    Source Code Hunter

    Source Code Hunter

    Source code analysis of Spring, MyBatis, Redis, Netty, and more

    Source Code Hunter is an open source project by Doocs that focuses on analyzing and explaining the source code of widely used Java frameworks and libraries. It helps developers deepen their understanding of internal implementations, design patterns, and performance optimizations by walking through actual codebases such as Spring, MyBatis, Netty, Tomcat, and others. The project aims to bridge the gap between theoretical knowledge and real-world application by providing step-by-step annotated explorations of core components in these frameworks. It’s a valuable resource for Java developers preparing for interviews, system design discussions, or those looking to strengthen their ability to read and learn from production-level code.

    Large Text File converter

    Java Based Heavy-duty utilitity to process large delimited text files

    TextZilla is a Multithreaded Java utility which can process huge size delimited text files to extract, convert, encode, decode, encrypt/decrypt text data from source and write it in desired output file or files. It provides fully extensible framework based on which Java classes can be created, for example it currently has MD5 conversion capability, based on same design classes for 3DES ,AES or any other Algo can be created. Another strength of this tool is in its configurability, it's design allows to generate as many output files as required from one input file, and at every row of input file validation, extraction, conversion can be applied. Use case Example: legacy system is to be replaced with new advanced system with different DB schema, and the data provided as 100GB size of delimited text data which is to be inserted in 10 different tables of new system DB after validation,date format conversion, rearrangements, and MD5 hashing implementation.
