Java对接腾讯智慧校园开放平台，直接上代码。

关键代码如下：

public class Sign {

    private static final char[] HEXES = {
            '0', '1', '2', '3',
            '4', '5', '6', '7',

            'c', 'd', 'e', 'f'
    };

        if (bytes == null || bytes.length == 0) {
            return null;
        }

        StringBuilder hex = new StringBuilder();

        for (byte b : bytes) {
            hex.append(HEXES[(b >> 4) & 0x0F]);
            hex.append(HEXES[b & 0x0F]);
        }

        return hex.toString();
    }

            throws NoSuchAlgorithmException, InvalidKeyException, UnsupportedEncodingException {
        // 1. 拼接签名串
        // params 排序
        String[] keys = new String[param.size()];
        System.arraycopy(param.keySet().toArray(), 0, keys, 0, keys.length);

    }

    }
}

运行结果为：

报“应用未安装,请先安装应用,或联系管理员”的解决方法,请见https://blog.csdn.net/jlq_diligence/article/details/116355700

解决后的运行结果如下：
