写了一个依照WebLogic日志统计访问人数的Java类

写了一个按照WebLogic日志统计访问人数的Java类
自本人的小网站webdw.vicp.net上线以来,
每天都很想关心一下到底有多少人来看过,
但是看access.log太长了,不方便.
痛定思痛,终于下决心写了一个简单的日志统计类,
统计一下每天有多少IP,多少请求次数.
费话不说了,看代码.

import java.io.FileReader;
import java.io.BufferedReader;

public class WebLogicLogStat {
	class logline{
		String IP="";		//IP地址
		String date ="";	//访问日期
		int access =0;		//访问次数
	}
	public logline logall[] = new logline[10000];
	public int logid = 0;
	
	public String getLine(int id){
		return "<TR><TD>" +logall[id].IP + "</TD>"
		      +"<TD>" +logall[id].date +"</TD>"
		      +"<TD>" +logall[id].access +"</TD>"
		      +"</TR>";
		
	}
	public String readLogFile() throws Exception{

		filename = filepath + filename;
		System.out.println("Want access log file:" + filename);

附件两个压缩包,一个是java类,一个是调用java类的jsp文件
下面是界面的一个切图.


希望对大家有所帮助.
