The Baeldung Weekly Review 5

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.

I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

You can explore the course here:

DbSchema is a super-flexible database designer, which can take you from designing the DB with your team all the way to safely deploying the schema.

The way it does all of that is by using a design model, a database-independent image of the schema, which can be shared in a team using GIT and compared or deployed on to any database.

And, of course, it can be heavily visual, allowing you to interact with the database using diagrams, visually compose queries, explore the data, generate random data, import data or build HTML5 database reports.

Slow MySQL query performance is all too common. Of course it is. A good way to go is, naturally, a dedicated profiler that actually understands the ins and outs of MySQL.

The Jet Profiler was built for MySQL only, so it can do things like real-time query performance, focus on most used tables or most frequent queries, quickly identify performance issues and basically help you optimize your queries.

Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services.

Basically, you install the desktop application, connect to your MySQL server, hit the record button, and you'll have results within minutes:

Spring Data JPA is a great way to handle the complexity of JPA with the powerful simplicity of Spring Boot.

Repeatedly, code that works in dev breaks down in production. Java performance issues are difficult to track down or predict.

Simply put, Digma provides immediate code feedback. As an IDE plugin, it identifies issues with your code as it is currently running in test and prod.

The feedback is available from the minute you are writing it.

Imagine being alerted to any regression or code smell as you're running and debugging locally. Also, identifying weak spots that need attending to, based on integration testing results.

>> Enable code feedback in your IDE.

Of course, Digma is free for developers.

30% less RAM and a 30% smaller base image for running a Spring Boot application? Yes, please.

Alpaquita Linux was designed to efficiently run containerized Java applications.

It's meant to handle heavy workloads and do it well.

And the Alpaquita Containers incorporates Liberica JDK Lite, a Java runtime tailored to cloud-based services:

We rely on other people’s code in our own work. Every day.

It might be the language you’re writing in, the framework you’re building on, or some esoteric piece of software that does one thing so well you never found the need to implement it yourself.

The problem is, of course, when things fall apart in production - debugging the implementation of a 3rd party library you have no intimate knowledge of is, to say the least, tricky.

Lightrun is a new kind of debugger.

It's one geared specifically towards real-life production environments. Using Lightrun, you can drill down into running applications, including 3rd party dependencies, with real-time logs, snapshots, and metrics.
