어떻게이 문제를 해결하는 : 내가 스택 트레이스 다음을 참조하십시오 내 코드를 실행하면

@Converter 
public class MultiPartFileToFileConvertor { 
    @Converter 
    public static File toFile(MultipartFile multipartFile) throws IOException { 
     File convFile = new File(multipartFile.getOriginalFilename()); 
     multipartFile.transferTo(convFile); 
     return convFile; 
    } 
}

그리고 또한 내가하려고 컨버터를 등록?

그리고 파일 형식으로 변환하지 않으셨습니까? 그냥 그대로 보내어 구원받는 것입니까? –

sendBody를 호출하기 전에 파일을 작성하여 보내시겠습니까? – gstackoverflow

나는 from : ("seda : rest_upload") .convertBodyTo (File.class) .to ("file : // rest_files"); from ("seda : rest_upload") .to ("file : // rest_files"); –

TypeConverter라는 서비스 검색 파일을 META-INF 디렉토리에 추가해야합니다.

src\main\resources\META-INF\services\org\apache\camel\TypeConverter

이 파일은 @Converter 클래스의 완전한 이름이 포함되어 있습니다.

예컨대

mypackage.MultiPartFileToFileConvertor

또한 Github에서 https://github.com/camelinaction/camelinaction2/tree/b6a43abf9e0d4ec4e3753ebd735bb3448f98194b/chapter3/converter 액션 카멜 2에서 예를 참조.

또한 제 3.6 장에서는 사용자 지정 변환기의 검색과 로딩을 자세히 설명합니다.

귀하의 의견을 이해하지 못했습니다. 리소스에 파일을 추가 했습니까? – ltsallas
