项目结构
News.java和NewsTest.java是另一个小项目,不用理会。
1、建立UserName.java类
package com.cfc.hibernate;
public class UserName {
private int id;
private String name;
private String password;
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return this.password;
}
public void setPassword(String password) {
this.password = password;
}
}
2、建立UserName.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.cfc.hibernate">
<class name="UserName">
<id name="id">
<generator class="native"></generator>
</id>
<property name="name" />
<property name="password" />
</class>
</hibernate-mapping>
3、建立:hibernate.cfc.xml
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- 数据库驱动 -->
<property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
<!-- 数据库名称地址 -->
<property name="hibernate.connection.url">jdbc:jtds:sqlserver://localhost:1433;DatabaseName=hibernatedemo01</property>
<!-- 数据库用户名 -->
<property name="hibernate.connection.username">sa</property>
<!-- 数据库密码 -->
<property name="hibernate.connection.password">1234</property>
<!-- 配置数据库适配器.可以直接使用相关数据库的相关特点-->
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- 根据需要自动创建数据表 -->
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- 打印sql语句到控制台 -->
<property name="hibernate.show_sql">true</property>
<!-- 对打印的Sql语句进行格式化 -->
<property name="hibernate.format_sql">true</property>
<!-- 对资源进行映射 -->
<mapping resource="com/cfc/hibernate/UserName.hbm.xml"/>
</session-factory>
</hibernate-configuration>
4、测试类:Test.java
package com.cfc.hibernate.demo;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import com.cfc.hibernate.UserName;
public class Test {
public static void main(String[] args){
try{
Configuration conf=new Configuration().configure();
SessionFactory sf=conf.buildSessionFactory();
Session sess=sf.openSession();
Transaction tx=sess.beginTransaction();
UserName user=new UserName();
user.setName("ss");
user.setPassword("22");
sess.save(user);
tx.commit();
sess.close();
System.out.print("end");
}catch(Exception e){
e.printStackTrace();
}
}
}
结果是:
总结:
1、之前的UserName.java曾用User.java。因为之前建立过,后又删了。出现了问题(总说:Caused by: java.sql.SQLException: 在关键字 'User' 附近有语法错误,后在网上查到相关资料,换名就行了)。
2、原先使用的是驱动是微软的。但出现了问题,上网找一些资料。说是微软提供的驱动有bug。于是改了用了jtds-1.2.2.jar。问题解决
