“如何更正集合”；“边界”；进入java.net.http.HttpRequest头 我试图使用JDK11中的HttpClient和HttpRequest向服务器发送一个多部分文件： 服务器端发生以下错误：

错误17072---[nio-8081-exec-2] o、 a.c.c.c.[/].[dispatcherServlet]：的Servlet.service（） 路径为[]的上下文中的servlet[dispatcherServlet]引发异常 [请求处理失败；嵌套异常为 org.springframework.web.multipart.MultipartException:未能分析 多部分servlet请求；嵌套异常为java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: 请求被拒绝，因为找不到具有的多部分边界] 根本原因

如何正确设置标题以避免此错误？

public static int sendMultipartFile(String uri, Path filePath) {
    HttpClient httpClient =`enter code here` HttpClient.newBuilder()
            .version(HttpClient.Version.HTTP_2)
            .build();

    HttpRequest request = HttpRequest.newBuilder()
            .uri(URI.create(uri))
            .POST(HttpRequest.BodyPublishers.ofFile(filePath))
            .header("Content-Type", "multipart/form-data")
            .setHeader("Boundary", "gc0p4Jq0M2Yt08jU534c0p")
            .build();
    HttpResponse<String> response = httpClient.send(request, HttpResponse.BodyHandlers.ofString());
    return response.statusCode();
}

@PostMapping("/api/logs/throw")
public void handleFileUpload(@RequestParam("logs.7z") MultipartFile file) {
    Path path = Paths.get("/home/terminal_logs/");
    storageService.store(file, path);
}
