私はspring-bootマイクロサービスにアップロードしようとしているファイルがあります。 FormDataのjavascriptオブジェクトを使用してファイルを投稿するためにjQueryを使用しています。私のFormDataのファイルをRequestParamファイルに一致させることができなかったため、Springブートは私のコントローラのエンドポイントを呼び出さない。jQueryとSpring-Bootファイルのアップロードが原因で「要求された要求部分 'ファイル'が存在しません」
はJavaScript：ここ
var name = "TEST";
var kml = '<kml><Document><Placemark id="' + name + '"><Point><coordinates>-69.83701518,47.817278750000014</coordinates></Point></Placemark></Document></kml>';
// upload the kml file to the server
var data = new FormData();
data.append('file', kml);
$.ajax({
method: "POST",
url: "http://localhost:9096/upload/" + name,
data: data,
cache: false,
contentType: false,
processData: false,
success: function(data){
console.log("success", name, data);
}
});
は私のコントローラのコードです：ここで
@RestController
public class MicroServiceController {
private Logger logger = LoggerFactory.getLogger(MicroServiceController.class);
@RequestMapping(value="/upload/{name}", method = { RequestMethod.POST })
public ResponseEntity<?> uploadKML(@PathVariable String name, @RequestParam("file") MultipartFile file) throws IOException {
logger.debug("Upload: {}", name);
return new ResponseEntity<Boolean>(true, HttpStatus.OK);
}
}
は例外です：

、私は「ファイル」に設定されたファイルの名前を持っているように見える、と私はまたMicroserviceで「ファイル」を探しています...しかし、スプリングブート側に接続するようには見えません。私はすべてがインターネット上の例と問題のように見えるので混乱していますが、私はまだ例外を取得します。
次に試してみるべきことや、私がうんざりしたところには何かアドバイスがあります。
が、私は彼らのフォーラムをキャンセルするためのスプリングブートコミュニティで非常に失望して、stackoverflowの質問に答えるないんだけど、それがお役に立てば幸いです。彼らのウェブサイトのほとんどの質問ページには0の回答があります。 – Kieveli
この問題を抱えている人は、フォームデータを使用しないでkmlを本体に入れ、 "@RequestParam MultipartFile file"から "@RequestBody String kml"に変更して問題を回避しようとしています。私のkmlが大きすぎると私はポボチャになります。 – Kieveli
MultipartFileをMultipartFile []に変更すると呼び出しが成功しますが、配列は空です。 – Kieveli
