我有以下 Web 服务，该服务应该通过 HTML 表单获取文件并将其保存在服务器上的某个位置。
@Path("/dv")
public class Uploader {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(@FormDataParam("file") InputStream stream, @FormDataParam("file") FormDataContentDisposition fileDetails) {
FileOperations fo = new FileOperations(stream); // My own class
try {
fo.saveToFile(fileDetails.getFileName());
} catch (IOException ex) {
ex.printStackTrace();
}
return Response.status(200).entity("").build();
}
}
HTML 表单是这样的。
<form name="upload-form" method="post" action="http://localhost:18080/dv/upload" enctype="multipart/form-data">
<input type="file" name="file" id="file" />
<input type="submit" />
</form>
每当我通过此表单上传文件时，都会收到错误
javax.ws.rs.NotSupportedException: Could not find message body reader for type: class com.sun.jersey.core.header.FormDataContentDisposition of content type: multipart/form-data;boundary=----WebKitFormBoundaryHvAymGjNVVEB1VWa
这是堆栈跟踪

问题是我不明白这里的问题是什么。我已将 @Consumes(MediaType.MULTIPART_FORM_DATA) 更改为 @Consumes("multipart/form-data") 但出现相同的错误。
浏览器发送具有以下Content-Type的HTTP数据包
Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryHvAymGjNVVEB1VWa
我从服务器收到了 415 响应
415 Unsupported Media Type
如果有帮助，我正在使用 Google Chrome。
最佳答案
peeskillet是正确的。我使用了不正确的依赖项。我更新了我的 pom.xml 文件以包含 RESTEasy jar，它开始工作。
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-multipart-provider</artifactId>
</dependency>
