我的CustomerController：

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;

import org.springframework.web.bind.annotation.RequestMethod;

import com.pankanis.model.Customer;
import com.pankanis.service.*;

@RequestMapping("/customer")
public class CustomerController {

    CustomerController(){}
    @Autowired 
    private CustomerService serv;

    public CustomerService getServ() {
        return serv;
    }

    public void setServ(CustomerService serv) {
        this.serv = serv;
    }

    @RequestMapping(value="/addCustomer",method=RequestMethod.POST)
    public String AddCustomer(@RequestBody Customer cust,HttpServletRequest request,HttpServletResponse response)
    {       

        String CustomerId = serv.AddCustomer(cust);     
        return CustomerId;

Answer 1

验证所请求的类的名称是否正确以及类路径中是否存在相应的.jar文件。如果没有，则必须将其显式添加到应用程序的类路径中。

如果您的类路径中存在指定的.jar文件，那么您的应用程序的类路径将被覆盖，您必须找到应用程序使用的确切类路径。

如果异常是由第三方类引起的，则必须标识抛出异常的类，然后在类路径中添加缺少的.jar文件。

希望有所帮助。

Answer 2

尝试公开您的CustomerController构造函数。
