Getting started with hibernate

Getting started with hibernate
Quick Start

1. Download The Hibernate framework development kit

2. Write the database and Table Structure

Create database hibernate_day01;

Use hibernate_day01;

Create table 'cst _ customer '(

'Cust _ id' bigint (32) not null AUTO_INCREMENT COMMENT 'customer id (primary key )',

'Cust _ name' varchar (32) not null comment 'customer name (company name )',

'Cust _ user_id 'bigint (32) default null comment 'owner id ',

'Cust _ create_id 'bigint (32) default null comment 'creator id ',

'Cust _ source' varchar (32) default null comment 'customer information source ',

'Cust _ industry 'varchar (32) default null comment 'customer industry ',

'Cust _ level' varchar (32) default null comment 'customer level ',

'Cust _ linkman 'varchar (64) default null comment 'contacts ',

'Cust _ phone' varchar (64) default null comment 'landline phone ',

'Cust _ mobile' varchar (16) default null comment 'mobile phone ',

Primary key ('cust _ id ')

) ENGINE = InnoDB AUTO_INCREMENT = 94 default charset = utf8;

 

3. Create a WEB project and import the developed jar package

* The MySQL driver package, the required jar package for Hibernate development, and the log jar package 

 

4. Write a JavaBean file. In the future, the basic data type will not be used, and the packaging class will be used. 

5. Write the ing configuration file (CORE) and import the development constraints first. The labels are configured normally.

6. Compile the core configuration file of hibernate. The content in the file is fixed.

7. write code and use classes and Methods

If you need a jar package, leave your mailbox!
