异步通知是指在某个操作完成后,系统会给指定的URL发送一个HTTP请求,通知该操作的结果。在Java中,可以通过Servlet或Spring MVC的Controller来实现异步通知的接收和处理。下面是一个示例代码:
```java
@WebServlet("/notify")
public class NotifyServlet extends HttpServlet {
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// 读取异步通知参数
String notifyTime = request.getParameter("notifyTime");
String notifyType = request.getParameter("notifyType");
String notifyId = request.getParameter("notifyId");
String charset = request.getParameter("charset");
String version = request.getParameter("version");
String signType = request.getParameter("signType");
String sign = request.getParameter("sign");
String appId = request.getParameter("appId");
String bizContent = request.getParameter("bizContent");
// 验证参数签名
boolean signVerified = verifySign(notifyTime, notifyType, notifyId, charset, version, signType, sign, appId, bizContent);
if (signVerified) {
// 参数签名验证通过,处理业务逻辑
String orderNo = request.getParameter("orderNo");
String bizOrderNo = request.getParameter("bizOrderNo");
String amount = request.getParameter("amount");
String status = request.getParameter("status");
// TODO: 处理异步通知结果
// 返回通知结果
response.getWriter().write("success");
} else {
// 参数签名验证失败,忽略该通知
response.getWriter().write("fail");
}
}
private boolean verifySign(String notifyTime, String notifyType, String notifyId, String charset, String version, String signType, String sign, String appId, String bizContent) {
// TODO: 实现签名验证逻辑
return true;
}
}
```
在这个示例中,我们通过@WebServlet注解将NotifyServlet映射到/notify路径上,然后在doPost方法中读取异步通知的参数,并验证参数签名。如果签名验证通过,则处理业务逻辑并返回success响应;否则返回fail响应。在verifySign方法中,我们可以通过调用第三方支付平台提供的SDK来实现签名验证逻辑。
