【问题描述】：

我的 spring 控制器发送对象“部门”并且我的表单得到它并且需要检查员工检查了所有部门的多少工作保存效果很好，但是当用户编辑员工时，他需要查看已检查的工作。

为了让它工作，我需要让它像：th:checked="${jobs.contains(${job.id})}" 但我想我不能将属性值放在其他属性值中。

<div th:each="job : ${department.jobList}" class="col-md-4">
    <fieldset class="form-group">
        <label class="custom-control custom-checkbox">
            <input name="jobs" th:checked="${jobs.contains(34L)}" th:value="${job.id}" type="checkbox" class="custom-control-input"/>
            <span th:text="${job.name}" class="custom-control-description"></span>
            <span class="custom-control-indicator"></span>
        </label>
    </fieldset>
</div>

我的控制器：

// Edit employee page
@RequestMapping("/panel/{workPlaceName}/employees/{id}")
public String editEmployeesPage(Model model, HttpSession httpSession, HttpServletRequest request, @PathVariable Long id) {
    // Auto login check
    WorkPlace workPlace = new WorkPlace();
    Employee employee = new Employee();
    Object logInTemp = httpSession.getAttribute ("loggedInUser");
    if (logInTemp != null) {
        Object tempLogIn = httpSession.getAttribute ("loggedInUser");
        LogIn logIn = (LogIn) tempLogIn;
        workPlace = workPlaceService.findById(logIn.getUserName());
        model.addAttribute("workPlace",workPlace);
        employee = employeeService.findById(id);
        if(!model.containsAttribute("employee")) {
            model.addAttribute("employee", employee);
        }
    } else {
        return "redirect:/";
    }

    // END of Auto login check
    ArrayList<Long> jobs = new ArrayList<>();
    for (int i = 0; i < employee.getJobList().size(); i++) {
        jobs.add(employee.getJobList().get(i).getId());
    }
    model.addAttribute("jobs", jobs);
    model.addAttribute("action", "/panel/" + workPlace.getName() + "/employees/" + employee.getId());
    return "workplace/editEmployee";
}

好的答案是：th:checked="${jobs.contains(job.id)}"
