jsonschema2pojo：引用相同类型的对象

Question

我需要从JSON模式文件生成Java类，并遇到jsonschema2pojo。但是，我遇到了一个＆＃34;问题＆＃34;使用ref关键字时。

例如，如果我使用http://spacetelescope.github.io/understanding-json-schema/structuring.html#extending中的以下架构：

{
  "$schema": "http://json-schema.org/draft-04/schema#",

  "definitions": {
    "address": {
      "type": "object",
      "properties": {
        "street_address": { "type": "string" },
        "city":           { "type": "string" },
        "state":          { "type": "string" }
      },
      "required": ["street_address", "city", "state"]
    }
  },

  "type": "object",

  "properties": {
    "billing_address": { "$ref": "#/definitions/address" },
    "shipping_address": { "$ref": "#/definitions/address" }
  }
}

正如所料，它生成了一个名为您想要调用它的类，包含属性billingAddress和属性shippingAddress。

但是，它还生成了两个单独的类BillingAddress和ShippingAddress，即使这两个属性都引用了address。因此，我宁愿同时拥有Address类型的两个属性。

这可以用jsonschema2pojo实现吗？

更新

从here更好地了解javaType之后。我通过在地址定义中添加一个javaType来获得预期的结果。

{
  "$schema": "http://json-schema.org/draft-04/schema#",

  "definitions": {
      "address": {
      "type": "object",
      "javaType": "Address",
      "properties": {
        "street_address": { "type": "string" },
        "city":           { "type": "string" },
        "state":          { "type": "string" }
      },
      "required": ["street_address", "city", "state"]
    }
  },
  "type": "object",
  "properties": {
    "billing_address": { "$ref": "#/definitions/address" },
    "shipping_address": { "$ref": "#/definitions/address" }
  }
}

回答两个文件

您需要在Address.json中使用 javaType ，并使用 $ ref 作为billing_address和送货地址。我建议你将地址定义分成一个单独的json，然后在你的billing_address和shipping_address中使用它。

Address.json

{
    "$schema": "http://json-schema.org/draft-03/hyper-schema",
    "additionalProperties": false,
    "javaType": "whatever-package-name-you-have.Address"
    "type": "object",
    "properties": {
    "street_address": { "type": "string", "required":true},
    "city":           { "type": "string", "required":true },
    "state":          { "type": "string", "required":true }
  }
}

MainClass.json

{
    "$schema": "http://json-schema.org/draft-03/hyper-schema",
    "additionalProperties": false,
    "type": "object",
    "properties": {
     "billing_address": {
           "$ref":"Address.json",
           "type": "object",
           "required": false
          },
     "shipping_address": {
           "$ref":"Address.json",
           "type": "object",
           "required": false
          }
     }
}
