工具类注入需要的service

/**
 *  从redis获取信息
 * @author yy

 */

@Component//关键一：添加此注解才能被spring扫描到
public class CacheUtil {

    private static Logger logger = LoggerFactory.getLogger(CacheUtil.class);

    @Autowired
    private JJWTUtils jwt;  //关键二：添加需要的服务类
    public static CacheUtil cacheUtil; //关键三：声明一个当前类的静态对象

    @PostConstruct  //关键四：通过@PostConstruct注解实现注入
    public void init() {
        cacheUtil = this;
        //cacheUtil.jwtUtils =  this.jwtUtils;
    }
