MyEclipse配置Hibernate框架（基础篇）

一、创建java project项目

二、项目右键Configure Facets —— Install Hibernate Facet

三、项目添加对应数据库的jar包

四、编写实体类

package com.yh;

public class Students {
    private int num;
    private String name;
    
    public Students() {
    }
    public Students(int num,String name) {
        this.num=num;
        this.name=name;
    }
    
    public int getNum() {
        return num;
    }
    public void setNum(int num) {
        this.num = num;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

五、DB Browser右键 —— new，创建数据库connection driver

六、找到数据库中对应的表右键 —— Hibernate Reverse Engineering

七、修改生成的Student.hbm.xml文件<class>的name属性为对应的实体类的路径

<hibernate-mapping>
    <class name="com.yh.Students" table="student" schema="dbo" catalog="Student">
        <id name="num" type="java.lang.Integer">
            <column name="num" />
            <generator class="assigned" />
        </id>
        <property name="name" type="java.lang.String">
            <column name="name" length="50" />
        </property>
    </class>
</hibernate-mapping>

八、修改hibernate.cfg.xml

<hibernate-configuration>

    <session-factory>
        <!-- 指定连接数据库所用的驱动 -->
        <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <!-- 指定连接数据库的url，hibernate连接的数据库名 -->
        <property name="connection.url">jdbc:sqlserver://127.0.0.1:1433;databaseName=Student</property>
        <!-- 指定连接数据库的用户名 -->
        <property name="connection.username">sa</property>
        <!-- 指定连接数据库的密码 -->
        <property name="connection.password">12345yehuan</property>
        <!-- 指定数据库方言 -->
        <property name="dialect">org.hibernate.dialect.SQLServer2008Dialect</property>
        <!-- 根据需要自动创建数据表 -->
        <property name="hbm2ddl.auto">update</property>
        <!-- 显示Hibernate持久化操作所生成的SQL -->
        <property name="show_sql">true</property>
        <!-- 将SQL脚本进行格式化后再输出 -->
        <property name="hibernate.format_sql">true</property>

        <mapping resource="mapper/Student.hbm.xml" />

    </session-factory>
</hibernate-configuration>

九、编写测试类

package com.yh;

import org.hibernate.*;
import org.hibernate.cfg.Configuration;

public class Test {
    public static void main(String[] args) {
        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
        Session session = sessionFactory.openSession();
        Transaction transaction = session.beginTransaction();
        Students stu = new Students(26,"叶欢");
        session.save(stu);
        transaction.commit();
        session.close();
        sessionFactory.close();
    }
}
