“It compiles. It runs. But why doesn’t the JSP page update?” Fluent setters are tempting—but in legacy stacks, they can cause subtle, hard-to-find bugs.
Sergei Chernov’s guide helps weigh the risk—before prod breaks: https://javapro.io/2025/10/01/fluent-setter-breaking-the-convention/
Fluent setters reduce boilerplate, reveal object hierarchies, & simplify nested DTOs. But can they play nicely with inheritance? And what does the JavaBeans spec actually allow?
A deep dive into real code by Sergei Chernov: https://javapro.io/2025/10/01/fluent-setter-breaking-the-convention/
Want to use fluent setters in DTOs? #Spring Boot, Jackson & MapStruct support them. But java.beans.Introspector, JSP tags & legacy EE apps may silently fail.
Sergei Chernov maps the compatibility landscape. Read before refactoring: https://javapro.io/2025/10/01/fluent-setter-breaking-the-convention/
Is returning this from a setter harmless—or a silent bug? Fluent setters promise clean code, but can break conventions in #Java beans.Introspector, Commons-BeanUtils & more.
Sergei Chernov shows where they break & shine: https://javapro.io/2025/10/01/fluent-setter-breaking-the-convention/

New post: Fluent Internals
Part 4 of Crafting Fluent APIs dives into the type design behind RestClient: self-bounded generics, fluent states, and how the API stays clean on the surface.

New post: Responding to Real Usage
In Part 3 of Crafting Fluent APIs, I share how a conference demo led to a last-minute fix in WebClient's fluent API. Watch how people use your API, then improve it.

🔧🔨 Builder Design Pattern in .NET C# 🚨
A step by step guide to develop a Fluent API from scratch in .NET C# using the Builder Design Pattern.
In this article, we would walk through the whole process of developing a Fluent API using the Builder Design Pattern, from the early steps of thinking about it, to the latest of testing it.
⁉️ What is the Builder Design Pattern?
It is a creational design pattern which allows creating complex objects into small simple steps one by one.

For #Java, I would replace the last one with
"3. expert/never-hipster: uses jOOQ"
When I discovered #jOOQ years ago, it was eye-opening. One can really get the same level of control as with hand-written #SQL bit still have a comfortable API! Its author @lukaseder says that the guiding principle for designing this #FluentAPI is that jOOQ *is* SQL.
