hibernate3、struts2 web小程序

来源：互联网发布：前端框架ajax取数据编辑：程序博客网时间：2024/05/17 09:24

第一步：建立一个web工程

第二部：使用myeclipse对struts2的支持

选择使用自己的lib包

如果使用myeclipse的依赖包不会帮你放到\WebRoot\WEB-INF\lib里

在编译的时候不会出错但是在服务器运行的时候就会找不到这些lib包而报错

接下来我们再来把Struts的依赖包放进到\WebRoot\WEB-INF\lib里面

commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-logging-1.1.1.jar
freemarker-2.3.16.jar
javassist-3.11.0.GA.jar
ognl-3.0.1.jar
struts2-core-2.2.3.1.jar
xwork-core-2.2.3.1.jar

这样我们的struts的环境就算是搭建好了

myeclipse 自动帮我生成了struts.xml 和 web.xml中需要的配置

这是在web.xml下面对struts的配置

<filter>

<filter-name >struts2</ filter-name>

<filter-class >

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

</filter-class >

</filter >

<filter-mapping >

<filter-name >struts2</ filter-name>

<url-pattern >/*</ url-pattern>

</filter-mapping >

第三步添加hibernate支持

这里我们依旧吧依赖包放到web-inf里面的lib包里面道理同上

这里是创建hibernate配置文件继续next

配置数据库连接其实也可以在后面手动配置效果是一样的接着就finish 完成配置（后面的那个next是创建一个sessionfactory类）这里我们手动写就不用创建了

这里是myeclipse自动生成的hibernate.cfg.xml

<?xml version='1.0' encoding= 'UTF-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >

<hibernate-configuration>

<session-factory >

<property name="dialect" >org.hibernate.dialect.MySQLDialect</ property>

<property name="connection.url" >jdbc:mysql://localhost:3306/hibernate</property >

<property name="connection.username" >root</ property>

<property name="connection.password" >root</ property>

<property name="connection.driver_class" >com.mysql.jdbc.Driver</ property>

</session-factory >

</hibernate-configuration>

我们要在里面加上一句这样我们就知道hibernate干了些什么

接下来我们创建hibernate与表的映射文件 Person.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>

< id name ="id" column= "id" type ="int" >

< generator class ="increment" >

</ generator>

</ id>

< property name ="username" type= "string"></ property >

< property name ="password" type= "string"></ property >

< property name ="age" type= "int"></ property >

< property name ="registerDate" type= "date"></ property >

</class >

</ hibernate-mapping>

创建一个model类 Person 没有强制性要求和表同名但是为了看起来方便还是尽量取相同的名字

package model;

import java.sql.Date;

/**

* @author HuangMin 添加一个模型类对应于数据库种的一张表

public class Person

{

private String id ;

private int age ;

private String username ;

private String password ;

private Date registerDate ;

public String getId()

{

return id ;

}

public void setId(String id)

{

this .id = id;

}

public int getAge()

{

return age ;

}

public void setAge( int age)

{

this .age = age;

}

public String getUsername()

{

return username ;

}

public void setUsername(String username)

{

this .username = username;

}

public String getPassword()

{

return password ;

}

public void setPassword(String password)

{

this .password = password;

}

public Date getRegisterDate()

{

return registerDate ;

}

public void setRegisterDate(Date registerDate)

{

this .registerDate = registerDate;

