org.hibernate.HibernateException：缺少序列或表：使用Oracle 11g的“ BPM_SEC_USER_SEQ”

Question

我遇到以下错误：  org.hibernate.HibernateException：缺少序列或表：BPM_SEC_USER_SEQ

这里我使用的是Spring 4.3.5，Hibernate 4.3.6.Final，Oracle 11g和Java 1.8。

这里BPM_SEC_USER_SEQ是我的数据库表BPM_SEC_USER提到的定序器。

这是我的.hbm.xml文件

<hibernate-mapping>

</class>

这是我的实体文件     公共类BPMSecUser扩展BaseEntity {

 private Long userId;
 private Long version=new Long(0);
 //private BPMSecRole bpmSecRole=new BPMSecRole();
 private String firstName;
 private String lastName;
 private String emailAddress;
 private String phoneNo;
 private String organization;
 private String loginName;
 private String password;
 private String confirmPassword;
 private Character active='Y';
 private Long crtBy;
 private Long modBy;
 private Calendar crtDttime;
 private Calendar modDttime;
 private Calendar lastLogin;
 private Character procErrMail='Y';
 private boolean procErr=true;
 private boolean loggedInUser;
 private String salt;
 private String currentPassword;

Setter吸气剂已删除，以提高可读性

现在，此生成器类的序列标识给了我上述错误。

此外，如果我使生成器类增加，但是我需要使用数据库中的Sequencer来增加我的user_id，以上代码将完美运行 请帮助。
