Question

我的弹簧控制器发送对象＆＃34;部门＆＃34;我的表格得到了它并且需要检查员工检查所有部门的工作量保存效果很好但是当用户编辑员工时，他需要查看已经检查过的作业。

要使它工作，我需要使它像：th：checked =＆＃34; $ {jobs.contains（$ {job.id}）}＆＃34; 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>

我的控制员：

// 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）}”

我的错误是：th：checked =“$ {jobs.contains（$ {job.id}）}”

thymeleaf属性检查包含其他属性值
