我正在使用具有以下配置的 Log4j 文件附加程序：
log4j.logger.com.atpl=INFO,ABW
log4j.appender.ABW=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ABW.File=c://atpl-platform-web//atplABW.txt
log4j.appender.ABW.DatePattern='.' yyyy-MM-dd
log4j.appender.ABW.layout=org.apache.log4j.PatternLayout
log4j.appender.ABW.layout.ConversionPattern= [%d] [%t] [%-5p] [%c] ==> %m%n
该文件正在给定位置创建。一旦我启动服务器，文件就会被锁定。但是当我尝试将数据记录到该文件中时，它不起作用。
private static final Logger FILE_LOGGER = Logger
.getLogger(TreeDemoAction.class);
FILE_LOGGER.info(gson.toJson(rootNode));
下面也是重新启动服务器登录。

谁能指导我这里有什么问题？我错过了什么吗？
谢谢。
