Functions ¶
func NewSkipInitializationPostProcessor ¶
func NewSkipInitializationPostProcessor() container.ComponentPostProcessor
NewSkipInitializationPostProcessor builds a SkipInitializationPostProcessor.
func SkipComponentInitialization ¶
func SkipComponentInitialization() app.SettingOption
SkipComponentInitialization returns a SettingOption that performs dependency injection only: every component's Init()/AfterPropertiesSet() is skipped and all ApplicationRunner.Run() invocations are skipped as well.
It is intended for local development when real dependencies (databases, cluster services, etc.) are unreachable but the wiring/injection capability is still needed. Note that since initialization is short-circuited, the after-initialization processor chain (e.g. AOP proxying done in PostProcessAfterInitialization) is also skipped for every component.
Usage:
ioc.Run(ext.SkipComponentInitialization(), app.SetComponents(...))
Types ¶
type SkipInitializationPostProcessor ¶
type SkipInitializationPostProcessor struct {
processors.DefaultComponentPostProcessor
}
SkipInitializationPostProcessor skips the initialization phase of every component. By returning nil from PostProcessBeforeInitialization it short-circuits Factory's InitializeComponentWithContext before invokeInitMethods runs, so neither Init()/Init(ctx) nor AfterPropertiesSet() is called.
Dependency injection (wire/value/prop/prefix/func) is unaffected: it completes during the populate phase, which happens before initialization.
func (*SkipInitializationPostProcessor) Order ¶
func (p *SkipInitializationPostProcessor) Order() int
Order places this processor at the end of the ordered ComponentPostProcessor chain.
func (*SkipInitializationPostProcessor) PostProcessBeforeInitialization ¶
func (p *SkipInitializationPostProcessor) PostProcessBeforeInitialization(component any, componentName string) (any, error)
PostProcessBeforeInitialization returns nil to skip the component's initialization methods. The factory keeps and exposes the already-populated instance unchanged.
