暂时用这种方式来完成功能。

	/**
	 * 查询业务列表
	 */
	@At("/graphql")
	@Ok("json")
	@POST
	@AdaptBy(type = VoidAdaptor.class)
	public Object graphql( HttpServletRequest req) {
		String sql = "";
		try {
			InputStream is = req.getInputStream();
			byte[] bb = Streams.readBytesAndClose(is);
			sql = new String (bb);
		} catch (IOException e) {
			e.printStackTrace();
		}
		return Result.success("system.success",sql);

	}
