Ant Financial is a bit "ruthless" and forced me to thoroughly understand the Spring source code (with study notes)

Successfully landed on Ant Financial

Due to the epidemic this year, most companies are facing the risk of bankruptcy and integration, and many large companies have issued announcements of layoffs. And how programmers stand out in the situation of oversupply has become the biggest problem for programmers this year. These situations are indeed no small trouble for me.

I am a graduate who graduated last year. I was doing Java development in a listed company a year ago, mainly in charge of e-commerce projects. After half a year of work, I accumulated some work experience. Unexpectedly, in March of this year, the company issued a layoff notice, and my name unexpectedly appeared on the list. After spending 2 months at home, I worked hard in the source code, and finally successfully landed on Ant Financial at the end of April.
