Answer 1

For Jackson 2.10 and above,

parent pom.xml

  
    com.fasterxml.jackson
    jackson-bom
    2.10.3
    pom
    import
  

module pom.xml

    com.fasterxml.jackson.datatype
    jackson-datatype-jsr310

JsonMapper creation, possibly in your @Configuration class

@Bean
public JsonMapper jsonMapper() {
    return JsonMapper.builder()
        .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
        .addModule(new JavaTimeModule())
        .build();
}
