From source file:org.springframework.http.server.reactive.ServletHttpHandlerAdapter.java

private String getServletPath(ServletConfig config) {
    String name = config.getServletName();
    ServletRegistration registration = config.getServletContext().getServletRegistration(name);
    if (registration == null) {
        throw new IllegalStateException("ServletRegistration not found for Servlet '" + name + "'");
    }/*from w w w . j av a2s  .  co m*/

    Collection<String> mappings = registration.getMappings();
    if (mappings.size() == 1) {
        String mapping = mappings.iterator().next();
        if (mapping.equals("/")) {
            return "";
        }
        if (mapping.endsWith("/*")) {

            if (!path.isEmpty()) {
                logger.info("Found Servlet mapping '" + path + "' for Servlet '" + name + "'");
            }
            return path;
        }
    }

    throw new IllegalArgumentException(
            "Expected a single Servlet mapping: " + "either the default Servlet mapping (i.e. '/'), "
                    + "or a path based mapping (e.g. '/*', '/foo/*'). " + "Actual mappings: " + mappings
