spring2.3.4+hibernate3+struts2.3.4

实现一个简单实现也没，往数据库中注册一个用户，使用声明式事务管理对service层进行事务管理。

整个项目分三个层面，dao层处理数据库，action层处理也面请求和跳转，service层处理业务逻辑。

使用的struts2.3.4+spring3.2+hibernate3，数据库为mysql

数据库名为spring，数据库表为user，表结构为id int，name varchar，password varchar

后台页面：

RegistAction.java如下：

 

package com.cvicse.action;

 

import com.cvicse.db.User;

import com.cvicse.service.UserService;

import com.opensymphony.xwork2.ActionSupport;

 

public class RegistAction extends ActionSupport {

 

private static final long serialVersionUID = 5009307619469258933L;

private String name;

private String password;

private UserService userService;

 

@Override

public String execute() throws Exception {

User user = new User();

user.setName(name);

user.setPassword(password);

 

userService.addUser(user);

return SUCCESS;

}

 

public String getName() {

return name;

}

 

public void setName(String name) {

this.name = name;

}

 

public String getPassword() {

return password;

}

 

public void setPassword(String password) {

this.password = password;

}

 

public UserService getUserService() {

return userService;

}

 

public void setUserService(UserService userService) {

this.userService = userService;

}

}

UserService的代码如下：

package com.cvicse.service;

import com.cvicse.dao.UserDAO;

import com.cvicse.db.User;

public class UserService {

private UserDAO userDao;

public void addUser(User user){

userDao.save(user);

}

public UserDAO getUserDao() {

return userDao;

}

public void setUserDao(UserDAO userDao) {

this.userDao = userDao;

}

}

UserDAO代码如下：

package com.cvicse.dao;

import org.springframework.orm.hibernate3.HibernateTemplate;

import com.cvicse.db.User;

public class UserDAO {

private HibernateTemplate hibernateTemplate;

public void save(User user){

hibernateTemplate.save(user);

}

public HibernateTemplate getHibernateTemplate() {

return hibernateTemplate;

}

public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {

this.hibernateTemplate = hibernateTemplate;

}

}

实体类User.java的代码如下：

package com.cvicse.db;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.Id;

@Entity

public class User {

private int id;

private String name;

private String password;

@Id

@GeneratedValue

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

}
