json复杂模式可重用定义，忽略嵌套属性中的$ref验证

Question

试图学习JSON模式，我有一个复杂的模式，都是基于相对URL的。当嵌套属性调用另一个文件中定义的definitions属性时，验证有时会被忽略。

我的目标是基本上在全局范围内创建可重用的定义和经常使用的枚举/常量/定义

假设项目树为：

            }
          }
        }
      }
    }
  }
}

在intellij中，结果如下：（显示的每个属性都不应该是有效的，但有些属性只是被忽略和允许（如负数和空值等）。我没有收到关于$ref无法解析的警告/错误。自动完成甚至为我完成了相对的文件名和定义属性。

看起来您是在正确的轨道上，但是您不能将$ref与同一个对象中的其他关键字一起使用，因为在将$ref与draft-7 JSON模式一起使用时，这些关键字总是被忽略。

8.3.带有“$ref”的架构引用

“$ref”关键字用于引用架构，并提供通过自引用验证递归结构的能力。

如果希望在同一个模式对象中使用$ref和其他关键字，则需要创建两个模式对象并将它们封装在Allof中。
