Join Ketkee Aryamane for an in-depth discussion in this video General default settings, part of Java EE 8: JSON-B.
- [Instructor] Now that we've seen the simplest demo…where we created a simple user bean…and converted that to JSON and back to Java,…let's look at the general default settings…that the JSON Binding API is going to apply…when it tries to do serialization.…The first one is the property naming.…When you talk about the JSON document generation,…of course, we know that JSON has name and value pairs.…Where does it pick up those names from, those keys from?…So, the names are always as per the instance variables…in the beans that you have defined.…
And those are the ones that are picked up…during serialization.…So, let's go and check it out in our demo also.…We have this User bean.…And if you look at the User bean,…those were the properties that you've defined…from lines 16 to 19.…And if you look at your JSON representation,…the instance variables are exactly the keys…that were picked up for the serialization process.…So, when your Java object got converted to a JSON document,…the keys will be the instance variables.…
