?xml version1.0 encodingUTF-8?

/Configuration然后实现日志工具类
package LIS.Core.Util;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;public class LogUtils {//得到日志操作,默认写在Tomcat的Bin下//异常日志static final Logger loggerException LogManager.getLogger(Exception);//操作日志static final Logger loggerOperation LogManager.getLogger(Operation);//调试日志static final Logger loggerDebug LogManager.getLogger(Debug);//sql日志static final Logger loggerSqlLog LogManager.getLogger(SqlLog);//性能日志static final Logger loggerCapability LogManager.getLogger(Capability);//安全日志static final Logger loggerSecurity LogManager.getLogger(Security);/// summary/// 书写调试日志/// /summary/// param namemessage日志内容/parampublic static void WriteDebugLog(String message){loggerDebug.debug(message);}/// summary/// 书写异常日志/// /summary/// /// param namemessage日志内容/param/// param nameexception异常对象/parampublic static void WriteExceptionLog(String message, Exception exception){loggerException.error(message, exception);}/// summary/// 书写性能日志/// /summary/// param namemessage日志内容/parampublic static void WriteCapabilityLog(String message){loggerCapability.info(message);}/// summary/// 书写安全日志/// /summary/// param namemessage日志内容/parampublic static void WriteSecurityLog(String message){loggerSecurity.info(message);}/// summary/// 书写操作日志/// /summary/// param namemessage日志内容/parampublic static void WriteOperationLog(String message){loggerOperation.info(message);}/// summary/// 书写调试日志/// /summary/// param namemessage日志内容/parampublic static void WriteSqlLog(String message){loggerSqlLog.debug(message);}
}
调用写日志测试 在Tomcat的Bin下的Logs生成日志 后面就把System.out.println的打印日志换为LIS.Core.Util.LogUtils写日志了
