所有已实现的接口:
Aware, ResourceLoaderAware
直接已知子类:
ClassPathScanningCandidateComponentProvider
public class ClassPathScanningComponentProvider extends Object implements ResourceLoaderAware
A component provider that provides components from a base package. Can use the index if it is available of scans the classpath otherwise.

This implementation is based on framework 's MetadataReader facility, backed by an ASM ClassReader.

    • setResourcePattern

      public void setResourcePattern(String resourcePattern)
      Set the resource pattern to use when scanning the classpath. This value will be appended to each base package name.

    • setResourcePrefix

      public void setResourcePrefix(String resourcePrefix)
      Set the resource prefix to use when scanning the resources. This value will be appended to each base package name.

    • setResourceLoader

      public void setResourceLoader(@Nullable cn.taketoday.core.io.ResourceLoader resourceLoader)
      Set the ResourceLoader to use for resource locations. This will typically be a PatternResourceLoader implementation.

      Default is a PathMatchingResourcePatternResolver, also capable of resource pattern resolving through the ResourcePatternResolver interface.

      指定者:
      setResourceLoader 在接口中 ResourceLoaderAware
      参数:
      resourceLoader - the ResourceLoader object to be used by this object

    • getResourceLoader

      public final cn.taketoday.core.io.PatternResourceLoader getResourceLoader()
      Return the ResourceLoader that this component provider uses.

    • setMetadataReaderFactory

      public void setMetadataReaderFactory(@Nullable cn.taketoday.core.type.classreading.MetadataReaderFactory metadataReaderFactory)
      Set the MetadataReaderFactory to use.

      Default is a CachingMetadataReaderFactory for the specified resource loader.

      Call this setter method after setResourceLoader(cn.taketoday.core.io.ResourceLoader) in order for the given MetadataReaderFactory to override the default factory.

    • getMetadataReaderFactory

      public final cn.taketoday.core.type.classreading.MetadataReaderFactory getMetadataReaderFactory()
      Return the MetadataReaderFactory used by this component provider.

    • scan

      public void scan(String basePackage, MetadataReaderConsumer metadataReaderConsumer) throws IOException
      Scan the class path for candidate components.
      参数:
      basePackage - the package to check for annotated classes
      抛出:
      IOException - sneaky throw from PatternResourceLoader.getResources(String)

    • getPatternLocation

      protected String getPatternLocation(String input)

    • resolveBasePackage

      protected String resolveBasePackage(String basePackage)
      Resolve the specified base package into a pattern specification for the package search path.

      converts a "."-based package path to a "/"-based resource path.

      参数:
      basePackage - the base package as specified by the user
      返回:
      the pattern specification to be used for package searching

    • clearCache

      public void clearCache()
      Clear the local metadata cache, if any, removing all cached class metadata.
