springMVC与springSecurity跨域实现

    	http.cors().configurationSource(configurationSource()).and().csrf().disable().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)

                .authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .logout().logoutUrl("/user/logout").addLogoutHandler((q, p, a) -> cacheService.delete(LOGIN_USER + SecurityUserUtils.getCurrentUserPhoneNum()));
    }
