我使用SpringTemplateProject创建了一个项目,并在其中使用了 hibernate。
我创建了一个表单并在发布时将值插入到数据库中,但问题是我无法在 POST 上显示这些值。
这是代码:
//控制器
package com.projects.data;
import java.util.Locale;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.projects.data.*;
@Controller
public class HomeController {
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
@Autowired
ServiceImpl service;
@RequestMapping(value = "/", method = RequestMethod.GET)
public ModelAndView customer() {
return new ModelAndView("home", "command", new Customer());
}
@RequestMapping(value = "/customer", method = RequestMethod.POST)
public String addCustomer(@ModelAttribute("customer") Customer customer,ModelMap model)
{
model.addAttribute("custid",customer.getCustId());
model.addAttribute("name", customer.getName());
model.addAttribute("age", customer.getAge());
service.addCustomer(customer);
return "customer/customer";
}
}
