How to map a legacy database table with mismanaged attribute names

Question

I'm working on a legacy database for which I have generated the following entity classes:

Business entity

@Entity
public class Business { ... }

Frontuser entity

@Entity
public class Frontuser { ... }

Review entity

@Entity
@Table(name="review")
public class Review {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(unique=true, nullable=false)
    private int id;

    @Column(nullable=false)
    private int businesshoteltravelId;

    @Column(name = "frontuser_id", nullable=false)
    private int frontuser_id;

    @Column(name = "business_id", nullable=false)
    private int business_id;

    @ManyToOne
    @JoinColumn(name="frontuserId", nullable=false)
    private Frontuser frontuser;

    @ManyToOne
    @JoinColumn(name="businessId", nullable=false)
    private Business business;
}

As seen, the columns frontuser_id and business_id are foreign key columns to other tables. Columns frontuserId and businessId are an abomination (from a naming convention perspective).

It is worth noting that the review table actually contains the four columns frontuser_id, business_id, frontuserId and businessId.

With these entity declarations, my application fails to start with the following exception:

org.springframework.beans.factory.BeanCreationException:
  Error creating bean with name 'entityManagerFactory'
    Table [review] contains physical column name [business_id] referred to by multiple physical column names: [businessId], [business_id]

I am not sure why this error occurs, given that I have explicitly named table columns in the entity class declaration.

How I can map these attributes with JPA?
