我不明白这种方法是如何工作的.我运行该recur方法,输出从98开始,增加,我似乎无法理解后来发生了什么.我期望的输出是:

a=98
a=99
a=99
a=100
a=100
a=101

但实际输出是:

a=98
a=99
a=100
a=101
a=100
a=99

我在本地java测试论坛中找到了这个练习.所以,任何解释都对我有用.

public  class Test  {

    public static void main(String[] args) {
        recur(98);
    }
    public static void recur(int a) {
        if (a <= 100) {
            System.out.println("a=" + a);
            recur(++a);
            System.out.println("a=" + a);
        }
    }

我喜欢使用 spring-security-saml2-service-provider 的想法 - 来自文档： https ://docs.spring.io/spring-security/reference/5.6.0-RC1/servlet/saml2/index.html spring-security-saml2-core 的它看起来少了很多样板，但是当我从 Okta 管理应用程序发送应用程序嵌入链接时，我收到 400 响应。通过调试看来

protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        AbstractSaml2AuthenticationRequest authenticationRequest = this.authenticationRequestResolver.resolve(request);
        if (authenticationRequest == null) {
            filterChain.doFilter(request, response);..}

无法解析传入的请求，但我不确定它是否相关。我的 yml 配置：
