Method Details

getLazyResolutionProxyIfNecessary

@Nullable
public Object getLazyResolutionProxyIfNecessary(DependencyDescriptor descriptor,
 @Nullable
 String beanName)

Description copied from interface: AutowireCandidateResolver

Build a proxy for lazy resolution of the actual dependency target, if demanded by the injection point.

The default implementation simply returns null.

Specified by:

getLazyResolutionProxyIfNecessary in interface AutowireCandidateResolver

Overrides:

getLazyResolutionProxyIfNecessary in class SimpleAutowireCandidateResolver

Parameters:

descriptor - the descriptor for the target method parameter or field

beanName - the name of the bean that contains the injection point

Returns:

the lazy resolution proxy for the actual dependency target, or null if straight resolution is to be performed

getLazyResolutionProxyClass

@Nullable
public Class<?> getLazyResolutionProxyClass(DependencyDescriptor descriptor,
 @Nullable
 String beanName)

Description copied from interface: AutowireCandidateResolver

Determine the proxy class for lazy resolution of the dependency target, if demanded by the injection point.

The default implementation simply returns null.

Specified by:

getLazyResolutionProxyClass in interface AutowireCandidateResolver

Overrides:

getLazyResolutionProxyClass in class SimpleAutowireCandidateResolver

Parameters:

descriptor - the descriptor for the target method parameter or field

beanName - the name of the bean that contains the injection point

Returns:

the lazy resolution proxy class for the dependency target, if any

isLazy

protected boolean isLazy(DependencyDescriptor descriptor)

buildLazyResolutionProxy

protected Object buildLazyResolutionProxy(DependencyDescriptor descriptor,
 @Nullable
 String beanName)
