Make json plugin more extendable
--------------------------------
Key: WW-3780
URL: https://issues.apache.org/jira/browse/WW-3780
Project: Struts 2
Issue Type: Improvement
Components: Plugin - JSON
Affects Versions: 2.3.1.2
Reporter: Pelladi Gabor
Priority: Minor
Currently it is difficult to modify/extend the current behaviour of the json
plugin.
I had the following problem. We use joda-time because it is much better than
standard Date. The json plugin cannot handle classes like LocalDate, which is
not a problem in itself. But it needs a lot of boilerplate code to output beans
containing a LocalDate field using json. Currently I have to create duplicates
of the service layer DTO-s, annotate the fields in the UI copy with
@JSONFieldBridge, and copy one DTO into the other using dozer or something.
This creates a lot of useless code and manual work. It would be much easier if
I could extend JSONWriter and add support for my joda-time classes. No
duplication of DTO-s, no need to manually annotate all fields. This would
require only to modify the visibility of some private methods to protected, and
some package-protected classes to public. This way I could create my struts2
result type, which extends JSONResult, and use my writer, which extends
JSONWriter.
