preface

Tiktok delicacy often sees what some foreigners are asking for what they want to bring back to their country. I have heard many answers: Taobao, Alipay, food, WeChat, takeaway, high speed rail and so on.

Indeed, with the rapid development of the country, it has attracted many envious eyes in the world, and made China's four new inventions go to the world. Speaking of these, it is inseparable from the support of the huge Internet system behind it. As the top Internet enterprise in China, Alibaba must also gather top IT talents in the industry.

As we all know, Alibaba's main development language is Java, and for Java developers, the most important thing is to learn the Spring framework. Now, I want to share with you the notes of Ali technical officer Spring family bucket, which foreigners can't help admiring. Let's have a quick look.

As we all know, the most important thing to learn Spring is its core ideas AOP and IOC. These two contents are also taken out separately to make a note to focus on. See it first!

Due to space constraints, these two knowledge points talk a lot about dry goods. Here, only part of the document content can be intercepted and displayed, and the full version can be obtained on it. Thank you for your cooperation.
