1 导入所需的jar包
1 导入hibernate必须的jar包
2 导入驱动包
2 创建数据库,准备表,实体
1 创建hibernate数据库
CREATE DATABASE hibernate;
2 创建cst_customer表
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;
3 Customer实体
package www.test.domain; public class Customer { /* * 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; */ 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; } @Override public String toString() { return "Customer [cust_id=" + cust_id + ", cust_name=" + cust_name + "]"; } }
3 书写orm元数据(对象与表的映射配置文件)
<?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"> <!-- 配置表与实体的关系 --> <hibernate-mapping> <class name="www.test.domain.Customer" table="cst_customer"> <id name="cust_id" column="cust_id"> <generator class="native"></generator> </id> <property name="cust_name" column="cust_name"></property> <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>
1 导入约束
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
2 实体
package www.test.domain; public class Customer { /* * 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; */ 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; } @Override public String toString() { return "Customer [cust_id=" + cust_id + ", cust_name=" + cust_name + "]"; } }
3 orm元数据
<!-- 配置表与实体的关系 --> <hibernate-mapping> <class name="www.test.domain.Customer" table="cst_customer"> <id name="cust_id" column="cust_id"> <generator class="native"></generator> </id> <property name="cust_name" column="cust_name"></property> <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>
4.书写主配置文件
<?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> <!-- /// 表示连接本机 --> <property name="hibernate.connection.url">jdbc:mysql:///hibernate</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLMyISAMDialect</property> <!-- #hibernate.show_sql true //打印生成的sql #hibernate.format_sql true //格式化sql 不格式都会在一行 --> <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="www/test/domain/Customer.hbm.xml"/> </session-factory> </hibernate-configuration>
1 第一部分
<!-- #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> <!-- /// 表示连接本机 --> <property name="hibernate.connection.url">jdbc:mysql:///hibernate</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLMyISAMDialect</property>
2 第二部分
<!-- #hibernate.show_sql true //打印生成的sql #hibernate.format_sql true //格式化sql 不格式都会在一行 --> <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>
3 第三部分
<mapping resource="www/test/domain/Customer.hbm.xml"/>
5.书写代码测试
package www.test.a_hello; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; import org.junit.Test; import www.test.domain.Customer; // 测试hibernate 框架 public class Demo { @Test //保存客户 public void fun1(){ Configuration conf = new Configuration().configure(); SessionFactory sessionFactory = conf.buildSessionFactory(); Session session = sessionFactory.openSession(); Transaction tx = session.beginTransaction(); //----------------- Customer customer = new Customer(); customer.setCust_name("百度公司"); session.save(customer); //执行保存 //-------------------- tx.commit(); session.close(); sessionFactory.close(); } }
