Deserialising OffsetDateTime with Springboot webclient - spring-boot

Question

I am facing issue related to OffsetDateTimeStamp while writing test case for my webservice. When I test from browser, it's gives right response but while writing test case it's not showing offset and because of that it's failing.
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class TestControllerTest {
#LocalServerPort
private int port;
private WebClient client;
#Test
public void test() {
Person person = new Person();
person.setId(1);
person.setBirthDate(OffsetDateTime.now());
person.setMobile(9090909090L);
person.setName("Tempo");
client = WebClient.create("http://localhost:"+port);
Person response = client.post().uri("/test1")
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON)
.body(BodyInserters.fromValue(person))
.retrieve()
.bodyToMono(Person.class)
.block();
Assertions.assertEquals(person.getBirthDate(), response.getBirthDate());
}
}
Controller Code
#RestController
public class TestController {
#PostMapping("/test1")
public Mono<Person> test1(#RequestBody Person person) {
System.out.println(person.getBirthDate());
return Mono.just(person);
}
}
Mail Application code
#SpringBootApplication
public class TestAppApplication {
public static void main(String[] args) {
SpringApplication.run(TestAppApplication.class, args);
}
#Bean
public Module javaTimeModule() {
return new JavaTimeModule();
}
#Bean
public Jackson2ObjectMapperBuilderCustomizer jacksonObjectMapperCustomization() {
return jacksonObjectMapperBuilder -> jacksonObjectMapperBuilder.timeZone(TimeZone.getDefault());
}
}
Person.java
public class Person {
private int id;
private String name;
private long mobile;
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
private OffsetDateTime birthDate;
public Person() {}
}
application.properties
spring.jackson.serialization.write-dates-as-timestamps=false
spring.jackson.deserialization.adjust-dates-to-context-time-zone=false
spring.jackson.serialization.write-dates-with-zone-id=true
output of test case

Answer 1

How is your property birthDate defined in your Person entity class? You need to define the format there. You can do it like this:
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZ")
private OffsetDateTime birthDate;
...
public OffsetDateTime getBirthDate() {
return birthDate;
}
