rest - com.fasterxml.jackson.databind.JsonMappingException: Can not instantiate value of type [simple type, class java.time.LocalDateTime] from String -
i have java8 localdatetime in jax-rs rest apis. webapp deployed in wildfly10. when make post call(which includes localdatetime parameter) following exception;

any help?
the first question linked involves conversion of @xxxparam annotations. paramconverterprovider for. different (de)serailization process entity body (de)serialization.
for entity (de)serialization, messagebodyreader/messagebodywriters used. jackson provides 1 such implementation, in jacksonjsonprovider/jacksonjaxbjsonprovider, using, whether know or not. configuration localdatatime needs somehow configured provider.
the way configure jackson support localdatetime serialization, through it's objectmapper. can create custom json(de)serializer, mentioned in post (option two), or can use jsr310module (that has custom json(de)serializer localdatetime), mentioned in this post.
to configure jacksonjsonprovider/jacksonjaxbjsonprovider use configured objectmapper, can use contextresolver, mentioned in both of previous links, or can construct jacksonjsonprovider objectmapper, , register provider
objectmapper mapper = new objectmapper(); mapper..configurmoduleorserializer jacksonjsonprovider provider = new jacksonjsonprovider(mapper); registerprovier(provider) personally go contextresolver, mentioned in links. difference above code, objectmapper provided provider explicitly, while contextresolver, during runtime, provider search jax-rs registry contextresolver of type objectmapper, , obtain way.
