    public void doFilter(ServletRequest servletRequest,
                         ServletResponse servletResponse,
                         FilterChain filterChain) throws IOException, ServletException {
        log.info("TESST");

有人知道是怎么回事吗？我会非常感谢任何伸出援手的人：）

我没有正确地遵循入门页面。

我必须从spring-boot-starter-web中排除spring-boot-starter-tomcat，并包括servlet-api。
