参考大神的工具，大家可以看过来：https://blog.csdn.net/zyw_java/article/details/54024162

一些基本的设置可以参考我这篇h5支付，这里不做赘述：https://blog.csdn.net/goligory/article/details/78392505

<dependency>
      <groupId>com.github.javen205</groupId>
      <artifactId>IJPay</artifactId>
      <version>1.0</version>
    </dependency>

上代码：

public WxPayApiConfig getApiConfig() {
        return WxPayApiConfig.New()
                .setAppId(configBean.getWxAppId())
                .setMchId(configBean.getWxMchId())
                .setPaternerKey(configBean.getWxPartnerKey())
                .setPayModel(WxPayApiConfig.PayModel.BUSINESSMODEL);
    }

/**
	 * 扫码支付模式二
	 * 已测试
	 */
	@RequestMapping(value ="/codePay.do",method = {RequestMethod.POST,RequestMethod.GET})
	public ModelAndView scanCode2(HttpServletRequest request,HttpServletResponse response,
								@RequestParam("total_fee") String total_fee) {
		ModelAndView mv = new ModelAndView();

		String openId="o6L670YbTF929Qdf-e-ehARR_p-k";

		if (StrKit.isBlank(openId)) {
			System.out.println("openid为空");
			return mv;
		}
		if (StrKit.isBlank(total_fee)) {
			System.out.println("支付金额不能为空");
			return mv;
		}

		String ip = IpKit.getRealIp(request);
		if (StrKit.isBlank(ip)) {
			ip = "127.0.0.1";
		}

		System.out.println("ip:"+ip);
		WxPayApiConfigKit.putApiConfig(getApiConfig());
		Map<String, String> params = WxPayApiConfigKit.getWxPayApiConfig()
				.setAttach("IJPay 测试  -By Javen")
				.setBody("IJPay 扫码支付2测试  -By Javen")
				.setOpenId(openId)
				.setSpbillCreateIp(ip)
				.setTotalFee(total_fee)
				.setTradeType(WxPayApi.TradeType.NATIVE)
				.setNotifyUrl(notify_url)
				.setOutTradeNo(String.valueOf(System.currentTimeMillis()))
				.build();

		String xmlResult = WxPayApi.pushOrder(false,params);
		System.out.println("xmlResult:"+xmlResult);

		Map<String, String> resultMap = PaymentKit.xmlToMap(xmlResult);
		System.out.println("解析resultMap:"+resultMap);

		String return_code = resultMap.get("return_code");
		String return_msg = resultMap.get("return_msg");
		if (!PaymentKit.codeIsOK(return_code)) {
			System.out.println("error:"+return_msg);
			return mv;
		}
		String result_code = resultMap.get("result_code");
		if (!PaymentKit.codeIsOK(result_code)) {
			return mv;
		}
		//生成预付订单success


		String qrCodeUrl = resultMap.get("code_url");
		System.out.println("codeurl链接："+qrCodeUrl);

		mv.addObject("codeUrl",qrCodeUrl);
		mv.setViewName("Qrcode");
		return mv;
	}

这个是原来的请求方式，大家可以自行按照自己的方式更改成restful形式的，最后生成qrCodeUrl，将其返回给前端生成二维码即可，回调在在h5支付那篇文章中

其他的jar如果找不到去这里看一下，这是h5支付和公众号支付，把扫码支付集成进去就行：http://download.csdn.net/download/goligory/10044575
