OpenAPI 生成器 Maven 插件 Bean 验证 MinProperties 验证

Question

我有一个使用 Java 11 的 Spring Boot (2.4.0) REST 服务。端点和对象是使用 openapi-generator-maven-plugin v5.0.1 从 OpenAPI 3.0.3 文件生成的

在 API 中，有一个 GET 请求需要两个查询参数。其中至少必须有一名在场。此示例提到使用 minProperties。尽管我已在 OpenAPI 文件中指定了minProperties，但自动生成的对象不会验证这一点。有办法让它发挥作用吗？

OpenAPI 3.3 代码片段：

parameters:
- in: query
  name: id
  required: true
  style: form
  explode: true
  schema:
    title: EntityId
    type: object
    properties:
      businessId:
        type: string
      nonBusinessId:
        type: string
    minProperties: 1
    additionalProperties: false

    sb.append("    nonBusinessId: ").append(toIndentedString(nonBusinessId)).append("\n");
    sb.append("}");
    return sb.toString();
  }
