调用方法：

public class MyLogs {
/**

* @param warningMsg警告信息
* @param className 类名
* @param methodName方法名
*/
public void recordWarningLogs(String warningMsg,String modelName,String className,String methodName){
PropertyConfigurator.configure("res/txt/log4j.properties");
Logger logger = Logger.getLogger(modelName.trim()+"_WARN");
logger.warn(warningMsg+"类名:"+className+" 方法名:"+methodName);
}
/**

* @param errorMsg 错误信息
* @param className 类名
* @param methodName 方法名
*/
public void recordErrorLogs(String errorMsg,String modelName,String className,String methodName){

Logger logger = Logger.getLogger(modelName.trim()+"_ERROR");
logger.error(errorMsg+"类名:"+className+" 方法名:"+methodName);
}
}
