将一个对人员增删改查的程序改成Hibernate+spring+struts方式，需要配置哪些文件？解决方法

S2SH -CRUD简单示例            


一、 准备工作
 开发环境：tomcat5+jdk6+mysql5+eclipse：eclipse-jee-helios-SR1-win32.zip.  
 struts2+Spring2.0.6+Hibernate3.1。本示例通过对一个人力资源的系统，提供基本的增加、删除、修改、查询等功能。
 lib包需要以下所示的这些包： 
     antlr-2.7.6.jar                                                                                                                                                  
     commons-collections-3.2.jar
     commons-dbcp.jar
     commons-digester-2.0.jar
     commons-fileupload-1.2.1.jar
     commons-io-1.3.2.jar
     commons-logging-1.0.4.jar
     commons-pool.jar
     dom4j-1.6.1.jar
     freemarker-2.3.16.jar
     hibernate3.jar
     javassist-3.9.0.GA.jar
     jta-1.1.jar
     log4j-1.2.15.jar
     mysql-connector-java-5.1.6-bin.jar(MySQL jar包)   
     ognl-3.0.jar    
     slf4j-api-1.5.8.jar
     slf4j-log4j12-1.5.0.jar
     spring.jar
     struts2-core-2.2.1.jar
     struts2-spring-plugin-2.2.1.jar
     xwork-core-2.2.1.jar  
     
二、建立数据库
    create database stud ;
    
    use stud ;
    create table Employee(id int(11) not null auto_increment,name varchar(255) ,address varchar(255) ,phone varchar(255) ,primary key (id)) ;
    

三、建立数据化持久层
建立Hibernate逆向工程
1、建立实体类及books.hbm.xml映射文件。
Employee.java

package com.ex.model;

public class Employee {

 private Long id ;
 private String name ;
 private String address ;
 private String phone ;
 public Long getId() {
  return id;
 }
 public void setId(Long id) {
  this.id = id;
 }
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 public String getAddress() {
  return address;
 }
 public void setAddress(String address) {
  this.address = address;
 }
 public String getPhone() {
  return phone;
 }
 public void setPhone(String phone) {
  this.phone = phone;
 }
 
 public Employee(){
  
 }
 
 public Employee(Long id, String name, String address, String phone) {
  super();
  this.id = id;
  this.name = name;
  this.address = address;
  this.phone = phone;
 }
 
 
}
2、把实体类Employee的属性映射到Employee表，生成下面的Employee.hbm.xml文件(com/ex/model/Employee.hbm.xml)：
<?xml version="1.0"?>
<!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.ex.model.Employee" table="Employee" lazy="true">
     <id name="id" type="java.lang.Long" column="id">
      <generator class="native" />
     </id>
     <property name="name" type="java.lang.String">
      <column name="name" />
     </property>
  <property name="address" type="java.lang.String">
   <column name="address" />
  </property>
  <property name="phone" type="java.lang.String">
   <column name="phone" />
  </property>
    </class>
</hibernate-mapping>


四、建立DAO层 
1、建立DAO的接口类：EmployeeDao
EmployeeDao.java
package com.ex.dao;

import java.util.List;

import com.ex.model.Employee;

public interface EmployeeDao {

 public void add(Employee employee) ;//添加新雇员
 public Employee getEmployee(Long id) ;//根据雇员ID得到雇员信息
 public List< Employee> getEmployees() ;//获取所有雇员信息
 public void delete(Long id ) ;//根据雇员ID，删除雇员
 public void saveOrUpdate(Employee employee) ;//修改或更新雇员信息
 public List< Employee> getEmployee(String name, String phone) ;//判断是否合法雇员
 
}

2、实现此接口的类文件，EmployeeDaoImpl
EmployeeDaoImpl.java
package com.ex.dao.impl;

import java.util.List;

import com.ex.dao.EmployeeDao;
import com.ex.model.Employee;
import org.hibernate.SessionFactory; 
import org.springframework.orm.hibernate3.support.HibernateDaoSupport; 

public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao {

 private SessionFactory sessionFactory ;
 
 public void setFactory(SessionFactory sessionFactory){
  
  this.sessionFactory = sessionFactory ;
 }
 public SessionFactory getFactory(){
  
  return this.sessionFactory ;
 }
 @Override
 public void add(Employee employee) {

  this.getHibernateTemplate().save( employee) ;
 }

 @Override
 public Employee getEmployee(Long id) {

  return (Employee) this.getHibernateTemplate().get(Employee.class, id) ;
 }

 @SuppressWarnings("unchecked")
 @Override
 public List<Employee> getEmployees() {
  
  return this.getHibernateTemplate().find("from Employee order by id" ) ;
 }

 @Override
 public void delete(Long id) {

  this.getHibernateTemplate().delete(this.getEmployee(id)) ;
 }

 @Override
 public void saveOrUpdate(Employee employee) {

  this.getHibernateTemplate().saveOrUpdate(employee) ;
 }

 @SuppressWarnings("unchecked")
 @Override
 public List<Employee> getEmployee(String name, String phone) {

  Object values[] ={name, phone} ;
  System.out.println("查询的结果是："+ name + "   "+ phone) ;
  return this.getHibernateTemplate().find("from Employee e where e.name=? and e.phone=? order by id", values) ;
  
