Bidrectional mapping on fetch giving stackoverflow error

Hibernate ORM
1

Employee (empCode, empAddress, email)

LoginUser (userName, isLocked, empCode(fk @oneToOne))
LoginUser table contains empCode as foreign key.

Employee{
    private String empCode;
    private String empAddress;
    @OneToOne(fetch = FetchType.LAZY, mappedBy = "employee", orphanRemoval = true, cascade = CascadeType.ALL)
    private LoginUser
}

LoginUser{
    private String userName;
    private Boolean isLocked;
    @OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "empCode")
    private Employee employee;
}

When I am trying to fetch a employee object, in query in console I can see it’s fetching employee details & login details too. Then, stackoverflow error

emp.getLoginUser(),

In trace, it’s showing it’s fetching both table, then shows StackOverflow error, even If I provide fetchtype lazy

If fetchtype is provided, then why eager loading or something else?

use @JsonIgnore at Employee LoginUser column

like
Employee{
private String empCode;
private String empAddress;
@JsonIgnore
@OneToOne(fetch = FetchType.LAZY, mappedBy = “employee”, orphanRemoval = true, cascade = CascadeType.ALL)
private LoginUser
}
