我有一个可能要解析的大文件，作为MultipartFormDataInput的一部分传递给REST服务。由于解析可能需要很长时间，因此我想在后台线程中进行解析：
@Resource
private ManagedExecutorService executorService;
@POST
@Path("file")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public void upload(MultipartFormDataInput input) {
executorService.execute(() -> {
for (InputPart inputPart : input.getFormDataMap().get("file")) {
try {
InputStream inputStream = inputPart.getBody(InputStream.class, null);
CSVReader csvReader = new CSVReader(new InputStreamReader(inputStream, "UTF-8"));
// further processing
} catch (Exception e) {
logger.error("Something went wrong", e);
}
}
});
}
不幸的是，getBody引发以下错误：
org.jboss.resteasy.spi.LoggableFailure：RESTEASY003880：无法找到以下类型的上下文数据：javax.ws.rs.ext.Providers
有机会我可以在其他线程中提取身体吗？
