Korean character encoding/decoding issue

Open pjh2259 opened this issue 4 months ago • 9 comments

My system's using Spring Boot embedded Undertow.

AS-IS

  • boot 2.6.6
  • MultipartResolver : org.springframework.web.multipart.commons.CommonsMultipartResolver
  • java 8

TO-BE

  • boot 3.4.4
  • MultipartResolver : org.springframework.web.multipart.support.StandardServletMultipartResolver
  • java 17

In a changed environment, Unicode strings are displayed abnormally intermittently.

We are receiving and processing data in multipart/form-data format as @RequestParam. Previously, it was available normally, but in changed environments, the data sometimes appears abnormal.

Can you tell me what is causing this phenomenon and what to do about it?
