这是我到目前为止
这将初始化我的REST服务
package com.dothatapp.web.rest;
import javax.servlet.annotation.MultipartConfig;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("/authed/rest")
public class JaxRsActivator extends Application {
}
这是我的服务看起来像
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.UriInfo;
import org.json.JSONObject;
@Path("fileupload")
public class FileUpload {
@Context
private UriInfo context;
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public JSONObject doUpload(@Context HttpServletRequest obj) {
try {
obj.getParts();
} catch (Exception e) {
e.printstacktrace();
}
System.out.println(us);
System.out.println(es);
System.out.println(obj);
return null;
}
}
我尝试添加@MultipartConfig到JaxRsActivator,但我仍然得到一个异常：Request.getParts被调用没有多部分配置.可以将@MultipartConfig添加到servlet,或者将multipart-config元素添加到web.xml.
3-12-08T17:03:05.013+0000|SEVERE: java.lang.IllegalStateException: Request.getParts is called without multipart configuration. Either add a @MultipartConfig to the servlet,or a multipart-config element to web.xml

谢谢
解决方法
最后,我设法得到这个工作,没有泽西耦合.
问题是@Multipart注释不适用于应用程序,因此您需要在web.xml中定义它,并在Application类中定义提供的服务.在服务内部,您可以正常使用注释.另请注意,我从请求中提取部件,但这很容易.

PS.这实际上实现了bluimp JQuery file upload的后端
