c#和java超强日志类LogTool

1、C# 日志类using System;using System.Collections.Generic; using System.Linq;using System.Text; using System.IO;using System.Threading;namespace LogTool/ / 日志类/ 当调用Write方法时不会造成线程阻塞,而是立即完成方法调用,因此调用线程不用等待日志写入文件之后才返回。/ public class Log : IDisposable/日志对象的缓存队列private static Queue msgs;/日志文件保存的路径private static

2、 string path;/日志写入线程的控制标记private static bool state;/日志记录的类型private static LogType type;/日志文件生命周期的时间标记private static DateTime TimeSign;/日志文件写入流对象private static StreamWriter writer;录日志/ /创建日志对象的新实例，采用默认当前程序位置作为日志路径和默认的每日日志文件类型记/ public Log(): this(., LogType.current)/ / 创建日志对象的新实例，采用默认当前程序位置作为日志路径并指定日

4、le (true)/判断队列中是否存在待写入的日志if (msgs.Count 0)Msg msg = null; lock (msgs)msg = msgs.Dequeue();if (msg != null)FileWrite(msg);else/判断是否已经发出终止日志并关闭的消息if (state)elseThread.Sleep(1);FileClose();/根据日志类型获取日志文件名，并同时创建文件到期的时间标记/通过判断文件的到期时间标记将决定是否创建新文件。private string GetFilename()DateTime now = DateTime.Now; str

9、l)writer.Flush(); writer.Close(); writer.Dispose(); writer = null;/ / 写入新日志，根据指定的日志对象Msg/ / 日志内容对象 public void Write(Msg msg)if (msg != null)lock (msgs)msgs.Enqueue(msg);/ / 写入新日志，根据指定的日志内容和信息类型，采用当前时间为日志时间写入新日志/ / 日志内容/ 信息类型 public void Write(string text, MsgType type)Write(new Msg(text, type);/ /

10、写入新日志，根据指定的日志时间、日志内容和信息类型写入新日志/ / 日志时间/ 日志内容/ 信息类型public void Write(DateTime dt, string text, MsgType type)Write(new Msg(dt, text, type);/ / 写入新日志，根据指定的异常类和信息类型写入新日志/ / 异常对象/ 信息类型 public void Write(Exception e, MsgType type)Write(new Msg(e.Message, type);#region IDisposable 成员/ / 销毁日志对象/ public void
