你好 这个我写了个不知道 行不行 我把源码贴给你:
package test;
import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
public class IoTest {
public StringBuffer fileDoc(File path,StringBuffer sb){
//目录列表数组
File[] files = path.listFiles();
//字节流读取
FileInputStream fileInputStream = null;
for(File file1 : files){
if(file1.isDirectory()){//如果是目录
//递归
fileDoc(file1,sb);
}else{
try {
fileInputStream = new FileInputStream(file1);
int size = fileInputStream.available();
byte[] tempByte = new byte[size];
if(fileInputStream.read(tempByte) != size){
System.out.println("文件读取失败!!!");
}else{
//内容转换
String change = new String(tempByte,"utf-8");
sb.append(change);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
return sb;
}
//保存数据
public static void saveDataForTxt(StringBuffer sbStr){
//总数据
String allStr = sbStr.toString();
byte[] bytes = allStr.getBytes();
//将数据放到字节输入流中
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
//1k的数据
byte[] newbytes = new byte[1024];
int len = 0;
int i = 1;
try {
while((len = bais.read(newbytes)) != -1){
File file = new File("d:\\java\\"+i+".txt");
new FileOutputStream(file).write(newbytes,0,len);
i++;
}
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
String path = "d:\\TDDownload\\Test1";
File file = new File(path);
//要得到的数据集合(初始)
StringBuffer sbTemp = new StringBuffer();
sbTemp = new IoTest().fileDoc(file,sbTemp);
saveDataForTxt(sbTemp);
}
