java 遍历文件系统，栈溢出

[haxklryq]

java 遍历文件系统用递归，eclipse 直接卡住，代码如下，目录换成浅目录就可以

package tprem;

import java.util.ArrayList;
import java.util.List;
import java.util.Queue;
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
import java.util.concurrent.LinkedBlockingQueue;
import java.io.File;


public class LoadAllFile {	
	LinkedBlockingQueue<String> qudirs = new LinkedBlockingQueue<String>();
	LinkedBlockingQueue<String> qufile = new LinkedBlockingQueue<String>();
	public static ExecutorService cachedThreadPool = Executors.newCachedThreadPool();
	int hasrun = 0;
	int l = 0;
	
	public void loadFiles(final String oriPath) throws InterruptedException {		
		File file = new File(oriPath);
		File[] fileList = file.listFiles();
		
		for(int i = 0; fileList != null && i < fileList.length; i++) {
			if(fileList[i].isFile()) {
				qufile.put(fileList[i].getAbsolutePath());
			}
			else if(fileList[i].isDirectory()) {
				qudirs.put(fileList[i].getAbsolutePath());
			}
		}
		
		/*if(  qudirs.size()/100 - hasrun * 5 > 10&& hasrun < 10) {
		
			hasrun ++;
			cachedThreadPool.execute(new Runnable() {
				
				@Override
				public void run() {
					try {
						if(!qudirs.isEmpty()) 
							loadFiles(qudirs.take());
					} catch (InterruptedException e) {
						// TODO 自动生成的 catch 块
						e.printStackTrace();
					}					
				}
			});
		}*/
		
		if(l++ > 1000) {
			
			Thread t = Thread.currentThread();
		      String name = t.getName();
		      System.out.println("线程" + name + ":"+this. qudirs.size());
			l = 0;
		}
		
		if(!qudirs.isEmpty()) 
			loadFiles(qudirs.take());
		
		
	}
	
	public static void main(String [] args) {
		LoadAllFile l = new LoadAllFile();
		try {
			l.loadFiles("F:\\");
			int i = 0;
			i++;
			System.out.println(i);
			cachedThreadPool.shutdown();
			System.out.println(l.qufile.size());
		} catch (InterruptedException e) {
			// TODO 自动生成的 catch 块
			e.printStackTrace();
		}
	}
	
}

要怎么处理？网上没看到需要的信息

首先，有点疑问，你报的错对应java文件的行都是空行 其次，我运行了一下，并没有任何问题，只能说你的文件系统文件太多了 最后给点建议：你最后一步 if(!qudirs.isEmpty()) loadFiles(qudirs.take()); 可以把迭代放到 else if(fileList[i].isDirectory()) { qudirs.put(fileList[i].getAbsolutePath()); } 这里面，增加遍历速度
