MyEclipse配置Hibernate框架（基礎篇）

一、創建java project項目

 

二、項目右鍵Configure Facets —— Install Hibernate Facet

 

三、項目添加對應數據庫的jar包

 

四、編寫實體類

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右鍵 —— new，創建數據庫connection driver

 

六、找到數據庫中對應的表右鍵 —— Hibernate Reverse Engineering

 

七、修改生成的Student.hbm.xml文件<class>的name屬性為對應的實體類的路徑

<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>
        <!-- 指定連接數據庫所用的驅動 -->
        <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <!-- 指定連接數據庫的url，hibernate連接的數據庫名 -->
        <property name="connection.url">jdbc:sqlserver://127.0.0.1:1433;databaseName=Student</property>
        <!-- 指定連接數據庫的用戶名 -->
        <property name="connection.username">sa</property>
        <!-- 指定連接數據庫的密碼 -->
        <property name="connection.password">12345yehuan</property>
        <!-- 指定數據庫方言 -->
        <property name="dialect">org.hibernate.dialect.SQLServer2008Dialect</property>
        <!-- 根據需要自動創建數據表 -->
        <property name="hbm2ddl.auto">update</property>
        <!-- 顯示Hibernate持久化操作所生成的SQL -->
        <property name="show_sql">true</property>
        <!-- 將SQL腳本進行格式化后再輸出 -->
        <property name="hibernate.format_sql">true</property>

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

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

 

九、編寫測試類

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,"葉歡");
        session.save(stu);
        transaction.commit();
        session.close();
        sessionFactory.close();
    }
}
