我正在尝试将我的员工实体发送到视图，但是我不断收到堆栈溢出错误。

这是我通过员工模型的控制器。

public String ToShowDashboard(Model model, HttpServletRequest request) throws IOException {

    Employee employee = (Employee) this.cookieService.getStoredObject("branded", request);

    model.addAttribute("employee", employee );

    if (employee.getPosition().equals(Employee.POSITION.ADMIN)) {

        return "designers/dashboard";

    }else {return "designers/dashboard2";}

}

这是EmployeeEnity类

 @Entity
public class Employee extends DefaultEntity {


    public enum POSITION {ADMIN, NON_ADMIN}

    private String firstName;

    private String lastName;

    @Email
    private String email;

    private String password;

    private boolean activated = false;

    @Enumerated(EnumType.STRING)
    private POSITION position;

    @ManyToOne
    @JoinColumn(name = "fashion_brand_id")
    private FashionBrand fashionBrand;

    @OneToMany(mappedBy = "employee", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    private List<Task> tasks;

    private double rating;

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public FashionBrand getFashionBrand() {
        return fashionBrand;
    }

    public void setFashionBrand(FashionBrand fashionBrand) {
        this.fashionBrand = fashionBrand;
    }

    public double getRating() {
        return rating;
    }

    public void setRating(double rating) {
        this.rating = rating;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }

    public POSITION getPosition() {
        return position;
    }

    public void setPosition(POSITION position) {
        this.position = position;
    }

    public boolean isActivated() {
        return activated;
    }

    public void setActivated(boolean activated) {
        this.activated = activated;
    }
}

这是我不断得到的错误

请解决此问题的可能原因，因为错误消息不够详细。
