本文介绍了一个使用Spring框架实现用户注册功能的示例代码。通过整合Hibernate进行数据库操作，演示了如何在Dao层保存用户信息，Service层处理业务逻辑以及Controller层接收请求并调用Service层的方法。

//Dao层

package com.bear.cakeonline.test;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.stereotype.Repository;

import com.bear.cakeonline.entity.UserInfo;
import com.bear.cakeonline.entity.UserLogin;

@Repository
public class TestDaoImpl {

@Resource
private SessionFactory sessionFactory;

public void saveUser(){
UserLogin ul=new UserLogin();
ul.setLoginName("zs");
ul.setPassword("123");

UserInfo ui=new UserInfo();
ui.setRealName("zhangsan");
ul.setUserInfo(ui);
ui.setUserLogin(ul);
Session s=this.sessionFactory.openSession();
Transaction t=s.beginTransaction();
s.save(ul);
t.commit();
s.close();
}

}

//service层

package com.bear.cakeonline.test;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional(readOnly=false)
public class TestServiceImpl {

@Resource
private TestDaoImpl testDaoImpl;

public void regist(){
this.testDaoImpl.saveUser();
}
}

//controller层

package com.bear.cakeonline.test;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/test")
public class TestController {

@Resource
private TestServiceImpl testServiceImpl;

@RequestMapping("/regist")
public String regist(){
System.out.println("lskdfj");
this.testServiceImpl.regist();
return "";
}
}
