Avoid the underscore classes

[hari...@gmail.com]

I am trying to generate pojos for a json like this 

{
    "order": {
        "id": "1234",
        "objType": "order",
        "priceInfo": {
            "currencyFormat": "$0.00",
            "currency": "USD",
            "amount": "70.91",
            "isDiscounted": true
        },
        "shippingGroups": [
            {
                "id": "1234",
                "objType": "shippingGroup",
                "priceInfo": {
                    "currencyFormat": "$0.00",
                    "currency": "USD"
                }
            }
        ]
    }
}

the generator ends up creating two clasees PriceInfo and PriceInfo_

What would be the best way to just generate one PriceInfo. Also in some cases i might have the second priceInfo object have an extra property. I would like to have one PriceInfo with 3 properties rather then two price info objects.

I am willing to modify the code and submit a Pull request.

Thanks in advance for your time.

Hi Harish. The way to achieve this is to define priceInfo once in the schema, then use a $ref when you want to refer to priceInfo again.

Thanks Joe. Appreciate the tip.  i got it working correctly with the schema below. Hopefully it will benefit someone.

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "id": "/",
    "type": "object",
    "properties": {
        "order": {
            "id": "order",
            "type": "object",
            "properties": {
                "id": {
                    "id": "id",
                    "type": "string"
                },
                "objType": {
                    "id": "objType",
                    "type": "string"
                },
                "priceInfo": {
                    "$ref": "#/definitions/priceInfo"
                },
                "additionalProperties": false
            },
            "shippingGroups": {
                "id": "shippingGroups",
                "type": "array",
                "items": {
                    "id": "0",
                    "type": "object",
                    "properties": {
                        "id": {
                            "id": "id",
                            "type": "string"
                        },
                        "objType": {
                            "id": "objType",
                            "type": "string"
                        },
                        "priceInfo": {
                            "$ref": "#/definitions/priceInfo"
                        }
                    },
                    "additionalProperties": false
                }
            }
        },
        "additionalProperties": false
    },
    "additionalProperties": false,
    "definitions": {
        "priceInfo": {
            "id": "priceInfo",
            "type": "object",
            "properties": {
                "currencyFormat": {
                    "id": "currencyFormat",
                    "type": "string"
                },
                "currency": {
                    "id": "currency",
                    "type": "string"
                }
            },
            "additionalProperties": false
        }
    }
}

Harish, I have the same problem, how do you generate the JSON schema from JSON?

[hari...@gmail.com]

You can use this site 

http://jsonschema.net/#/

And when i use it , i select Single Schema and uncheck everything.

[HUANG Wei]

Hi again, what about the $ref part? It's it done manually?

[Dan Tran]

I have one more interesting scenario

{

  "type" : "object",

  "properties" : {

    "attributes" : {

      "type" : "object",

      "additionalProperties" : {

        "type" : "string"

      }

    },

    "links" : {

      "type" : "array",

      "required" : true,

      "items" : {

        "type" : "object",

        "link": {

          "$ref": "#/definitions/link"

        }

      }

    },

    "id" : {

      "type" : "string",

      "required" : true

    },

  "definitions": {

    "link": {

      "type" : "object",

      "properties" : {

        "rel" : {

          "type" : "string"

        },

        "href" : {

          "type" : "string"

        },

        "id" : {

          "type" : "string"

        }

      }

    }

  }

}

It generates a Link classname  ( for the array) and Link_ for the item class.  Is there a way to force the array class to be named as Links???

Very much in need for this to work

Thanks

[Dan Tran]

2 more issues

  1. The generated java class for 'links' is very vague, it has nothing to with the array of Link_ class

  2. If I place the 'link' schema to another file and reference it via "$ref": "Link.json". Then only one class generated - the vague array class

Thanks

You can use javaType to force jsonschema2pojo to generate the name you desire.

Here is my revised schema for your example.  I also attached the Example.jsonschema based on the content below and its generated Java classes.

{
  "type" : "object",
  "properties" : {
    "attributes" : {
      "type" : "object",
      "additionalProperties" : {
        "type" : "string"
      }
    },
    "links" : {
      "type" : "array",
      "required" : true,
      "items" : {
        "type" : "object",
        "link": {

          "$ref": "#/definitions/Link"

        }
      }
    },
    "id" : {
      "type" : "string",
      "required" : true
    }
  },

  "additionalProperties" : false,
 
  "definitions": {
    "Link": {

      "type" : "object",
      "properties" : {
        "rel" : {
          "type" : "string"
        },
        "href" : {
          "type" : "string"
        },
        "id" : {
          "type" : "string"
        }

      },
      "additionalProperties" : false

    }
  }
}

the working schema is 

{
  "type" : "object",
  "properties" : {
    "attributes" : {
      "type" : "object",
      "additionalProperties" : {
        "type" : "string"
      }
    },
    "links" : {
      "type" : "array",
      "required" : true,
      "items" : {

          "$ref": "#/definitions/Link"

        }
      }
    },
    "id" : {
      "type" : "string",
      "required" : true
    }
  },

  "additionalProperties" : false,
  

 {

      "type" : "object",
      "properties" : {
        "rel" : {
          "type" : "string"
        },
        "href" : {
          "type" : "string"
        },
        "id" : {
          "type" : "string"
        }

      },
      "additionalProperties" : false

    }
  }
}

for the external file ref to work, the content is

{

      "type" : "object",
      "properties" : {
        "rel" : {
          "type" : "string"
        },
        "href" : {
          "type" : "string"
        },
        "id" : {
          "type" : "string"
        }

      },
      "additionalProperties" : false

 }

There was mistake of my part in this external file

[thu...@emc.com]

You don't need an external file for Attributes.  You could include the definitions in the "definitions" section.  See my attached zip that contains the revised sample for your schema.

[sandeep...@gmail.com]

If I have only JSON and not JSONSchema how to avoid creation of multiple classes and create just one PriceInfo class.

[Dan Tran]

There is a couple of solution discussed previously on the same thread.  Have you looked thru it?

[Dan Tran]

How about using javaType.

No one answered for the JSON, Some one answered for JSONSchema but not only for JSON.
