工具类注入需要的service-优快云博客

本文介绍了一个Spring Boot应用如何通过整合Redis来缓存登录员工的详细信息，包括使用@Component注解使类被Spring扫描，@Autowired注入依赖服务，以及@PostConstruct注解初始化静态对象的方法。

/**
 *  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;
    }
    
    
    /**
