使用jsonschema2pojo只会创建List<Object>，没有更复杂的内容。

问题

我试图使用jsonschema2pojo来生成Java对象，但是我的对象数组只生成了一个List<Object>，而不是一个新的映射对象。是否有配置设置需要提供？

在下面的示例中，我期望一个名为OtherLanguages的POJO，以及一个public List<Object> otherLanguages字段。

示例JSON：

  1. {
  2.     "firstName": "testfirst",
  3.     "lastName": "testlast",
  4.     "birthCountry": {
  5.         "value": 3,
  6.         "label": "Afghanistan (AF)"
  7.     },
  8.     "otherLanguages": [{
  9.             "value": 218,
  10.             "label": "Uzbek (UZB)"
  11.         },
  12.         {
  13.             "value": 216,
  14.             "label": "Ukrainian (UKR)"
  15.         }
  16.     ]
  17. }

生成的模式（使用https://jsonschema.net生成）：

  1. {
  2.     "$schema": "http://json-schema.org/draft-07/schema",
  3.     "$id": "http://example.com/example.json",

I'm trying to use jsonschema2pojo to generate java objects, but my array of objects is just producing a List&lt;Object&gt; not a new, mapped object. Is there a config setting I need to provide?

In the below example, I was expecting an OtherLanguages POJO, and a public List&lt;Object&gt; otherLanguages; field.

example JSON:

  1. {
  2.     &quot;firstName&quot;: &quot;testfirst&quot;,
  3.     &quot;lastName&quot;: &quot;testlast&quot;,
  4.     &quot;birthCountry&quot;: {
  5.         &quot;value&quot;: 3,
  6.         &quot;label&quot;: &quot;Afghanistan (AF)&quot;
  7.     },
  8.     &quot;otherLanguages&quot;: [{
  9.             &quot;value&quot;: 218,
  10.             &quot;label&quot;: &quot;Uzbek (UZB)&quot;

将创建 JSON Schema 时的数组验证更改为 First，然后它将变成一个严格的对象。

查看截图

英文:

Change Array Validation to First when creating JSON Schema, then it will become a strict object.
