Hibernate constraint already exists

问题

i need help to solve this hibernate bug so every time i put a map annotation in my entity i got this error,It tries to recreate some existing constraints.

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "ID_PAYS")
public PrmPays getPrmPays() {
return this.prmPays;
}
public void setPrmPays(PrmPays prmPays) {
    this.prmPays = prmPays;
}

And this is the error !

  alter table ref_entite 
   add constraint FK4xutpn4uffubj8bfw92mmk30f 
   foreign key (id_pays) 
   references prm_pays     
Caused by: java.sql.SQLSyntaxErrorException: ORA-02275: such a referential constraint already exists in the table

here is my configuration in application.properties in spring boot

spring.datasource.driver-class-name=oracle.jdbc.OracleDriver  
hibernate.default_schema=db_default_schema_name
spring.jpa.hibernate.ddl-auto=update  
security.basic.enabled=true  


# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle=true 
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
