Join Ketkee Aryamane for an in-depth discussion in this video Custom constructors, part of Java EE 8: JSON-B.
- [Instructor] Now let's take a look at the next…customized mapping option that we have,…which is how do you define a custom constructor?…Now by default, whenever the JSON binding API…tries to do deserialization,…we all know that a no argument…or a default constructor is a must.…It is going to make sure that it invokes that,…and thereafter, it'll invoke the appropriate setup methods…to set the values on the JSON document…into the respective property of your Java object.…So that's the rule.…However, there are certain situations…where this may not be the desired behavior…because the kind of JSON representation…that you're getting from some other system…may not know the structure of your beans.…
So it may send out a plain JSON…with just key-value pairs,…and it really may not have the correct object representation…that your system or your code expects.…So I'm going to talk about this situation,…this example that we have in front of us,…and then we'll go onto understand how do you solve this.…So let's go to our project structure.…
