Apache POI를 사용하여 .xlsm 파일을 다시 작성하는 방법은 무엇입니까?

Question

이 코드를 사용하여 Apache POI를 사용하여 xlsm 파일을 다시 작성합니다. 내가 결과 세트에서 Sheet1에 대한 데이터를 다시 작성 해야이 코드는 템플릿 xlsm 파일의 복사본을 만들고 모든 처리 않습니다.

하지만 생성 된 XLSM 파일을 열 때 그것은 나에게이 메시지를 보여줍니다

우리는 'FileName.xlsm'의 일부 내용에 문제가 있음을 발견했다. 우리가 최대한 많이 복구하기를 원합니까? 이 통합 문서의 원본을 신뢰하는 경우 예를 클릭하십시오.

여기 내 코드입니다. 제발 내가해야 할 일을 제안하십시오. 완료
