在使用SwaggerBootstrapUi的朋友经常询问的一个问题,为什么上传参数file对象不显示file文本域,而是普通文本,如下图：
因为Springfox-Swagger针对不同的版本,某些版本也会出现此问题,为一劳永逸,SwaggerBootstrapUi特别指定需要强指定dataType类型为MultipartFile
代码示例(UploadController.java)：
@ApiOperation(value = "文件素材上传接口")
@ApiImplicitParams({@ApiImplicitParam(name = "file[]", value = "文件流对象,接收数组格式", required = true,dataType = "MultipartFile",allowMultiple = true),
@ApiImplicitParam(name = "title", value = "title", required = true)}
)
@RequestMapping(value="/uploadMaterial",method = RequestMethod.POST)
@ResponseBody
public RestMessage uploadMaterial(@RequestParam(value="file[]",required = true) MultipartFile[] files,@RequestParam(value = "title") String title, HttpServletRequest request) throws IOException {
//int mul=1*1024*1024;
String realPath=request.getSession().getServletContext().getRealPath("/upload");
File realFile=new File(realPath);
if (!realFile.exists()){
realFile.mkdirs();
}
List<Map> uploadFiles= Lists.newArrayList();
System.out.println("进入图片上传接口:"+files.length +"张");
for (MultipartFile file : files) {
File targetFile=new File(realFile,file.getOriginalFilename());
FileOutputStream fileOutputStream=null;
InputStream ins=null;
try{
fileOutputStream=new FileOutputStream(targetFile);
int i=-1;
byte[] bytes=new byte[1024*1024];
ins=file.getInputStream();
while ((i=ins.read(bytes))!=-1){
fileOutputStream.write(bytes,0,i);
}
}catch (IOException e){
}finally {
closeQuilty(ins);
closeQuilty(fileOutputStream);
}
Map fileInfo= Maps.newHashMap();
fileInfo.put("id", UUID.randomUUID().toString());
fileInfo.put("url",targetFile.getPath());
fileInfo.put("original_name",targetFile.getName());
uploadFiles.add(fileInfo);
}
RestMessage rm=new RestMessage();
rm.setData(uploadFiles);
return rm;
}
关于多文件上传，设置allowMultiple=true即可,在UI界面端,按住Ctrl键即可多选文件.
