据说这个bug仅仅会在 Grails 1.0.4 中出现，有人建议直接使用 1.0.5 的预览版本，不过我看到 1.1 beta2 已经发布了，看来用不了再等多长的时间了。
修改文件 GRAILSAPP/plugins/fckeditor-0.8/grails-app/controllers/FckeditorController.groovy
在最后面，大概是 264 行附近开始，把如下一段：
def file = multiRequest.getFile(“NewFile”)
if (!file) {
errorNo = Fckeditor.ERROR_CUSTOM
errorMsg = “INVALID FILE”
}
else {
errorNo = Fckeditor.ERROR_NOERROR
newName = file.originalFilename
def f = splitFilename( newName )
if (isAllowed(f.ext, type)) {
def fileToSave = new File( finalDir, newName )
if ( !overwrite ) {
def idx = 1
while ( fileToSave.exists() ) {
errorNo = Fckeditor.ERROR_FILE_RENAMED
newName = “${f.name}(${idx}).${f.ext}”
fileToSave = new File( finalDir, newName )
idx++
}
}
file.transferTo( fileToSave )
}
else {
errorNo = Fckeditor.ERROR_INVALID_FILE_TYPE
errorMsg = “INVALID FILE TYPE”
}
}
替换为：
def file
if (ServletFileUpload.isMultipartContent(request)) {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List /* FileItem */ items = upload.parseRequest(request);
file = items.find {
!it.isFormField() && ‘NewFile’ == it.fieldName
}
}
if(file) {
errorNo = Fckeditor.ERROR_NOERROR
newName = String.valueOf(System.currentTimeMillis())+’.’+FilenameUtils.getExtension(file.name)
def f = splitFilename( newName )
if (isAllowed(f.ext, type)) {
def fileToSave = new File( finalDir, newName )
if ( !overwrite ) {
def idx = 1
while ( fileToSave.exists() ) {
errorNo = Fckeditor.ERROR_FILE_RENAMED
newName = “${f.name}(${idx}).${f.ext}”
fileToSave = new File( finalDir, newName )
idx++
}
}
file.write( fileToSave )
}
else {
errorNo = Fckeditor.ERROR_INVALID_FILE_TYPE
errorMsg = “INVALID FILE TYPE”
}
} else {
errorNo = Fckeditor.ERROR_CUSTOM
errorMsg = “INVALID FILE”
}
