Spring Boot - Bean Validation 2.0 Validation of a list of objects

Question

I am using springBoot 2 and I am trying to validate the objects in a List via:

@RequestMapping(value = "/bets",
    produces = {"application/json"},
    consumes = {"application/json"},
    method = RequestMethod.POST
)
void postBets(@RequestBody List<@Valid Bet> bets);

and Bet class has @NotNull annotations on certain attributes.

import javax.validation.constraints.NotNull;

public class Bet extends BetMessage {

@NotNull
private String categoryName;

@NotNull
private String marketName = null;

@NotNull
private OffsetDateTime startTime = null;

@NotNull
private String betName = null;

I have also added the spring-boot-starter-validation artifact to my build file but still no validation is happening.

As a workaround I have implemented the popular answer in the question below (ValidList class) and validation is working as expected; however I think that I am missing something obvious and the solution is now part of the validation library.

Did you try changing `List<@Valid Bet> bets` into `@Valid List bets`? — Jakub Pogorzelski, Sep 26 '18 at 10:36
@JakubPogorzelski yes - tried both ```@Valid List bets``` and ```@Valid List<@Valid Bet> bets``` but neither have worked — JoeyHolloway, Sep 26 '18 at 10:59
you may check Chapter 2 of the documentation https://docs.jboss.org/hibernate/stable/validator/reference/en-US/pdf/hibernate_validator_reference.pdf — Sharman25, Oct 02 '18 at 18:13

You may want to write a wrapper which contains your list of Bet because then your wrapper will conform to JavaBean specs and the validations can be applied.

Below Answer might help in this case.
