Struts2.2+Spring3.1+Hibernate3.6整合(登录示例及CRUD操作)

2011-08-11 01:06 806 查看

一运行环境: XP3+Myeclipse6.6+Tomcat7

二项目框架版本号:Struts2 version: 2.2.1.1,Spring version: 3.1,Hibernate version:3.6,在Hibernate下有个jar为:javassist-3.12.0.GA.jar,在这个示例中用的是:javassist-3.7.ga.jar,这二个在这个示例中都可以用,没问题,一般原则用新版本的

项目所用jar文件如下图

三具体实现如下:

1 配置文件:

2 Java代码如下:

A WEB层:

}

protected Map<String,Object> getSession(){

return (Map<String,Object>)ActionContext.getContext().getSession();

}

}

UserAction Code:

Java代码

public void editUser(User user);

public void delUser(User user);

public List<User> getUserList();

public User getUserByUid(User user);

}

UserServiceImpl Code:

//user.setId(id);

System.out.println("添加: "+user);

private String username = null;

private String password = null;

private String address = null;

private String sex = null;

private Integer age = null;

return address;

}

public void setAddress(String address) {

return username;

}

public void setUsername(String username) {

}

public String getPassword() {

return password;

}

}

/*

* 适合ID为int,short,long的情况

* @Id

*/

@Id

@GeneratedValue(generator="system-uuid")

@GenericGenerator(name="system-uuid", strategy = "uuid")

public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public String getSex() {

return sex;

}

public void setSex(String sex) {

}

@Override

public String toString() {

return "name: " + username + ",password: " + password+",sex: " + sex + ",age: " + age+",address: " + address + ",id: " + id;

}

}

DAO层:

UserDAO Code:

Java代码

import java.util.List;

import com.liuzd.s2sh.entity.User;

public interface UserDAO {

/**

* 检查用户是否存在

* */

public User getUserByUserIdAndUserNameExits(User user);

public void saveUser(User user);

public void updateUser(User user);

public User getUser(User user);

public void delUser(User user);

public List<User> finUserAll();

}

UserDAOImpl Code:

Java代码

import java.util.List;

import javax.annotation.Resource;

import org.springframework.orm.hibernate3.HibernateTemplate;

import org.springframework.stereotype.Component;

import com.liuzd.s2sh.dao.UserDAO;

import com.liuzd.s2sh.entity.User;

@Component("userDao")

public class UserDAOImpl implements UserDAO {

private HibernateTemplate hibernateTemplate;

public HibernateTemplate getHibernateTemplate() {

return hibernateTemplate;

}

@Resource

public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {

this.hibernateTemplate = hibernateTemplate;

}

public User getUserByUserIdAndUserNameExits(User user) {

List<User> users = hibernateTemplate.find("from User u where u.username = '" + user.getUsername() + "' and u.password='"+user.getPassword()+"'");

if (users != null && users.size() > 0) {

return users.get(0);

}

return null;

}

@Override

public void saveUser(User user) {

this.hibernateTemplate.save(user);

}

@Override

public void delUser(User user) {

User delUser = getUser(user);

this.hibernateTemplate.delete(delUser);

}

@Override

public List<User> finUserAll() {

return this.hibernateTemplate.find("from User");

}

@Override

public User getUser(User user) {

return this.hibernateTemplate.load(User.class,user.getId());

}

@Override

public void updateUser(User user) {

this.hibernateTemplate.update(user);

}

}
