Check-restcontroller advanced for client incoming data

using Hibernate validator for data validation

Bean validation annotations (need to join related dependencies, can be used directly in Springboot, Springboot will help us to join directly)

@Null Verify that the object is empty (the property must be empty and the client cannot pass in this property, otherwise it will be an error)

@NotNull Verify that the object is non-empty (the property is not empty, the customer must pass in this property, or it will be an error)

@Min Verify that number and string objects are greater than or equal to the specified value

@Max Verify that number and string objects are less than or equal to the specified value

@Size Verify that the length of the object (array,collection,map,string) is within a given range

@Past Verify that date and Calendar objects are before the current time

@Future Verify that date and Calendar objects are after the current time

@AssertTrue verifies whether a Boolean object is True

@AssertFalse Verify that the Boolean object is False

@Valid-Cascade validation annotations

Annotations can be used on member variables:

Can be used on the method:

We found that if the incoming parameter does not conform to the verification requirement, it will be returned, and through Bindingresult, regardless of whether the incoming parameter meets the requirements,

Can be passed through the bindingresult in the procedure, to be judged by the program. As follows:

The client agrees to use postman to send the request ~ ~
