Springboot依赖注入 Service类中使用静态变量

@Component
public class ServerHandler extends IoHandlerAdapter {
    @Autowired
    protected HealthDataService healthDataService;
    private static ServerHandler serverHandler;

    @PostConstruct
    //通过@PostConstruct实现初始化bean之前进行的操作
    public void init() {
        serverHandler = this;
        serverHandler.healthDataService = this.healthDataService;
        // 初使化时将已静态化的testService实例化
    }
    //测试调用
    public void test(){
        serverHandler.healthDataService.<你的service层方法>;
    }
}
