如何通过 RESTEasy 发送文件列表 java

Question

我们如何通过 RESTEasy java 客户端发送文件列表？ Spring REST 是：

@PostMapping()
public ResponseEntity<?> send(@RequestPart(value = "message") String message, @RequestPart(value = "attachment", required = false) List<MultipartFile> attachments)

Postman中是在form-data中一键指定多个文件"attachment"，但是MultipartFormDataOutput里面有Map，所以只记住最后添加的文件

我已经使用 org.apache.http.entity.mime.MultipartEntityBuilder 解决了这个问题：

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("message", messageStr, ContentType.TEXT_PLAIN.withCharset(UTF_8));
for (File file: files) {
    builder.addBinaryBody(
            "attachment",
            new FileInputStream(file),
            ContentType.APPLICATION_OCTET_STREAM,
            file.getName()
    );
}
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost uploadFile = new HttpPost(url);
uploadFile.setEntity(builder.build());
CloseableHttpResponse response = httpClient.execute(uploadFile);
