Java 记录日志

日志程序

直接调用logWriter方法即可。参考链接：http://blog.csdn.net/luoweifu/article/details/46495045

package com.newtd.log;

import java.io.IOException;
import java.io.InputStream;
import java.util.logging.LogManager;
import java.util.logging.Logger;

    static LogManager logManager = LogManager.getLogManager();

配置文件

# "handlers" specifies a comma separated list of log Handler
#handlers= java.util.logging.ConsoleHandler
handlers= java.util.logging.FileHandler

# Default logging level.
.level= CONFIG

# default file output is in "E:\Test" directory.
java.util.logging.FileHandler.pattern = ./odps_to_jedis.log
java.util.logging.FileHandler.limit = 50000
java.util.logging.FileHandler.count = 1
java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter

# Limit the message that are printed on the console to CONFIG and above.
java.util.logging.ConsoleHandler.level = CONFIG
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter


# Facility specific properties.Provides extra control for each logger.
# For example, set the com.xyz.foo logger to only log SEVERE messages:
com.xyz.foo.level = SEVERE
