Changing JsonPathProvider to Jackson breaks the JsonPathLinkDiscoverer #1980
Description
Changing JsonPath provider to JacksonProvider breaks the createLinksFrom in JsonPathLinkDiscoverer
By setting the Configuration of the JsonPath to JacksonJsonProvider - the createLinksFrom breaks it's usage (as it relies only on JsonSmartJsonPRovider)
Configuration.setDefaults(new Configuration.Defaults() {
private final JsonProvider jsonProvider = new JacksonJsonProvider();
private final MappingProvider mappingProvider = new JacksonMappingProvider();
@Override
public JsonProvider jsonProvider() {
return jsonProvider;
}
@Override
public MappingProvider mappingProvider() {
return mappingProvider;
}
@Override
public Set<Option> options() {
return EnumSet.noneOf(Option.class);
}
});
breaks almost all tests in the HalLinkDiscovererUnitTest.
However adding:
if (List.class.isInstance(parseResult)) {
List<?> list = (List<?>) parseResult;
return list.stream()
.flatMap(it -> List.class.isInstance(it) ? ((List<?>) it).stream() : Stream.of(it))
.map(it -> extractLink(it, rel))
.collect(Links.collector());
}
in the JsonPathLinkDiscoverer file fixes those Tests (however still few other tests are broken).
I think the implementation in Spring shouldn't so closely rely on using net.minidev.json packages
