ClassPathScanningCandidateComponentProvider

// 关闭默认过滤器
ClassPathScanningCandidateComponentProvider provider = new ClassPathScanningCandidateComponentProvider(false);

provider.addIncludeFilter(new AnnotationTypeFilter(Entity.class));
// 扫描指定classpath或者包路径下的bean定义
Set<BeanDefinition> beanDefinitions = provider.findCandidateComponents(basePackage)
