Summary: ConstructorProperties with custom-named fields
(JohnzonProperty)
Key: JOHNZON-200
URL: https://issues.apache.org/jira/browse/JOHNZON-200
Project: Johnzon
Issue Type: Bug
Components: Mapper
Affects Versions: 1.1.11
Reporter: Alexander Falb
I'm not sure if this is a bug or just unexpected behaviour:
When I map a JSON field named "$version" to a Java field named "version" and
this field is mandatory/final I have to annotate the constuctor like this:
{code:java}
public static class MyBean {
@JohnzonProperty("$version") private final int version;
@ConstructorProperties("$version") public MyBean(int version) {
this.version = version;
}
...{code}
I would expect the value of {{ConstructorProperties}} to be {{version}}
(without the dollar $ sign), because the documentation of
{{ConstructorProperties}} says:
{quote}An annotation on a constructor that shows how the parameters of
that constructor correspond to the constructed object's getter
methods. [...]
{quote}
but is actually has to be the JSON field name.
In my optinion this is quite unexpected and also from a maintainability point
of view I think declaring the custom naming twice is bad. - I think the
{{ConstructorProperties}} should the the Java field names and not the JSON name
(or for backward compatability maybe both).
