要對(duì)靜態(tài)變量進(jìn)行注入
    @Resource
    private static ITecharchService techarchService;//注入為空,spring注解注入不支持靜態(tài)變量注入
    查資料找到可以這樣注入
    @Component //必須是組件，才可以用@PostConstruct
    public class DDUtils{
    @Resource
    private ITecharchService techarchService;
    private static DDUtils dd;
    @PostConstruct
    public void init() {
    dd = this;
    dd.techarchService= this.techarchService;
    }
    public void getA(){
    //調(diào)用
    dd.techarchService.getA();
    }
    }
