Struts2+Hibernate+Spring框架搭建（二）

二：創建數據庫和搭建Hibernate環境配置
1.首先將Hibernate的Jar包拷貝到“WEB-INF”的lib目錄下面

2.使用Oracle數據庫創建表Student

3.在src目錄下新建包“com.wl.po”，在這個包下面“Student”的類及對應的映射文件“student.hbm.xml”
Student.java

package com.wl.po;

public class Student {

	private String id;

	private String stuName;

	private String stuNo;

	private String stuSex;

	private int stuAge;

	private String stuGrade;

	public int getStuAge() {
		return stuAge;
	}

	public void setStuAge(int stuAge) {
		this.stuAge = stuAge;
	}

	public String getStuGrade() {
		return stuGrade;
	}

	public void setStuGrade(String stuGrade) {
		this.stuGrade = stuGrade;
	}

	public String getStuName() {
		return stuName;
	}

	public void setStuName(String stuName) {
		this.stuName = stuName;
	}

	public String getStuNo() {
		return stuNo;
	}

	public void setStuNo(String stuNo) {
		this.stuNo = stuNo;
	}

	public String getStuSex() {
		return stuSex;
	}

	public void setStuSex(String stuSex) {
		this.stuSex = stuSex;
	}

	public String getId() {
		return id;
	}

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

student.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 package="com.wl.po">
    <class name="Student" table="student">
        <id name="id">
           <generator class="assigned"></generator>
        </id>
        <property name="stuName" column="stuName" type="java.lang.String"></property>
        <property name="stuNo" column="stuNo" type="java.lang.String"></property>
        <property name="stuSex" column="stuSex" type="java.lang.String"></property>
        <property name="stuGrade" column="stuGrade" type="java.lang.String"></property>
        <property name="stuAge" column="stuAge" type="java.lang.Integer"></property>

    </class>
</hibernate-mapping>

4.在src下面新建包“com.wl.dao”，在下面新建接口“studentDao"

package com.wl.dao;

import com.wl.po.Student;
public interface studentDao {

	public void save(Student stu);
	public void delete(Student stu);
	public void update(Student stu);

}

5.在src下面新建包“com.wl.dao.impl”，在下面新建類“studentDaoImpl"

package com.wl.dao.impl;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.wl.dao.studentDao;
import com.wl.po.Student;

public class studentDaoImpl extends HibernateDaoSupport implements studentDao{

	public void save(Student stu){
		getHibernateTemplate().save(stu);
	}

	public void delete(Student stu){
		getHibernateTemplate().delete(stu);
	}

	public void update(Student stu){
		getHibernateTemplate().update(stu);
	}

}

6.在src下新建包”com.wl.service“，在下面新建接口"studentService"

package com.wl.service;

import com.wl.po.Student;
public interface studentService {

	public void saveStudent(Student stu);
	public void updateStudent(Student stu);
	public void deleteStudent(Student stu);
}

7.在src下新建包“com.wl.serviceImpl”，在下面新建類“serviceImpl”

package com.wl.service.impl;

import com.wl.dao.studentDao;
import com.wl.po.Student;
import com.wl.service.studentService;

public class studentServiceImpl implements studentService {

	private studentDao stuDao;

	public studentDao getStuDao() {
		return stuDao;
	}

	public void setStuDao(studentDao stuDao) {
		this.stuDao = stuDao;
	}

	public void deleteStudent(Student stu) {
		// TODO Auto-generated method stub
		stuDao.delete(stu);
	}

	public void saveStudent(Student stu) {
		// TODO Auto-generated method stub
		stuDao.save(stu);
	}

	public void updateStudent(Student stu) {
		// TODO Auto-generated method stub
		stuDao.update(stu);
	}

}

8.配置Hibernate的映射文件Hibernate.cfg.xml

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

<!DOCTYPE hibernate-configuration PUBLIC

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

    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- properties -->

        <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

        <property name="connection.url">jdbc:oracle:thin:@127.0.0.1:1521:xe</property>

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

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

        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>

        <property name="show_sql">true</property>

        <!-- mapping files -->

        <mapping resource="com/wl/po/student.hbm.xml"/>

    </session-factory>

</hibernate-configuration>
