Description:

Field toolbarButtonService in com.spek.common.script.ScriptController required a single bean, but 2 were found:
	- sysControlToolbarButtonService: defined in file [G:\workplace\work\common\spek-common-module\target\classes\com\spek\common\modules\control\toolbar\service\impl\SysControlToolbarButtonServiceImpl.class]
	- ISysControlToolbarButtonService: defined in file [G:\workplace\work\common\spek-common-module\target\classes\com\spek\common\modules\control\toolbar\service\ISysControlToolbarButtonService.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

Disconnected from the target VM, address: '127.0.0.1:64850', transport: 'socket'

service 接口层定义如下

public interface ISysControlToolbarService extends BaseService<SysControlToolbar> {

	void save(SysControlToolbar tbar, List<SysControlToolbarButton> buttons);

}

service实现类定义如下

@Service("sysControlToolbarService")
public class SysControlToolbarServiceImpl extends BaseServiceImpl<SysControlToolbarRepository, SysControlToolbar>
		implements ISysControlToolbarService {


}

分析问题：

这是普通的注入一个接口，目前工程只有一个实现类，为什么会爆出required a single bean, but 2 were found 问题呢？

使用的工具IDEA 2017.2.5 ，但是在eclipse中启动倒是没有这样的异常？
请问如何解决
