Class MapMergeDirectiveBeanPostProcessor

java.lang.Object

de.hybris.platform.spring.config.MapMergeDirectiveBeanPostProcessor

Direct Known Subclasses:

MapMergeDirectiveBeanPostProcessor

public class MapMergeDirectiveBeanPostProcessor
extends java.lang.Object

This is BeanPostProcessor for adding items into existing maps.

It creates a cache of MapMergeDirective bean definitions found in the system during its initialization. Then each bean is checked if it should be modified by any of cached directives. If yes, we use BeanDefinitionValueResolver (custom implementation of spring class) to create a object out of beanDefiniton without creating a proper MapMergeDirective bean (this is impossible at this point as it would create circular dependency). The representation of MapMergeDirective is then applied to target bean.

Forcing this BeanPostProcessor to load all MapMergeDirective instances during its initialization (via dependency injection or by extracting them form ApplicationContext) will lead to change in order in which beans are intialized. Especially some beans will be instanciated before other BeanPostProcessors which may highly affect stability of the system, so its a bad idea.
