Mapping a Json variable with "-" to Java property

Question

I am calling a rest service which returns a JSON Object and one the field is error-codes. Now how do I declare a variable in Java as '-' is not allowed.

The JSON is as follows

 {
      "success": true|false,
      "error-codes": [...]       
    }

This didn't worked

private List<ErrorCodes> errorCodes;

nor

private List<ErrorCodes> errorcodes;

That probably depends on the mapper library you're using. Care to tell us? — Thomas, Oct 24 '17 at 14:05
I think you can cleverly do one thing, just get the response and replace "error-codes" to whatever value you want and then map it object which you want. It should work — Vipul Jain, Oct 24 '17 at 14:05
@Vipul that is not clever, it's a pretty ugly workaround. But yes, since it works, it's probably clever. — f1sh, Oct 24 '17 at 14:10

You must be using a JSON parser such as Jackson. In this case use:

@JsonProperty("error-codes")
private List<ErrorCodes> errorCodes;

You didn't mention what kind of deserializer you use. Most deserializers work with some annotations on the fields. For example in Jackson, you could do:

@JsonProperty("error-codes")
private List<ErrorCodes> errorCodes;
