今天看到一个方法，觉得写得不错，共享一下

Java code

/**     * Reads this input stream and returns contents as a byte[]     * from:aspectjweaver.jar     */    public static byte[] readAsByteArray(InputStream inStream) throws IOException {        int size = 1024;        byte[] buff = new byte[size];        int readSoFar = 0;        while (true) {            int nRead = inStream.read(buff, readSoFar, size - readSoFar);            if (nRead == -1) {                break;            }            readSoFar += nRead;            if (readSoFar == size) {                int newSize = size * 2;                byte[] newBuff = new byte[newSize];                System.arraycopy(buff, 0, newBuff, 0, size);                buff = newBuff;                size = newSize;            }        }        byte[] newBuff = new byte[readSoFar];        System.arraycopy(buff, 0, newBuff, 0, readSoFar);        return newBuff;    }

Java code

/**
* Reads this input stream and returns contents as a byte[]
* from:aspectjweaver.jar
*/
public static byte[] readAsByteArray(InputStream inStream) throws IOException ……

apache的IOUtil就有类似的函数。。。

解释一下，没看懂

难道没人见过 ByteArrayOutputStream 么？
[解决办法]

Java code

public static byte[] readStreamAsBytes(InputStream in) throws IOException {    if (in == null) {        return null;    }    ByteArrayOutputStream out = new ByteArrayOutputStream();    byte[] bys = new byte[4096];    for (int p = -1; (p = in.read(bys)) != -1; ) {        out.write(bys, 0, p);    }    return out.toByteArray();}
