ssh整合思想 Spring与Hibernate和Struts2的action整合 调用action添加数据库 使用HibernateTemplate的save(entity)方法 update delete get 等方法crud操作

package com.swift.action;

import com.opensymphony.xwork2.ActionSupport;
import com.swift.service.UserService;

public class UserAction extends ActionSupport {
    private UserService userService;
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
    @Override
    public String execute() throws Exception {
        System.out.println("action..................");
        userService.add();
        userService.update();
        userService.delete();
        userService.getOne();
        userService.findAll();
        userService.findYouWant();
        return NONE;
    }

}

package com.swift.service;

import org.springframework.transaction.annotation.Transactional;

import com.swift.dao.UserDao;
@Transactional
public class UserService {

    private UserDao userDao;
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
    public void add() {

        userDao.add();
    }

        userDao.update();
    }
    public void delete() {
        System.out.println("UserService.................delete");
        userDao.delete();
    }
    public void getOne() {
        System.out.println("UserService.................get the 3rd");
        userDao.getOne();
    }
