Example 1 with ScopeMetadataResolver

use of org.springframework.context.annotation.ScopeMetadataResolver in project spring-framework by spring-projects.

the class ClassPathBeanDefinitionScannerJsr330ScopeIntegrationTests method createContext.

Example 2 with ScopeMetadataResolver

use of org.springframework.context.annotation.ScopeMetadataResolver in project spring-framework by spring-projects.

the class AnnotationConfigWebApplicationContext method loadBeanDefinitions.

/**
 * Register a {@link org.springframework.beans.factory.config.BeanDefinition} for
 * any classes specified by {@link #register(Class...)} and scan any packages
 * specified by {@link #scan(String...)}.
 * <p>For any values specified by {@link #setConfigLocation(String)} or
 * {@link #setConfigLocations(String[])}, attempt first to load each location as a
 * class, registering a {@code BeanDefinition} if class loading is successful,
 * and if class loading fails (i.e. a {@code ClassNotFoundException} is raised),
 * assume the value is a package and attempt to scan it for component classes.
 * <p>Enables the default set of annotation configuration post processors, such that
 * {@code @Autowired}, {@code @Required}, and associated annotations can be used.
 * <p>Configuration class bean definitions are registered with generated bean
 * definition names unless the {@code value} attribute is provided to the stereotype
 * annotation.
 * @param beanFactory the bean factory to load bean definitions into
 * @see #register(Class...)
 * @see #scan(String...)
 * @see #setConfigLocation(String)
 * @see #setConfigLocations(String[])
 * @see AnnotatedBeanDefinitionReader
 * @see ClassPathBeanDefinitionScanner
