Hibernate中使用类映射文件创建数据库表.docx

1.加入Hibernate 3支持；2.定义实体类；3.创建实体类的映射文件；4.通过配置文件hibernate.cfg.xml将映射文件加入到Hibernate中；5.使用SchemaExport类创建数据库。6.创建序列实现自增字段：id name=id type=java.lang.Longcolumn name=ID precision=22 scale=0 /generator class=sequenceparam name=sequenceSEQ_HB_USER_ID/param/generator/idhibernate.cfg.xml:程序代码?xml version=1.0 encoding=UTF-8?!DOCTYPE hibernate-configuration PUBLIC-//Hibernate/Hibernate Configuration DTD 3.0//EN/hibernate-configuration-3.0.dtd!-- Generated by MyEclipse Hibernate Tools. --hibernate-configurationsession-factoryproperty name=connection.usernamescott/propertyproperty name=connection.urljdbc:oracle:thin:@:1521:MGC/propertyproperty name=dialectorg.hibernate.dialect.Oracle9Dialect/propertyproperty name=fileMGC/propertyproperty name=connection.passwordtiger/propertyproperty name=connection.driver_classoracle.jdbc.driver.OracleDriver/propertymapping resource=cn/edu/ahau/mgc/hibernate/simple/pojo/User.hbm.xml //session-factory/hibernate-configurationUser.java:程序代码package .ahau.mgc.hibernate.simple.pojo;public class User {private int id;private String userName;private String password;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}User.hbm.xml:程序代码?xml version=1.0 encoding=utf-8?!DOCTYPE hibernate-mapping PUBLIC -//Hibernate/Hibernate Mapping DTD 3.0//EN/hibernate-mapping-3.0.dtd!-- Mapping file autogenerated by MyEclipse Persistence Tools--hibernate-mappingclass name=.ahau.mgc.hibernate.simple.pojo.User table=HB_USER schema=SCOTTid name=id type=java.lang.Longcolumn name=ID precision=22 scale=0 /generator class=sequenceparam name=sequenceSEQ_HB_USER_ID/param/generator/idproperty name=username type=java.lang.Stringcolumn name=USERNAME length=10 not-null=true //propertyproperty name=password type=java.lang.Stringcolumn name=P
