Java 加密代码示例

1. HashExampleCode 类

package com.example.demo.util;
import java.util.List;
import java.util.Map;
import java.util.TreeMap;
import com.example.demo.util.MD5Util;
import org.springframework.util.StringUtils;


public class HashExampleCode {
    /**
     * sort the params.
     *
     * @param object
     * @return
     */

            }
        }

        }
        String params = sb.toString().replaceFirst("&", "");
        return MD5Util.MD5Encode(params + secretKey);
    }
}

2. MD5Util 类

package com.example.demo.util;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class MD5Util {
    /**
     * @param origin
     * @return string
     */
    private static final String[] hexDigits = {"0", "1", "2", "3", "4", "5",
            "6", "7", "8", "9", "a", "b", "c", "d", "e", "f"};

    }

        int n = b;
        if (n < 0) {
            n += 256;
        }
        int d1 = n / 16;
        int d2 = n % 16;
        return hexDigits[d1] + hexDigits[d2];
    }
}

3. JsonUtil 类

package com.example.demo.util;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.Map;
import com.fasterxml.jackson.databind.ObjectMapper;

class JsonUtil
{
    private static final ObjectMapper mapper = new ObjectMapper();

    static {
        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    }

    public static Map<String, Object> obj2Map(Object obj) {
        return mapper.convertValue(obj, Map.class);
    }

    public static String object2Json(Object o) {
        if (o == null) {
            return null;
        }

        String s = null;

        try {
            s = mapper.writeValueAsString(o);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return s;
    }
}

EG:

{
    "brandId": 100,
    "requestId": "039c630b-10be-43c2-bba1-70c8e0290997",
    "playerId": "2",
    "playerSessionId": "71f88d44-bc76-42f3-b748-45e2709070e0",
    "gameCode": "bfb",
    "trans": [
        {
            "seq": 1,
            "transId": "ptxia6xwasc75qksfswqkxd",
            "amount": 5,
            "transType": "bet",
            "transTime": "2023-08-24 07:21:20.434",
            "roundId": "789513231360",
            "roundType": "normal",
            "endRound": 0
        }
    ]
}

加密前的字符串是
brandId=100&gameCode=bfb&playerId=2&playerSessionId=71f88d44-bc76-42f3-b748-45e2709070e0&requestId=039c630b-10be-43c2-bba1-70c8e0290997&trans=[{"seq":1,"transId":"ptxia6xwasc75qksfswqkxd","amount":5,"transType":"bet","transTime":"2023-08-24 07:21:20.434","roundId":"789513231360","roundType":"normal","endRound":0}]mytestsecretkey
