Java Springboot Thymeleaf MySql Hibernate试图通过ID以外的内容从数据库中提取

我有一个存储信息的数据库，它通过用户输入信息时自动输入的会话与用户关联。我试图获取信息，以便仅显示特定会话的信息。我不知道如何在后端或前端做这件事。这是我第一次在这里提问，所以如果我不够清楚，我道歉。我正在努力让我的MVP继续下去，这是我需要的最后一步。下面是我的控制器索引，目前仅通过jobDao.findAll（）显示所有作业

这是添加作业的控制器添加-

    @RequestMapping(value = "add", method = RequestMethod.POST)
    public String processJobAdd(@ModelAttribute @Valid Job newJob, HttpSession session, Errors errors, Model model,
                                HttpServletRequest request, HttpServletResponse response) {


        if (errors.hasErrors()) {
            model.addAttribute("jobTitle", "Add Job Title");
            model.addAttribute("address", "Add Address");
            model.addAttribute("jobCategory", "Select Job Category");
            model.addAttribute("jobSummary", "Add Job Summary");
            model.addAttribute("location", "Add Location");
            model.addAttribute("schedule", "Add Schedule");
            model.addAttribute("positionType", "Add Position Type");
            model.addAttribute("numOfPositions", "Add Number of Positions");
            model.addAttribute("dressCode", "Add Dress Code");
            model.addAttribute("payRate", "Add Pay Rate");
            model.addAttribute("closingDate", "Add Closing Date");
            return "job/add";
        }

        Integer name =(Integer) session.getAttribute("user_id");
        System.out.println(name +" is session name");
        newJob.setSession(name);

        jobDao.save(newJob);

        return "redirect:/job";
    }

这是我的刀

@Repository
@Transactional
public interface JobDao extends CrudRepository<Job, Integer> {

}

@存储库
@交易的
公共接口JobDao扩展了crudepository{
}

这是我在my.HTML中的表

    <table class="table table-bordered">
        <tr>
            <th></th>
            <th>Job Title</th>
            <th>Address</th>
            <th>Job Category</th>

            <th>Dress Code</th>
            <th>Pay Rate</th>
            <th>Closing Date</th>
        </tr>

        <tr th:each="job : ${jobs}">            <td><a th:href="'job/edit/' + ${job.id}" th:text="Edit"></a></td>

可以，但是。。。你的问题是什么？我如何通过会话而不是ID从数据库中提取数据？
