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
