Bean factory, Application Context - bhudevi0924/Spring-boot GitHub Wiki
BeanFactory interface is the simplest container providing an advanced configuration mechanism to instantiate, configure, and manage the life cycle of beans.
<style> </style>| Method | Description |
|---|---|
| containsBean(String name) | Does this bean factory contain a bean definition or externally registered singleton instance with the given name? |
| getAliases(String name) | Return the aliases for the given bean name, if any. |
| getBean(Class requiredType) | Return the bean instance that uniquely matches the given object type, if any. |
| getBean(Class requiredType, Object… args) | Return an instance, which may be shared or independent, of the specified bean. |
| getBean(String name) | Return an instance, which may be shared or independent, of the specified bean. |
| getBean(String name, Class requiredType) | Return an instance, which may be shared or independent, of the specified bean. |
| getBean(String name, Object… args) | Return an instance, which may be shared or independent, of the specified bean. |
| getBeanProvider(Class requiredType) | Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options. |
| getBeanProvider(ResolvableType requiredType) | Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options. |
| getType(String name) | Determine the type of the bean with the given name. |
| getType(String name, boolean allowFactoryBeanInit) | Determine the type of the bean with the given name. |
| isPrototype(String name) | Is this bean a prototype? That is, will getBean(java.lang.String) always return independent instances? |
| isSingleton(String name) | Is this bean a shared singleton? That is, will getBean(java.lang.String) always return the same instance? |
| isTypeMatch(String name, Class<?> typeToMatch) | Check whether the bean with the given name matches the specified type. |
| isTypeMatch(String name, ResolvableType typeToMatch) | Check whether the bean with the given name matches the specified type. |
-> Application Context:
- The application context is the central interface within a Spring application for providing configuration information to the Spring IoC container and for managing the lifecycle of Spring beans. It essentially represents the Spring IoC container and is responsible for instantiating, configuring, and assembling the beans. The application context loads bean definitions, wires beans together, and manages the complete lifecycle of the beans.
