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

UserAction类代码：

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;
    }

}

调用UserService类中crud各种方法

UserService类代码：

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() {
        System.out.println("UserService.................add");
        userDao.add();
    }
    public void update() {
        System.out.println("UserService.................update");
        userDao.update();
    }
    public void delete() {
        System.out.println("UserService.................delete");
        userDao.delete();
    }
    public void getOne() {
        System.out.println("UserService.................get the 3rd");
        userDao.getOne();
    }
    public void findAll() {
        System.out.println("UserService.................find all");
        userDao.findAll();
    }
    public void findYouWant() {
        System.out.println("UserService.................find you want");
        userDao.findYouWant();
    }
    
}

调用UserDao接口

package com.swift.dao;

public interface UserDao {
    public void add();
    public void update();
    public void delete();
    public void getOne();
    public void findAll();
    public void findYouWant();
}

接口实现类UserDaoImplements

package com.swift.dao;

import java.util.List;

import org.springframework.orm.hibernate5.HibernateTemplate;

import com.swift.entity.User;

public class UserDaoImplements implements UserDao{
    private HibernateTemplate hibernateTemplate;
    private User user;
    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }
    public void setUser(User user) {
        this.user = user;
    }

    @Override
    public void add() {
        //增加
        user.setUsername("small-fly");
        user.setAddress("War of Mercenaries");
        hibernateTemplate.save(user);
    }

    @Override
    public void update() {
        //修改
        user.setUsername("big-dog");
        user.setAddress("The War of Mercenaries");
        hibernateTemplate.update(user);
    }
    @Override
    public void delete() {
        hibernateTemplate.delete(user);
    }
    @Override
    public void getOne() {
        User user=hibernateTemplate.get(User.class, 2);
        System.out.println(user.getUsername()+" :: "+user.getAddress());
    }
    @Override
    public void findAll() {
        List<User> list=(List<User>) hibernateTemplate.find("from User");
        for(User user:list) {
            System.out.println(user.getUsername()+" :: "+user.getAddress());
        }
    }
    @Override
    public void findYouWant() {
        List<User> list=(List<User>) hibernateTemplate.find("from User where userName=? and address=?","ram","The War of Mercenaries");
        for(User user:list) {
            System.out.println(user.getUsername()+" :: "+user.getAddress());
        }
    }

}

运行Apach服务器，地址栏输入action

控制台结果

Spring Hibernate Struts2等的 xml配置文件和映射文件，以及实体类和前一篇随笔大致相同。

bean.xml的Spring核心配置文件略有不同，因为在接口实现类UserDaoImplements中，没有直接生成对象，而是通过bean.xml配置文件注入属性得到的对象user。

即配置文件中生成对象user并注入UserDaoImplements中
