Log4J使用

建立properties文件

建立Loggers类 统一管理

package com.trafree.banking.server.hardcore.util;

import org.apache.log4j.Logger;

public class Loggers {
public final static Logger businessLog = Logger.getLogger("businessLog");
public final static Logger exceptionLog = Logger.getLogger("exceptionLog");
public final static Logger bankingLog = Logger.getLogger("bankingLog");
public final static Logger puFaLog = Logger.getLogger("puFaLog");
public final static Logger zhongBangLog = Logger.getLogger("zhongBangLog");
}
