Hello, I’m Hollis

I’m sure most of my readers know that I’ve summarized the Java Engineer’s Path to God, which was first written in 2015 and has been updated to version 2020 after five years of iteration.

I believe many people follow me because of this article. There are many people, many, many people, who have expressed to me on wechat or in person that The Road to Becoming God has helped them a lot.

Many of Ali’s colleagues have also been mentioned many times.

Hearing these words, I was really indescribably happy. At the beginning, I never thought that a little effort of my own could help a confused person thousands of miles away.

This article is just a directory at the beginning, in order to facilitate you can see the complete Java system knowledge points, to help you check the missing.

Then, in 2019, I decided to start gradually refining the content, which led to the open source project ToBeTopJavaer (github.com/hollischuan…). .

The project has also received a lot of attention and now has a 17.4K Star on GitHub

After reading in order to facilitate everyone, I have to put them into Gitee (hollischuang. Gitee. IO/tobetopjava…). And dead simple. Io (hollischuang. Making. Io/toBeTopJava…). The above.

Now on these two online reading sites, a total of more than 200,000 people (Gitee 160,000, Github. IO 70,000) read, the total number of visitors is nearly 150,000.

In the process, many readers asked me if I would consider a physical book, and many said they would buy it at any price.

In this process, many publishers contacted me, but on the one hand, due to the time, on the other hand, I think the content is not mature enough, so there has been no final conclusion.

Until some time ago, a colleague from Ali Cloud approached me and asked if I would like to work with the Ali Cloud Developer community on this book, and I gladly agreed.

As can be seen from Dingding’s chat records, it has been half a year since THE first contact to prepare this book.

Today, I am happy to announce that the book is now available as a free PDF!!

There is so much in the book that it still contains the basics of Java Engineer To God, but that alone is now nearly 400 pages long.

I know that no one can finish a thousand-page book, so I’ve broken it down into sections, and the first part is sorted out and shared.

The book was finished last Friday. At first, the editor of Aliyun told me that it would be published on Aliyun on Friday. Later, I did not pay attention to it because I was busy.

But in the evening, wechat exploded and many people left messages to me, saying that my e-book had been on the front page of ali Cloud developer community for a whole day…

Not only that, but also once in the CSDN recommended list.

During the weekend, I took a look at the data. The landing page of ali Cloud developer community has already received 15,000 views.

Thanks again to all the readers for their support and I hope the content in this book will be helpful.

And finally, I kind of like this cover that my colleagues at Aliyun did for me, and I really like it, the lone swordsman.

Ten steps kill a man. Things brushed clothes to go, deep hiding with the name.
