登录和注册(struts2+hibernate+spring)

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;
import org.apache.struts2.interceptor.ServletResponseAware;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionSupport;
public abstract class BaseAction extends ActionSupport implements
ServletResponseAware, ServletRequestAware, SessionAware {
protected HttpServletResponse response;
protected HttpServletRequest request;
protected Map<String, Object> session;
public void setServletResponse(HttpServletResponse response) {
this.response = response;
}
public void setServletRequest(HttpServletRequest request) {
this.request = request;
}
public void setSession(Map<String, Object> session) {
this.session = session;
}
public HttpServletResponse getResponse() {
return response;
}
public void setResponse(HttpServletResponse response) {
this.response = response;
}
public HttpServletRequest getRequest() {
return request;
}
public void setRequest(HttpServletRequest request) {
this.request = request;
}
public Map getSession() {
return session;
}
}

//action层 (StudentAction.java)

Java代码
