小编Tei*_*ifi的帖子

抱歉英语不好.我得到了我的项目spring-boot 1.1.8,Encountered Exception No CurrentSessionContext configured,然后我做了一些搜索,添加属性<property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>可以解决这个问题,但是

如何使用java类配置此属性？

更新:我改为Hibernate4.x方式来定义SessionFactory但仍然遇到同样的错误,请帮忙!

使用java 1.8和speing boot 1.1.8

这是我的pom.xml

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
        <main.basedir>${basedir}/../..</main.basedir>
        <m2eclipse.wtp.contextRoot>../</m2eclipse.wtp.contextRoot>
    </properties>

这是我的服务和控制器

@AutoWried
SessionFactory sessionFactory;

@Service
@Transactional
public class UserServiceImpl implements UserService { …

当前的spring-mvc webapp (也见于另一个primefaces webapp) webapplication目录结构:

webapp
|
|_src
|
|_WebContent
  |
  |__WEB-INF
  |
  |__META-INF
     |
     |__MANIFEST.MF

始终MANIFEST.MF在META-INF目录中查看和归档.有时候,如果删除它们,似乎没有其他事情会发生.它们的作用是什么？

~#:cat MANIFEST.MF

Manifest-Version: 1.0
Class-Path:

class A implements Serializable{
    private static final long serialVersionUID = 1L;
    @Id
    Integer id;
    ...
    // constructor getter and setter 
}

@Entity
class B extends A{
    private static final long serialVersionUID = 1L;
    @Column
    String name;
    @Column
    String age;
    ...
    //constructors, getters and setters
}

如上所示,类A从类扩展B,B应该具有标识符id继承A.但我得到了No identifier specified for entity: com.d.e.B

我错过了什么？提前致谢.
