未关闭InputStream 引起的血案
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"

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！！！
