java - 存储库找到 3 条记录，结果列表返回 6 条记录

Question

存储库在请求发送 Controller 中找到了 3 个条目，并且列表中放置了 6 个条目

请帮助我为什么会发生这种情况，我不明白((((((

域类用户生成的唯一 ID:

public class User implements UserDetails, Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long userId;

Controller 方法:

@PreAuthorize("hasAuthority('_2_TEACHER')")
    @GetMapping("/project/{projectId}/party/create")
    public String viewTeacherCreateProjectParty(
            @PathVariable("projectId") Project project,
            Party party,
            Model model) {
        List<User> users = userService.userList(Sort.by("username"));
        model.addAttribute("project", project);
        model.addAttribute("party", party);
        model.addAttribute("users", users);
        return "teacherProjectPartyCreate";
    }

    @PreAuthorize("hasAuthority('_2_TEACHER')")
    @PostMapping("/project/{projectId}/party/create")
    public String processCreateProjectParty(
            @PathVariable("projectId") Project project,
            @Valid Party party,
            @RequestParam(value = "users") List<Long> usersIds,
            BindingResult bindingResult,
            Model model) {
        List<User> users = userService.findUsersByUserIdIn(usersIds);
        model.addAttribute("project", project);
        model.addAttribute("party", party);
        model.addAttribute("users", users);
        Long projectId = projectService.createProjectParty(project, party, users);
        return "redirect:/projects/project/" + projectId;
    }

服务方法:

public List<User> userList(Sort sort) {
    return userRepo.findAll(sort);
}

public List<User> findUsersByUserIdIn(List<Long> usersIds) {
    return userRepo.findUsersByUserIdIn(usersIds);
}

存储库中的方法:

List<User> findAll(Sort sort);

List<User> findUsersByUserIdIn(List<Long> usersIds);

我通过删除所有浏览器扩展并重新启动项目解决了该问题。我注意到 Controller 方法被执行了两次，但因为什么 - 这是一个谜
