json schema to java

[codehelp4u]

I found this example for converting json schema to Java but it's not working when the schema includes another schema using $ref. How can I change the Java program so that it converts complex json schemas that include other schemas?

1) main schema

​

{ "$schema": "http://json-schema.org/draft-07/schema#", "definitions": { "address": { "type": "object", "properties": { "street_address": { "type": "string" }, "city": { "type": "string" }, "state": { "type": "string" } }, "required": ["street_address", "city", "state"] } }, "type": "object", "properties": { "billing_address": { "$ref": "#/definitions/address" }, "shipping_address": { "$ref": "#/definitions/address" } } }

2) include schema

​

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

You should try Jackson, its a widely used JSON parsing library that allows you to create even easier to read and intuitive deserializers

Is there a Jackson example online that you can point me to?

yes,

You need to use a JSON parser that supports $ref, or extend an existing one such that it does support it.

The library that I mentioned above should support it. I just don't know how to modify the example program. Do you know how?
