对了我们用的spring的mvc，用的批注，快点非常急

楼主看一下是不是自己的provisionSservice些了多个实现，而在使用的时候没有指定对应的实现，这类问题基本上都是这个原因，下面写了个示例自己看看。
[code="java"]public interface class ProvisionService {

}

@Component(value="provision1Service")
public class MySteelSubUserSync extends ProvisionService {
}

@Component(value="provision2Service")
public class MySteelSubUserSync extends ProvisionService {
}

@Controller
public class InterfaceController {
@Resource(name="provision2Service")
private ProvisionService provisionService;
}[/code]
controller里肯定是没有指定，自己在好好看看!