}

创建好了之后返回到hibernate.cfg.xml里添加一行让hibernate知道这个文件在哪

< mapping resource = "Person.hbm.xml" />

这样我们的基本环境就配好了

第四步编写代码

先建立一个注册页面

<%@ page language= "java" import = "java.util.*" pageEncoding ="UTF-8" %>

<%@ taglib prefix= "s" uri ="/struts-tags" %>

<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

< html>

< head>

< title> 注册 </title >

</ head>

< s:actionerror cssStyle ="color:red" />

< body>

用户名： < input type ="text" name= "username"> <br >

密    码： < input type = "password" name ="password" > < br >

年    龄： < input type = "text" name ="age" > < br>

< input type ="submit" value= "提交">

</form >

</ body>

</ html>

提交之后给savePerson.action存到数据库中然后请求转发到一个查看所有用户信息的页面

这里使用请求转发是为了你在看到用户信息的那个页面不会重复执行开始的那个存储功能

好了我们现在配置struts.xml 添加我们的action

<? xml version ="1.0" encoding= "UTF-8" ?>

<! DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd" >

< struts>

< action name ="listPerson" class= "action.PersonAction"method ="list" >

< result name ="success" > /list.jsp</ result >

</ action>

< action name ="deletePerson" class ="action.PersonAction"method= "delete">

< result name ="success" type ="redirect" > listPerson</ result >

</ action>

< action name ="getPerson" class= "action.PersonAction" method ="getPerson" >

< result name ="success" > /getPerson.jsp</ result >

</ action>

< action name ="updatePPerson" class ="action.PersonAction"

method ="getPerson" >

< result name ="success" > /updatePerson.jsp</ result >

</ action>

< action name ="updatePerson" class ="action.PersonAction"method= "update">

< result name ="success" type ="redirectAction" > listPerson</ result >

</ action>

</package >

</ struts>

跟着编写action的类

PersonAction.java

package action;

import java.sql.Date;
import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;
import model.Person;
import persistence.DBPerson;

import com.opensymphony.xwork2.ActionSupport;

public class PersonAction extends ActionSupport
{
     private String username;
     private String password;
     private int age;
     private int id;

     public String getUsername()
     {
          return username;
     }

     public void setUsername(String username)
     {
          this.username = username;
     }

     public String getPassword()
     {
          return password;
     }

     public void setPassword(String password)
     {
          this.password = password;
     }

     public int getAge()
     {
          return age;
     }

     public void setAge(int age)
     {
          this.age = age;
     }

     public int getId()
     {
          return id;
     }

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

     public String save()
     {
          Person person = new Person();
          person.setAge(age);
          person.setId(id);
          person.setPassword(password);
          person.setUsername(username);

          java.sql.Date registerDate = new java.sql.Date(
                    new java.util.Date().getTime());
          person.setRegisterDate(registerDate);
//这里在存之前先组装下对象

DBPerson.save(person);

          // int id = person.getId();
          // person = DBPerson.getPeson(id);
          // HttpServletRequest request = ServletActionContext.getRequest();
          // request.setAttribute("person", person);

          return SUCCESS;
     }

     public String list()
     {

          //这里得到结果的那个list的然后存到request里面

          List<Person> list = DBPerson.list();
          HttpServletRequest request = ServletActionContext.getRequest();
          request.setAttribute("list", list);
          return SUCCESS;
     }
//删除用户
     public String delete()
     {

          Person person = new Person();
          DBPerson.delete(person, id);
          return SUCCESS;
     }
//得到用户的详细信息
     public String getPerson()
     {
          Person person = DBPerson.getPeson(id);
          HttpServletRequest request = ServletActionContext.getRequest();
          request.setAttribute("person", person);
          return SUCCESS;
     }
//更新操作
     public String update()
     {
          Person person = DBPerson.getPeson(id);
          person.setAge(age);
          person.setPassword(password);
          DBPerson.update(person);
          return SUCCESS;
     }
//这里是对表单的验证
     public void validateSave()
     {
          if ("".equals(username) || "".equals(password))
          {
               addActionError("用户名或密码为空，请确认后提交！");
          }
     }

}

这些方法都是在BDPerson这个类里面写好的这里只是调用现在我们去写下这个类

package persistence;

import java.util.List;

import model.Person;

import org.hibernate.Query;

import org.hibernate.Session;

import org.hibernate.Transaction;

import util.HibernateUtil;

