Class ServletContextAwareProcessor

java.lang.Object
org.springframework.web.context.support.ServletContextAwareProcessor
All Implemented Interfaces:
BeanPostProcessor

public class ServletContextAwareProcessor extends Object implements BeanPostProcessor
BeanPostProcessor implementation that passes the ServletContext to beans that implement the ServletContextAware interface.

Web application contexts will automatically register this with their underlying bean factory. Applications do not use this directly.

  • Constructor Details

    • ServletContextAwareProcessor

      protected ServletContextAwareProcessor()
      Create a new ServletContextAwareProcessor without an initial context or config. When this constructor is used the getServletContext() and/or getServletConfig() methods should be overridden.
    • ServletContextAwareProcessor

      public ServletContextAwareProcessor(ServletContext servletContext)
      Create a new ServletContextAwareProcessor for the given context.
    • ServletContextAwareProcessor

      public ServletContextAwareProcessor(ServletConfig servletConfig)
      Create a new ServletContextAwareProcessor for the given config.
    • ServletContextAwareProcessor

      public ServletContextAwareProcessor(@Nullable ServletContext servletContext, @Nullable ServletConfig servletConfig)
      Create a new ServletContextAwareProcessor for the given context and config.
  • Method Details

    • getServletContext

      @Nullable protected ServletContext getServletContext()
      Returns the ServletContext to be injected or null. This method can be overridden by subclasses when a context is obtained after the post-processor has been registered.
    • getServletConfig

      @Nullable protected ServletConfig getServletConfig()
      Returns the ServletConfig to be injected or null. This method can be overridden by subclasses when a context is obtained after the post-processor has been registered.
    • postProcessBeforeInitialization

      public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException
      Description copied from interface: BeanPostProcessor
      Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

      The default implementation returns the given bean as-is.

      Specified by:
      postProcessBeforeInitialization in interface BeanPostProcessor
      Parameters:
      bean - the new bean instance
      beanName - the name of the bean
      Returns:
      the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
      Throws:
      BeansException - in case of errors

    • postProcessAfterInitialization

      public Object postProcessAfterInitialization(Object bean, String beanName)
      Description copied from interface: BeanPostProcessor
      Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

      In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding bean instanceof FactoryBean checks.

      This callback will also be invoked after a short-circuiting triggered by a InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) method, in contrast to all other BeanPostProcessor callbacks.

      The default implementation returns the given bean as-is.

      Specified by:
      postProcessAfterInitialization in interface BeanPostProcessor
      Parameters:
      bean - the new bean instance
      beanName - the name of the bean
      Returns:
      the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
