问题

我在验证我的Bean时遇到了问题。
我正在使用带有MongoDB的Quarkus，在尝试运行一个创建REST API时，在请求Bean之前使用了`@Valid`注解。我期望如果我想要创建一个具有`null`字段的文档（显然我在实体中使用了`@NotNull`），则会抛出异常，但实际上文档被创建而没有字段。
以下是我的代码：

Car.java：
```java
@MongoEntity(collection="cars")
public class Car extends PanacheMongoEntityBase {

    @BsonId
    private long id;
    @NotNull
    private String carName;
    @NotNull
    @Size(min = 1, max = 3)
    private String code;

    // 获取和设置方法
}

CarResource.java：

@Path("/cars")
@Consumes("application/json")
@Produces("application/json")
public class CarResource {

    @GET
    public List<Car> list() {
        return Car.listAll();
    }

    @GET
    @Path("/{id}")
    public Car get(long id) {
        return Car.findById(id);
    }

    @POST
    public Response create(@Valid Car car) {
        car.persist();
        return Response.status(201).build();
    }

我在使用@Size注解时也遇到了相同的问题，因为我可以创建一个比3个字符更长的code字段。

更新

使用quarkus-hibernate-validator时，验证可以正常工作。

现在，我需要为唯一字段找到解决方案。

此外，除了主要问题之外：是否有类似于@Indexed(unique = true)的注解？我想为我的应用程序添加一个唯一字段。

I have a problem with validation of my bean.
I&#39;m using Quarkus with MongoDB and when I try to run a create REST API, with `@Valid` annotation before request bean, I expect an exception if I want to create a document with `null` field (obviously I use `@NotNull` in entity), but document is created without field.
Here is my code:

Car.java:
```java
@MongoEntity(collection=&quot;cars&quot;)
public class Car extends PanacheMongoEntityBase {

    @BsonId
    private long id;
    @NotNull
    private String carName;
    @NotNull
    @Size(min = 1, max = 3)
    private String code;

    // get and set
}

CarResource.java:

@Path("/cars")
@Consumes("application/json")
@Produces("application/json")
public class CarResource {

    @GET
    public List<Car> list() {
        return Car.listAll();
    }

    @GET
    @Path("/{id}")
    public Car get(long id) {
        return Car.findById(id);
    }

    @POST
    public Response create(@Valid Car car) {
        car.persist();
        return Response.status(201).build();
    }

I have same problem with @Size annotation, because I can create a code field with more characters than 3.

UPDATE

Validation works with quarkus-hibernate-validator.

Now, I have to find a solution for unique field.

And besides from the main question: is there an annotation like @Indexed(unique = true)? I want an unique field for my app.
