Issue to deserialize string to java util TimeZone

[harishajdarevic]

I'm having issues making Jackson object mapper deserialize JSON into an object that has a TimeZone field.

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of com.fasterxml.jackson.module.mrbean.generated.java.util.TimeZone(although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('America/New_York')

Any idea is more than welcome.

Thanks

And this is using the Java 8 module? Reviewing the unit tests might give some idea, and beyond that if you have a code sample showing how the error is arrived at, that would be helpful.

Hi @kupci

Here are is the list of registered modules that is return by objectMapper.findAndRegisterModules()

0 = "com.fasterxml.jackson.datatype.jdk8.Jdk8Module"
1 = "com.fasterxml.jackson.datatype.jsr310.JavaTimeModule"
2 = "com.fasterxml.jackson.datatype.joda.JodaModule"
3 = "com.fasterxml.jackson.module.kotlin.KotlinModule"
4 = "com.hidden.hidden.init.ObjectMapperFactory$1"
5 = "com.fasterxml.jackson.module.mrbean.MrBeanModule"
6 = "com.fasterxml.jackson.module.jaxb.JaxbAnnotationModule"
7 = "com.fasterxml.jackson.datatype.jsr310.JSR310Module"
8 = "com.fasterxml.jackson.module.paramnames.ParameterNamesModule"
9 = "com.fasterxml.jackson.datatype.hibernate5.Hibernate5Module"

And sure that I've code here it is:

objectMapper.readValue(emailMember.getEmailJson(), EmailRequest.class)

where emailMember.getEmailJson() is

{"toAddresses":[{"memberId":1142783,"sponsorId":57947,"emailAddress":"QA5e633008-8d29-4a84-b3c6-fea0c5ef1ca9@QAautovp.com","firstName":"TestFirst8ef1acbc-d11f-4a66-b151-0efdad51c905","lastName":"TestLastbc171f54-50e2-43c7-9640-d5116cdad11c","timeZone":"America/New_York"}],"fromAddress":{"name":"qa-xxxx Pulse","email":"qa-no-reply@xxxx.com","nameWithEmail":"qa-xxxx Pulse <qa-no-reply@xxxx.com>"},"replyToAddress":{"name":"qa-xxxx Pulse","email":"qa-no-reply@xxxx.com","nameWithEmail":"qa-xxxx Pulse <qa-no-reply@xxxx.com>"},"emailId":"bcebda9c-ff7f-4874-a443-755c4549c187","substitutions":{"trackerChallengeEndDate":"Feb 08","whyItMattersSection":"Because it matters...","sponsorName":"paniniTestSponsor","daysToTrack":6,"chatEnabled":true,"tipsSection":"tips and advices...","targetDays":5,"trackerName":"Diabetes Tracker","contentPhotoUrl":"https://file.xxxx.com/api/file/j4pbqUsJTQKQvnDIGjqB","totalDays":5,"sponsorLogoUrl":"https://miro.medium.com/max/1200/1*HSrZUaWEY4psyxup9auZUw.jpeg","checkTheYesOMeterUrl":"https://aa.xxxx.com/?email=QA5e633008-8d29-4a84-b3c6-fea0c5ef1ca9%40QAautovp.com#/challenges/healthyhabits/34901","joinTheChallengeUrl":"https://aa.xxxx.com/?email=QA5e633008-8d29-4a84-b3c6-fea0c5ef1ca9%40QAautovp.com#/challenges/healthyhabits/34901","seventhDay":"Feb 08","trackerChallengeStartDate":"Feb 04"},"emailType":"PromotedTrackerChallengeInvitation","locale":"en_us","content":"","subject":"","data":"","sendDateTime":"2021-04-21T15:00:00","emailDeliveryType":"Promotional","resend":false,"batchId":"PromotedTrackerChallengeId-22013-sponsorId-57947-batch-2","emailRequestType":"MemberEmail"}

I found it.

I've to register a new instance of objectMapper without MrBean module. There is conflict with it that is culprit for above error.

[kupci]

There do seem to be some caveats mentioned on the Mr. Bean documentation that might explain this. Anyway, glad you found the conflict.

[cowtowncoder]

If there was an easy way to reproduce this, we could try to see if something could be done to prevent this specific issue.
In general it is a difficult problem -- MrBean does materialize interfaces, abstract classes, and cannot know what all modules might produce -- but at least I could verify that this can be problematic, and if so, can it be avoided by java8 module.

Or, actually, MrBean: I suspect it should never try to materialize anything under "java." or "javax.". And adding such setting (behind a config feature) seems simple enough.

[cowtowncoder]

I created an issue for Mr Bean; and fixed it -- java.util.TimeZone should work as expected in 2.12.4 / 2.13.0; 2.13.0 will by default prevent materialization of anything under java.* (unless we find some big issues with that exclusion).
