下面的方法是从aws s3 读取文件对象下载到本地

public int downloadFile(HttpServletResponse httpResponse, String storePath, long p, long pend, int len, long realLen) throws IOException {	String key = getKeyByStorePath(storePath);	String bucketName = getBucketNameFromKey(key);		S3ObjectInputStream fis = null;	try {		fis = getObjectStream(bucketName, key);// 从aws s3 获取流				fis.skip(p);						// ... 对fis进行处理			} catch (Exception e) {		logger.error("aws下载失败  : " + mainHost);	}	return 0;}

　　从上面的代码看，并未关闭流。这个是代码上的低级错误。结果却花了比较长时间排除错误。。

未关闭InputStream ，一般编程可能也不会导致什么大的麻烦。比如我们看下面的代码：

private static void exec10000() {	JAVA_THREAD_NUM = 600;	HTTP_POOL_SIZE = 300;	DIR = "E:\\work\\testfiles\\10000+\\1000+ 38KB\\";	System.out.println("DISKFileTestUtil.exec10000()");	try {		File d = new File(DIR);		File[] listFiles = d.listFiles();		FILE_CNT = listFiles.length;		FileInputStream[] fiss = new FileInputStream[FILE_CNT];		for (int i = 0; i < listFiles.length; i++) {			File f = listFiles[i];			fiss[i] = new FileInputStream(f);			int c = 0;			while ((c = fiss[i].read()) != -1) {				System.out.print((char)c);			}			int available = fiss[i] .available();			System.out.println(available);		}	} catch (Exception e) {		e.printStackTrace();	}}假设E:\\work\\testfiles\\10000+\\1000+ 38KB 下有1000 个文件， 这样写，也没有关闭IO流，但是不会有什么大问题。

尽管如此，我观察到，这样还是会有问题的，至少存在性能问题： CPU 占用高，句柄数高

如下：

程序执行完毕，再观察，确实是大幅下降，句柄数下降了1000 多！！：

但是，这次真的引起了血案：

aws 的连接数是170，

下载文件超过一定数据（后面发现就是 170），连接不上了，然后引起aws 内部错误：

Caused by: org.apache.http.conn.ConnectionPoolTimeoutException: Timeout waiting for connection from pool

...

Timeout waiting for connection from pool 是什么鬼，连接超时？于是设置更长的超时时间，仍然没有解决问题，后面发现跟连接数N的设置有关，设置N个连接数，那么就只能下载N个文件。于是想，可能是连接池中的连接没关闭吧！

通过netstat -nat|grep -i "80" 观察下吧！

一开始，  很多连接还是处于 连接状态-bash-4.1# netstat -nat|grep -i "80"tcp        0      0 ::ffff:192.168.5.49:34994   ::ffff:192.168.5.81:80      ESTABLISHEDtcp        0      0 ::ffff:192.168.5.49:35012

170 --- 这个正是我设置的 maxconnection 的数值。

可见，

一开始，很多连接全部处于 ESTABLISHED，后面部分变成了 CLOSE_WAIT，后面则全部变成了CLOSE_WAIT —— 这就表示所有连接都超时了，都已经被动关闭，

———— 但是，很关键的是被动关闭的连接并不会释放，于是酿成了血案啊！

解决方法其实很简单，

try catch后面加个

finally {

if (fis != null) {

fis.close();

}

就好了！！！
