首先创建一个maven项目
创建成功后，进行创建数据库的表
CREATE TABLE BOOK(ID INT AUTO_INCREMENT PRIMARY KEY,NAME VARCHAR(20),NUMBER int );insert into BOOK(NAME,NUMBER) VALUES(‘Java程序设计‘,10),(‘数据结构‘,10),(‘设计模式‘,10)
然后再刚刚创建的项目里创建一个类，该类名称、字段要与数据库的一样
必须注意使用的注释
package com.wbg.entity;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;@Entitypublic class Book { ???@Id ???@GeneratedValue(strategy= GenerationType.IDENTITY) ???Long id; ???String name; ???int number; ???public Book() { ???} ???public Book(Long id, String name, int number) { ???????this.id = id; ???????this.name = name; ???????this.number = number; ???} ???public Long getBook_id() { ???????return id; ???} ???public void setBook_id(Long id) { ???????this.id = id; ???} ???public String getName() { ???????return name; ???} ???public void setName(String name) { ???????this.name = name; ???} ???public int getNumber() { ???????return number; ???} ???public void setNumber(int number) { ???????this.number = number; ???}@Overridepublic String toString() { ???return "Book{" + ???????????"id=" + id + ???????????", name=‘" + name + ‘\‘‘ + ???????????", number=" + number + ???????????‘}‘;}}进行在pom.xml文件中添加依赖
<dependencies> ???????<dependency> ???????????<groupId>org.hibernate</groupId> ???????????<artifactId>hibernate-core</artifactId> ???????????<version>5.3.6.Final</version> ???????</dependency> ???????<!-- https://mvnrepository.com/artifact/org.mariadb.jdbc/mariadb-java-client --> ???????<dependency> ???????????<groupId>org.mariadb.jdbc</groupId> ???????????<artifactId>mariadb-java-client</artifactId> ???????????<version>2.3.0</version> ???????</dependency> ???????<dependency> ???????????<groupId>junit</groupId> ???????????<artifactId>junit</artifactId> ???????????<version>4.11</version> ???????????<scope>test</scope> ???????</dependency> ???</dependencies>
在resources资源文件夹目录下面创建一个hibernate.xml配置文件
<?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> ???????<!--数据库驱动--> ???????<property name="hibernate.connection.driver_class">org.mariadb.jdbc.Driver</property> ???????<!--连接--> ???????<property name="hibernate.connection.url">jdbc:mariadb://localhost:3306/stu</property> ???????<!--用户名--> ???????<property name="hibernate.connection.username">root</property> ???????<!--密码--> ???????<property name="hibernate.connection.password">123456</property> ???????<property name="hibernate.dialect">org.hibernate.dialect.MariaDB10Dialect</property> ???????<property name="hibernate.show_sql">true</property> ???????<mapping class="com.wbg.entity.Book"/> ???</session-factory></hibernate-configuration>
测试成功
package com.wbg;import com.wbg.entity.Book;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;public class test { ???public static void main(String[] args) { ???????Configuration configuration=new Configuration(); ???????Configuration configure=configuration.configure("hibernate.xml"); ???????SessionFactory sessionFactory=configuration.buildSessionFactory(); ???????Session session=sessionFactory.openSession(); ??????Book book= session.get(Book.class,2L); ???????System.out.println(book.toString()); ???}}简单使用hibernate(idea中使用)
