Spring Boot 分分钟搞定支付宝支付功能

1. 首先加入依赖

<dependency>
           <groupId>com.alipay.api</groupId>
           <artifactId>k12-alipay-sdk</artifactId>
           <version>0.0.1-beta</version>
</dependency>

application.properties中配置支付宝相关属性

2.发起支付请求调起支付页面

@RequestMapping("/alipay")
   public void alipay(HttpServletRequest request, HttpServletResponse response,
           @RequestParam(value = "orderNo", required = false, defaultValue = "12313131") String orderNo,
           @RequestParam(value = "clientType", required = false, defaultValue = "1") int clientType) {
       AlipayTradeWapPayModel atpm = new AlipayTradeWapPayModel();
       // 默认一种商品一个订单号
       atpm.setOutTradeNo(orderNo);
       atpm.setTotalAmount(Tools.toString(10));
       atpm.setSubject("测试");

       ClientType ct = ClientType.values()[clientType];
       String resultform = alipayService.payJump(atpm, ct);

       response.setCharacterEncoding("utf-8");
       response.setContentType("text/html; charset=utf-8");
       try {
           response.getWriter().print(resultform);
           response.getWriter().flush();
           response.getWriter().close();
       } catch (IOException e) {
           e.printStackTrace();
       }
   }