/**

* @author HuangMin 控制Person表的方法

public class DBPerson

{

/**

* 创建新的用户

public static void save(Person person)

{

Session session = HibernateUtil.openSession(); // 打开session

Transaction tx = session.beginTransaction(); // 开启事务

try

{

session.save(person);

tx.commit();

} catch (Exception e)

{

System.out.println( "添加用户时出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

/**

* 查询所有用户

@SuppressWarnings( "unchecked" )

public static List<Person> list()

{

Session session = HibernateUtil.openSession();

Transaction tx = session.beginTransaction(); // 开启事务

List<Person> list = null ;

try

{

Query query = session.createQuery( "from Person"); // hql语句，Hibernate查询语句

list = (List<Person>) query.list();

tx.commit();

} catch (Exception e)

{

System.out.println( "查询用户时出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

return list;

}

public static void delete(Person person, String id)

{

Session session = HibernateUtil.openSession();

Transaction tx = session.beginTransaction(); // 开启事务

try

{

person = (Person) session.get(Person. class , id);

session.delete(person);

tx.commit();

} catch (Exception e)

{

System.out.println( "删除用户出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

public static Person getPeson(String id)

{

Session session = HibernateUtil.openSession();

Transaction tx = session.beginTransaction(); // 开启事务

Person person = null ;

try

{

person = (Person) session.get(Person. class , id);

tx.commit();

} catch (Exception e)

{

System.out.println( "得到用户信息出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

return person;

}

public static void update(Person person)

{

Session session = HibernateUtil.openSession(); // 打卡session

Transaction tx = session.beginTransaction(); // 开启事务

try

{

session.update(person);

tx.commit();

} catch (Exception e)

{

System.out.println( "更新用户信息出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

这里我们还需要创建一个hibernate工具类让他创建sessionfactory 还有控制seesion的开关

package util;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil
{
     private static SessionFactory sessionFactory;


     //在静态代码块里面创建sessionFactory
     static
     {
          try
          {
               sessionFactory = new Configuration().configure()
                         .buildSessionFactory();
          }

          catch (Exception ex)
          {
               System.err.println("构造SessionFactory异常发生： " + ex.getMessage());
          }

     }
     //创建两个方法管理session
     public static Session openSession()
     {
          Session session = sessionFactory.openSession();

          return session;
     }

     public static void closeSession(Session session)
     {
          if (null != session)
          {
               session.close();
          }
     }
}

至此我们的java类已经全部写好了回过头去写jsp 显示页面

getPerson.jsp

<%@ page language= "java" import = "java.util.*" pageEncoding ="UTF-8" %>

<%@ taglib prefix= "s" uri ="/struts-tags" %>

现在打开你的服务器就能看到了非常简单的小程序看着张龙老师的视频之后写的因为知识有限如果有错的地方希望指正第一步：建立一个web工程

第二部：使用myeclipse对struts2的支持

选择使用自己的lib包

如果使用myeclipse的依赖包不会帮你放到\WebRoot\WEB-INF\lib里

在编译的时候不会出错但是在服务器运行的时候就会找不到这些lib包而报错

接下来我们再来把Struts的依赖包放进到\WebRoot\WEB-INF\lib里面

commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-logging-1.1.1.jar
freemarker-2.3.16.jar
javassist-3.11.0.GA.jar
ognl-3.0.1.jar
struts2-core-2.2.3.1.jar
xwork-core-2.2.3.1.jar

这样我们的struts的环境就算是搭建好了

myeclipse 自动帮我生成了struts.xml 和 web.xml中需要的配置

这是在web.xml下面对struts的配置

<filter>

<filter-name >struts2</ filter-name>

<filter-class >

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

</filter-class >

</filter >

<filter-mapping >

<filter-name >struts2</ filter-name>

<url-pattern >/*</ url-pattern>

</filter-mapping >

第三步添加hibernate支持

这里我们依旧吧依赖包放到web-inf里面的lib包里面道理同上

这里是创建hibernate配置文件继续next

配置数据库连接其实也可以在后面手动配置效果是一样的接着就finish 完成配置（后面的那个next是创建一个sessionfactory类）这里我们手动写就不用创建了

