Spring + Hibernate =未知实体 [英] Spring + Hibernate = Unknown entity

问题描述

  org.springframework 
 
我试图将Spring与Hibernate结合使用Annotations， .orm.hibernate3.HibernateSystemException：未知实体：entities.Bar;嵌套异常是org.hibernate.MappingException：未知实体：entities.Bar 
  

这是我的设置.. 。

我的实体：

 包实体; 
 
 @Entity 
 public class Bar实现Serializable 
 {
 ... 
} 
  

我的Bean：

  package blah; 
 
 @Repository 
 @Service（fooService）
 @RemotingDestination（channels = {my-amf}）
 public class Foo 
 { 
保护了HibernateTemplate模板; 
 
 @Autowired 
 public void setSessionFactory（SessionFactory sessionFactory）
 {
 template = new HibernateTemplate（sessionFactory）; 
 
 
 @RemotingInclude 
 public void addBar（String name）throws DataAccessException 
 {
 Bar bar = new Bar（）; 
 bar.setName（name）; 
 template.save（bar）; 
} 
  

}

我在Spring中启用了注释：

 < context：annotation-config /> 
< context：component-scan base-package =blah/> 
 
< bean id =dataSourceclass =org.springframework.jdbc.datasource.DriverManagerDataSource> 
< property name =driverClassNamevalue =org.h2.Driver/> 
< property name =urlvalue =jdbc：h2：〜/ blahdb / blahdb/> 
< / bean> 
 
< bean id =sessionFactoryclass =org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean> 
< property name =dataSourceref =dataSource/> 
< property name =annotatedClasses> 
< list> 
< value> entities.Bar< /值> 
< / list> 
< / property> 
< property name =hibernateProperties> 
<道具> 
< prop key =hibernate.dialect> org.hibernate.dialect.H2Dialect< / prop> 
< prop key =hibernate.hbm2ddl.auto>建立< / prop> 
< /道具> 
< / property> 
< / bean> 
  

从Flex应用程序通过BlazeDS调用我的Foo.addBar方法时出现错误。 p>

我真的想避免额外的配置，看来这应该都可以。

我使用Spring 3.0.0.RC1，Hibernate Annotations 3.4.0，Tomcat 6.0.20和Java 1.6.0_15。

有什么想法？谢谢。

解决方案

尝试使用 import @ javax.persistence.Entity 和不是 org.hibernate.annotations.Entity 用于您的实体注释。

I'm trying to combine Spring with Hibernate using Annotations and I'm getting the following error:

org.springframework.orm.hibernate3.HibernateSystemException : Unknown entity: entities.Bar; nested exception is org.hibernate.MappingException: Unknown entity: entities.Bar

Here is my setup...

My Entity:

package entities;

@Entity    
public class Bar implements Serializable
{
  ...
}

My Bean:

package blah;

@Repository
@Service("fooService")
@RemotingDestination(channels = { "my-amf" })
public class Foo
{
  protected HibernateTemplate template;

  @Autowired
  public void setSessionFactory(SessionFactory sessionFactory)
  {
    template = new HibernateTemplate(sessionFactory);
  }

  @RemotingInclude
  public void addBar(String name) throws DataAccessException
  {
    Bar bar = new Bar();
    bar.setName(name);
    template.save(bar);
  }

}

I'm enabling annotations in Spring:

<context:annotation-config />
<context:component-scan base-package="blah" />

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.h2.Driver" />
    <property name="url" value="jdbc:h2:~/blahdb/blahdb" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses">
        <list>
            <value>entities.Bar</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
        </props>
    </property>
</bean>

I get the error when I call my Foo.addBar method from a Flex application through BlazeDS.

I'd really like to avoid additional configuration and it seems this should all work.

I'm using Spring 3.0.0.RC1, Hibernate Annotations 3.4.0, Tomcat 6.0.20, and Java 1.6.0_15.

Any ideas? Thanks.

解决方案

Try using import @javax.persistence.Entity and not org.hibernate.annotations.Entity for your Entity annotation.
