/**
 * 基于Log4j的BizLogger
 * @author duanyy
 * @version 1.2.7 [20140828 duanyy] 

 * - 重写BizLogger
 * 
 * @version 1.2.7.1 [20140902 duanyy] 

 * - 增加app信息的输出
 * 
 * @version 1.2.8 [20140917 duanyy] 

 * - Handler:handle和flush方法增加timestamp参数，以便时间同步 

 * 
 * @version 1.6.4.11 [20151116 duanyy] 

 * - 日志类型为none的服务日志也将输出到bizlog，在此过滤掉为none的输出
