Generates JSON Schema or POJO based from JSON data using JAVA
I have been googling a lot to find a library in JAVA that would generate me a JSON Schema based on the JSON data I have. But most of the libraries I found need to have a JAVA class in order to generate a JSON schema. So I made a simple JSON Schema Generator based on JSON data. If there is a library that already exists please let me know (via posting an Issue here) and I will be happy to use it in the current project I am working on. Thanks!
- Generates JSON Schema (output as String or File)
- Generates POJOs
Just call the static method JsonSchemaGenerator.outputAsString or JsonSchemaGenerator.outputAsFile
public class GenerateSchema { public static void main(String[] args) throws IOException { String json = "{\"sectors\": [{\"times\":[{\"intensity\":30," + "\"start\":{\"hour\":8,\"minute\":30},\"end\":{\"hour\":17,\"minute\":0}}," + "{\"intensity\":10,\"start\":{\"hour\":17,\"minute\":5},\"end\":{\"hour\":23,\"minute\":55}}]," + "\"id\":\"dbea21eb-57b5-44c9-a953-f61816fd5876\"}]}"; String result = JsonSchemaGenerator.outputAsString("Schedule", "this is a test", json); /* sample output { "title": "Schedule", "description": "this is a test", "type": "object", "properties": { "sectors": { "type": "array", "items": { "properties": { "times": { "type": "array", "items": { "properties": { "intensity": { "type": "number" }, "start": { "type": "object", "properties": { "hour": { "type": "number" }, "minute": { "type": "number" } } }, "end": { "type": "object", "properties": { "hour": { "type": "number" }, "minute": { "type": "number" } } } } } }, "id": { "type": "string" } } } } } } */ // To generate JSON schema into a file JsonSchemaGenerator.outputAsFile("Schedule", "this is a test", json, "output-schema.json"); // To generate POJO(s) JsonSchemaGenerator.outputAsPOJO("Schedule", "this is a test", json, "com.example", "generated-sources"); } }- Quennie Teves - initial work
