Неожиданный токен (START_OBJECT), ожидаемый VALUE_STRING: требуется строка JSON, содержащая идентификатор типа (для подтипа java.lang.Object)

Я уже просмотрел несколько ссылок ниже, но это не решило мою проблему:

Java Jackson: десериализация сложной полиморфной объектной модели: JsonMappingException: неожиданный токен (START_OBJECT), ожидаемый VALUE_STRING
Java Jackson - неожиданный токен (START_ARRAY), ожидается VALUE_STRING

В моем проекте 15 пакетных заданий. Я конвертирую 15 пакетных заданий в 15 различных микросервисов. Для этого я создал один модуль Spring Boot, который имеет классы Entity, уровень репозитория JPA и уровень обслуживания. Эту банку я буду импортировать в каждую микросервису (пакетное задание), чтобы пакетное задание работало нормально.

Я использую Spring boot + Spring Batch - подход на основе XML.

Итак, у меня есть модуль XJPA, готовый и импортированный в другой модуль Spring Boot, где я написал конфигурации пакетных заданий на основе XML.

код:

@Component
@EnableBatchProcessing
@ImportResource("classpath:jobs/ABC_context.xml")
public class XXXLauncher {

    @Autowired
    private JobLauncher jobLauncher;

    @Autowired
    private Job job;

    public void executeXXXXXXXXXXJob() {

        try {
            // @formatter:off
            JobParameters jobParameters = new JobParametersBuilder()
                    .addString("runMode", "XXXX")
                    .addDate("date", new Date())
                    .addLong("time", System.currentTimeMillis()).toJobParameters();
            // @formatter:on

            jobLauncher.run(job, jobParameters);
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
}

ABC_job.xml

<batch:job id = "x">
    <batch:step id = "y">
        <batch:tasklet ref = "xyzTasklet" />
    </batch:step>
</batch:job>

<bean id = "stepScope" class = "org.springframework.batch.core.scope.StepScope">
    <property name = "autoProxy" value = "true"/>
</bean>

<bean id = "xyzTasklet" class = "com.XXXX.tasklet.xyzTasklet" scope = "step">
    <property name = "runType" value = "#{jobParameters['runMode']}" />
    <property name = "executionContext" value = "#{stepExecution.jobExecution.executionContext}" />
</bean>
