hibernate-validator VS Hibernate

Why not use some tool like https://hibernate.org/validator/ ?

Without attempting to define 'right mind', Hibernate validator uses regex based email validation.

Our microservice accept http requests: For swagger used Swagger OpenAPI 3. The bank account REST controller, which accept requests, validate it using Hibernate Validator, then call command or query service. The main reason for CQRS gaining popularity is the ability to handle reads and writes separately due to severe differences in optimization techniques for those much more distinct operations.

I'm trying to build a specific sub module of an open source library.

And Hibernate ORM is LGPL: see the license on their Github project.

13. Hibernate

Hibernate is the umbrella for a collection of libraries, most notably Hibernate ORM which provides Object/Relational Mapping for java domain objects. In addition to its own "native" API, Hibernate ORM is also an implementation of the Java Persistence API (jpa) specification.

I'm using Spring Data JPA as a persistence framework. Therefore, those classes are Hibernate entities.

Hibernate -- https://hibernate.org (huge learning curve)

This video is a crash course into the Hibernate & JPA universe.

To prevent SQL Injection attacks to sanitize input data. You can either validate every single input or validate using parameter binding. Parameter binding is mostly used by developers as it offers efficiency and security. If you are using a popular ORM such as sequelize, hibernate, etc then they already provide the functions to validate and sanitize your data. If you are using database modules other than ORM such as mysql for Node or Mongoose, you can use the escaping methods provided by the module. Let's learn by example. The codebase shown below is using mysql module for Node.
