ssh框架整合实例子-业务层

1. 业务层接口 UserService

package com.yanek.demo.ssh.service;

import java.util.List;

import com.yanek.demo.ssh.vo.User;

public interface UserService {
 
 
 public void save(User user);
 public List<User> findAll();
}

2. 业务层接口实现类  UserServiceImpl

package com.yanek.demo.ssh.service;

import java.util.List;

import com.yanek.demo.ssh.dao.UserDAO;
import com.yanek.demo.ssh.vo.User;

public class UserServiceImpl implements UserService {

 private UserDAO userDAO;// userDao类

 public UserDAO getUserDAO() {
  return userDAO;
 }

 public void setUserDAO(UserDAO userDAO) {
  this.userDAO = userDAO;
 }

 public void save(User user) {

  userDAO.save(user);

 }
 
 public List<User> findAll()
 {
  
  return userDAO.findAll();
 }

}
