Spring boot 2.6.4 all my variables of type date and localtime gives only number without format

Question

My spring boot project has a problem, I updated from version 2.5.1 to 2.6.4 and now all my variables of type date and localtime are given number without format examples :

date = "2022-03-04" in JSON are "1646352000000"

and my localtime are like this :

localtime = "09:00:00" in JSON is "9"

any suggestions on how to fix it ?

Answer 1

You should configure Jackson in order to avoid serialization of Java dates in timestamp.

You should add

dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
<version>2.9.5</version>

and configure it like this

ObjectMapper mapper = new ObjectMapper(); mapper.registerModule(new JavaTimeModule());
