The latest version of the Java Alipay interface!

Technology: Java+SpringBoot+Maven+Sandbox Test

Time: Released on March 1, 2022

There is not much introduction to adding Web modules to new SpringBoot, and it will definitely be

Add Alipay dependency

<dependency>
    <groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>4.22.32.ALL</version>
</dependency>

Start configuring the sandbox

Address: https://open.alipay.com/platform/appDaily.htm

In the old version, the public key and private key need to be automatically generated, but the new version has already generated it for you, and you can use it directly...

Sandbox Introduction:

Click on the public key mode to view , which is used later in the parameters

An account is a buyer and a seller is relatively simple , so I will introduce it here, and start to code below

Simulate a page to facilitate POST requests, the code is as follows

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>支付宝支付测试</title>
    </head>
    <body>
        <h1>商品购买页面</h1>
        <form action="/buy" method="post">
            <p>商品单号:<input type="text" name="out_trade_no"></p>
            <p>商品名称:<input type="text" name="subject"></p>
            <p>付款金额:<input type="text" name="total_amount"></p>
            <p>商品描述:<input type="text" name="body"></p>
            <p>支付超时时间:<input type="text" name="timeout_express"></p>
            <p>销售产品码:<input type="text" name="product_code"></p>
            <p><input type="submit" value="提交"></p>
        </form>
    </body>
</html>

Start to do some basic configuration for the transaction. The following config classes are all annotated, so I won’t introduce them one by one. Most of them are the parameters used when introducing the sandbox above.

I will jump to Baidu if the payment is successful here, you can according to your needs

If you don't like to use Java classes, you can also use configuration files. After that, the IO reading is the same. The code is as follows

Next, write the Controller layer

/**

 * @describeL: 支付宝支付接口
 */
@Controller
public class ShopAlipayController {
      
      

    @PostMapping("/buy")
    @ResponseBody
    //这个接收的参数就是前端页面那几个参数,这是MVC的东西,如果可以我建议你封装一个DTO对象啥的...
    public String test(HttpServletResponse response, String out_trade_no, String subject, String total_amount, String body, String timeout_express, String product_code) throws IOException {
      
      
        /**
		 * 支付宝签名方式,参数讲解,跟配置类里面的参数是照应的,如果不想要配置类,直接把值写到这里面也ok

		 * 4.返回格式
		 * 5.编码格式
		 * 6.支付宝公钥
		 * 7.加密方式
		 */
        AlipayClient alipayClient = new DefaultAlipayClient(
            AliPayConfig.URL,
            AliPayConfig.APPID,
            AliPayConfig.RSA_PRIVATE_KEY,
            AliPayConfig.FORMAT,
            AliPayConfig.CHARSET,
            AliPayConfig.ALIPAY_PUBLIC_KEY,
            AliPayConfig.SIGNTYPE
        );
        //创建Request请求,这个是支付宝提供的
        AlipayTradeWapPayRequest request = new AlipayTradeWapPayRequest();
        // 封装参数
        AlipayTradeWapPayModel payModel = new AlipayTradeWapPayModel();
        payModel.setOutTradeNo(out_trade_no);
        payModel.setSubject(subject);
        payModel.setTotalAmount(total_amount);
        payModel.setBody(body);
        payModel.setTimeoutExpress(timeout_express);
        payModel.setProductCode(product_code);
        request.setBizModel(payModel);
        //设置异步地址
        request.setNotifyUrl(AliPayConfig.NOTIFY_URL);
        //设置同步回调地址
        request.setReturnUrl(AliPayConfig.RETURN_URL);
        //生成表单
        String form = null;
        try {
      
      
            form = alipayClient.pageExecute(request).getBody();
        } catch (AlipayApiException e) {
      
      
            e.printStackTrace();
        }
        return form;
    }
}

Then request localhost:8080 to jump to index.html by default, fill in the parameters casually, and the request is over

Browser payment, it is also possible to use a sandbox account, or directly download a sandbox version of the APP

The rest is to jump to Baidu after successful login and payment... The tutorial is over when you get here, come on, be a worker!
