Spring Boot未满足的依赖关系

Question

我看了所有类似的问题，没有一个能帮助我，所以事情是这样的：

为了在不同的程序中重现错误，我创建了一个简单的Spring Boot程序。在尝试运行它时，我遇到了一个我无法解决的非常奇怪的错误：

    Error creating bean with name 'testController': Unsatisfied dependency expressed through field 'util'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'biUtil7' defined in class path resource [com/example/demo/configs/RootConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [com.ionos.ds.elasticsearch.connector.ES7Util] from ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader@3d4eac69]

我可能忽略了什么，但就我所见，没有错误/缺失的注释或任何东西。任何帮助都将不胜感激，谢谢。

Answer 1

您没有包含任何与您试图构建的ES7Util相关的内容。这可能会阻止你的bean创建吗？
