Question

我正在尝试将Spring从4.0.6升级到4.3.9版本。在这样做的过程中，我收到以下错误“ javax.persistence.TransactionRequiredException：没有实体事务可用于当前线程的EntityManager ”。整个代码工作得很早，但我只是因为库升级而得到这个错误。在我的项目中使用的Hibernate版本是4.3.7。

这是我的applicationcontext.xml

我的实体类

@SuppressWarnings("serial")
@Entity
@Table(name = "ROLES")
@NamedQueries({
      @NamedQuery(name = "RoleModuleMO.findById",        query = "SELECT rolemodule FROM RoleModuleMO rolemodule WHERE rolemodule.id =:id");    
@Proxy(lazy = false)
@EntityListeners(value = SimpleAuditListener.class)

public class RoleModuleMO implements Serializable, SimpleAuditable {
    public RoleModuleMO () {
    }

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "ROLEMODULE_ID_SQ")
    @SequenceGenerator(name = "ROLEMODULE_ID_SQ", sequenceName = "ROLEMODULE_ID_SQ")
    private Long id;

    @Column(name="ISVISIBLE", nullable = false)
    private Boolean isVisible;

    @Column(name="ISENABLED", nullable = false)
    private Boolean isEnabled;

    @Column(name="NAME", nullable = false)
    private String name;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }


    public Boolean getVisible() {
        return isVisible;
    }

    public void setVisible(Boolean visible) {
        isVisible = visible;
    }

    public Boolean getEnabled() {
        return isEnabled;
    }

    public void setEnabled(Boolean enabled) {
        isEnabled = enabled;
    }

}

我的服务类

@Transactional
public class RolesServiceImpl implements RolesService {
    @PersistenceContext
    private EntityManager em;
    private RolesDAO rolesDAO;
    private Mapper mapper;

    public RolesServiceImpl(RolesDAO rolesDAO, Mapper mapper) {
        this.rolesDAO = rolesDAO;
        this.mapper = mapper;
    }

    @Transactional
    public RoleModule saveOrUpdateModule(RoleModule vo) {
        RoleModuleMO mo = new RoleModuleMO();

        mapper.map(vo, mo);
        mo = rolesDAO.saveOrUpdateModule(mo);
        vo = mapper.map(mo, RoleModule.class);

        return vo;
    }
}

这是在春季4.0.6和升级到4.3.9后面临错误。 Spring社区是否有任何更改导致此错误，或者还有其他需要更改的内容？

提前致谢。
