I have solved my problem
```html
<th:block th:each="frequency : ${formfrequencylist}">
<input type="checkbox"
name="cers"
th:value="${frequency.id}" />
<label th:text="${frequency.frequencyNm}"></label>
</th:block>
In my Entity I added
@ManyToMany(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH})
@JoinTable(name="form_has_frequency", joinColumns = @JoinColumn(name="form_id"), inverseJoinColumns = @JoinColumn(name="frequency_id"))
private List<FormFrequency> formFrequency = new ArrayList<FormFrequency>();
And my controller
@PreAuthorize("hasRole('ROLE_ADMIN')")
@PostMapping(value = "create/")
public String create(@ModelAttribute("regulatoryform") RegulatoryForm regulatoryform, @ModelAttribute("acthasform") ActHasForm acthasform, @RequestParam(value = "cers", required = false) int[] cers) {
System.out.println("начинаем вывод" + regulatoryform);
regulatoryform.getFormFrequency().forEach(o->System.out.println(o));
atiServiceImpl.saveRegulatoryForm(regulatoryform);
acthasform.setFormId(regulatoryform);
atiServiceImpl.saveActHasForm(acthasform);
if (cers != null) {
FormFrequency formFrequency = null;
for (int i = 0; i < cers.length; i++) {
formFrequency = new FormFrequency();
formFrequency.setId(cers[i]);
regulatoryform.getFormFrequency().add(formFrequency);
}
for (int a = 0; a < regulatoryform.getFormFrequency().size(); a++) {
FormHasFrequency formHasFrequency = new FormHasFrequency();
formHasFrequency.setFormId(regulatoryform);
formHasFrequency.setFrequencyId(regulatoryform.getFormFrequency().get(a));
atiServiceImpl.saveFormHasFrequency(formHasFrequency);
}
}
return "redirect:/regulatoryform/";
}
