在看视频学hibernate，不知道最近企业用这两个方面哪个多一点，视频里说，主要用annotation，想请教请教大家
hibernate annotation
------解决方案--------------------
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
</props>
</property>
<property name="annotatedClasses">
<list>
<value>com.core.mvc.po.Student</value>
<value>com.core.mvc.po.Teacher</value>
<value>com.core.mvc.po.Comment</value>
<value>com.core.mvc.po.Department</value>
<value>com.core.mvc.po.Employee</value>
把要用大实体类写在这里
</list>
</property>
</bean>

以下是通过annotation注解的javabean，参考一下：
package db.hbm;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.UniqueConstraint;
import org.hibernate.annotations.GenericGenerator;
/**

*/
@Entity
@Table(name = "USERS", uniqueConstraints = @UniqueConstraint(columnNames = "USERNAME"))
public class Users implements java.io.Serializable {
// Fields

this.depid = depid;
this.locked = locked;
this.changepassword = changepassword;
}
/** full constructor */
public Users(String username, String fullname, String password,
String depid, String locked, String changepassword, String dutyid,
String mobile, String sex, String phonework, String phonehome,
String email, String entrust, String style, String keynum,

this.username = username;
this.fullname = fullname;
this.password = password;
this.depid = depid;

this.changepassword = changepassword;
this.dutyid = dutyid;
this.mobile = mobile;
this.sex = sex;
this.phonework = phonework;

this.email = email;
this.entrust = entrust;
this.style = style;
this.keynum=keynum;
this.keypas=keypas;
this.backup1=backup1;
this.backup2=backup2;
this.backup3=backup3;
this.backup4=backup4;
this.backup5=backup5;
}
// Property accessors
@GenericGenerator(name = "generator", strategy = "uuid")
@Id
@GeneratedValue(generator = "generator")
@Column(name = "ID", unique = true, nullable = false, length = 50)
