Black Box: lupakan tentang logging

Halo!


Pada artikel sebelumnya, kami berbicara tentang logging dan pemrograman meta .


Sekarang mari kita bicara tentang meta logging.
Atau tentang penebangan semantik - sesuka Anda.


Logger "Bobbin" - ini adalah bunga. Dan ini buah beri: Kotak hitam .


pengantar


Saya mulai menggunakan Groovy pada tahun 2009.


Kemudian saya mulai meneliti bagaimana menyusun dan menstandardisasi logging dalam program.


Masalah


Ada kesenjangan metodologis dalam pendekatan dan praktik terbaik untuk mengintegrasikan logging ke dalam kode program.


Singkatnya, tidak ada seperangkat aturan yang diterima secara umum untuk membantu programmer memahami:


  • Data apa yang akan dicatat
  • Cara menyusun data yang dicatat
  • Kapan harus login
  • Di mana menempatkan kode logging di kode program
  • Bagaimana log yang dibuat akan digunakan
  • Mengapa menghabiskan waktu menulis kode logging?

Juga, tampaknya dengan adanya AST API (Groovy) dan CGLIB (Java) - alat otomatisasi logging seharusnya sudah muncul - tetapi tidak:


  • Groovy memiliki beberapa anotasi (@ Slf4j, Catatan, dll.) yang hanya mengimplementasikan deklarasi dan inisialisasi variabel logger.

Apakah senjata rahasia baru Groovy, serta dasar dari it.io ekosistem terbuka .


Menurut perkiraan kami, penggunaan menghemat hingga 25% sumber daya pada tahap penulisan kode program dan dari 20% hingga 500% dengan dukungan program.


Ini adalah implementasi unik dari konsep inovatif, didukung oleh pendekatan ilmiah untuk pengembangannya.
