它是文件下载的更好方法和简单方法。
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();
}
}
};
}
