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。
