Spring rest模板中IP地址和域名的不同场景

我有一个rest模板代码，如下所示：

  HttpHeaders headers = new HttpHeaders();
    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
    if(authentication != null) {
        Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();
        if (!authorities.contains(new SimpleGrantedAuthority(ROLE_ANONYMOUS_USER))) {
            OAuth2AuthenticationDetails details = (OAuth2AuthenticationDetails) authentication.getDetails();
            OAuth2AccessToken accessToken = tokenStore.readAccessToken(details.getTokenValue());
            headers.set(AUTHORIZATION, BEARER + accessToken);
        }
    }
  ResponseEntity<Foo> responseEntity =  restTemplate.exchange(<Domain name> + "/foo/1"
 , HttpMethod.GET, new HttpEntity(headers) , Foo.class);

HttpHeaders=newhttpheaders（）；
身份验证=SecurityContextHolder.getContext（）.getAuthentication（）；
if（身份验证！=null）{
收集
 <Domain name> + "/foo/1"
