Alibaba Java Development Manual

The "Alibaba Java Development Manual (Official Version)" launched by Alibaba Group is the crystallization of the collective wisdom of nearly 10,000 Alibaba development students. It focuses on the development perspective and lists in detail how to develop more efficiently, more fault-tolerant, and more collaborative. Strive to know what is true and what is not true, and combine positive and negative examples to enable Java developers to improve collaboration efficiency and code quality.

The vision of "Alibaba Java Development Manual" is to code with high efficiency and code with quality. It combines the author's development experience and architecture history, refines the collective programming experience and software design wisdom of the Alibaba Group's technical team, and condenses it into three-dimensional programming specifications and best practices. As we all know, the rapid development of the modern software industry requires higher and higher comprehensive quality of developers, because not only knowledge points related to programming, but also knowledge points in other dimensions will affect the final delivery quality of the software.

For example, defects in the table structure and index design of the database may bring architectural defects or performance risks to the software; misplacement of unit testing makes integration testing difficult; vulnerable code without authentication is easily attacked by hackers, etc.

Therefore, this manual takes the developer as the center perspective and is divided into seven dimensions: programming specifications, exception logs, unit tests, security specifications, MySQL database, engineering structure, and design specifications. There are corresponding items under each item. Expanded explanations and explanations, positive examples and counter-examples, comprehensively, three-dimensionally and vividly help the growth of developers and the formation of team code specification culture.

Strictly speaking, the "Alibaba Java Development Manual" goes beyond the Java language itself and clarifies the basic qualities that a qualified developer should have. Therefore, this manual is suitable for managers and R&D in computer-related industries. It is intended to be read by personnel, computer majoring teachers and students in colleges and universities, job seekers, etc. It is hoped that it will become a work manual, tool dictionary and bedside book for everyone like a mentor and helpful friend.
