一：添加三框架jar包

二：model层(student.java)

Java代码

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)

Java代码

<?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)

Java代码

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)

Java代码

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)

Java代码

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)

Java代码

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

Java代码

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;
