies）
我试图在Firefoxdriver上运行selenium webdriver代码，但在运行时我得到一个例外 –
log4j:WARN No appenders could be found for logger (org.apache.http.client.protocol.RequestAddCookies). log4j:WARN Please initialize the log4j system properly.

事实上，您获得的例外与您在post标题中提到的警告无关。
警告 ：它只告诉您没有为selenium驱动程序定义任何appender（有关更多信息，请参阅log4j文档 ）。 所以基本上，他不能记录你告诉它的地方（因为你没有告诉他在哪里）。
例外 ：您告诉（在您的测试用例中）selenium驱动程序与网页中的元素进行交互。 驱动程序没有找到这个元素，所以他无法与之交互。
如果你想谷歌你的例外更多的信息，请查找“元素当前不可见，因此可能无法与之交互”而不是log4j警告:)
添加依赖项（pom.xml）
log4j log4j 1.2.17
从log4j版本0.8.5开始，在类初始化时间类中，将从用于加载类的搜索路径中搜索文件log4j.properties
PropertyConfigurator.configure(System.getProperty("user.dir") + "/src/resources/log4j.properties");
创建log4j.properties文件
log4j.rootLogger=DEBUG, file log4j.appender.file=org.apache.log4j.RollingFileAppender log4j.appender.file.File=target/logs/httpClient.log log4j.appender.file.MaxFileSize=10MB log4j.appender.file.MaxBackupIndex=1 log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
这就够了。
对我来说，它应该在主类的开头添加以下行（ 开始后直接）
Properties log4jProp = new Properties(); log4jProp.setProperty("log4j.rootLogger", "WARN"); PropertyConfigurator.configure(log4jProp);
请在您的代码中包含此代码段…
System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.Jdk14Logger");
这可能会有所帮助
