Java Ninja Chronicles By Norris Shelton

Things I learned in the pursuit of code

I was migrating some old Jackson code to Jackson 2 (FasterXML). I ran into where they were telling the Jackson to ignore unknown properties via code.

ObjectMapper mapper = new ObjectMapper();
mapper.getDeserializationConfig().set(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);

The new way to do this in Jackson 2 (FasterXML) is

ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
