导入jar包

导入hibernatejar包
这里写图片描述
1.创建实体类

public class UserBean {    private Integer uid;    private String name;    private String pwd;    public Integer getUid() {        return uid;    }    public void setUid(Integer uid) {        this.uid = uid;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getPwd() {        return pwd;    }    public void setPwd(String pwd) {        this.pwd = pwd;    }    @Override    public String toString() {        return "UserBean [uid=" + uid + ", name=" + name + ", pwd=" + pwd + "]";    }

 2.创建映射文件

<hibernate-mapping>    <class name="org.hopu.bean.UserBean" table="USERBEAN">        <id name="uid" type="java.lang.Integer">            <column name="UID" />            <generator class="increment" />        </id>        <property name="name" type="java.lang.String">            <column name="NAME" />        </property>        <property name="pwd" type="java.lang.String">            <column name="PWD" />        </property>    </class></hibernate-mapping>

3.创建hibernate配置文件

<hibernate-configuration><!--这里有关数据库配置的内容我们根据spring新版本的要求，写在了spring配置文件中，接下来会进行配置--> <session-factory>  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>  <property name="show_sql">true</property>  <property name="hbm2ddl.auto">update</property>  <mapping resource="org/hopu/bean/UserBean.hbm.xml"/> </session-factory></hibernate-configuration>

4.配置spring.xml文件

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">        <property name="username" value="root"></property>        <property name="password" value="密码"></property>        <property name="url" value="jdbc:mysql://localhost:3306/newtest"></property>        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>    </bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>        <property name="dataSource" ref="dataSource"></property>    </bean>

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate5.HibernateTemplate">        <property name="sessionFactory" ref="sessionFactory"></property>    </bean>

5.写一个测试类

public class Test {    public static void main(String[] args) {        ApplicationContext context =                 new ClassPathXmlApplicationContext("spring.xml");        HibernateTemplate hibernate  = (HibernateTemplate) context.getBean("hibernateTemplate");        UserBean user = hibernate.get(UserBean.class, 1);        System.out.println(user);    }}

6.得到结果UserBean [uid=1, name=admin, pwd=123]
