加入日志组件

一、Log4j配置文件：目录：Resource，文件名：log4j.properties

#定义LOG输出级别log4j.rootLogger=INFO,Console,File#定义日志输出目的地为控制台log4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.Target=System.out#可以灵活地指定日志输出格式，下面一行是指定具体的格式log4j.appender.Console.layout = org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=[%c] - %m%n#文件大小到达指定尺寸的时候产生一个新的文件log4j.appender.File = org.apache.log4j.RollingFileAppender#指定输出目录log4j.appender.File.File = logs/ssm.log#定义文件最大大小log4j.appender.File.MaxFileSize = 10MB# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志log4j.appender.File.Threshold = ALLlog4j.appender.File.layout = org.apache.log4j.PatternLayoutlog4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

二、Log4j的再封装工具：目录：com.zyj.util，文件名：Log.java

package com.zyj.util;import org.apache.commons.logging.LogFactory;public class Log {    public static void info(Object object, String tittle, String text) {        org.apache.commons.logging.Log logger = LogFactory.getLog(object.getClass());        String infoStart = "\n————————————————————————————————————————————————————————[Info Start]——\n";        String infoEnd = "————————————————————————————————————————————————————————[Info   End]——\n";        StringBuffer stringBuffer = new StringBuffer(infoStart);        stringBuffer.append("标题:" + tittle + "\n内容:")                .append(text + "\n")                .append(infoEnd);        logger.info(stringBuffer.toString());    }    public static void error(Object object, String tittle, String text, Throwable t) {        org.apache.commons.logging.Log logger = LogFactory.getLog(object.getClass());        String infoStart = "\n————————————————————————————————————————————————————————[Info Start]——\n";        String infoEnd = "————————————————————————————————————————————————————————[Info   End]——\n";        StringBuffer stringBuffer = new StringBuffer(infoStart);        stringBuffer.append("标题:" + tittle + "\n内容:")                .append(text + "\n")                .append(infoEnd);        logger.error(stringBuffer.toString(), t);    }    public static void debug(Object object, String tittle, String text) {        org.apache.commons.logging.Log logger = LogFactory.getLog(object.getClass());        String infoStart = "\n————————————————————————————————————————————————————————[Info Start]——\n";        String infoEnd = "————————————————————————————————————————————————————————[Info   End]——\n";        StringBuffer stringBuffer = new StringBuffer(infoStart);        stringBuffer.append("标题:" + tittle + "\n内容:")                .append(text + "\n")                .append(infoEnd);        logger.debug(stringBuffer.toString());    }}
