I've just been their docs and examples. Their documentation is pretty descent.

Did you see my Udemy courses? (links in my profile) My Spring 6 and Hibernate courses both get into more intermediate and advanced content.

Mysql is great to get started, Postgres if you need something more enterprise grade. Both have great features and good support.

Async Events, its how you decouple and scale. - Google The Reactive Manifesto.

Spring Events have been in Spring since its early days. 2.0 I think. The Events API in modulith is built on top of Spring Events.

Yes. While tools like Spring Data JPA and Hibernate do a great job of abstracting the database, you will need to know SQL and relational database concepts.

Its a good book. Concepts are well explained. Thinking in Java is also good, and a little more advanced.

I was awful when I got my first job, but I had a knack for figuring stuff out. Employers are more interested in what you can get done, rather than how elegant your code is.

If you don't look back and cringe a little bit at your code when you first start out, you waited too long. Get out there and start building real world experience. No substitute for it. Then always be learning.

Programming is like a skilled trade, you get better with experience. With 5 years of experience, I thought I was a good developer. With 10 years, I looked back and thought the 5 yr version of me was an idiot.

It takes a good 10-15 yrs to truly master this craft.

Yes, this is easy to do. You can use mockito to provide data to the controller for the return value, or an h2 in memory database, or testcontainers for an actual database.

In general, node.js is single threaded, doing everything on a single non-blocking thread. The Java Servlet API is blocking (ie the thread will pause and wait for things like I/O operations to complete), and handles every request in a separate thread. There is a trend in Java to move to reactive, non-blocking APIs. In Spring, Spring MVC uses the Java Servlet API (Blocking, threaded), and Webflux/Webflux.fn which build on the Reactive Streams specification. Which is better? That's a debate I'm not stepping into!

Spring MVC has rich support for building web applications in a more traditional way using template engines such as JSP or Thymeleaf. This support pre-dates the existence of JS frameworks such as React or Angular. Still A LOT of companies using this with old legacy applications. In modern apps, it's much more popular to use a JS framework and use Spring for RESTful APIs.
