Spring Security How can I add dynamic permission rules?

when I configure the HttpSecurity like this: When the server is running,and I can't restart it.The server need keep running,but I need to add new rules,like this: http.authorizeRequests() .antMatchers("/auth/test3").hasAuthority("test3") .antMatchers("/auth/test4").hasAuthority("test4"), How can I add the new rules when the server is running?

ps:I am currently using version 5.7.11 of SpringSecurity
