@Repository
用于注释配置。您尝试用两种方式定义bean，xml和注释——这是一种不好的做法，可能会导致进一步的问题

尝试从xml中删除下一行：

我假设您使用
@ComponentScan
注释。

谢谢大家的支持

我已经找到了解决方案，它是通过将SpringCore版本更新到最新的it开始创建bean:）

您使用maven进行构建吗？@canillas是的，我使用mavencan您可以发布pom和依赖关系树吗？看起来您缺少一个依赖项，或者同一个库的版本不止一个（特别是检查您的spring core依赖项）。我还添加了pom.xml@canilla。我认为您存在依赖项版本问题。在项目目录中执行mvn dependency:树并检查它。你也可以发布结果。你在使用maven进行构建吗？@canillas是的，我在使用mavencan你可以发布pom和依赖树吗？看起来您缺少一个依赖项，或者同一个库的版本不止一个（特别是检查您的spring core依赖项）。我还添加了pom.xml@canilla。我认为您存在依赖项版本问题。在项目目录中执行mvn dependency:树并检查它。你也可以发布结果。
