如何将json模式转换为avro模式 [英] How to convert json schema to avro schema

问题描述

我的应用程序一直在使用json模式(org.everit.json.schema.Schema)来验证JSON消息是否符合特定格式.我们现在正在考虑转向Avro模式.这涉及将先前存储的schema.json文件转换为要转换为Avro schema schema.avsc的文件.另外，当前行为是我们使用SchemaLoader(例如SchemaLoader.load(JSONObject obj))对其进行验证后，通过API/schema/create获取JSON格式的架构，并将其存储为schema.json格式.

My application has been using json schema (org.everit.json.schema.Schema ) to validate JSON messages whether they comply to a particular format. We are now thinking of moving to the Avro schema. This involves converting previously-stored schema.json files to be converted to Avro schema schema.avsc. Also, the current behavior is we get schema in JSON format via an API /schema/create and store it schema.json format after validating it using SchemaLoader, for example, SchemaLoader.load(JSONObject obj).

当我们通过API接收到运行时时，我们还需要一种将该schema.json转换为schema.avsc的方法.有什么工具或工具可用于将schema.json转换为schema.avsc?

We also need a way to convert this schema.json to schema.avsc as we receive it run time via API. Is there any utility/tool we can use to convert the schema.json to schema.avsc?

推荐答案

看看 json- GitHub上的avro-converter .它包括一个简单的命令行界面，用于在Avro和JSON之间进行验证和转换.

Take a look at json-avro-converter on GitHub. It includes a simple command line interface for validating and converting between Avro and JSON.

JSON到Avro
java -jar json2avro-validator.jar -s user.avcs -i user.json

JSON to Avro
java -jar json2avro-validator.jar -s user.avcs -i user.json

Avro转换为JSON
java -jar json2avro-validator.jar -s user.avcs -i user.avro -m avro2json

Avro to JSON
java -jar json2avro-validator.jar -s user.avcs -i user.avro -m avro2json
