Foreword
According to the latest official statement Spring, Spring is the origin of modern Java.
Admittedly, Spring both in the Java ecosystem, or in the job market, is the absolute king. Interview appearance rate high, the production of wide scale, second to none. As technology advances, Spring IoC framework from the past, has developed into Cloud Native infrastructure, derived from a large number of Spring technology stack, such as the well-known Spring Boot, Spring Cloud Spring Security and so on. Therefore, Spring ecosystem are becoming huge, such as Apache Dubbo integration of the Spring Framework, various types of middleware Spring Boot Starter, and a variety of Spring Cloud implementations.

Developers face of sudden changes, both in architecture selection, or in the daily development, will always face a variety of challenges and tests. Only systematic grasp Spring Framework programming ideas, design concepts, and specific implementation before its capability in order to avoid a dilemma.
Ecological technology as the cornerstone of Spring, Spring Framework in terms of design, or in the implementation, is a good framework, many of the details are very worthy of our study, include:
Use Java language features, such as reflections, dynamic agency, enumeration, generics, annotations, ARM, Lambda grammar, etc.
Realization of design ideas and models, such as OOP, IoC, DDD, TDD, GoF23 etc.
Package and simplify the Java API, such as JDBC, Transaction, Servlet, JPA, JMS, Bean Validation etc.
JSR (Java Specification Requests) adaptation and implementation of norms
Integration and ease of use of third-party frameworks, such as MyBatis, Hibernate, Redis, etc.
Of course, as a member of the community-oriented programming RMB, we should not only focus on technical development, but also pay attention to the benefits of economic plane. A deep understanding of Spring Framework, no doubt you enter the giant, better career development must be crossed a storm .
Personally think, Spring in the " strategy is the excessively overvalued," " tactics undervalued on."
Here the " strategy " refers to the design and protocol specifications, such as OOP, IoC, AOP, design patterns and all kinds of standards such as JSR these aspects, Spring no apparent breakthrough, basically in compliance with the industry standard in execution.
In the " tactical " level, Spring has huge advantages, including hard to verify the stability of the API abstract force, modular design, functionality, scalability, and testability.
Because a lot of guys do not understand, " strategy " is not very familiar with the " tactics " such as some students like to come on difficult challenges, because some of them are anxious to find work, study up on the quick success is inevitable, cart before the horse, such as direct-depth source code, this is actually not advisable to impose one-sided interpretation, also to no avail.
As mentioned earlier, since the Java eco-Spring integration is complete, and it is huge. Under the premise of the time constraints, the face of a broad array of technology systems, methods need to figure it out, need to turn to overtake experience, need to practice to consolidate the results.
To everyone better enhance their own, suggest that you first learn based on the following map, to see their own deficiencies, lack of timely completion, Spring mind map below, on the front are not interested can skip; mind map can be self save, you can private letter Xiaobian [learning] acquired brain maps and related information
