ajax(비동기)로 image파일을 저장하고 리턴값으로 membervo를 해주려고 했는데 그 과정에서 에러가 났습니다. 해당 에러는 하단의 것처럼 FileNotFoundException이 발생한 것이었습니다.

에러를 자세히 살펴보면 jackson.databind 에러가 발생함을 알 수 있습니다.
해당 에러가 나는 이유는 Spring에서 @restcontroller를 붙여주게되면 자동으로 해당 컨트롤러들에게 @responseBody가 먹히게 됩니다.
따라서 return 데이터들을 json타입으로 마샬링을 합니다.
위에서 언급했듯이 ajax로 image를 memberVO에 담아 webResource Path로 저장한 후 db에도 값을 올린 후에 return으로 memberVO를 받아왔기 때문에 최초 업로드 시에 memberVO에 담긴 image파일을 json으로 마샬링하려고 했기에 발생한 에러입니다.
그런데 byte는 json으로 마샬링이 불가능 합니다.
해결 방법은 두가지가 있습니다.
- return값을 용도에 따라 나눕니다.
- 현재는 보시는 바와 같이 ajax로 넘긴 memberVO를 그대로 다시 return값으로 넘기는데 그렇게 하지 말고
- 꼭 필요한 데이터만 return으로 넘깁니다.(set을 사용해서 비운 후에 다시 보내도 될 듯 합니다.)
- @JsonIgnore를 사용합니다.
- json 마샬링을 원하지 않는 데이터의 경우 어노테이션을 사용해서 제외시켜 줍니다.
- 현재는 jsonIgnore를 사용하고 있지만 두가지 방법 모두 적절하게 섞어서 사용하는 것이 좋을 듯 합니다.
