Adding springfox to spring boot project alters DateTime serialization

After adding springfox to my spring boot application, I have noticed that the serialization of http responses containing java.time.LocalDateTime have changed. Here’s an export of a before an after of a snippet of JSON from one of my POJOs that is returned as part of an HTTP response to a call to a REST controller method:

"jobStateLastUpdated":"2018-11-06T10:29:57.21", to "jobStateLastUpdated":[2018,11,6,10,23,49,566000000],

Can I control this behavior? Why is springfox altering the serialization in this manner? I confirmed that the introduction of the Docket class impacted the serialization.

I’m using the following dependencies in my pom.xml file

		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger2</artifactId>
			<version>2.9.2</version>
			<scope>compile</scope>
		</dependency>
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger-ui</artifactId>
			<version>2.9.2</version>
			<scope>compile</scope>

I was able to reproduce this issue with a simpler project. I uploaded the source code here – its a modified set of code from a time/date serialization example project with spring boot.

https://github.com/rgupta4-akoya/sf-2764 (look at the HEAD and previous commit).

commit: bc8de0c (before enabling the swagger / springfox config) curl http://localhost:8080/clock {"localDate":"01::01::2016","localTime":"10:24","localDateTime":"2018-11-15T04:18:34.419Z"}

commit 48a16eb (after enabling the swagger / springfox config) curl http://localhost:8080/clock {"localDate":[2016,1,1],"localTime":[10,24],"localDateTime":1542255735.144000000}

@rgupta4-akoya this is probably needed because you weren’t using the same object mapper for the serialization as you were for inferring the swagger spec
