跟着别人学ssm+springSecurity(二)

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.ConsoleAppender
log4j.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.PatternLayout
log4j.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 = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.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());
    }

}
