This commit improves JsonPathExpectationsHelper to allow a custom json path configuration to be defined. The primary objective of a custom configuration is to specify a custom mapper that can deserialize complex object structure. As part of this commit, it is now possible to invoke a Matcher against a type that holds generic information, using a regular ParameterizedTypeReference. Given that the existing constructor takes a vararg of Object, this commit also deprecates this constructor in favor of formatting the expression String upfront. Closes spring-projectsgh-31651

JSONPath supports using a
Configurationto customize its behavior, or to pass aJsonProviderthat in turn enables parsing to higher level objects.JsonPathExpectationsHelpermanages JSONPath internally without any option to change this, and effectively usesConfiguration.defaultConfiguration()that supports parsing to basic types only.We should open up
JsonPathExpectationsHelperto make it possible to pass or customize theConfigurationto use, and that would enable decoding to higher level objects. The helper does have a method to read to a targetClassbut it won't work for anything more than basic types, and we add another that takesParameterizedTypeReference.This will not fully address #27486 and #31423 since MockMvc there is no good way to re-use a custom
Configurationin a static API. However, it will enableWebTestClientto transparently pass aConfigurationtoJsonPathExpecationsHelper. It will also make it possible for MockMvc users to create a customResultMatcherinstance that delegates toJsonPathExpectationsHelper. We can separately explore some such built-in option for MockMvc.The text was updated successfully, but these errors were encountered:
