java泛型静态方法实际使用

静态泛型方法定义：

public static <T> T deserialize(byte[] byteArray) {
		ObjectInputStream oip = null;
		try {
			oip = new ObjectInputStream(new ByteArrayInputStream(byteArray));
			@SuppressWarnings("unchecked")
			T result = (T) oip.readObject();
			return result;
		}
		catch (IOException e) {
			throw new IllegalArgumentException(e);
		}
		catch (ClassNotFoundException e) {
			throw new IllegalArgumentException(e);
		}
		finally {
			if (oip != null) {
				try {
					oip.close();
				}
				catch (IOException e) {
					// eat it
				}
			}
		}
	}

泛型方法使用：

private OAuthzCodeRequestHolder deserializeAuthorization(byte[] authorization){
		return SerializationUtils.deserialize(authorization);
	}
