使用jsp对文件进行操作
package test;
import java.io.*;
public class CatalogShow
{
private String fullPath;
public CatalogShow(){
fullPath="/";
}
public CatalogShow(String path)
{
fullPath=path;
}
public String decodeString(String src)
{
String des=null;
if(src!=null){
des="";
for(int i=0;i<src.length();i++)
{
if(src.charAt(i)==' '){
des+="%20";
}else{
des+=src.charAt(i);
}
}
}
return des;
}
public String addPath(String fileName)
{
String result="";
if(fullPath.charAt(fullPath.length()-1)=='\\')
{
result=fullPath+fileName;
}else{
result=fullPath+'\\'+fileName;
}
return decodeString(result);
}
public void setPath(String path)
{
fullPath=path;
}
public String dirUp(String path)
{
String result="";
File dir=new File(path);
result=dir.getParent();
return decodeString(result);
}
public File[] listFiles()
{
File dir=new File(fullPath);
String[] ss=dir.list();
if(ss==null)
return null;
int n=ss.length;
File[] fs=new File[n];
for(int i=0;i<n;i++)
{
fs<i>=new File(dir.getPath(),ss<i>);
}
return fs;
}
}
