public class LimitedServletInputStream
extends javax.servlet.ServletInputStream

A LimitedServletInputStream wraps another ServletInputStream in order to keep track of how many bytes have been read and detect when the Content-Length limit has been reached. This is necessary since some servlet containers are slow to notice the end of stream and cause the client code to hang if it tries to read past it.

方法详细信息

readLine

public int readLine(byte[] b,
                    int off,
                    int len)
             throws IOException

Implement length limitation on top of the readLine method of the wrapped ServletInputStream.

覆盖：

类 javax.servlet.ServletInputStream 中的 readLine

参数：

b - an array of bytes into which data is read.

off - an integer specifying the character at which this method begins reading.

len - an integer specifying the maximum number of bytes to read.

返回：

an integer specifying the actual number of bytes read, or -1 if the end of the stream is reached.

抛出：

IOException - if an I/O error occurs.

read

public int read()
         throws IOException

Implement length limitation on top of the read method of the wrapped ServletInputStream.

指定者：

类 InputStream 中的 read

返回：

the next byte of data, or -1 if the end of the stream is reached.

抛出：

IOException - if an I/O error occurs.

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Implement length limitation on top of the read method of the wrapped ServletInputStream.

覆盖：

类 InputStream 中的 read

参数：

b - destination buffer.

off - offset at which to start storing bytes.

len - maximum number of bytes to read.

返回：

the number of bytes read, or -1 if the end of the stream has been reached.

抛出：

IOException - if an I/O error occurs.
