引入依赖:
配置文件hibernate.cfg.xml：
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
hibernate.hbm2ddl.auto支持以下配置：Supported values include 'create', 'create-drop', 'create-only', 'drop', 'update', 'none' and 'validate'
SQLite方言类：

以下是测试：
实体类及配置，这里用的是lombok：
package com.whalefull.appwsd.entity;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
//部门表
@Data
//有参
@AllArgsConstructor
//无参
@NoArgsConstructor
public class BuMen {
private Integer id;
private String buMenMingCheng;
}
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
测试用例：
public static void main(String[] args) {
BuMen b = new BuMen();
b.setBuMenMingCheng( "财务" );
SessUtils.save( b );
}
工具：
package com.whalefull.appwsd.utils;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class SessUtils {
/**
* 调用Session类，执行以下过程：save → commit → close.
* @param o 实体类对象
*/
public static void save(Object o){
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session sess = sf.openSession();
Transaction transaction = sess.beginTransaction();
sess.save(o);
transaction.commit();
sess.close();
sf.close();
}
/**
* 调用Session类，执行以下过程：update → commit → close.
* @param o 实体类对象
*/
public static void update(Object o) {
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session sess = sf.openSession();
Transaction transaction = sess.beginTransaction();
sess.update(o);
transaction.commit();
sess.close();
sf.close();
}
}
测试结果：
经过反复测试，id是可以自增的
