Данные сохраняться только после перезагрузки сервера

Всем привет. Кто может помочь почему данные сохраняются в БД только после перезагрузки сервера

У меня есть простой контроллер

@PostMapping("/saveUserAnswers")
public String saveUserAnswers(@RequestParam(name = "queryAnswers[]") Set<Answers> answers,
                              @RequestParam(name = "userID") User user) {


    Set<Answers> userAnswers = user.getAnswers();
    for (Answers a : answers) {
        userAnswers.add(a);
    }
    user.setAnswers(userAnswers);
    userRepository.save(user);
    
    return "redirect:/allQuestionnaire";
}

Два entity которые соединены связью Многие ко Многим

User

@Entity
@Table(name = "q_user")
public class User implements UserDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @Column(name = "username")
    private String username;
    @Column(name = "password")
    private String password;
    @Column(name = "active")
    private boolean active;

    @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinTable(name = "user_answers",
            joinColumns = @JoinColumn(name = "user_id"),
            inverseJoinColumns = @JoinColumn(name = "answers_id"))
    private Set<Answers> answers = new HashSet<>();

    @ElementCollection(targetClass = Role.class, fetch = FetchType.EAGER)
    @CollectionTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"))
    @Enumerated(EnumType.STRING)
    private Set<Role> roles;


    public User() {
    }


    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return isActive();
    }

    public void setUsername(String username) {
        this.username = username;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return getRoles();
    }

    public String getPassword() {
        return password;
    }

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

    public boolean isActive() {
        return active;
    }

    public void setActive(boolean active) {
        this.active = active;
    }

    public Set<Role> getRoles() {
        return roles;
    }

    public void setRoles(Set<Role> roles) {
        this.roles = roles;
    }

    public Set<Answers> getAnswers() {
        return answers;
    }

    public void setAnswers(Set<Answers> answers) {
        this.answers = answers;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        User user = (User) o;
        return active == user.active && Objects.equals(id, user.id) && Objects.equals(username, user.username) && Objects.equals(password, user.password) && Objects.equals(roles, user.roles);
    }

    @Override
    public int hashCode() {
        return Objects.hash(id, username, password, active, roles);
    }
}

Answers

package com.example.Questionnaire.entity;

import lombok.Getter;
import lombok.Setter;
import org.hibernate.Hibernate;

import javax.persistence.*;
import java.util.*;

@Getter
@Setter
@Entity
@Table(name = "answers")
public class Answers {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "name")
    private String name;

    @ManyToOne(fetch = FetchType.LAZY)
    private Question question;

    @ManyToMany(mappedBy = "answers")
    private List<User> users = new ArrayList<>();

    public Answers() {
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || Hibernate.getClass(this) != Hibernate.getClass(o)) return false;
        Answers answers = (Answers) o;
        return id != null && Objects.equals(id, answers.id);
    }

    @Override
    public int hashCode() {
        return getClass().hashCode();
    }
}

Ну и на всякий случай HTML с формой

<h1>Название опроса - ${questionnaire.name}</h1>
<form action="/saveUserAnswers" method="POST">
    <input type="hidden" value="${_csrf.token}" name="_csrf"/>
<#list qam as key,value>

    <ul class="list-group" >
        <li class="list-group-item">
           <p class="question-lead"> ${key.getName()}</p>
            <ul>
            <#list value as val>
                <li>
                    <div class="form-check">
                        <input class="form-check-input answers-input" type="checkbox"  name="queryAnswers[]" value="${val.id}"/>
                        <label class="form-check-label" style="font-size: 22px">
                            ${val.getName()}
                        </label>
                    </div>
                </li>
            </#list>

            </ul>
        </li>
    </ul>
</#list>
    <input type="hidden" name="userID" value="${user.id}">
    <input class="save_button" type="submit" value="Ответить">
</form>

После перезагрузки сервера данные добаловаться и эта проблема только в этом методе
