Question

我想使用 restfull webservice上传文件。当我曝光时这个休息服务，我得到500 *（内部服务器错误）*。

resource.java类

   @Path("/resource")
   public class Demo{
   private static final String FOLDER_PATH = "C:/uploaded_license/";    
      @POST
      @Path("/upload")
      @Consumes(MediaType.MULTIPART_FORM_DATA)
      @Produces(MediaType.TEXT_PLAIN)
      public String uploadFile(@FormDataParam("file") InputStream fis,
           @FormDataParam("file") FormDataContentDisposition fdcd) {

         OutputStream outpuStream = null;
         String fileName = fdcd.getFileName();
         System.out.println("File Name: " + fdcd.getFileName());
         String filePath = FOLDER_PATH + fileName;

         try {
             int read = 0;
             byte[] bytes = new byte[1024];
             outpuStream = new FileOutputStream(new File(filePath));
             while ((read = fis.read(bytes)) != -1) {
                 outpuStream.write(bytes, 0, read);
             }
             outpuStream.flush();
             outpuStream.close();
         } catch(IOException iox){
             iox.printStackTrace();
         } finally {
             if(outpuStream != null){
                 try{outpuStream.close();} catch(Exception ex){}
             }
         }
         return "File Upload Successfully !!";
    }
  }

This is the rest service in which *FOLDER_PATH* is the path where the 
uploaded file will saved.

upload.html

Answer 1

我认为你需要inti ApplicationContext.xml。防爆。： -

 <servlet>
    <servlet-name>myServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ApplicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
