Java Spring@Controller、@Service和@Component中@Autowire-HttpServletRequest请求的并发性问题

由于我在httpservletrequest报头中消耗了大量数据，并在服务类的request属性中设置了大量值，我不确定这是否会导致线程安全问题，我在网上查看了自动连接httpservlet请求是否会导致线程安全问题，我的看法不一

以下是我自动连线httpservletrequest的地方

@RestController
Public class UserController {
 
 @Autowire
 HttpServletRequest httpServletRequest;

 @Autowire
 IAMService iamservice;
 
 @PostMapping("/addUser")
 public String addUser(@RequestBody UserDto userdto){
          return iamservice.addUser(userdto);
 }
}

@Service
Public Class IAMService {

 @Autowire
 HttpServletRequest httpServletRequest;

 @Autowire
 UserDao userDao;

 public String addUser(UserDto userdto){
    Long primaryKey = userDao.save(userdto,httpServletRequest.getHeader("loggedInUserId"));
    httpServletRequest.setAttribute("userPrimaryKey",primaryKey);
    return "User is added successfully";
 }
}

我们不应该@Autowire-HttpServletRequest。考虑修改以下代码以有效地使用请求对象并避免线程安全问题-< /P>

@RestController
Public class UserController {

 @Autowire
 IAMService iamservice;
 
 @PostMapping("/addUser")
 public String addUser(@RequestBody UserDto userdto, HttpServletRequest httpServletRequest){
          return iamservice.addUser(userdto, httpServletRequest);
 }
}

@Service
Public Class IAMService {

 @Autowire
 UserDao userDao;

 public String addUser(UserDto userdto, HttpServletRequest httpServletRequest){
    Long primaryKey = userDao.save(userdto,httpServletRequest.getHeader("loggedInUserId"));
    httpServletRequest.setAttribute("userPrimaryKey",primaryKey);
    return "User is added successfully";
 }
}

问题是在某些情况下，我需要HttpServletRequest，例如在spring security的userdetailsservice中，控制器建议中的异常处理程序中。我如何做到这一点？我还听说spring使用代理对象返回当前线程的servletrequest，这不是真的吗？这似乎有效
