Spring 3.1 Hibernate 4继承的异常[无法转换为org.hibernate.mapping.RootClass]

修复此从子类中删除@Id

在MicroTask中保持

   @Id    @GeneratedValue(generator = "system-uuid")    @GenericGenerator(name = "system-uuid", strategy = "uuid")    @Column(name = "MICROTASKID")    private String microTaskId;

在子类HumanMicroTask中删除

   @Id    @Column(name = "HMTID")    private String humanMicroTaskid;
