InvalidDefinitionException with jackson-datatype-jsr310 version 2.12.3

Question

I'm having an issue with the jackson jsr310 datatype using version > 2.12.0, while this works perfectly with version 2.11.4.

This is my POJO:

import java.time.OffsetDateTime;

public class Pojo {
    OffsetDateTime aDateTime;

    public OffsetDateTime getaDateTime() {
        return aDateTime;
    }

    public void setaDateTime(OffsetDateTime aDateTime) {
        this.aDateTime = aDateTime;
    }
}

The spring application:

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import java.time.Instant;
import java.time.ZoneOffset;

@SpringBootApplication
public class OffsetTimeTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(OffsetTimeTestApplication.class, args);
    }

    public OffsetTimeTestApplication() {
        ObjectMapper mapper = new ObjectMapper();
        Pojo pojo = new Pojo();
        pojo.setaDateTime(Instant.now().atOffset(ZoneOffset.UTC));
        try {
            mapper.writeValueAsString(pojo);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
    }

}

Relevant section from my build.gradle file:

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    implementation group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.12.3'
    implementation group: 'com.fasterxml.jackson.core', name: 'jackson-annotations', version: '2.12.3'
    implementation group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.12.3'
    runtimeOnly group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310', version: '2.12.3'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

The exception I get is:

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Java 8 date/time type `java.time.OffsetDateTime` not supported by default: add Module "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" to enable handling (through reference chain: com.enervalis.offsettimetest.Pojo["aDateTime"])

Changing the version in the build file from 2.12.3 to 2.11.4 the code runs without error.

Is there anything missing?

This works perfectly well with version 2.11.4 and lower.

Answer 1

This is resolved.

Apparently, by adding the dependency, but not registering the JavaTimeModule, the OffsetDateTime gets serialized as a POJO in older versions. In the > 2.11.4 version th eException is thrown.

The JavaTimeModule must be added to the ObjectMapper:

        ObjectMapper mapper = JsonMapper.builder()
                .addModule(new JavaTimeModule())
                .build();
