Intellij Idea Hibernate 环境搭建

1. 新建hibernate项目
2. 添加mysql-connector
   • ctrl+alt+shift+s lib add mysql-connector
     
     
3. 创建实体类
   • src/entity/User.java

    ???package entity; ???public class User { ???????//hibernate 要求实体类有一个属性唯一 ???????private int uid; ???????private String username; ???????private String password; ???????private String address; ???????public int getUid() { ???????????return uid; ???????} ???????public void setUid(int uid) { ???????????this.uid = uid; ???????} ???????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 String getAddress() { ???????????return address; ???????} ???????public void setAddress(String address) { ???????????this.address = address; ???????} ???}

4. 创建src/rntity/User.hbm.xml

 ???<?xml version=‘1.0‘ encoding=‘utf-8‘?> ???<!DOCTYPE hibernate-mapping PUBLIC ???????????"-//Hibernate/Hibernate Mapping DTD 3.0//EN" ???????????"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> ???<hibernate-mapping> ???????<!-- ???????????????- 配置类和表对应 ???????????- class ???????????????- name: 实体类的全路径 ???????????????- table: 数据库表名称 ???????????- id ???????????????- name: 实体类的id属性名称 ???????????????- column: 生成表的字段名称 ???????????- generator ???????????????- class ???????????????????- native: 生成表主键id自增长 ???????????- property ???????????????- name: 属性名 ???????????????- column: 字段名 ???????--> ???????<class name="entity.User" table="t_user"> ???????????<id name="uid"> ???????????????<generator class="native"/> ???????????</id> ???????????<property name="username"/> ???????????<property name="password"/> ???????????<property name="address"/> ???????</class> ???</hibernate-mapping>

1. 配置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> ???????????<!--第一部分: 配置数据库信息--> ???????????<!--ctrl+alt+shift+s lib add mysql-connector--> ???????????<property name="connection.url"> ???????????????jdbc:mysql://127.0.0.1:3306/hibernate_test?useUnicode=true&amp;characterEncoding=utf- ???8&amp;useJDBCCompliantTimezoneShift=true&amp;useLegacyDatetimeCode=false&amp;serverTimezone=UTC ???????????</property> ???????????<property name="connection.driver_class">com.mysql.jdbc.Driver</property> ???????????<property name="connection.username">root</property> ???????????<property name="connection.password">passwd</property> ???????????<!--第二部分: 可选--> ???????????<!-- DB schema will be updated if needed --> ???????????<property name="hbm2ddl.auto">update</property> ???????????<!--输出sql语句, 并格式化--> ???????????<property name="show_sql">true</property> ???????????<property name="format_sql">true</property> ???????????<!--各个数据库的方言--> ???????????<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property> ???????????<!--第三部分: 映射文件--> ???????????<mapping resource="entity/User.hbm.xml"/> ???????</session-factory> ???</hibernate-configuration>

1. 修改Main.java

 ???import entity.User; ???import org.hibernate.*; ???import org.hibernate.cfg.Configuration; ???????????public class Main { ???????private static final SessionFactory ourSessionFactory; ???????????static { ???????????try { ???????????????//加载核心配置文件 ???????????????Configuration configuration = new Configuration(); ???????????????configuration.configure(); ???????????????????//创建SessionFactory对象, 并在数据库中把表创建出来 ???????????????????ourSessionFactory = configuration.buildSessionFactory(); ???????????} catch (Throwable ex) { ???????????????throw new ExceptionInInitializerError(ex); ???????????} ???????} ???????????public static Session getSession() throws HibernateException { ???????????//创建Session ???????????return ourSessionFactory.openSession(); ???????} ???????????public static void main(final String[] args) throws Exception { ???????????final Session session = getSession(); ???????????????try { ???????????????User user = new User(); ???????????????user.setUsername("小李"); ???????????????user.setPassword("123"); ???????????????user.setAddress("日本"); ???????????????session.save(user); ???????????????session.beginTransaction().commit(); ???????????} finally { ???????????????session.close(); ???????????} ???????} ???}

1. 执行Main.java
2. 注意事项

 ???<property name="connection.url"> ???????????????jdbc:mysql://127.0.0.1:3306/hibernate_test?useUnicode=true&amp;characterEncoding=utf-8&amp;useJDBCCompliantTimezoneShift=true&amp;useLegacyDatetimeCode=false&amp;serverTimezone=UTC ???</property> ???<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property> ???<mapping resource="entity/User.hbm.xml"/> 要放到最后
