【问题描述】：
我正在尝试向 Spring Web 应用程序添加一些 Hibernate 功能。这是我第一次使用 Hibernate Session Factory 以某种方式独立于 Spring（我使用了 Hibernate 模板并且工作正常）。现在我得到了这些异常 org.hibernate.MappingException: Unknown entity ，尽管我认为这些组件连接良好。话不多说，让我们给你看代码：
实体类：
@Entity // javax.persistence.Entity;
@Table(name = "CreazioneV49_Users")
public class User implements Serializable {
private long id;
private String name;
private String sessionId;
@Id
@GeneratedValue
@Column(name = "USER_ID")
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
@Column(name = "USER_NAME")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Column(name = "USER_SESSIONID")
public String getSessionId() {
return sessionId;
}
public void setSessionId(String sessionId) {
this.sessionId = sessionId;
}
}
存储库类：
@Repository
@Transactional
public class DBUtil implements DBUtilInterface {
@Autowired
@Qualifier("mySessionFactory")
private SessionFactory sessionFactory;
private Session currentSession() {
return sessionFactory.getCurrentSession();
}
public void addUser(User user){
currentSession().save(user);
}
}
Spring Bean 组件：
@Component
@Scope(value = "session")
public class CreateV49 implements Serializable {
@Autowired
private DBUtilInterface dbUtil;
public DBUtilInterface getDbUtil() {
return dbUtil;
}
public void setDbUtil(DBUtil dbUtil) {
this.dbUtil = dbUtil;
}
public void persistData(){
User user = new User();
user.setName("Gigel");
user.setSessionId("1545645645646");
dbUtil.addUser(user);
System.out.println("GOOOD");
}
applicationContext.xml 的一部分
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:@//172.28.233.107:1521/SLRFORM"/>
<property name="username" value="selir"/>
<property name="password" value="selir1"/>
<property name="maxActive" value="10" />
<property name="initialSize" value="5" />
</bean>
<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="annotatedPackages">
<list>
<value>creazione.persistence</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
<bean id="txManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref local="mySessionFactory" />
</property>
</bean>
<tx:annotation-driven transaction-manager="txManager"/>
<aop:aspectj-autoproxy/>
如果在 DB 中找不到表，是否会抛出此错误？
更新：堆栈跟踪

我现在将尝试使用<property name="annotatedClasses"> 而不是包...虽然工作起来会很奇怪。
似乎使用 annotatedClasses 可以工作...用户 bean 已被识别，但我收到了一个奇怪的错误，尽管我的 ID 是自动生成的：
Hibernate: insert into CreazioneV49_Users (USER_ID, USER_NAME, USER_SESSIONID) values (null, ?, ?)
Nov 16, 2011 10:44:21 AM org.hibernate.util.JDBCExceptionReporter logExceptions
WARNING: SQL Error: 1400, SQLState: 23000
Nov 16, 2011 10:44:21 AM org.hibernate.util.JDBCExceptionReporter logExceptions
SEVERE: ORA-01400: cannot insert NULL into ("SELIR"."CREAZIONEV49_USERS"."USER_ID")
我使用的是 Oracle，因此我在 User bean 中的 ID 中添加了一个序列生成器，但没有成功：
@Id
@SequenceGenerator(name = "my-creazioneV49Seq", sequenceName = "creazioneV49Seq")
@GeneratedValue(strategy = GenerationType.AUTO, generator = "my-creazioneV49Seq")
@Column(name = "USER_ID")
public long getId() {
return id;
}
已解决：升级到 HIBERNATE 3.6.8 并将方言更改为 ORACLE！
【问题讨论】：
-
您的
persistence.xml中有什么内容？ -
@CodeBrickie 我没有。如您所见，我只使用注释。
-
“有它需要的一切”这个声明太强了...再检查一下！
-
你有没有尝试过使用
test.package.Foo test.package.Bar 列表> -
你能粘贴完整的堆栈跟踪吗？
