MyBatisCodeHelperPro Crack

准备工作

• Jar反编译 Jadx Cfr
• MyBatisCodeHelperPro 插件包

开始处理

1. 反编译

1. 反编译Jar包
2. 使用IDEA编辑器打开编译包
3. 全局检索关键词 TUlHZk1BMEdDU3FHU0liM0RRRUJBUVVBQTRHTkFEQ0JpUUtCZ1FDZzUyUjExV0h1MysvNUV2WnhkS0l2a3ovekpnS2VNUUhNLytMVkxSZS9zWUpFQlUxbUUrODc3MmJJckk4UThscldqSHc5cmVjQ1RWVVhXUnhWYXBndk1HYTZ3KzU4STZwYXdSaFhwZDBrRkhUY2xxeUZGWFpoS3ZiQUtoblphRGNuZkJtSkhObTQwR0JFTGpCTmx5MXpha2FIblFmUzF0QlhaSGQwOUV0c2VRSURBUUFC
4. 正式版类名以及方法名称都会被混淆，反编译后细心查找，示例如下:

package com.ccnode.codegenerator.validate.utils;

import com.ccnode.codegenerator.validate.response.ValidateNewResultData;
import com.google.gson.Gson;
import java.io.UnsupportedEncodingException;
import java.security.interfaces.RSAPublicKey;
import java.util.Base64;
import kotlin.text.Charsets;

public class RsaUtils {
    private static Gson gson = new Gson();

    public static ValidateNewResultData fromEncrptData(String encrptString) {
        Object var1 = null;

        byte[] res;
        try {
            res = RSAEncrypt.decrypt(RSAEncrypt.loadPublicKeyByStr(new String(Base64.getDecoder().decode("TUlHZk1BMEdDU3FHU0liM0RRRUJBUVVBQTRHTkFEQ0JpUUtCZ1FDZzUyUjExV0h1MysvNUV2WnhkS0l2a3ovekpnS2VNUUhNLytMVkxSZS9zWUpFQlUxbUUrODc3MmJJckk4UThscldqSHc5cmVjQ1RWVVhXUnhWYXBndk1HYTZ3KzU4STZwYXdSaFhwZDBrRkhUY2xxeUZGWFpoS3ZiQUtoblphRGNuZkJtSkhObTQwR0JFTGpCTmx5MXpha2FIblFmUzF0QlhaSGQwOUV0c2VRSURBUUFC"), Charsets.UTF_8)), Base64.getDecoder().decode(encrptString));
        } catch (MyException var7) {
            res = RSAEncrypt.decrypt((RSAPublicKey)(new MyPublicKey()), Base64.getDecoder().decode(encrptString));
        }

        ValidateNewResultData data = null;

        String json;
        try {
            json = new String(res, "UTF-8");
        } catch (UnsupportedEncodingException var6) {
            throw new RuntimeException(var6);
        }

        try {
            data = (ValidateNewResultData)gson.fromJson(json, ValidateNewResultData.class);
            return data;
        } catch (Exception var5) {
            throw new RuntimeException("gson catch exception, the json string is" + json, var5);
        }
    }
}

2. 添加依赖

<!-- https://mvnrepository.com/artifact/org.javassist/javassist -->
<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.30.2-GA</version>
</dependency>

注: 反编译后找到实际的全限定类名，以及方法名称后替换。

import javassist.*;
import org.springframework.lang.NonNull;

import java.io.*;
import java.nio.file.*;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.stream.Stream;

}

3. 打包安装

1. 将最终修改后的目录压缩为ZIP插件包
2. 将修改后的插件包安装到IDEA编辑器

4. 离线激活
