ORA-02261: 表中已存在这样的唯一关键字或主键

create table EM_USER.EM_CONT_UPDATE_LOG (ECUL_ID varchar2(32 char) not null unique,
 ECUL_CONT_ID varchar2(32 char), ECUL_MODIFY_DATE timestamp, ECUL_MODIFY_ID varchar2(32 char),
  ECUL_MODIFY_REAL_NAME varchar2(40 char), ECUL_NEW_CONT_NO varchar2(32 char),
  ECUL_OLD_CONT_NO varchar2(32 char), primary key (ECUL_ID))

hibernate逆向生成的实体类主键含有unique = true，生成数据库会报错。。

SEVERE: ORA-02261: 表中已存在这样的唯一关键字或主键

@Column(name = "EAD_ID", unique = true, nullable = false, length = 32)

 去掉unique = true 后ok
