Классы моделей Клиенты: в этом классе я не уверен насчет аннотаций каскадных таблиц и таблиц соединений, используя эти аннотации сущностей I ' m может создавать таблицы, но не может вставлять значения в таблицу.

import java.util.Set;

Проблема в том, что таблицу cust_role пружина пытается создать из-за @JoinTable в вашей модели клиента.

@JoinTable(
    name="cust_role", 
    joinColumns = @JoinColumn(name="cid"),
    inverseJoinColumns = @JoinColumn(name="role_id"))

У вас есть ; на ваше имя @JoinColumn s.

На самом деле информация не нужна. Это также должно работать:

@NoArgsConstructor
@Entity
public class Role {
    @Id
    @GeneratedValue
    private int role_id;
    private String role;

    //setters and Getters
}
@Entity
public class Customers {

    @Id
    private int cid;
    private String cname;
    private String cpassword;
    private String cemail;
    @OneToMany(cascade=CascadeType.ALL, fetch =FetchType.EAGER)
    @JoinTable
    private Set<Role> role;

    //getters and Setters
}

Или даже проще без аннотации @JoinTable. Просто добавьте поле «Клиенты» в свою роль и добавьте к нему аннотацию @ManyToOne:

@NoArgsConstructor
@Entity
public class Role {
    @Id
    @GeneratedValue
    private int role_id;
    private String role;

    @ManyToOne
    private Customers customer;

    //setters and Getters
}

и добавьте значение mappedBy в аннотацию @OneToMany. Оно должно иметь то же имя, что и ваше поле в классе партнера, здесь customer

@Entity
public class Customers {

    @Id
    private int cid;
    private String cname;
    private String cpassword;
    private String cemail;
    @OneToMany(mappedBy = "customer")
    private Set<Role> role;

    //getters and Setters
}

Я рекомендую прочитать сообщения Влада о сопоставлении с Hibernate:
