什么样的param需要传递给DAO方法调用

Question

我只想在调用控制器方法时传递我的实体对象。我该怎么做才能将数据插入我的数据库？

RegisterDAO.java

import com.samy.springmvc.beans.RegisterBean;

public interface RegisterDAO {
    void createUser(RegisterBean registerbean);
}

RegisterDAOImpl.java

@Autowired
private SessionFactory sessionFactory;

public void createUser(RegisterBean regbean) {
    // TODO Auto-generated method stub
    Session session = sessionFactory.getCurrentSession();
    Register register= new Register();
    register.setId(regbean.getId());
    register.setUsername(regbean.getUser());
    register.setFirstname(regbean.getFirstname());
    register.setLastname(regbean.getLastname());
    register.setEmail(regbean.getEmail());
    register.setAddress(regbean.getAddress());
    register.setPhone(regbean.getPhonenumber());
    register.setPassword(regbean.getPassword());
    session.save(register);
}

registerationController.java

   @Autowired
    RegisterDAO registerDAO;

    @RequestMapping(value="/login",method=RequestMethod.POST)
        public ModelAndView returnSuccess()
        {
           registerDAO.createUser(new RegisterBean());
           return new ModelAndView("login");
        }

Answer 1

您需要将bean指定为控制器的参数。

1. 如果使用表格

   @RequestMapping(value="/login",method=RequestMethod.POST)
   public ModelAndView returnSuccess(@ModelAttribute RegisterBean regBean)
   { 
     registerDAO.createUser(regBean);
     ... 
   

2. 如果使用JSON

   @RequestMapping(value="/login",method=RequestMethod.POST)
   public ModelAndView returnSuccess(@RequestBody RegisterBean regBean)
   { 
      registerDAO.createUser(regBean);
      ...
