一：添加三框架jar包

 

二：model层(student.java)     

package com.wdpc.ss2h.model;

public class Student {
	private String id;
	private String userName;//创建姓名
	private String userPwd;//创建密码

	//无参构造
	public Student() {
		super();
	}

	//有参构造
	public Student(String userName, String userPwd) {
		super();
		this.userName = userName;
		this.userPwd = userPwd;
	}

	//get，set方法
	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getUserName() {
		return userName;
	}

	public void setUserName(String userName) {
		this.userName = userName;
	}

	public String getUserPwd() {
		return userPwd;
	}

	public void setUserPwd(String userPwd) {
		this.userPwd = userPwd;
	}
}

   //model层 student配置文件(Student.hbm.xml)  

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
	<class name="com.wdpc.ss2h.model.Student" table="student">
		<id name="id" type="java.lang.String" column="id">
			<generator class="uuid.hex"></generator>
		</id>
		<property name="userName" type="java.lang.String" column="userName" />
		<property name="userPwd" type="java.lang.String" column="userPwd" />
	</class>
</hibernate-mapping>

    此映射文件要放到model层下，和student类放在一起

   //dao层 (StudentDao.java) 

package com.wdpc.ss2h.dao;

import com.wdpc.ss2h.model.Student;

public interface StudentDao {
	//登录
	public Student findName(Student student) throws Exception;
	//注册
	public void createStudent(Student student) throws Exception;
}

     创建dao层接口

   //实现dao层(StudentDaoImpl.java)

package com.wdpc.ss2h.dao.impl;

import java.util.List;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
import com.wdpc.ss2h.dao.StudentDao;
import com.wdpc.ss2h.model.Student;

public class StudentDaoImpl implements StudentDao {
	private SessionFactory sessionFactory;
	//注册
	public void createStudent(Student student) throws Exception {
		sessionFactory.getCurrentSession().save(student);
	}

	//登录
	public Student findName(Student student) throws Exception {
		Query query = sessionFactory.getCurrentSession().createQuery(
		"from Student where userName=:name and userPwd=:password");
		query.setParameter("name",student.getUserName());
		query.setParameter("password",student.getUserPwd());
		List<Student> list = query.list();		
		if (list.size() > 0)
			return list.get(0);
		else
			return null;
	}

	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}	
}

    实现StudentDao.java接口方法

  //service层(StudentService.java)

package com.wdpc.ss2h.service;

import com.wdpc.ss2h.model.Student;

public interface StudentService {
	//登录
	public Student findName(Student student) throws Exception;
	//注册
	public void createStudent(Student student) throws Exception;
}

  //实现service层(StudentServiceImpl.java)

package com.wdpc.ss2h.service.impl;

import com.wdpc.ss2h.dao.StudentDao;
import com.wdpc.ss2h.model.Student;
import com.wdpc.ss2h.service.StudentService;

public class StudentServiceImpl implements StudentService {
	private StudentDao studentDao;
	
	public void createStudent(Student student) throws Exception {
		studentDao.createStudent(student);
	}

	public Student findName(Student student) throws Exception {
		return studentDao.findName(student);
	}

	public void setStudentDao(StudentDao studentDao) {
		this.studentDao = studentDao;
	}	
}

  //BaseAction.java

package com.wdpc.ss2h.comms;

import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.interceptor.ServletRequestAware;

	}

	public void setServletRequest(HttpServletRequest request) {

	}

	public void setSession(Map<String, Object> session) {

	}

	public HttpServletResponse getResponse() {
		return response;
	}

	public void setResponse(HttpServletResponse response) {
		this.response = response;
	}

	public HttpServletRequest getRequest() {
		return request;
	}

	public void setRequest(HttpServletRequest request) {
