它是下载文件的更好方法和简便方法。
private static final String FILE_PATH = "d:\Test2.zip";@GET@Path("/get")@Produces(MediaType.APPLICATION_OCTET_STREAM)public Response getFile() { File file = new File(FILE_PATH); ResponseBuilder response = Response.ok((Object) file); response.header("Content-Disposition", "attachment; filename=newfile.zip"); return response.build();}对于您所要求的代码：
@GET@Path("/helloWorldZip") @Produces(MediaType.APPLICATION_OCTET_STREAM)public StreamingOutput helloWorldZip() throws Exception { return new StreamingOutput(){ @Override public void write(OutputStream arg0) throws IOException, WebApplicationException { // TODO Auto-generated method stub BufferedOutputStream bus = new BufferedOutputStream(arg0); try { //ByteArrayInputStream reader = (ByteArrayInputStream) Thread.currentThread().getContextClassLoader().getResourceAsStream(); //byte[] input = new byte[2048]; java.net.URL uri = Thread.currentThread().getContextClassLoader().getResource(""); File file = new File("D:\Test1.zip"); FileInputStream fizip = new FileInputStream(file); byte[] buffer2 = IOUtils.toByteArray(fizip); bus.write(buffer2); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } };}
