}

CustomerController

package com.shpun.controller;

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

    @Autowired
    private CustomerService customerService = null;

    // 跳转到添加Customer的jsp
    @RequestMapping(value = "/add",method = RequestMethod.GET)
    public ModelAndView addCustomer(){
        System.out.println("to AddCustomer.jsp");

        ModelAndView mv = new ModelAndView();
        mv.setViewName("AddCustomer");
        return mv;
    }

    // 添加完Customer后重定向到home的jsp

    public String toDeleteCustomer(@RequestParam("id")String id){
        System.out.println("to delete customer id :"+id);

        System.out.println("to delete over customer id :"+id);

        return "redirect:/home/get";
    }

        ModelAndView mv = new ModelAndView();

        mv.addObject("customer",customer);
        return mv;
    }

    // 更新完Customer后重定向到home的jsp

    }

    // 跳转到查询Customer页面
    @RequestMapping(value = "/toSearch",method = RequestMethod.POST)
    public ModelAndView toSearchCustomer(Customer customer){
        System.out.println("to search");

        List<Customer> customerList = customerService.searchCustomers(customer);

        ModelAndView mv = new ModelAndView();
        mv.setViewName("SearchCustomerResult");
        mv.addObject("customerList",customerList);
        return mv;
    }

}

PS:

springMVC传值到jsp失败，可能是忘记修改web.xml的webapp

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1" metadata-complete="true">
