Serializable, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.FactoryBean, org.springframework.beans.factory.InitializingBean

public class TargetClassLoaderTransactionProxyFactoryBean
extends org.springframework.transaction.interceptor.TransactionProxyFactoryBean

Proxy factory bean that extends TransactionProxyFactoryBean to use the class loader that the class of the target object was loaded from. This can be used as a drop-in replacement for TransactionProxyFactoryBean in situations where the proxy interface is not visible in the current context class loader. In particular, this is useful for creating transaction-wrapped beans in plugin descriptors.

Since:

2.9

Constructor Detail

TargetClassLoaderTransactionProxyFactoryBean

public TargetClassLoaderTransactionProxyFactoryBean()

Method Detail

setTarget

public void setTarget(Object target)

Set 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.

Overrides:

setTarget in class org.springframework.aop.framework.AbstractSingletonProxyFactoryBean

Parameters:

target - the object that will be wrapped with a transactional argument. Must not be null.

Throws:

IllegalArgumentException - if the target parameter is null

getProxy

protected Object getProxy(org.springframework.aop.framework.AopProxy proxy)

Returns the proxy object to expose.

This implementation uses the class loader of the target object, to allow plugins to use transaction-wrapped beans.

Overrides:

getProxy in class org.springframework.aop.framework.AbstractSingletonProxyFactoryBean

Parameters:

proxy - the prepared AopProxy instance to get the proxy from

Returns:

the proxy object to expose
