关于@Component注解下的类无法@Autowired问题

@Component
public class ComponentClass {
    @Autowired
    private JedisClient jedisClient;
    public static ComponentClass componentClass;
    @PostConstruct
    public void init(){
        componentClass = this;
        componentClass.jedisClient = this.jedisClient;
    }
}

@Component
public class XxxConfig {
	// 1
    public static XxxConfig xxxConfig ;
    @Resource
    private RedisUtil redisUtil;
	// 2
    @PostConstruct
    public void init() {
        xxxConfig = this;
        xxxConfig.redisUtil = this.redisUtil;
    }
    
    public boolean test() {
    	// 3.使用 JwtConfig.redisUtil 形式调用
        return xxxConfig.redisUtil.set("abcd", "123456", 3600);
    }    
}
