Spring / Spring Boot
How does Spring Boot handle data validation?
In Spring Boot, data validation can be performed using various mechanisms. One common approach is to use the validation annotations provided by the Bean Validation API, such as @NotNull, @Size, and @Pattern
, on the fields of model objects.
By including the necessary validation annotations, Spring Boot automatically validates the input data and generates validation errors. These errors can be handled using BindingResult or Errors objects. Additionally, custom validation logic can be implemented by creating custom validation classes and methods.
