JPA持久类扩展了来自不同JAR的另一个类
[英]JPA persistent class extending another class from different JAR
问题描述
Hoping someone can helpme with this issue as all the answers I have found do not seem to be working for me. 
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。
Under my myProj webapp I have the following 在我的myProj网络应用程序下，我有以下内容
./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;
...
}
And my application-context.xml has this (application-context.xml has sub XMLs called hibernate-context and model-context.xml, but these have always been fine) 而我的application-context.xml具有此功能（application-context.xml具有称为hibernate-context和model-context.xml的子XML，但是它们一直很好）
<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>
But on startup I get the following error in my logs 但是在启动时，我的日志中出现以下错误
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of autowired dependencies failed;

@MappedSuperclass
public abstract class CommonObject implements Serializable {
private Date createDate;
public abstract Long getId() ;
public abstract void setId(Long id);
public Date getCreateDate() {
return createDate;
}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
}
@Entity
@Table
public class UserDetails extends CommonObject {
String name;
int age;
@GeneratedValue(strategy= GenerationType.AUTO)
@Id
private Long id;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
