中文解释javaorg.apache.ibatis.executor.ExecutionPlaceholder cannot be cast to java.util.List

这个错误表示试图将类型为javaorg.apache.ibatis.executor.ExecutionPlaceholder的对象转换为java.util.List类型，但是这是不可能的。这通常发生在代码中试图将一个对象强制转换为它不是的类型时。可能的原因是代码中的类型转换错误或者对象类型的错误。为了解决这个问题，需要检查代码并确保正确地使用了类型转换。

org.apache.ibatis.executor.ExecutionPlaceholder cannot be cast to java.util.List

This error occurs when you try to cast an object of type org.apache.ibatis.executor.ExecutionPlaceholder to a List. This is because ExecutionPlaceholder is not a List, but a placeholder object used by MyBatis to represent a result that has not yet been fetched from the database.

To resolve this error, you need to ensure that you are using the correct type for the object you are trying to cast. If you are expecting a List, make sure that the query you are executing returns a List of objects.

You can also check the documentation for the MyBatis API to see what types of objects are returned by different methods, and make sure that you are using the correct methods and handling the returned objects appropriately.

根据你提供的信息，这似乎是一个MyBatis插件的错误，插件试图调用一个名为"close"的方法，但在org.apache.ibatis.executor.Executor接口中找不到该方法。这可能是因为MyBatis版本与插件不兼容，或者插件中的代码有问题。建议检查插件代码和MyBatis版本，看是否需要升级或修改插件代码。
