基于springBoot使用templates技术

1.引入maven依赖:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

2.编写freemark文件。(freemarker在springboot2.20后的版本后缀是ftlh)

<script>
    function onBridgeReady(){
        WeixinJSBridge.invoke(
            'getBrandWCPayRequest', {
                "appId":"${payResponse.appId}",     //公众号名称,由商户传入
                "timeStamp":"${payResponse.timeStamp}",         //时间戳,自1970年以来的秒数
                "nonceStr":"${payResponse.nonceStr}", //随机串
                "package":"${payResponse.packAge}",
                "signType":"${payResponse.signType}",         //微信签名方式:
                "paySign":"${payResponse.paySign}" //微信签名
            },
            function(res){
                if(res.err_msg == "get_brand_wcpay_request:ok" ){
                    // 使用以上方式判断前端返回,微信团队郑重提示:
                    //res.err_msg将在用户支付成功后返回ok,但并不保证它绝对可靠。
                }
            });
    }
    if (typeof WeixinJSBridge == "undefined"){
        if( document.addEventListener ){
            document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
        }else if (document.attachEvent){
            document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
            document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
        }
    }else{
        onBridgeReady();
    }
</script>

 

 

3.编写相应的controller将数据传输至刚刚编写的freemark文件

    @GetMapping("/create")
    public ModelAndView create(@RequestParam("orderId") String orderId,
                               @RequestParam("returnUrl") String returnUrl) {
        //1. 查询订单
        OrderDTO orderDTO = orderService.findOne(orderId);
        if (orderDTO == null) {
            throw new SellException(ResultEnum.ORDER_NOT_EXIST);
        }
        //发起支付
        PayResponse payResponse = payService.create(orderDTO);
        log.info("payResponse={}", JsonUtil.toJson(payResponse));
        Map<String,Object> result=new HashMap<>();
        result.put("payResponse",payResponse);
        result.put("returnUrl",returnUrl);
        return new ModelAndView("pay/create",result);   //将数据传输至freemark文件
    }
