Generate Json Schema from POJO with a twist

Question

What I have:

I\'m generating a JSON schema from a pojo. My code to generate the schema looks like so:

ObjectMapper mapper = new ObjectMapper();

Answer 1

It seems to not be possible using the instructions I found using databind. However I found another jackson module that seems to do the trick nicely. Oddly several of the objects are named the same.

TLDR: use objects from the org.codehaus.jackson.map package rather than the com.fasterxml.jackson.databind package. If you're following the instructions on this page then you're doing it wrong. Just use the jackson-mapper module instead.

Here's the code for future googlers:

private static String getJsonSchema(Class clazz) throws IOException {
    org.codehaus.jackson.map.ObjectMapper mapper = new ObjectMapper();
    //There are other configuration options you can set.  This is the one I needed.
    mapper.configure(SerializationConfig.Feature.WRITE_ENUMS_USING_TO_STRING, true);

    JsonSchema schema = mapper.generateJsonSchema(clazz);

    return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(schema);
}
