private Class<?> extractDeclaringClass(ResolvableType beanType, Executable executable)
extractTargetClassFromFactoryBeanback to summary
private Class<?> extractTargetClassFromFactoryBean(Class<?> factoryBeanType, ResolvableType beanType)

Extract the target class of a public FactoryBean based on its constructor. If the implementation does not resolve the target class because it itself uses a generic, attempt to extract it from the bean type.

Parameters
factoryBeanType:Class<?>

the factory bean type

beanType:ResolvableType

the bean type

Returns:Class<?>

the target class to use

Implements org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateInstanceSupplierCode.

Doc from org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateInstanceSupplierCode.

Generate the instance supplier code.

Parameters
generationContext:GenerationContext

the generation context

beanRegistrationCode:BeanRegistrationCode

the bean registration code

allowDirectSupplierShortcut:boolean

if direct suppliers may be used rather than always needing an InstanceSupplier

Returns:CodeBlock

the generated code

public CodeBlock generateNewBeanDefinitionCode(GenerationContext generationContext, ResolvableType beanType, BeanRegistrationCode beanRegistrationCode)

Implements org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateNewBeanDefinitionCode.

Doc from org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateNewBeanDefinitionCode.

Generate the code that defines the new bean definition instance.

This should declare a variable named beanDefinition so that further fragments can refer to the variable to further tune the bean definition.

Parameters
generationContext:GenerationContext

the generation context

beanType:ResolvableType

the bean type

beanRegistrationCode:BeanRegistrationCode

the bean registration code

Returns:CodeBlock

the generated code

Implements org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateReturnCode.

Doc from org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateReturnCode.

Generate the return statement.

Parameters
generationContext:GenerationContext

the generation context

beanRegistrationCode:BeanRegistrationCode

the bean registration code

Returns:CodeBlock

the generated code

Implements org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateSetBeanDefinitionPropertiesCode.

Doc from org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateSetBeanDefinitionPropertiesCode.

Generate the code that sets the properties of the bean definition.

Parameters
generationContext:GenerationContext

the generation context

beanRegistrationCode:BeanRegistrationCode

the bean registration code

attributeFilter:Predicate<String>

any attribute filtering that should be applied

Returns:CodeBlock

the generated code

public CodeBlock generateSetBeanInstanceSupplierCode(GenerationContext generationContext, BeanRegistrationCode beanRegistrationCode, CodeBlock instanceSupplierCode, List<MethodReference> postProcessors)

Implements org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateSetBeanInstanceSupplierCode.

Doc from org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.generateSetBeanInstanceSupplierCode.

Generate the code that sets the instance supplier on the bean definition.

The postProcessors represent methods to be exposed once the instance has been created to further configure it. Each method should accept two parameters, the RegisteredBean and the bean instance, and should return the modified bean instance.

Parameters
generationContext:GenerationContext

the generation context

beanRegistrationCode:BeanRegistrationCode

the bean registration code

instanceSupplierCode:CodeBlock

the instance supplier code supplier code

postProcessors:List<MethodReference>

any instance post processors that should be applied

Returns:CodeBlock

the generated code

public ClassName getTarget(RegisteredBean registeredBean)

Implements org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.getTarget.

Doc from org.springframework.beans.factory.aot.BeanRegistrationCodeFragments.getTarget.

Return the target for the registration. Used to determine where to write the code. This should take into account visibility issue, such as package access of an element of the bean to register.

Parameters
registeredBean:RegisteredBean

the registered bean

Returns:ClassName

the target ClassName
