优秀博文(案例)
No context holder available for step scope
StepContext stepContext = StepSynchronizationManager.register(stepExecution);
StepScope#getContext()
AbstractBeanFactory#doGetBean
mbd.isSingleton()
mbd.isPrototype()
mbd.getScope()
如何获取->StepScope#get(String, ObjectFactory)
如何写入->BatchScopeSupport#postProcessBeanFactory
BeanFactoryPostProcessor
BeanPostProcessor
如何注册->ScopeConfiguration#stepScope()
AbstractBatchConfiguration
@EnableBatchProcessing#BatchConfigurationSelector
AbstractBeanFactory是bean工厂最核心的实现所有bean相关都在此
