cannot serialize/de-serialize java.time.Instant field-CodePudding

I have 2 spring boot based microservices which interact through events. Producer microservice sends an event which is a POJO to RabbitMQ queue. Consumer microservice listens to the queue. The POJO has 2 java.time.Instant fields which spoils the serialization/de-serialization process. For now I have commented out these fields & it is working. I have tried by declaring a Jackson2JsonMessageConverter bean:

@Bean
public Jackson2JsonMessageConverter converter() {
    ObjectMapper objectMapper = new ObjectMapper()
            .findAndRegisterModules().disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
    return new Jackson2JsonMessageConverter(objectMapper);
}

Here is the stack trace which states that the problem is with Instant fields.

So what to do? Should I go for LocalDateTime in place of Instant?

CodePudding user response：

For timestamp, I have used SQL timestamp, which perfectly serialize and deserialize the object without touching the object mapper configuration

import java.sql.Timestamp;

@Data
public class Test{

  private Timestamp time;
  
}

CodePudding user response：

You will need to add the following dependency:

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

And then you need to customize your ObjectMapper as follows:

@Configuration
public class JacksonConfig {

    @Bean
    @Primary
    public ObjectMapper objectMapper() {
        JavaTimeModule module = new JavaTimeModule();
        return new ObjectMapper().registerModule(module);
    }
}
