将具有Avro字段的对象转换为json

Question

I have the following code to convert an object to Json:

public static Function<Object, Object> WRITE_JSON = (Object val) -> {
    try {
        return new ObjectMapper().writeValueAsString(val);
    } catch (IOException e) {
        // log exception
        return "";
    }         
}

This works fine for most cases, but fe I have an Avro class named AvroData , and a class that saves it:

class SomeData {
    private AvroData avroData;
    // more fields, getter/setter boilerplate, etc...
}

When I try to serialise the object to Json , this fails when trying to serialize the Avro field. In reality, I have a bit more data, like Set s and Map s that contain Avro record values, but I think the point stands.

How do you manage to serialise a avro to json, but specifically when it's part of a Non-avro object?

To convert your Object val in JSON with Jackson:

ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String json = ow.writeValueAsString(val);
