SSH中H的问题


hibernate在spring里面的配置
<!-- Hibernate配置 -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="namingStrategy">
<bean class="org.hibernate.cfg.ImprovedNamingStrategy" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
${hibernate.dialect}
</prop>
<prop key="hibernate.show_sql">
${hibernate.show_sql}
</prop>
<prop key="hibernate.format_sql">
${hibernate.format_sql}
</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.cache.provider_class">
org.hibernate.cache.EhCacheProvider
</prop>
<prop
key="hibernate.cache.provider_configuration_file_resource_path">
${hibernate.ehcache_config_file}
</prop>
</props>
</property>
<property name="packagesToScan" value="com.zw.entity.*"/>
</bean>---------------------------------------------
采用的自动更新数据库
和spring2.5的新特性
packagesToScan来映射实体类
实体类配置import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;@SuppressWarnings("serial")
@Entity
@Table(name = "t_user")
public class User implements java.io.Serializable { /**
 * 
 */
@Id
@Column(name = "id", unique = true, nullable = false)
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
/**
 * 名字
 */
@Column(name = "name", nullable = false, length = 30)
private String name;


/**
 * 名字
 */
@Column(name = "password", nullable = false, length = 30)
private String password;
下面的get/set忽略了
