springboot 静态方法中使用@Autowired注入配置和Bean

@Component
public class StructUtil {
    private static RestTemplate restTemplate;
  private static String API_KEY;
  // 通过重写set注入
    @Autowired
    public void setRestTemplate(RestTemplate restTemplate) {
        StructUtil.restTemplate = restTemplate;
    }
    @Value("${tripartite.setting.apiKey}")
    public void setApiKey(String apiKey) {
        StructUtil.API_KEY = apiKey;
    }
    public static void getStruct(){
      System.out.println(API_KEY);
      System.out.println(restTemplate);
    }
}

@Component
public class WeChatContant {
    @Autowired
    private RestTemplate restTemplate2;
    private static RestTemplate restTemplate;
    @PostConstruct
    public void init(){
        restTemplate= restTemplate2;
    }
    public static JSONObject doGerStr(String url){
       System.out.println(restTemplate);
       return null;
    }
}
