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


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 ?


Solution

  • 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());
