I’m building a Spring Boot Controller with a @RequestParam array.
The thing is, the input will be a mix of Image upload (new image) and String (Existing image’s id) in the request’s body as FormData.

I recently noticed that Spring Boot 3.2 has introduced changes to its validation mechanism compared to Spring Boot 2.7.

Spring Boot is a popular framework for building Java-based applications, especially web applications. Adhering to best practices helps ensure that your code is maintainable, scalable, and efficient. Here are some best practices for Spring Boot development, along with examples:

I have the following classes:

I’m working on a Spring Boot application using JPA and Hibernate for ORM. I have a problem with lazy loading and transactions that I can’t seem to resolve.

@RequestParam(value = “grant_type”, required = true) String grantType, Resolved [org.springframework.web.bind.MissingServletRequestParameterException: Required request parameter ‘grant_type’ for method parameter type String is not present] trying to resolve the problem, why it is happening after upgradation spring spring-boot

I need to write some custom business logic that it requires to be executed before the application is deployed.
This custom business logic should re-use the existing business services together with JPA repository.

I am going through this tutorial

I use spring boot 3.3. I create a new annotation i put in a class to validate field

I’ve been writing a custom ProtocolResolver – easy enough.
Registering it via spring.factories seemed the obvious next step considering DefaultResourceLoaders Javadoc:
