SpringBoot静态方法注入

在工具类中注入静态实体类，以Service为例

@Component
public class DemoUtil {

    private static DemoService demoService;

    @Autowired
    public void setDemoService(DemoService demoService) {
        DemoUtil.demoService = demoService;
    }

    public static void print(){
        demoService.demo();
    }
}