这里是myeclipse自动生成的hibernate.cfg.xml

<?xml version='1.0' encoding= 'UTF-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

<property name="connection.password" >root</ property>

<property name="connection.driver_class" >com.mysql.jdbc.Driver</ property>

</session-factory >

</hibernate-configuration>

我们要在里面加上一句这样我们就知道hibernate干了些什么

接下来我们创建hibernate与表的映射文件 Person.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" >

< property name ="password" type= "string"></ property >

< property name ="age" type= "int"></ property >

< property name ="registerDate" type= "date"></ property >

</class >

</ hibernate-mapping>

创建一个model类 Person 没有强制性要求和表同名但是为了看起来方便还是尽量取相同的名字

package model;

import java.sql.Date;

/**

* @author HuangMin 添加一个模型类对应于数据库种的一张表

public class Person

{

private String id ;

private int age ;

private String username ;

private String password ;

private Date registerDate ;

public String getId()

{

return id ;

}

public void setId(String id)

{

this .id = id;

}

public int getAge()

{

return age ;

}

public void setAge( int age)

{

this .age = age;

}

public String getUsername()

{

return username ;

}

public void setUsername(String username)

{

this .username = username;

}

public String getPassword()

{

return password ;

}

public void setPassword(String password)

{

this .password = password;

}

public Date getRegisterDate()

{

return registerDate ;

}

public void setRegisterDate(Date registerDate)

{

this .registerDate = registerDate;

}

创建好了之后返回到hibernate.cfg.xml里添加一行让hibernate知道这个文件在哪

< mapping resource = "Person.hbm.xml" />

这样我们的基本环境就配好了

第四步编写代码

先建立一个注册页面

<%@ page language= "java" import = "java.util.*" pageEncoding ="UTF-8" %>

<%@ taglib prefix= "s" uri ="/struts-tags" %>

<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

< html>

< head>

< title> 注册 </title >

</ head>

< s:actionerror cssStyle ="color:red" />

< body>

用户名： < input type ="text" name= "username"> <br >

密    码： < input type = "password" name ="password" > < br >

年    龄： < input type = "text" name ="age" > < br>

< input type ="submit" value= "提交">

</form >

</ body>

</ html>

提交之后给savePerson.action存到数据库中然后请求转发到一个查看所有用户信息的页面

这里使用请求转发是为了你在看到用户信息的那个页面不会重复执行开始的那个存储功能

好了我们现在配置struts.xml 添加我们的action

<? xml version ="1.0" encoding= "UTF-8" ?>

<! DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd" >

< struts>

< result name = "success" type = "redirect" >/result.jsp </ result>

< result name ="input" > /regitser.jsp</ result >

</ action>

< action name ="listPerson" class= "action.PersonAction"method ="list" >

< result name ="success" > /list.jsp</ result >

</ action>

< action name ="deletePerson" class ="action.PersonAction"method= "delete">

< result name ="success" type ="redirect" > listPerson</ result >

</ action>

< action name ="getPerson" class= "action.PersonAction" method ="getPerson" >

< result name ="success" > /getPerson.jsp</ result >

</ action>

< action name ="updatePPerson" class ="action.PersonAction"

method ="getPerson" >

< result name ="success" > /updatePerson.jsp</ result >

</ action>

< action name ="updatePerson" class ="action.PersonAction"method= "update">

< result name ="success" type ="redirectAction" > listPerson</ result >

</ action>

</package >

</ struts>

跟着编写action的类

PersonAction.java

          //这里得到结果的那个list的然后存到request里面

这些方法都是在BDPerson这个类里面写好的这里只是调用现在我们去写下这个类

package persistence;

