Want to change @JsonProperty property in the java model which is being created from TypeSpec.

[shikshartin-coder]

So basically as the title suggests. I looked up some decorators docs to see if I can use those to modify what property is being set in @JsonProperty in the Java file for various fields. But the example used was of console.log. The only way I found to set some metadata to the decorators was through stateMap or stateSet which uses key. But I don't think any key is required in my scenario. Is there any way to change @JsonProperty from the field name when creating a model ?

I'm sorry I don't understand what you are trying to do. Can you say more, or give an example of the output you are seeing and how you want to change it?

I am not sure whether I get the question.

I assume you are talking about a property with name e.g. "foo" in TypeSpec, but you want @JsonProperty("bar") instead for it.

There is an @encodedName decorator that modifies the "wire name" (the name of the property in the JSON payload).
E.g. https://github.com/Azure/typespec-azure/blob/main/packages/azure-http-specs/specs/client/naming/main.tsp#L37-L38
It means, when serialize/de-serialize for "application/json" content-type, use "wireName" as JSON property name, instead of "defaultName".

Note that the latest version of the http-client-java emitter no longer use Jackson (hence no @JsonProperty).
