hibernate 使用注解 查询和添加对象到数据库没有反应 .

在使用sring和hibernate集成的时候 我们一般可以使用两种方式去配置持久化数据层

1.配置文件

[html] view plaincopyprint?

1. <bean id="sessionFactory"  
2.     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">  
3.     <property name="dataSource" ref="dataSource"></property>  
4.     <property name="mappingResources">  
5.         <list>  
6.             <value>theone/cms/article/entity/cms.hbm.xml</value>  
7.         </list>  
8.     </property>  
9.     <property name="hibernateProperties">  
10.         <props>  
11.             <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>  
12.             <prop key="hibernate.show_sql">true</prop>  
13.         </props>  
14.     </property>  
15. </bean>  

<bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="mappingResources"><list><value>theone/cms/article/entity/cms.hbm.xml</value></list></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop><prop key="hibernate.show_sql">true</prop></props></property></bean>

这里注意 

[html] view plaincopyprint?

1. <PRE class=java name="code"><bean id="sessionFactory"  
2.         class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">  
3. <property name="mappingResources">  
4.             <list>  
5.                 <value>theone/cms/article/entity/cms.hbm.xml</value>  
6.             </list>  
7.         </property>  
8.   
9. 指定配置文件的路径  
10.   
11. 2；注解  
12. <bean id="sessionFactory"  
13.         class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"  
14.         destroy-method="destroy">  
15.         <property name="dataSource" ref="dataSource"></property>  
16.         <property name="packagesToScan" value="com.theone.entity.po" />  
17.         <property name="hibernateProperties">  
18.             <props>  
19.                 <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>  
20.                 <prop key="hibernate.show_sql">true</prop>  
21.             </props>  
22.         </property>  
23.     </bean>  
24. 注意区别上面的两个配置文件中的标示部分  
25. 还应该注意的是注解在jpa中使用  
26. /**  
27.  * @author Administrator at 2012-12-27下午07:10:22  
28.  * @Email [e-mail]  
29.  * @QQ 386115312  
30.  */  
31. @Entity  
32. @Table(name="UserInfo")  
33. public class UserInfo implements Serializable {  
34.       
35.     private static final long serialVersionUID = 1L;  
36.   
37.     @Id  
38.     @Column(name="[id]")  
39.     @GeneratedValue(strategy = GenerationType.SEQUENCE,generator="seqhilo")  
40.     @SequenceGenerator(sequenceName="userInfo_sequence", name = "seqhilo",allocationSize=1)  
41.     private long id;  
42.       
43.     @Column(name="[name]")  
44.     private String name;  
45.       
46.   
47. 这样的方式  
48. 注意了 下面是  
49. import java.io.Serializable;  
50.   
51. import javax.persistence.Column;  
52. import javax.persistence.Entity;  
53. import javax.persistence.GeneratedValue;  
54. import javax.persistence.GenerationType;  
55. import javax.persistence.Id;  
56. import javax.persistence.SequenceGenerator;  
57. import javax.persistence.Table;  
58.   
59. 注解的包，不是使用hibernate自身的注解方式！</PRE><BR>
