使用表单上传文件的时候报错：
1 2 3 4 5 | HTTP Status 500 - Failed to convert value of type 'java.lang.String' to required type 'org.springframework.web.multipart.MultipartFile'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [org.springframework.web.multipart.MultipartFile]: no matching editors or conversion strategy found org.springframework.beans.ConversionNotSupportedException: Failed to convert value of type 'Java.lang.String' to required type 'org.springframework.web.multipart.commons.CommonsMultipartFile' |
是因为没有设置在multipart/form-data 模式 springMVC 无法进行有效的转换
完整的设置为：
1 | <form method="post" enctype='multipart/form-data' action="<%=path%>/mng/news/doChangeNews.html"> |
即可解决
