//1. 接收数据,request.getParameter 不能接收json的数据
/* String brandName = request.getParameter("brandName");
System.out.println(brandName);*/
// 获取请求体数据
BufferedReader br = request.getReader();
String params = br.readLine();
// 将JSON字符串转为Java对象
Brand brand = JSON.parseObject(params, Brand.class);
//2. 调用service 添加
brandService.add(brand);
//3. 响应成功标识
response.getWriter().write("success");

}
运行结果及报错内容
能访问这个网页，输入数据，点提交怎么也没反应
我的解答思路和尝试过的方法
搞不懂
我想要达到的结果
把数据提交到http://localhost:8080/brand-demo/addServlet，并且成功跳转到http://localhost:8080/brand-demo/brand.html
