如何使用 json 模式生成内部 Java 类？

Question

Is it possible to generate inner java classes using json schema? The plugin I am using for generating my pojos is jsonschema2pojo( http://www.jsonschema2pojo.org/ )

If yes, how?

Currently I couldn't find any information/examples regarding this on web, neither on http://json-schema.org/ or on http://www.jsonschema2pojo.org/

Answer 1

No. I have experimented with this trying to achieve the same and have concluded that jsonschema2Pojo doesn't support it.

Neither

{
...
   "foo": {
      "$ref" : "#/definitions/Bar.Foo"
   }
...
"definitions" : {
   "Bar.Foo": {
      "type": object,
      ...
   }
}

or

{
...
   "foo": {
      "$ref" : "#/definitions/Foo"
   }
...
"definitions" : {
   "Foo": {
      "type": object,
      "javaType": "org.example.Bar.Foo"
      ...
   }
}

works.

I'd recommend posting this issue to their jira, last time I checked they were quite responsive.

You might also want to consider other limitations of jsonschema2Pojo and think about whether the tool makes sense at all.

On the project I have been working on it is becoming more more clear that we might have been better off not using the tool at all, because people have been inventing all kinds of exotic workarounds to compensate for shortcomings of the tool (like being able to specify a base class for a generated class.
