org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider

org.springframework.context.annotation.ClassPathBeanDefinitionScanner

io.microsphere.spring.context.annotation.ExposingClassPathBeanDefinitionScanner

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ResourceLoaderAware, org.springframework.core.env.EnvironmentCapable

public class ExposingClassPathBeanDefinitionScanner
extends org.springframework.context.annotation.ClassPathBeanDefinitionScanner

A extension class of ClassPathBeanDefinitionScanner to expose some methods:

• ClassPathBeanDefinitionScanner.doScan(String...)
• ClassPathBeanDefinitionScanner.checkCandidate(String, BeanDefinition)

ExposingClassPathBeanDefinitionScanner also supports the features from BeanDefinitionRegistry and SingletonBeanRegistry

Example Usage

     // Create an instance with a BeanDefinitionRegistry
     ExposingClassPathBeanDefinitionScanner scanner = new ExposingClassPathBeanDefinitionScanner(registry, useDefaultFilters, environment, resourceLoader);

     // Perform a scan to detect and register beans
     Set<BeanDefinitionHolder> beanDefinitions = scanner.doScan("com.example.package");

     // Register a custom bean definition
     scanner.registerBeanDefinition("myBean", myBeanDefinition);

     // Register a singleton instance
     scanner.registerSingleton("mySingleton", new MySingleton());
 

Since:

1.0.0
