jersey上传文件解决办法

这两天在使用jersey 构建的jersey JAX-RS REST服务器，在通过POST方法上传文件的时候,如果根据example来操作的话会引发如下异常：

 SEVERE: Missing dependency for method public javax.ws.rs.core.Response com.lotame.ws.api.resources.FileResource.uploadFile(java.io.InputStream,com.   sun.jersey.core.header.FormDataContentDisposition) at parameter at index

 SEVERE: Missing dependency for method public javax.ws.rs.core.Response com.lotame.ws.api.resources.FileResource.uploadFile(java.io.InputStream,com.   sun.jersey.core.header.FormDataContentDisposition) at parameter at index

 SEVERE: Method, public javax.ws.rs.core.Response com.lotame.ws.api.resources.FileResource.uploadFile(java.io.InputStream,com.sun.jersey.core.header  .FormDataContentDisposition), annotated with POST of resource, class com.lotame.ws.api.resources.FileResource, is not recognized as valid resource   method.

或者

  HTTP -Unsupported Media Type Error

在网上查了好多，貌似都不能解决我遇到的问题，然后就不用他本身提供的例子，下面是我实现上传功能的例子：

1：创建一个JAVA Web工程：

2:XML文件

 <?xml version="1.0" encoding="UTF-8"?>

 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

   <display-name>Restful Web Application</display-name>

     <servlet>

         <servlet-name>jersey-helloworld-serlvet</servlet-name>

         <servlet-class>

                      com.sun.jersey.spi.container.servlet.ServletContainer

                 </servlet-class>

         <init-param>

              <param-name>com.sun.jersey.config.property.packages</param-name>

              <param-value>upload</param-value>

         </init-param>

         <load-on-startup></load-on-startup>

     </servlet>

     <servlet-mapping>

         <servlet-name>jersey-helloworld-serlvet</servlet-name>

         <url-pattern>/rest/*</url-pattern>

     </servlet-mapping>

 </web-app>

3：ImageResource类中的内容

 package upload;

 import java.io.File;

 import java.util.Iterator;

 import java.util.List;

 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 org.apache.tomcat.util.http.fileupload.FileItem;

 import org.apache.tomcat.util.http.fileupload.FileItemFactory;

 import org.apache.tomcat.util.http.fileupload.FileUploadException;

 import org.apache.tomcat.util.http.fileupload.disk.DiskFileItemFactory;

 import org.apache.tomcat.util.http.fileupload.servlet.ServletFileUpload;

 @Path("/images")

 @Consumes(MediaType.MULTIPART_FORM_DATA)

 public class ImageResource {

     private static final String SERVER_UPLOAD_LOCATION_FOLDER = "C://";

     @POST

     @Produces(MediaType.APPLICATION_JSON)

     public String uploadStatePolicy(@Context HttpServletRequest request) {

         try {

             String fileName = saveFile(request);

             if (!fileName.equals("")) {

             } else {

             }

         } catch (Exception ex) {

         }

         return "";

     }

     private String saveFile(HttpServletRequest request) {

         String fileName = "";

         try {

             if (ServletFileUpload.isMultipartContent(request)) {

                 FileItemFactory factory = new DiskFileItemFactory();

                 ServletFileUpload upload = new ServletFileUpload(factory);

                 List<FileItem> items = null;

                 try {

                     items = upload.parseRequest(request);

                 } catch (FileUploadException e) {

                     e.printStackTrace();

                 }

                 if (items != null) {

                     Iterator<FileItem> iter = items.iterator();

                     while (iter.hasNext()) {

                         FileItem item = iter.next();

                         if (!item.isFormField() && item.getSize() > ) {

                             fileName = processFileName(item.getName());

                             try {

                                 item.write(new File(

                                         SERVER_UPLOAD_LOCATION_FOLDER

                                                 + fileName));

                             } catch (Exception e) {

                                 e.printStackTrace();

                             }

                         }

                     }

                 }

             }

         } catch (Exception e) {

         }

         return fileName;

     }

     private String processFileName(String fileNameInput) {

         String fileNameOutput = null;

         fileNameOutput = fileNameInput.substring(

                 fileNameInput.lastIndexOf("\\") + , fileNameInput.length());

         return fileNameOutput;

     }

 }

4：form.html文件

 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Strict//EN" "http://www.w3.org/TR/html4/strict.dtd">

 <html>

 <head>

 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

 <title>Form Page</title>

 </head>

 <body>

 <h1>Upload a File</h1>

     <form action="http://localhost:8080/JerseyUpLoad/rest/images" method="post" enctype="multipart/form-data">

        <p>

         Select a file : <input type="file" name="file" size="" />

        </p>

        <input type="submit" value="Upload It" />

     </form>

 </body>

 </html>

5运行即可。
