 Java代码：

HMAC-SHA-256工具类

import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.util.Formatter;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;

public class HmacSha256Util {

    private static final String HMAC_SHA1_ALGORITHM = "HmacSHA256";
    private static String toHexString(byte[] bytes) {
        Formatter formatter = new Formatter();
        for (byte b : bytes) {
            formatter.format("%02x", b);
        }
        return formatter.toString();
    }
 
    public static String signature(String data, String key) throws NoSuchAlgorithmException, InvalidKeyException {
        SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(), HMAC_SHA1_ALGORITHM);
        Mac mac = Mac.getInstance(HMAC_SHA1_ALGORITHM);
        mac.init(signingKey);
        return toHexString(mac.doFinal(data.getBytes()));
    }
 
    public static byte[] signatureReturnBytes(String data, String key) throws NoSuchAlgorithmException, InvalidKeyException {
        SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(), HMAC_SHA1_ALGORITHM);
        Mac mac = Mac.getInstance(HMAC_SHA1_ALGORITHM);
        mac.init(signingKey);
        return mac.doFinal(data.getBytes());
    }

}

SHA-256 工具方法：

public static String SHA256(String param) {
        if (StringUtils.isBlank(param)) {
            throw new IllegalArgumentException("param can not be null");
        }
        try {
            byte[] bytes = param.getBytes("utf-8");
            final MessageDigest md = MessageDigest.getInstance("SHA-256");
            md.reset();
            md.update(bytes);
            final Base64 base64 = new Base64();
            final byte[] enbytes = base64.encode(md.digest());
            return new String(enbytes);
        } catch (final NoSuchAlgorithmException e) {
            throw new IllegalArgumentException("unknown algorithm SHA-256");
        } catch (UnsupportedEncodingException e) {
            throw new RuntimeException(e);
        }
    }

测试：

public class Test01 {
    
    @Test
    public void getSHA256() throws UnsupportedEncodingException, InvalidKeyException, NoSuchAlgorithmException{
         StringBuilder stb = new StringBuilder();
         String content = stb.append("Date: ").append(getTime()).append("
").append("abc: ").append("123456").append("
").append("Digest: SHA-256=").append(getBody()).toString();
         System.out.println("签名前的数据："+content);
         String secret="kOI6ZHLGdgd2GB8osYZSl7QDCrHzAFg1";
         String signature2 = new String(Base64.getEncoder().encode(HmacSha256Util.signatureReturnBytes(content, secret)), "US-ASCII");    
        System.out.println("显示指定编码[推荐] signature:"+signature2);
       
    }
public String getTime() {
        Date d=new Date();
        DateFormat format=new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z", Locale.US);
        format.setTimeZone(TimeZone.getTimeZone("GMT"));
        String hdate = format.format(d);
        return hdate;
    }
    
    
    public String getBody() throws UnsupportedEncodingException {
        String body = "{"item":[{"address":"hpSg3NXvBAdaDcaeGQiPFF9tciW9BmcQv8Qm"}]}";        
        String sha2562 = Sha256Util.SHA256(body);
        return sha2562;
    }  
    
}
