Class GaussBeanFactory

java.lang.Object

xyz.gaussframework.engine.basis.GaussBeanFactory

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class GaussBeanFactory
extends Object
implements org.springframework.context.ApplicationContextAware

GaussBeanFactory is a new dynamic way to acquire bean from Application Context(not only assigned from Spring) as a utility tool. Furthermore, it has been enhanced by a capability of "object copy". Please use wisely of getBean(java.lang.Class<T>) method coz it gives you the singleton by default if context is from Spring framework

Parameters:

clazz - class type the object

Returns:

an instance of the object

Throws:

GaussFactoryException

getBean

public static Object getBean(String name)

Get an instance of the object that client acquires through application context. Please use it wisely only if you are familiar with the underlying context container or use create(java.lang.Class<T>) instead if you are in unknown situation.

Parameters:

name - name of the object

Returns:

an instance of the object

create

public static <T> T create(Class<T> clazz)

create

public static <T> T create(Class<T> clazz,
                           Object... args)

use declared constructor to instantiate an object

Type Parameters:

T - the type of object

Parameters:

clazz - the class type of object

args - constructor parameters

Returns:

instance of object

create

public static <T> T create(Constructor<T> ctor,
                           Object... args)

use specific constructor to create an object

T - the type of object

Parameters:

ctor - the specific constructor of object

args - constructor parameters

Returns:

an instance of object

setApplicationContext

public void setApplicationContext(@NonNull
                                  org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Throws:

org.springframework.beans.BeansException - see ApplicationContextException
