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 0
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 1
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 415-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>1</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() > 0) {
                            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("\") + 1, 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="50" />
       </p>

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

</body>
</html>

5运行即可。
