SpringBoot中如何给静态变量static注入@Value呢?

我们都知道@value注解无法为静态变量赋值
      那么Springboot如何为静态变量赋值呢？下文笔者将一一道来，如下所示
==============================
使用set方法
       即可为静态变量赋值

@Component
public class SendMessageUtil { 
    public static String accessKeyId ;
 
    @Value("${accessKeyId}")
    public  void setAccessKeyId(String accessKeyId) {
        SendMessageUtil.accessKeyId = accessKeyId;
    }
 
    public static String accessKeySecret ;

    @Value("${accessKeySecret}")
    public  void setAccessKeySecret(String accessKeySecret) {
        SendMessageUtil.accessKeySecret = accessKeySecret;
    } 

}
