[英]Generate JSON Schema from JSON using Java
Is there any Java package which I can use to convert a JSON string to JSON schema?是否有任何 Java 包可用于将 JSON 字符串转换为 JSON 模式? I have looked up online.
我在网上查过。 I found libraries in Python, Ruby and NodeJS, but not in Java
我在 Python、Ruby 和 NodeJS 中找到了库,但在 Java 中没有
All the Java libraries generate JSON schema from a POJO所有 Java 库都从 POJO 生成 JSON 模式
I think that you can try this library on github it does exactly what you want from a JSON, You only need to build it and use json-string-schema-generator我认为你可以在 github 上尝试这个库,它完全符合你想要的 JSON,你只需要构建它并使用json-string-schema-generator
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");
}
