Comparison of Valid and Validated in Java

If you want to add interface validation, you need

1. Add the @ Valid annotation before the request parameter in the interface method, without adding the @ Valid annotation on the implementation class of the interface, and without the @ Validated annotation:

addAnimal(@Valid Animal a)

2. Add the @ Valid annotation on each field to be validated in the request object class, and you don't need to add the @ Validated annotation on the class:

public class Animal{
@Valid
@NotEmpty
private String name;
}

Validated is an extension of Spring to Valid of javax. validation, adding the function of supporting packet verification, but not nested verification.

Valid supports nested validation, such as:

@Valid
private List<Animal> list

Extension of knowledge points:

@ Valid is used when using hibernate validation

@ Validated is used only with the spring Validator verification mechanism
