java - 当我只发送重定向时，如何在 Tomcat/Spring Boot 中关闭 JSESSIONID？

Question

当我只发送重定向时，如何阻止 Tomcat 发送 JSESSIONID cookie？我根本不访问 .getSession()。

@RequestMapping(value = "/*")
public void doUrlRequest(final HttpServletRequest request, HttpServletResponse response) {
  ...
  if (redirect != null) response.sendRedirect(redirect);

控制台

$ curl -i localhost:8080/aaa                                                                                                                                                                               HTTP/1.1 302
Set-Cookie: JSESSIONID=A38FE0B0703F4241414BD8DEF646A2BA; Path=/; HttpOnly

我试过了

request.getServletContext().setSessionTrackingModes(Collections.singleton(SessionTrackingMode.URL));

但是出错了

java.lang.IllegalStateException: The session tracking modes for context [] cannot be set whilst the context is running

我需要另一条路径的 session 。我无法为整个应用程序关闭它。我只想为这个请求处理程序关闭它。

我通过在 Controller 上注释 @Scope 标签来关闭它。

@Controller
//@Scope("session")
@ApiIgnore
public class MyUrlController implements ErrorController {
