는하지만이 오류를 받고 있어요. 클라이언트 측에서

이 응답입니다 :

ParseError at [row,col]:[1,11347] 

그러나이보고 그것의 오류입니다 발견하기가 매우 어렵습니다. 어쨌든이 오류를 해결할 수 있습니까?

Answer 1

예외에서 알 수 있듯이, 쓰려고하는 객체의 일부 문자열 (문자 데이터 값)에 null 문자 (유니 코드 0)가 포함되어 있습니다. 손상된 문자열 값을 찾아서 수정하는 것 이외에도 Woodstox가 잘못된 문자 값을 변경하도록하여이 문제를 해결할 수도 있습니다. How to alleviate the infamous "Xml Invalid Character" problem with Woodstox을 참조하십시오.
