一些重要的代码：

appctx.xml

</beans>

UserController.java

package com.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.domain.User;
import com.service.UserService;

@Controller
@RequestMapping("/user")
public class UserController{
    @Autowired

        userService.register(user);
        
        ModelAndView mav=new ModelAndView();
        
        mav.setViewName("registerOk");

        return mav;
    }

        return mav;
    }
}

 

User.java

package com.domain;

public class User{
    private String userName;
    
    private String userPswd;
