错误提示:
org.springframework.validation.BeanPropertyBindingResult: 1 errors
Field error in object ‘commentDto’ on field baseFile’: rejected value []; codes [typeMismatch.commentDto.baseFile,typeMismatch.baseFile,typeMismatch.[Lorg.springframework.web.multipart.MultipartFile;,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [commentDto.baseFile,baseFile]; arguments []; default message [baseFile]]; default message [Failed to convert property value of type ‘java.lang.String’ to required type ‘org.springframework.web.multipart.MultipartFile[]’ for property ‘baseFile’; nested exception is java.lang.IllegalStateException: Cannot convert value of type ‘java.lang.String’ to required type ‘org.springframework.web.multipart.MultipartFile’ for property ‘baseFile[0]’: no matching editors or conversion strategy found]
解决方式:
MultipartFile.fromFileSync(
data["image"],
filename: suffix,
contentType: MediaType('application', 'octet-stream'),//这行是新增的
)
文章描述了一个在处理SpringMVC表单提交时遇到的错误,涉及MultipartFile类型的转换失败。解决方案是在代码中使用MultipartFile.fromFileSync方法,并指定contentType来确保文件类型的正确转换。
