Question

加载Spring应用程序时发生此错误。我检查了相应bean的所有构造函数参数（PerformanceSchedulePoster）。这里我使用了五个构造函数参数，并且所有五个构造函数参数都是不同类型的。任何人都可以帮助我解决依赖问题。我附上了以下日志：

每当遇到此类错误时，请参阅存储库中使用的字段名称，服务层中的字段名称与实体字段名称相同。

例如，我将实体中的字段名称声明为userFullInfo 我使用并在存储库中定义为userInfo 并在服务层中调用repository.findByUserInfo_Id(); 那么你会得到这些类型的错误。

所以你只需检查实体，存储库和服务中使用的参数类型。

通过带有Ambiguous构造函数参数类型的索引3的构造函数参数表示不满意的依赖关系
