logger的正确声明应该如下格式：

private static final transient
四个关键字应该全部加上。

commonloging版本：

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

private static final transient Log log = LogFactory.getLog(XXX.class);

log4j版本：

import org.apache.log4j.*;

private static final transient Logger log =
Logger.getLogger(XXX.class);

javautil logging版本:

import java.util.logging.*;

private static final transient Logger log =
Logger.getLogger(XXX.class.getName());
