这是因为
Spring
没有通过
opmanimpl
查找bean,请使用

@Autowired(required=true)
@Qualifier("operationManagerImpl")
private  OperationManager opmanimpl ;

接口
OperationManager
可能还有其他实现类。因此,Spring无法确定必须创建哪个实现。如果是这样,那么下面的内容应该会有所帮助。此外,该接口无需标记为
组件

@Autowired(必需=true)
@限定符(“operationManagerImpl”)

私人运营经理opmanimpl

堆栈跟踪清楚地表明您有多个符合自动连接条件的bean。您还没有显示您的配置,但我怀疑您正在使用组件扫描,然后还显式地定义bean。挑一个

只是好奇:标题中的“豆子”是吗?@AdrianShum,直到它被破坏。
