Spring Boot 如何改变布尔值，如果检查与复选框在thymeleaf？

我正在建立每周的可用性，当一个新用户注册。我使用复选框来查看用户在一天中的哪些时间段有空。例如，如果用户在星期一直到晚上可用，则用户在星期一下检查早上和晚上。
th：field="${schedule.”““早上好，给我一个错误。th：name="${schedule.morning}”不会更改布尔值。
调度模型

@NotNull
    @NotEmpty(message = "Day of the availability is required.")
    private String day;

    @NonNull
    @Column(nullable = false)
    private boolean morning;

    @NonNull
    @Column(nullable = false)
    private boolean afternoon;

    @NonNull
    @Column(nullable = false)
    private boolean evening;

控制器

@GetMapping("/new-agent")
    public String register(Model model) {
        ScheduleHelper availability = new ScheduleHelper();
        model.addAttribute("user", new User());
        model.addAttribute("profile", new Profile());
        model.addAttribute("schedules", availability);
        model.addAttribute("languages", languages);
        return "profile_reg";
    }

    @PostMapping("/new-agent")
    public String registerNewUser(@Valid User user, BindingResult bindingResultUser,
                                  @Valid Profile profile, BindingResult bindingResult,
                                  ScheduleHelper schedules, BindingResult bindingResultSchedule,
                                  Model model, RedirectAttributes redirectAttributes) {
        if(bindingResult.hasErrors() || bindingResultUser.hasErrors() || bindingResultSchedule.hasErrors()) {
            // Show validation errors.
            logger.info("Errors registering a new user.");
            model.addAttribute("validationErrors", bindingResult.getAllErrors());
            model.addAttribute("validationErrorsUser", bindingResultUser.getAllErrors());
            model.addAttribute("validationErrorsSchedule", bindingResultSchedule.getAllErrors());
            model.addAttribute("user", user);
            model.addAttribute("profile", profile);
            model.addAttribute("schedules", schedules);
            model.addAttribute("languages", languages);
            return "profile_reg";
        } else {
            schedules.print();
            // Register new user.
            User newUser = userService.register(user);
            profile.setUser(newUser);
            Profile newProfile = profileService.register(profile);
            for(int i = 0; i < 7; i++) {
                Schedule newSchedule = schedules.getSchedule(i);
                newSchedule.setProfile(newProfile);
                scheduleService.register(newSchedule);
            }
            redirectAttributes
                    .addFlashAttribute("id", newUser.getId())
                    .addFlashAttribute("success", true);
            return "redirect:/new-agent";
        }
    }

在提交时传递列表的Helper类

@Getter
@Setter
public class ScheduleHelper {
    private List<Schedule> schedules;
    ScheduleHelper(){
        schedules = new ArrayList<>();
        String[] week = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};
        for(int i = 0; i < 7; i++) {
            schedules.add(new Schedule(week[i]));
        }
    }
    void print(){
        Schedule schedule = schedules.get(1);
        System.out.println(schedule.isMorning() + " " + schedule.isAfternoon() + " " + schedule.isEvening() + " " + schedule.getTest());
    }

    void addDay(String day){
        schedules.add(new Schedule(day));
    }
<h4 class="text-uppercase d-flex justify-content-center" style="color: #4267b2; margin-top: 10vh; margin-bottom: 3vh;">availability<br /></h4>

我希望该程序更改布尔值从假为真时，复选框被选中。

根据百里香叶的官方文件
http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#fixed-value-boolean-attributes
`th：checked被视为固定值布尔属性。像贝娄一样努力。

<input type="checkbox" class="custom-control-input" th:checked="${schedule.morning}" 
th:id="|morning-${schedule.day}|" />

要将布尔变量的值设置为true / false，如果选中了复选框，则必须用途：

<input type="checkbox" th:field="*{booleanVariableName}" />

其中booleanVariableName的setter和getter方法命名为：getBooleanVariableName和setBooleanVariableName。如果getter和setter方法的名称不同，thymeleaf将无法更新布尔值

th:checked="*{booleanVariableName}"

显示布尔变量设置的值的方法正好相反。如果复选框改变了它的状态，它不会更新变量的值
