Preface:
With the development of the Internet, the cycle of technological update is getting shorter and shorter, and the development and promotion of emerging technologies are getting faster and faster. For developers, the emergence of a series of open source frameworks has played a great role in their work. When it comes to open source framework, I believe everyone is most familiar with the Spring family. As the most popular framework technology, basically Internet enterprises are using it, including a series of leading Internet companies led by Alibaba.
Therefore, it is necessary for developers in the Internet industry to learn Spring, and now basically Spring is also a knowledge point that will be asked in the interview. However, for fresh graduates or those with 1-2 years of work experience, the knowledge of the Spring family is far from enough, and the word “proficient” on a resume may take a lot of work.
If you want to master Spring, take a look at the 367-page PDF, which I think is the best interpretation of the Spring family.

In the Yangtze river waves behind push on those before. ** The Development of the Internet is so fast, technology changes with each passing day, update iteration has become synonymous with this era, adhere to the technical system will be more and more robust, Spring as a popular framework technology, if you have not mastered, not to mention the new technology after the update.
So, no matter what your age as a developer, it’s important to learn new skills.
