Restful:如何在Service类中访问Httpsession？

public void serviceMethod(HttpServletRequest request) {
    HttpSession session = request.getSession();
    // 使用session对象进行操作
}

public class HttpSessionContext {
    private static final ThreadLocal<HttpSession> sessionThreadLocal = new ThreadLocal<>();

    public static void setSession(HttpSession session) {
        sessionThreadLocal.set(session);
    }

    public static HttpSession getSession() {
        return sessionThreadLocal.get();
    }

    public static void removeSession() {
        sessionThreadLocal.remove();
    }
}

@RequestMapping("/test")
public void test(HttpSession session) {
    HttpSessionContext.setSession(session);
    // 调用Service类中的方法
}

public void serviceMethod() {
    HttpSession session = HttpSessionContext.getSession();
    // 使用session对象进行操作
}

@Autowired
private HttpSession httpSession;

public void serviceMethod() {
    // 使用httpSession对象进行操作
}
