Class AbstractSingletonProxyFactoryBean

java.lang.Object

org.springframework.aop.framework.ProxyConfig

org.springframework.aop.framework.AbstractSingletonProxyFactoryBean

All Implemented Interfaces:

Serializable, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.InitializingBean

public abstract class AbstractSingletonProxyFactoryBean
extends ProxyConfig
implements org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.InitializingBean

Convenient superclass for FactoryBean types that produce singleton-scoped proxy objects.

Manages pre- and post-interceptors (references, rather than interceptor names, as in ProxyFactoryBean) and provides consistent interface management.

2.0

Constructor Detail

AbstractSingletonProxyFactoryBean

public AbstractSingletonProxyFactoryBean()

Method Detail

setTarget

public void setTarget(Object target)

Set the target object, that is, the bean to be wrapped with a transactional proxy.

The target may be any object, in which case a SingletonTargetSource will be created. If it is a TargetSource, no wrapper TargetSource is created: This enables the use of a pooling or prototype TargetSource etc.

See Also:

TargetSource, SingletonTargetSource, LazyInitTargetSource, PrototypeTargetSource, CommonsPoolTargetSource

setProxyInterfaces

public void setProxyInterfaces(Class<?>[] proxyInterfaces)

Specify the set of interfaces being proxied.

If not specified (the default), the AOP infrastructure works out which interfaces need proxying by analyzing the target, proxying all the interfaces that the target object implements.

setPreInterceptors

public void setPreInterceptors(Object[] preInterceptors)

Set additional interceptors (or advisors) to be applied before the implicit transaction interceptor, e.g. a PerformanceMonitorInterceptor.

You may specify any AOP Alliance MethodInterceptors or other Spring AOP Advices, as well as Spring AOP Advisors.

See Also:

PerformanceMonitorInterceptor

setPostInterceptors

public void setPostInterceptors(Object[] postInterceptors)

Set additional interceptors (or advisors) to be applied after the implicit transaction interceptor.

You may specify any AOP Alliance MethodInterceptors or other Spring AOP Advices, as well as Spring AOP Advisors.

setAdvisorAdapterRegistry

public void setAdvisorAdapterRegistry(AdvisorAdapterRegistry advisorAdapterRegistry)

Specify the AdvisorAdapterRegistry to use. Default is the global AdvisorAdapterRegistry.

See Also:

GlobalAdvisorAdapterRegistry

setProxyClassLoader

public void setProxyClassLoader(ClassLoader classLoader)

Set the ClassLoader to generate the proxy class in.

Default is the bean ClassLoader, i.e. the ClassLoader used by the containing BeanFactory for loading all bean classes. This can be overridden here for specific proxies.

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

Specified by:

setBeanClassLoader in interface org.springframework.beans.factory.BeanClassLoaderAware

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

createTargetSource

protected TargetSource createTargetSource(Object target)

Determine a TargetSource for the given target (or TargetSource).

Parameters:

target - target. If this is an implementation of TargetSource it is used as our TargetSource; otherwise it is wrapped in a SingletonTargetSource.

Returns:

a TargetSource for this object

getObject

public Object getObject()

Specified by:

getObject in interface org.springframework.beans.factory.FactoryBean<Object>

getObjectType

public Class<?> getObjectType()

Specified by:

getObjectType in interface org.springframework.beans.factory.FactoryBean<Object>

isSingleton

public final boolean isSingleton()

Specified by:

isSingleton in interface org.springframework.beans.factory.FactoryBean<Object>

createMainInterceptor

protected abstract Object createMainInterceptor()

Create the "main" interceptor for this proxy factory bean. Typically an Advisor, but can also be any type of Advice.

Pre-interceptors will be applied before, post-interceptors will be applied after this interceptor.
