hibernate框架搭建步骤
1.创建 web project
2.导入所需要的包antlr-2.7.7.jar
dom4j-1.6.1.jar
geronimo-jta_1.1_spec-1.1.1.jar
hibernate-commons-annotations-5.0.1.Final.jar
hibernate-core-5.0.7.Final.jar
hibernate-jpa-2.1-api-1.0.0.Final.jar
jandex-2.0.0.Final.jar
javassist-3.18.1-GA.jar
jboss-logging-3.3.0.Final.jar
//连接数据库驱动包
mysql-connector-java-5.1.7-bin.jar
3.创建数据库 准备表和实体
CREATE DATABASE customer_management CREATE TABLE `cst_customer` (
`cust_id` BIGINT(32) NOT NULL AUTO_INCREMENT COMMENT '客户编号(主键)',
`cust_name` VARCHAR(32) NOT NULL COMMENT '客户名称(公司名称)',
`cust_source` VARCHAR(32) DEFAULT NULL COMMENT '客户信息来源',
`cust_industry` VARCHAR(32) DEFAULT NULL COMMENT '客户所属行业',
`cust_level` VARCHAR(32) DEFAULT NULL COMMENT '客户级别',
`cust_linkman` VARCHAR(64) DEFAULT NULL COMMENT '联系人',
`cust_phone` VARCHAR(64) DEFAULT NULL COMMENT '固定电话',
`cust_mobile` VARCHAR(16) DEFAULT NULL COMMENT '移动电话',
PRIMARY KEY (`cust_id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
public class Customer {
private Long cust_id;
private String cust_name;
private String cust_source;
private String cust_industry;
private String cust_level;
private String cust_linkman;
private String cust_phone;
private String cust_mobile;
public Long getCust_id() {
return cust_id;
}
public void setCust_id(Long cust_id) {
this.cust_id = cust_id;
}
public String getCust_name() {
return cust_name;
}
public void setCust_name(String cust_name) {
this.cust_name = cust_name;
}
public String getCust_source() {
return cust_source;
}
public void setCust_source(String cust_source) {
this.cust_source = cust_source;
}
public String getCust_industry() {
return cust_industry;
}
public void setCust_industry(String cust_industry) {
this.cust_industry = cust_industry;
}
public String getCust_level() {
return cust_level;
}
public void setCust_level(String cust_level) {
this.cust_level = cust_level;
}
public String getCust_linkman() {
return cust_linkman;
}
public void setCust_linkman(String cust_linkman) {
this.cust_linkman = cust_linkman;
}
public String getCust_phone() {
return cust_phone;
}
public void setCust_phone(String cust_phone) {
this.cust_phone = cust_phone;
}
public String getCust_mobile() {
return cust_mobile;
}
public void setCust_mobile(String cust_mobile) {
this.cust_mobile = cust_mobile;
}
4.1导入约束
在hibernate-core-5.0.7.Final.jar中的org.hibernate 下的 hibernate-configuration-3.0.dtd<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">windows--preferences--输入cata-->XML Catalog--add--location:目录中的hibernate-mapping-3.0.dtd文件--
key type:选url--key:http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtdwindows--preferences--输入cata-->XML Catalog--add--location:目录中的hibernate-configuration-3.0.dtd文件--
key type:选url--key:http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="cn.itheima.domain.Customer" table="cst_customer">//类名 对应 表名
<id name="cust_id" column="cust_id">//主键名 对应 字段名
<generator class="native"></generator>
</id>
<property name="cust_name" column="cust_name"></property>//实体的属性名 对应 表中的字段
<property name="cust_source" column="cust_source"></property>
<property name="cust_industry" column="cust_industry"></property>
<property name="cust_level" column="cust_level"></property>
<property name="cust_linkman" column="cust_linkman"></property>
<property name="cust_phone" column="cust_phone"></property>
<property name="cust_mobile" column="cust_mobile"></property>
</class>
</hibernate-mapping>
5.写主映射文件 （连接数据库）
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!--
#hibernate.dialect org.hibernate.dialect.MySQLDialect
#hibernate.dialect org.hibernate.dialect.MySQLInnoDBDialect
#hibernate.dialect org.hibernate.dialect.MySQLMyISAMDialect
#hibernate.connection.driver_class com.mysql.jdbc.Driver
#hibernate.connection.url jdbc:mysql:///test
#hibernate.connection.username gavin
#hibernate.connection.password
-->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql:///hibernate_day01</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<!--
#hibernate.show_sql true
#hibernate.format_sql true
-->
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>
<!--
## auto schema export
#hibernate.hbm2ddl.auto create-drop
#hibernate.hbm2ddl.auto create
#hibernate.hbm2ddl.auto update
#hibernate.hbm2ddl.auto validate
-->
<property name="hibernate.hbm2ddl.auto ">update</property>
<mapping resource="cn/itheima/domain/Customer.hbm.xml"/>
</session-factory>
</hibernate-configuration>6.测试代码（junit）
@Test
//保存客户
public void fun1(){
//配置实例允许应用程序指定属性和映射文档
Configuration conf = new Configuration().configure();
//创建Session
SessionFactory sessionFactory = conf.buildSessionFactory();
//获得Session
Session session = sessionFactory.openSession();
//开启事务
Transaction tx = session.beginTransaction();
//----------------------------------------------
Customer c = new Customer();
c.setCust_name("google公司");
session.save(c);//执行保存
//----------------------------------------------
//提交事务
tx.commit();
//关闭资源
session.close();
sessionFactory.close();
}