这里我们还需要创建一个hibernate工具类让他创建sessionfactory 还有控制seesion的开关

至此我们的java类已经全部写好了回过头去写jsp 显示页面

现在打开你的服务器就能看到了非常简单的小程序看着张龙老师的视频之后写的因为知识有限如果有错的地方希望指正第一步：建立一个web工程

第二部：使用myeclipse对struts2的支持

选择使用自己的lib包

如果使用myeclipse的依赖包不会帮你放到\WebRoot\WEB-INF\lib里

在编译的时候不会出错但是在服务器运行的时候就会找不到这些lib包而报错

接下来我们再来把Struts的依赖包放进到\WebRoot\WEB-INF\lib里面

commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-logging-1.1.1.jar
freemarker-2.3.16.jar
javassist-3.11.0.GA.jar
ognl-3.0.1.jar
struts2-core-2.2.3.1.jar
xwork-core-2.2.3.1.jar

这样我们的struts的环境就算是搭建好了

myeclipse 自动帮我生成了struts.xml 和 web.xml中需要的配置

这是在web.xml下面对struts的配置

<filter>

<filter-name >struts2</ filter-name>

<filter-class >

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

</filter-class >

</filter >

<filter-mapping >

<filter-name >struts2</ filter-name>

<url-pattern >/*</ url-pattern>

</filter-mapping >

第三步添加hibernate支持

这里我们依旧吧依赖包放到web-inf里面的lib包里面道理同上

这里是创建hibernate配置文件继续next

配置数据库连接其实也可以在后面手动配置效果是一样的接着就finish 完成配置（后面的那个next是创建一个sessionfactory类）这里我们手动写就不用创建了

这里是myeclipse自动生成的hibernate.cfg.xml

<?xml version='1.0' encoding= 'UTF-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >

<hibernate-configuration>

<session-factory >

<property name="dialect" >org.hibernate.dialect.MySQLDialect</ property>

<property name="connection.url" >jdbc:mysql://localhost:3306/hibernate</property >

<property name="connection.username" >root</ property>

<property name="connection.password" >root</ property>

<property name="connection.driver_class" >com.mysql.jdbc.Driver</ property>

</session-factory >

</hibernate-configuration>

我们要在里面加上一句这样我们就知道hibernate干了些什么

接下来我们创建hibernate与表的映射文件 Person.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>

< id name ="id" column= "id" type ="int" >

< generator class ="increment" >

</ generator>

</ id>

< property name ="username" type= "string"></ property >

< property name ="password" type= "string"></ property >

< property name ="age" type= "int"></ property >

< property name ="registerDate" type= "date"></ property >

</class >

</ hibernate-mapping>

创建一个model类 Person 没有强制性要求和表同名但是为了看起来方便还是尽量取相同的名字

package model;

import java.sql.Date;

/**

* @author HuangMin 添加一个模型类对应于数据库种的一张表

public class Person

{

private String id ;

private int age ;

private String username ;

private String password ;

private Date registerDate ;

public String getId()

{

return id ;

}

public void setId(String id)

{

this .id = id;

}

public int getAge()

{

return age ;

}

public void setAge( int age)

{

this .age = age;

}

public String getUsername()

{

return username ;

}

public void setUsername(String username)

{

this .username = username;

}

public String getPassword()

{

return password ;

}

public void setPassword(String password)

{

this .password = password;

}

public Date getRegisterDate()

{

return registerDate ;

}

public void setRegisterDate(Date registerDate)

{

this .registerDate = registerDate;

