Validate MongoDB documents through Spring boot data

Question

I'm new to MongoDB. I'm using Spring boot 2.1.3.RELEASE.

I want to perform validation on MongoDB documents (on message as per below code), currently, it saves documents even everything passed as null.

I have gone through a couple of answers like Spring data mongoDb not null annotation like Spring data Jpa

public class Comment {

  @NotBlank(message = "Comment's message can't be blank")
  private String message;
  
  @CreatedDate
  private Date createdDate;

  @CreatedBy
  private String createdBy;

}

Is there any way to achieve the same without using hibernate-validator dependency?

Answer 1

i was with the same problem and found this question. Here is how i solved my problem in my application that uses Spingboot e MongoDB

this is the only dependency needed.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

The DTO class with the rigth imports

And in the controller i used @Validated from

import org.springframework.validation.annotation.Validated;

    @PostMapping
@ResponseStatus(HttpStatus.CREATED)
public ProdutoData inserirProduto(@RequestBody @Validated ProdutoForm produto){
    return produtoServico.salvar(produto);
}

I hope this can help someone.
