[这里，我的问题是在控制器中的请求映射已完成，但是在http://localhost:8080/web-customer-tracker/customer/list上运行代码时，出现的错误是org.springframework.web.servlet.DispatcherServlet noHandlerFound 警告：GET / web-customer-tracker / customer / list
没有映射[请在这里帮助我解决它，我已经上传了控制器和web.xml代码段。
这是CustomerController代码段
package Controllers;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/customer")
public class CustomerController {
@RequestMapping("/list")
public String listCustomers(Model theModel) {
return "list-customers";
}
}
这是web.xml代码段
<?xml version="1.0" encoding="UTF-8"?>

您是否设置了上下文路径？如果没有，则在application.properties文件中添加以下属性。server.servlet.contextPath=/web-customer-tracker
或如下设置环境变量Set SERVER_SERVLET_CONTEXT_PATH=/web-customer-tracker
