예기치 않은 토큰 (START_OBJECT), 예상 VALUE_STRING : 필요 JSON 문자열 (java.lang.Object 상위의 하위 유형에 대한) 유형 ID를 포함합니다

난 이미 아래에 몇 가지 링크를 통해 갔다, 그러나 그것은 내 문제가 해결되지 않았다

내 프로젝트에서 우리는 15 개 일괄 처리 작업을했습니다. 나는 15 가지 마이크로 서비스로 15 개 배치 작업을 전환하고있다. 이를 위해 나는 엔티티 클래스, JPA 저장소 계층과 서비스 계층을 가지고 하나 개의 봄 부팅 모듈을 만들었습니다. 나는 각각의 마이크로 서비스 (일괄 작업)로 가져옵니다 그 항아리, 그 배치 작업이 잘 작동해야하므로.

XML 기반의 접근 방식 - 나는 봄 부팅 + 스프링 배치를 사용하고 있습니다.

그래서 내가 XML 기반의 일괄 작업 구성을 쓴 또 다른 봄 부트 모듈에 XJPA 모듈 준비 및 가져 왔습니다.

암호:

@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

해결법

1. ==============================

   1.나는 선을 제거하면

   나는 선을 제거하면

   objectMapper.enableDefaultTyping();
   

   그것은 내 문제를 해결했다. 그러나이 라인이 필요한 다른 경우에, 조심
