Spring Security定义自定义匿名主体

Question

如何为每个匿名制作自定义唯一匿名主体而不是默认anonymousUser？

例如，请增加anonymousUser1，anonymousUser2。

我想我必须覆盖AnonymousAuthenticationFilter。

这是正确的方法吗？

@Component
public class AnonymousAuthentication extends AnonymousAuthenticationFilter {

    private AuthenticationDetailsSource<HttpServletRequest, ?> authenticationDetailsSource = new WebAuthenticationDetailsSource();

    private static int anonymSuffix = 0;

    public AnonymousAuthentication() {
        super("key");
    }

    @Override
    protected Authentication createAuthentication(HttpServletRequest request) {
            anonymSuffix++;
            AnonymousAuthenticationToken auth = new AnonymousAuthenticationToken("",
                "anonym" + anonymSuffix, AuthorityUtils.createAuthorityList("ROLE_ANONYMOUS"));
            auth.setDetails(authenticationDetailsSource.buildDetails(request));

        return auth;
    }
}
