Java Spring WebFlux 多部分文件上传

Question

I am trying to make simple post-request with a image. But it is not working.

My html post form data (multipart/form-data):

book[0].cover = 123.jpg;  <--- upload file image
book[0].title = "title 123";
book[0].author = "123"

book[1].cover = abc.jpg;
book[1].title = "title abc";
book[1].author = "abc"

restapi image

curl -X POST http://127.0.0.1/book/postCreate \
    -H 'Content-Type: multipart/form-data' \
    -d 'book%5B0%5D.file=[$file.30378169-jpg]&book%5B0%5D.title=title%20123&book%5B0%5D.author=author%20123&book%5B1%5D.file=[$file.30378190-jpg]&book%5B1%5D.title=title%20abc&book%5B0%5D.author=author%20abc'

My controller method is setup as follows:

public Mono<ServerResponse> postCreate(ServerRequest request) {
    Flux<Book> book = request.bodyToFlux(Book.class);  // error
    // How can I get the data of the form ?
}

class Book {
    FilePart cover;
    String title;
    String author;
}

How can I get the data of the form?

Im not the best at java, but when I go into visual studio code and enter this in, it gives me a couple of errors.

book[0].cover = 123.jpg;  <--- uplaod file image
book[0].title = "title 123";
book[0].author = "123"

book[1].cover = abc.jpg;
book[1].title = "title abc";
book[1].author = "abc"

first of all, upload is spelt wrong, that's probably why. When I click on the word "file" in visual studio code it will just change to "File" not "file". I think capitalization is the problem here but I'm not fluent in java.

Like I said, I'm not fluent in java because I code python and sometimes JavaScript but I have never seen a error like this.
