I am currently attempting to implement some of the tricks described in this
presentation
<https://github.com/FasterXML/jackson-docs/wiki/Presentation:-Jackson-Performance#non-compatible-easy-pojos-as-json-arrays-jackson-21>
to
increase performance. I would like to be able to change a particular
ObjectMapper instance to serialize all POJO's using a particular
JsonFormat.Shape, which I haven't been able to discover how to do.
Currently (as a POC), I'm doing something like the following:
ClassPath.from(this.getClass().getClassLoader()).getTopLevelClasses(
"my.package")
.stream()
.forEach((c) -> {
MAPPER.configOverride(c.load())
.setFormat(JsonFormat.Value.forShape(JsonFormat.
Shape.ARRAY));
});
This is obviously a temporary solution. Is there a way to configure the
ObjectMapper to utilize a particular shape by default? Using annotations on
the POJO's is currently not an option.
I'm using the latest Jackson (2.8.6).