 }

}


五、 建立业务逻辑层
注明：在业务逻辑层需要认真思考每个业务逻辑所能用到的持久层对象和DAO。DAO层之上是业务逻辑层，DAO类可以有很多个，但业务逻辑类应该只有一个，可以在业务逻辑类中调用各个DAO类进行操作。
1、创建服务接口类EmployeeManager
EmployeeManager.java
package com.ex.service;

import java.util.List;

import com.ex.model.Employee;

public interface EmployeeManager {

 public void addEmployee(Employee employee) ;
 public List< Employee> listEmployee() ;
 public void deleteEmployee(Long id) ;
 public void saveOrUpdate(Employee employee) ;
 public Employee getEmployee(Long id) ;
 public Employee getEmployee(String name, String phone) ;
 
 
} 

2、实现此接口类：EmployeeManagerImpl：
EmployeeManagerImpl.java
package com.ex.service.impl;

import java.util.List;

import com.ex.dao.EmployeeDao;
import com.ex.model.Employee;
import com.ex.service.EmployeeManager;

public class EmployeeManagerImpl implements EmployeeManager {

 private EmployeeDao employeeDao ;
 
 public void setEmployeeDao(EmployeeDao employeeDao){
  
  this.employeeDao = employeeDao ;
 }
 public EmployeeDao getEmployeeDao(){
  
  return this.employeeDao ;
 }
 @Override
 public void addEmployee(Employee employee) {

  this.employeeDao.add(employee) ;

 }

 @Override
 public List<Employee> listEmployee() {
  
  return this.employeeDao.getEmployees() ;
  
 }

 @Override
 public void deleteEmployee(Long id) {
  
  this.employeeDao.delete(id) ;

 }

 @Override
 public void saveOrUpdate(Employee employee) {

  this.employeeDao.saveOrUpdate(employee) ;
 }

 @Override
 public Employee getEmployee(Long id) {

  return  this.employeeDao.getEmployee(id) ;
 }

 @Override
 public Employee getEmployee(String name, String phone) {

  List< Employee> list = this.employeeDao.getEmployee(name, phone) ;
  if (list != null && list.size() >0){
   return list.get( 0 ) ;
  }else{
   return null ;
  }
 }

}


六、 创建Action类：EmployeeAction.java：

EmployeeAction.java
package com.ex.action;

import java.util.List;

import com.ex.model.Employee;
import com.ex.service.EmployeeManager;
import com.opensymphony.xwork2.ActionSupport;

public class EmployeeAction extends ActionSupport {

 private static final long serialVersionUID = 1L;

 private EmployeeManager employeeManager;
 private List<Employee> employees;
 private Employee employee;
 private Long id;
 private Long[] ids;
 private String name;
 private String phone;

 public EmployeeManager getEmployeeManager() {
  return employeeManager;
 }

 public void setEmployeeManager(EmployeeManager employeeManager) {
  this.employeeManager = employeeManager;
 }

 public List<Employee> getEmployees() {
  return employees;
 }

 public void setEmployees(List<Employee> employees) {
  this.employees = employees;
 }

 public Employee getEmployee() {
  return employee;
 }

 public void setEmployee(Employee employee) {
  this.employee = employee;
 }

 public Long getId() {
  return id;
 }

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

 public Long[] getIds() {
  return ids;
 }

 public void setIds(Long[] ids) {
  this.ids = ids;
 }

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public String getPhone() {
  return phone;
 }

 public void setPhone(String phone) {
  this.phone = phone;
 }

 // action
 public String add() {
  if (this.employeeManager.getEmployee(employee.getName(),
    employee.getPhone()) != null) {
   return INPUT;
  } else {
   this.employeeManager.addEmployee(employee);
   return SUCCESS;
  }

 }

 public String list() {
  this.employees = this.employeeManager.listEmployee();
  if (this.employees.size() > 0) {
   return SUCCESS;
  } else {
   return INPUT;
  }
 }

 public String delete() {
  if (null != this.id) {
   this.employeeManager.deleteEmployee(this.id);
  } else {
   if (ids.length > 0) {
    for (Long id : ids) {
     this.employeeManager.deleteEmployee(id);
    }
   }
  }
  if (this.employeeManager.listEmployee().size() > 0) {
   return SUCCESS;
  } else {
   return INPUT;
  }

 }

 public String saveOrUpdate() {

  this.employeeManager.saveOrUpdate(employee);
  return SUCCESS;

 }

 public String edit() {

  this.employee = this.employeeManager.getEmployee(id);
  return SUCCESS;

 }

 public String save() {
  Long id = this.employee.getId();
  employee = this.employeeManager.getEmployee(id);
  return SUCCESS;
 }

 public String update() {

  Long id = this.employee.getId();
  this.employeeManager.saveOrUpdate(employee);
  return SUCCESS;
 }

 public String login() {
  Employee emp = this.employeeManager.getEmployee(name, phone);
  List list = this.employeeManager.listEmployee();
  if (null != emp) {
   return SUCCESS;
  } else {
   if (list.size() > 0) {
    return INPUT;
   } else {
    return ERROR;
   }
  }

 }
}
