필드 오류 '필드 오브젝트 대상'의 거부 된 값 []; 코드 [typeMismatch.target., TypeMismatch 예외., typeMismatch.java.util.Date, TypeMismatch 예외]

내가 만든 : https://jira.spring.io/browse/BATCH-2778

나는 스프링 배치 + 레디 스 (봄 데이터 레디 스) 예를 개발하고있다. 이 예제에서는 student.csv 파일을 읽고 레디 스 DB에 모든 데이터를 저장하고있다. 나는 날짜로 사용 생년월일 (DateOfBirth)에 원하고 나는 확실히 내가 레디 스에서 값을 저장 날짜에 일부 날짜 로직 변환을 할 필요가 있다고 생각합니다.

내 분석에 따라, 내가 전혀 JSON을 처리하고 있지 않다 때문에 나는, @JsonFormat (모양 = JsonFormat.Shape.STRING, 패턴 = "YYYY-MM-DD")를 사용할 수 습관처럼 보인다. 내가 바이트 [] 등으로 날짜와 날짜에 바이트를 [] 변환 등의 변환기를 이용해야한다고 생각

가리키고 나는이 옵션을 시도했지만 작동하지 않습니다. 어떤 빠른 도움말?

참고 : 나는 문자열 값으로 생년월일 (DateOfBirth)을 저장하지 않습니다.

해결법

==============================
1.문제는 JSON 관련이 없습니다, 스택 트레이스에 따라 문제가 BeanWrapperFieldSetMapper가 java.util.Date에 1988년 5월 12일 12시 34분 45초를 변환하는 방법을 알고하지 않습니다. 이 같은 사용자 정의 날짜 편집기로 구성해야합니다 :

문제는 JSON 관련이 없습니다, 스택 트레이스에 따라 문제가 BeanWrapperFieldSetMapper가 java.util.Date에 1988년 5월 12일 12시 34분 45초를 변환하는 방법을 알고하지 않습니다. 이 같은 사용자 정의 날짜 편집기로 구성해야합니다 :
```
CustomDateEditor customDateEditor = new CustomDateEditor(/* your DateFormat here */);
HashMap<Class, PropertyEditor> customEditors = new HashMap<>();
customEditors.put(Date.class, customDateEditor);
fieldSetMapper.setCustomEditors(customEditors);
```
CustomDateEditor가 스프링 프레임 워크에서입니다 : org.springframework.beans.propertyeditors.CustomDateEditor.

도움이 되었기를 바랍니다.

또는

나는 다음과 같은 것을 사용했다. 레디 스처럼 보인다는 자바 7 날짜 API 제대로 작동하지 않지만, 자바 8 API와 함께 잘 작동합니다. 그러나 동일한에 대한 기본 지원에는 밖에 없다.

public class StudentFieldSetMapper implements FieldSetMapper<Student>{

    @Override
    public Student mapFieldSet(FieldSet fieldSet) throws BindException {

        return Student.builder()
                .id(fieldSet.readString("id"))
                .firstName(fieldSet.readString("firstName"))
                .lastName(fieldSet.readString("lastName"))
                .dateOfBirth(fieldSet.readDate("dateOfBirth", "dd-MM-yyyy HH:mm:ss")).build();
    }
}
