spring hateoas hal-forms 可供性支持在升级到 spring boot 3 后由于 jakarta.validation 和 hibernate 版本冲突而无法工作

Question

如果您升级到 Spring Boot 3，Spring Hateoas 似乎不提供对 HAL-FORMS 中模板可供性属性验证的支持。似乎 Spring Boot 正在迁移到更新版本的休眠和 jakarta 验证 api，而 Spring Hateoas PropertyUtils 没有尚不支持。它的主要分支仍然导入javax.validation.constraints.NotNull，并且它的hibernate版本与Spring boot 3冲突。

这是一个只有 1 个文件（& pom）的非常简单的示例，它演示了它适用于 Spring boot 2.7.6（请参阅我们稍后将使用的注释掉的 spring-boot-starter-parent 版本。

            var controller = methodOn(FooController.class);
            return new ResponseEntity<>(
                    new FooRepresentation(String.format(TEMPLATE, name))
                            .add(linkTo(controller.get(name)).withSelfRel())
                            .add(linkTo(controller.post(new FooModel("foo"))).withRel("foo"))

        @NotNull
        @Length(min = 2, max = 10)
        private String name;
    }
}

如果我运行上面的命令并将我的浏览器指向 http://localhost:8080，我会得到 'required=true' 以及我期望的 FooModel.name 属性的最小长度和最大长度。我不得不调整网址，因为堆栈溢出认为它们是垃圾邮件

{
    "name": "Hello, foo!",
    "_links": {
        "self": {
            "href": "/?name=foo"
        },
        "foo": {
            "href": "/foo"
        }
    },
    "_templates": {
        "default": {
            "method": "POST",
            "properties": [
                {
                    "name": "name",
                    "required": true,
                    "minLength": 2,
                    "maxLength": 10,
                    "type": "text"
                }
            ],
            "target": "/foo"
        }
    }
}

但是如果我升级到 Spring 3.0.5（请参阅 pom 中的注释行）我必须将导入更改为 jakarta.validation.constraints.NotNull 而不是 javax.validation.constraints.NotNull 但是当我重复我的测试时我得到缺少注释驱动提示的响应。

{
    "name": "Hello, foo!",
    "_links": {
        "self": {
            "href": "/?name=foo"
        },
        "foo": {
            "href": "/foo"
        }
    },
    "_templates": {
        "default": {
            "method": "POST",
            "properties": [
                {
                    "name": "name",
                    "type": "text"
                }
            ],
            "target": "/foo"
        }
    }
}

虽然它不是很明显来自休眠的@Length（导入包没有改变）我怀疑版本冲突也是原因。

是否有一些我可以用来变通的配置，或者是否计划在 spring boot 3 中支持它？
