Hibernate实验三 实验内容： Hibernate组件映射 使用二级缓存 实验目的： 掌握组件映射的配置 区分值类型和实体类型 配置二级缓存 组件映射 以客户和家庭住址为例 新建component Java项目，并添加Hibernate包 创建实体类POJO //创建Address类 package component.pojo; public class Address { private String province; private String city; private String street; private String zipcode; private Customer customer; //省略setter和getter //创建Customer类 package component.pojo; public class Customer { private int id; private String name; private Address homeAddress; private Address comAddress; //省略setter和getter 映射组件Customer.hbm.xml ?xml version=1.0 encoding=UTF-8? !DOCTYPE hibernate-mapping PUBLIC -//Hibernate/Hibernate Mapping DTD 3.0//EN /hibernate-mapping-3.0.dtd hibernate-mapping class name=component.pojo.Customer table=customers lazy=”false” id name=id column=id type=int generator class=native/generator /id property name=name column=name type=string/property component name=homeAddress class=component.pojo.Address parent name=customer / property name=province column=home_province type=string / property name=city column=home_city type=string / property name=street column=home_street type=string / property name=zipcode column=home_zipcode type=string / /component component name=comAddress class=component.pojo.Address parent name=customer / property name=province column=com_province type=string / property name=city column=com_city type=string / property name=street column=com_street type=string / property name=zipcode column=com_zipcode type=string / /component /class /hibernate-mapping Hibernate配置文件Hibernate.cfg.xml hibernate-configuration session-factory property name=dialectorg.hibernate.dialect.MySQLDialect/property property name=connection.urljdbc:mysql://localhost:3306/test/property property name=connection.usernameroot/property property name=connection.password1234/property property name=connection.driver_classcom.mysql.jdbc.Driver/property property na
