Foreword
2020 is a very special year, this year's Chinese New Year comes early than in previous years more, which means that this year's "gold and three silver four" probably will be in advance, which means that after the Spring Festival, it has to be recruitment into the season, the interview season. Time is of flies, and now manufacturers more competitive, more and more difficult to interview, so early preparation certainly not be wrong. What about the manufacturers, Java gang recruitment What are the requirements for the technical aspects of it? We are now ready, need to learn what technology stack or review it? Line architect review the route: On completion of this "technology stack" Spring trick confide manufacturers Offer.
Note: The following information contained in a private letter [spring] to receive a free trick ~
Architect tier companies essential technology stack
01 Spring architect essential family bucket series
(A) Spring Inside: Spring-depth analysis of the architecture and design principles
This document is divided into three parts, describes the Spring of core components and applications in three aspects. These three parts clear explanation about the architecture and design principles of Spring, Spring allows you to understand the depth of technology. All realized from the IOC, AOP to the database, transaction and so on. (Spring core implementation papers + Spring + Spring application components to achieve realization of articles published)
(B) in simple terms Spring Boot
Spring Boot Spring is not in place, but the Spring project can more quickly develop, deploy and test. It uses "convention over configuration" philosophy, providing a large number of starter in its interior, which in turn provides a number of automatic starter class configuration, allows developers to pursue the "ism" out of the box. While this can quickly develop, deploy and test, but will also have a big problem, that is, if you do not understand the principles of Spring, once the problem development occurs, developers can easily mess up, it is difficult to find the root of the problem , resulting in the developer's problems. So to learn Spring Boot must master the basics of Spring. Based on this situation, this book will discuss the application in conjunction with the principles of the Spring of Spring Boot.
(C) see through Spring MVC source code analysis and practice
- The first chapter website basics
- The second top Spring MVC
- Title III Spring MVC components analysis
- Part IV Summary and supplement
02 architects essential performance optimization series (MySQL + JVM + Tomcat)
(A) MySQL best learning route
(B) MySQL from entry to practice
MySQL book the best learning mode to distribute content structure, 1 to 4 allow the reader to grasp the basics of MySQL database, application skills, 5 to 6 allow the reader to have more industry experience in project development.
(C) JVM tuning notes summary
(D) in-depth analysis Tomcat
The book consists of 20 chapters, the first two chapters outline the contents of the book. Chapter 1 describes how the HTTP server is working, Chapter 2 presents a simple servlet container. Chapters 3 and 4, the description focuses on the connector, Chapter 5 - 20 describes the various components in the container.
03 architects must-distributed series (Redis + Nginx + Kafka)
(A) Redis Technical Notes
In simple terms redis is a traditional database, but the database is different from redis data is stored in memory so the write speed is very fast, and therefore is widely used in cache redis direction. In addition, it redis also often used for distributed lock. redis provides a variety of data types to support different business scenarios. In addition, redis supports transactions, persistence, LUA script, LRU-driven events, a variety of cluster solutions.
(Ii) proficient Nginx
(Iii) in-depth understanding of Kafka: the core design principles and practice
This document has 12 chapters and between chapters has a corresponding contact, essentially according to the elementary distributed hierarchical layer by layer to explain, if the reader has mastered some of its contents, you can choose to skip back and read content, but it is recommended that the reader read in accordance with the order.
Architects must-tier companies interviewed treasure book
Before the interview, brushing face questions is necessary, but the majority of Java programmers before the interview, are not systematically to brush the question, but think of what to see, so often there will be "mended watermelon, sesame lose "situation. In fact, this one by finishing first-tier manufacturers Architect interview Bao books, each interviewer, it is necessary to read in the interview Bao book, put together a lot of the core content, including Java virtual machine (JVM), Spring principle, Kafka, databases, algorithms, distributed, network, Netty and other major topics that lets you clearly understand that, as an architect, what core knowledge needed to master. The following content JVM as an example:
- Thread
- JVM memory area
- JVM runtime memory
- And garbage collection algorithm
- JAVA Fourth reference type
- GC generational collection algorithm VS partition collection algorithm
- GC garbage collector
- JAVA IO / NIO
- JVM class plus cutting mechanism
Conclusion
Finally, with regard to the interview, he made a personal three-point tips:
- Your efforts to improve their professional knowledge (technology)
- Position yourself to learn more about the requirements of (what control)
- Good image projects (external, internal), foster self-confidence, positive attitude
I wish, in spring you move smoothly, Offer hand!
Reminder: The above content involved face questions Ye Hao, study documents worth mentioning, can share out free, I hope we can work together to move the spring to take a good result! Require more than a friend to all the information, forwarding + comment on my article, I focus on, and then recruit private letter [spring] to receive a free ~
