MULTIPART_FORM_DATA：找不到类型为public javax.ws.rs.core.Response的参数的注入源 [英] MULTIPART_FORM_DATA: No injection source found for a parameter of type public javax.ws.rs.core.Response
问题描述
我正在使用基于Jersey的restful Service实施策略来构建将用于上传文件的服务。
我的服务类名称是：UploadFileService.java（参见下面的代码）
I am using Jersey based restful Service implementation strategy to build a service which will be used to upload files. My service class name is : UploadFileService.java (See Code below)
package com.jerser.service;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;
@Path("/fileUpload")
public class UploadFileService {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
这些是我在lib中的JAR文件：

在互联网上我发现有很多例子其中显示了如何使用RESTFul API上传MULTIPART文件。但同样的解决方案。我也无法运行这些代码。
我认为我对JAR文件做错了。有人可以帮我吗？
Over the internet I found there are plenty of example which shows How to upload MULTIPART file using RESTFul API. But with same solution. I am not able to run those code as well. I think I am doing something wrong with the JAR files. Could anyone please help me on this?
推荐答案
摆脱 jersey-multipart-1.18.jar 。这是泽西岛1.x.添加这两个
Get rid of jersey-multipart-1.18.jar. That is for Jersey 1.x. Add these two
- jersey-media-multipart-2.17
- mimepull-1.9.3
对于Maven，您将使用以下依赖项（您不需要显式添加 mimepull 依赖，因为这个将拉进去。）
For Maven you would use the following dependency (you don't need to explicitly add the mimepull dependency, as this one will pull it in).
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.17</version> <!-- Make sure the Jersey version matches
the one you are currently using -->
</dependency>
然后你需要注册 MultiPartFeature 。如果您使用 ResourceConfig 进行配置，您只需执行
Then you need to register the MultiPartFeature. If you are using a ResourceConfig for configuration, you can simply do
register(MultiPartFeature.class);
如果您使用的是web.xml，则可以将该类添加为< init-param> 到Jersey servlet
If you are using web.xml, then you can add the class as an <init-param> to the Jersey servlet
<init-param>
<param-name>jersey.config.server.provider.classnames</param-name>
<param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>
请注意，如果您要注册多个提供程序，则可以使用以下方式分隔每个提供程序类：逗号或分号。您不能两次使用相同的 param-name 。请参阅 Suarabh的回答
Note that if you have multiple providers that you want to register, then you can delimit each provider class with a comma or semicolon. You cannot use this same param-name twice. See Suarabh's answer
更新
此外，一旦你摆脱了 jersey-multipart-1.18.jar ，你将会遇到失踪的编译错误进口课程。在大多数情况下，类名仍然相同，只是包已更改，即
Also, once you get rid of jersey-multipart-1.18.jar you will have compile errors for the missing imported classes. For the most part, the class names are still the same, just the packages have changed, i.e.
-
org.glassfish.jersey.media .multipart.FormDataParam -
org.glassfish.jersey.media.multipart.FormDataContentDisposition
org.glassfish.jersey.media.multipart.FormDataParamorg.glassfish.jersey.media.multipart.FormDataContentDisposition
如果你来这里是为了另一个 ModelValidationException ，这里有一些链接，提供有关异常的其他原因的信息。
If you are here for a different ModelValidationException, here are some links for information on other causes of the exception.
