本博客介绍log4j的日志管理配置

log4j.peroperties:

在D盘创建一个logs的文件夹来存放日志

### set log levels ### 
    log4j.rootLogger = info , Console , D
    #Console
    log4j.appender.Console=org.apache.log4j.ConsoleAppender
    log4j.appender.Console.layout=org.apache.log4j.PatternLayout
    log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
    log4j.logger.java.sql.ResultSet=INFO
    log4j.logger.org.apache=INFO
    log4j.logger.java.sql.Connection=INFO
    log4j.logger.java.sql.Statement=INFO
    log4j.logger.java.sql.PreparedStatement=INFO
    #output2file
    log4j.appender.D = org.apache.log4j.DailyRollingFileAppender 
    log4j.appender.D.File = D\:/logs/log.log 
    log4j.appender.D.Append = true 
    log4j.appender.D.Threshold = INFO \#\# \u8F93\u51FAinfo\u7EA7\u522B\u4EE5\u4E0A\u7684\u65E5\u5FD7 
    log4j.appender.D.layout = org.apache.log4j.PatternLayout 
    log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH\:mm\:ss} [ %t\:%r ] - [ %p ] %m%n

写个日志管理类：

package com.appweb.core.logger;
    
    
    public class Logger {
    
    	private org.apache.log4j.Logger logger;
    
    	
    	/**
    	 * 构造方法，初始化Log4j的日志对象
    	 */
    	private Logger(org.apache.log4j.Logger log4jLogger) {
    		logger = log4jLogger;
    	}
    
    	/**
    	 * 获取构造器，根据类初始化Logger对象
    	 * 
    	 * @param Class
    	 *            Class对象
    	 * @return Logger对象
    	 */
    	public static Logger getLogger(Class classObject) {
    		return new Logger(org.apache.log4j.Logger.getLogger(classObject));
    	}
    
    	/**
    	 * 获取构造器，根据类名初始化Logger对象
    	 * 
    	 * @param String
    	 *            类名字符串
    	 * @return Logger对象
    	 */
    	public static Logger getLogger(String loggerName) {
    		return new Logger(org.apache.log4j.Logger.getLogger(loggerName));
    	}
    
    	public void debug(Object object) {
    		logger.debug(object);
    	}
    
    	public void debug(Object object, Throwable e) {
    		logger.debug(object, e);
    	}
    
    	public void info(Object object) {
    		logger.info(object);
    	}
    
    	public void info(Object object, Throwable e) {
    		logger.info(object, e);
    	}
    
    	public void warn(Object object) {
    		logger.warn(object);
    	}
    
    	public void warn(Object object, Throwable e) {
    		logger.warn(object, e);
    	}
    
    	public void error(Object object) {
    		logger.error(object);
    	}
    
    	public void error(Object object, Throwable e) {
    		logger.error(object, e);
    	}
    
    	public void fatal(Object object) {
    		logger.fatal(object);
    	}
    
    	public String getName() {
    		return logger.getName();
    	}
    
    	public org.apache.log4j.Logger getLog4jLogger() {
    		return logger;
    	}
    
    	public boolean equals(Logger newLogger) {
    		return logger.equals(newLogger.getLog4jLogger());
    	}
    }

可以写个BaseController的控制类

然后将log的管理类加进来，实现日志管理的重复使用

package com.appweb.core.base;
    
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.springframework.web.context.request.RequestContextHolder;
    import org.springframework.web.context.request.ServletRequestAttributes;
    import org.springframework.web.servlet.ModelAndView;
    
    import com.appweb.core.entity.Page;
    import com.appweb.core.entity.PageData;
    import com.appweb.core.logger.Logger;
    import com.appweb.core.utils.UuidUtil;
    
    public class BaseController {
    	
    	protected Logger logger = Logger.getLogger(this.getClass());
    
    	private static final long serialVersionUID = 6357869213649815390L;
    	
    
    	
    	/**
    	 * 得到分页列表的信息 
    	 */
    	
    	
    	public static void logBefore(Logger logger, String interfaceName){
    		logger.info("");
    		logger.info("start");
    		logger.info(interfaceName);
    	}
    	
    	public static void logAfter(Logger logger){
    		logger.info("end");
    		logger.info("");
    	}
    	
    }

然后每个控制类都extends这个BaseController，使用日志的时候叫调用logger日志管理类
