Question

希望有人可以帮助解决这个问题，因为我发现的所有答案似乎都不适合我。

在我的myProj webapp下，我有以下

./WEB=INF/lib/myproj-user.jar containing this class

@Entity
@Table(name = "user_details")
@Data
@EqualsAndHashCode(callSuper=false)
public class UserDetails extends CommonObject {
    ...
}

./WEB=INF/lib/myproj-common.jar containing this class

@MappedSuperclass
public abstract class CommonObject implements Serializable {

    private static final long serialVersionUID = -980608025624315940L;

    @Getter @Setter
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;
    ...
}

我的application-context.xml有这个（application-context.xml有子XML，叫做hibernate-context和model-context.xml，但这些一直很好）

<bean id="commonAuto" class="com.myproj.common.model.CommonObject"/>
<bean id="userDetails" class="com.myproj.user.model.UserDetails"/>

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.myproj.common.model.CommonObject</value>             
            <value>com.myproj.user.model.UserDetails</value>

但是在启动时我的日志中出现以下错误
