    • getAdviceModeAttributeName

      protected String getAdviceModeAttributeName()
      The name of the AdviceMode attribute for the annotation specified by the generic type A. The default is "mode", but subclasses may override in order to customize.

    • selectImports

      public final String[] selectImports(cn.taketoday.core.type.AnnotationMetadata importingClassMetadata)
      This implementation resolves the type of annotation from generic metadata and validates that (a) the annotation is in fact present on the importing @Configuration class and (b) that the given annotation has an advice mode attribute of type AdviceMode.

      The selectImports(AdviceMode) method is then invoked, allowing the concrete implementation to choose imports in a safe and convenient fashion.

      指定者:
      selectImports 在接口中 ImportSelector
      返回:
      the class names, or an empty array if none
      抛出:
      IllegalArgumentException - if expected annotation A is not present on the importing @Configuration class or if selectImports(AdviceMode) returns null

    • selectImports

      @Nullable protected abstract String[] selectImports(AdviceMode adviceMode)
      Determine which classes should be imported based on the given AdviceMode.

      Returning null from this method indicates that the AdviceMode could not be handled or was unknown and that an IllegalArgumentException should be thrown.

      参数:
      adviceMode - the value of the advice mode attribute for the annotation specified via generics.
      返回:
      array containing classes to import (empty array if none; null if the given AdviceMode is unknown)