}

创建好了之后返回到hibernate.cfg.xml里添加一行让hibernate知道这个文件在哪

< mapping resource = "Person.hbm.xml" />

这样我们的基本环境就配好了

第四步编写代码

先建立一个注册页面

<%@ page language= "java" import = "java.util.*" pageEncoding ="UTF-8" %>

<%@ taglib prefix= "s" uri ="/struts-tags" %>

<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

< html>

< head>

< title> 注册 </title >

</ head>

< s:actionerror cssStyle ="color:red" />

< body>

用户名： < input type ="text" name= "username"> <br >

密    码： < input type = "password" name ="password" > < br >

年    龄： < input type = "text" name ="age" > < br>

< input type ="submit" value= "提交">

</form >

</ body>

</ html>

提交之后给savePerson.action存到数据库中然后请求转发到一个查看所有用户信息的页面

这里使用请求转发是为了你在看到用户信息的那个页面不会重复执行开始的那个存储功能

好了我们现在配置struts.xml 添加我们的action

<? xml version ="1.0" encoding= "UTF-8" ?>

<! DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd" >

< struts>

< result name = "success" type = "redirect" >/result.jsp </ result>

< result name ="input" > /regitser.jsp</ result >

</ action>

< action name ="listPerson" class= "action.PersonAction"method ="list" >

< result name ="success" > /list.jsp</ result >

</ action>

< action name ="deletePerson" class ="action.PersonAction"method= "delete">

< result name ="success" type ="redirect" > listPerson</ result >

</ action>

< action name ="getPerson" class= "action.PersonAction" method ="getPerson" >

< result name ="success" > /getPerson.jsp</ result >

</ action>

< action name ="updatePPerson" class ="action.PersonAction"

method ="getPerson" >

< result name ="success" > /updatePerson.jsp</ result >

</ action>

< action name ="updatePerson" class ="action.PersonAction"method= "update">

< result name ="success" type ="redirectAction" > listPerson</ result >

</ action>

</package >

</ struts>

跟着编写action的类

PersonAction.java

          //这里得到结果的那个list的然后存到request里面

这些方法都是在BDPerson这个类里面写好的这里只是调用现在我们去写下这个类

package persistence;

import java.util.List;

import model.Person;

import org.hibernate.Query;

import org.hibernate.Session;

import org.hibernate.Transaction;

import util.HibernateUtil;

/**

* @author HuangMin 控制Person表的方法

public class DBPerson

{

/**

* 创建新的用户

public static void save(Person person)

{

Session session = HibernateUtil.openSession(); // 打开session

Transaction tx = session.beginTransaction(); // 开启事务

try

{

session.save(person);

tx.commit();

} catch (Exception e)

{

System.out.println( "添加用户时出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

/**

* 查询所有用户

@SuppressWarnings( "unchecked" )

public static List<Person> list()

{

Session session = HibernateUtil.openSession();

Transaction tx = session.beginTransaction(); // 开启事务

List<Person> list = null ;

try

{

Query query = session.createQuery( "from Person"); // hql语句，Hibernate查询语句

list = (List<Person>) query.list();

tx.commit();

} catch (Exception e)

{

System.out.println( "查询用户时出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

return list;

}

public static void delete(Person person, String id)

{

Session session = HibernateUtil.openSession();

Transaction tx = session.beginTransaction(); // 开启事务

try

{

person = (Person) session.get(Person. class , id);

session.delete(person);

tx.commit();

} catch (Exception e)

{

System.out.println( "删除用户出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

public static Person getPeson(String id)

{

Session session = HibernateUtil.openSession();

Transaction tx = session.beginTransaction(); // 开启事务

Person person = null ;

try

{

person = (Person) session.get(Person. class , id);

tx.commit();

} catch (Exception e)

{

System.out.println( "得到用户信息出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

return person;

}

public static void update(Person person)

{

Session session = HibernateUtil.openSession(); // 打卡session

Transaction tx = session.beginTransaction(); // 开启事务

try

{

session.update(person);

tx.commit();

} catch (Exception e)

{

System.out.println( "更新用户信息出错！" );

if (null != tx)

{

tx.rollback();

}

} finally

{

HibernateUtil.closeSession(session);

}

这里我们还需要创建一个hibernate工具类让他创建sessionfactory 还有控制seesion的开关
