我实际上是在尝试扩展开源项目（逻辑文档）的REST API，以允许更新一项设置。
@Override
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces({ MediaType.TEXT_PLAIN, MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
@ApiOperation(value = "Uploads a document", notes = "Creates or updates an existing document, if used in update mode docId must be provided, when used in create mode folderId is required. Returns the ID of the created/updated document. <br/>Example: curl -u admin:admin -H ''Accept: application/json'' -X POST -F folderId=4 -F filename=newDoc.txt -F filedata=@newDoc.txt http://localhost:8080/services/rest/document/upload")
@ApiImplicitParams({
@ApiImplicitParam(name = "docId", value = "The ID of an existing document to update", required = false, dataType = "integer", paramType = "form"),
@ApiImplicitParam(name = "folderId", value = "Folder ID where to place the document", required = false, dataType = "string", paramType = "form"),
@ApiImplicitParam(name = "release", value = "Indicates whether to create or not a new major release of an updated document", required = false, dataType = "string", paramType = "form", allowableValues = "true, false"),
@ApiImplicitParam(name = "filename", value = "File name", required = true, dataType = "string", paramType = "form"),
@ApiImplicitParam(name = "language", value = "Language of the document (ISO 639-2)", required = false, dataType = "string", paramType = "form", defaultValue = "en"),
@ApiImplicitParam(name = "filedata", value = "File data", required = true, dataType = "file", paramType = "form") })
@ApiResponses(value = { @ApiResponse(code = 401, message = "Authentication failed"),
@ApiResponse(code = 500, message = "Generic error, see the response message") })
public Response upload(@ApiParam(hidden = true) List<Attachment> attachments) throws Exception {
String sid = validateSession();
try {
Long docId = null;
Long folderId = null;
boolean release = false;
String filename = null;
String language = null;
DataHandler datah = null;
for (Attachment att : attachments) {
Map<String, String> params = att.getContentDisposition().getParameters();
// log.debug("keys: {}", params.keySet());
// log.debug("name: {}", params.get("name"));
if ("docId".equals(params.get("name"))) {
docId = Long.parseLong(att.getObject(String.class));
} else if ("folderId".equals(params.get("name"))) {
folderId = Long.parseLong(att.getObject(String.class));
} else if ("release".equals(params.get("name"))) {
release = Boolean.parseBoolean(att.getObject(String.class));
} else if ("filename".equals(params.get("name"))) {
filename = att.getObject(String.class);
} else if ("language".equals(params.get("name"))) {
language = att.getObject(String.class);
} else if ("filedata".equals(params.get("name"))) {
datah = att.getDataHandler();
}
}
long documentId = super.upload(sid, docId, folderId, release, filename, language, datah);
return Response.ok("" + documentId).build();
} catch (Throwable t) {
log.error(t.getMessage(), t);
return Response.status(500).entity(t.getMessage()).build();
}
}
当我安装logicaldoc的二进制发行版时，我可以使用REST端点。
现在，当我下载源代码并从源代码构建它时，我的响应始终包含以下内容：
javax.ws.rs.core.Response $ ResponseBuilder.status（ILjava / lang / String;）Ljavax / ws / rs / core / Response $ ResponseBuilder;
通常它应该包含新的documentId作为字符串。
在Eclipse中调试时，java代码中的documentId包含新的documentId作为长值（例如119）。
有人可以给我一些提示吗？
谢谢。
在C＃控制台应用程序中，有趣的部分看起来像这样
var contents = result.Result.Content.ReadAsStringAsync().Result;
Console.WriteLine("created documentID: " + contents);
内容之前包含documentId。现在，它返回该对象描述字符串。
根据要求：这是用于上载我所有扫描文档的完整控制台应用程序代码。

通常，在JAX-RS中，将有一些提供程序将自动进行POJO <-> JSON转换。
在您的情况下，由于缺少JSON映射器，可能是您或默认情况下正在完成toString（）。
我通常使用Jersey实现JAX-RS。泽西岛可以使用Jackson启用自动转换。
您可以查看本教程以了解更多信息： https://www.mkyong.com/webservices/jax-rs/json-example-with-jersey-jackson/
Maven依赖关系必须正确，并且应该启用POJO映射功能（在web.xml中）。
注意： 由于是以声明方式添加的，因此可能很难调试。 但是，如果启用了该功能，但仍然缺少类，我希望它会引发一些异常。

我找到了解决方法。
我需要将javax软件包降级到2.0.1版，现在它又可以工作了。
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0.1</version>
</dependency>
