public class SimpleRemoteStatelessSessionProxyFactoryBean
extends SimpleRemoteSlsbInvokerInterceptor
implements org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.BeanClassLoaderAware

Convenient FactoryBean for remote SLSB proxies. Designed for EJB 2.x, but works for EJB 3 Session Beans as well.

See JndiObjectLocator for info on how to specify the JNDI location of the target EJB.

If you want control over interceptor chaining, use an AOP ProxyFactoryBean with SimpleRemoteSlsbInvokerInterceptor rather than rely on this class.

In a bean container, this class is normally best used as a singleton. However, if that bean container pre-instantiates singletons (as do the XML ApplicationContext variants) you may have a problem if the bean container is loaded before the EJB container loads the target EJB. That is because by default the JNDI lookup will be performed in the init method of this class and cached, but the EJB will not have been bound at the target location yet. The best solution is to set the lookupHomeOnStartup property to false, in which case the home will be fetched on first access to the EJB. (This flag is only true by default for backwards compatibility reasons).

This proxy factory is typically used with an RMI business interface, which serves as super-interface of the EJB component interface. Alternatively, this factory can also proxy a remote SLSB with a matching non-RMI business interface, i.e. an interface that mirrors the EJB business methods but does not declare RemoteExceptions. In the latter case, RemoteExceptions thrown by the EJB stub will automatically get converted to Spring's unchecked RemoteAccessException.

setBusinessInterface

public void setBusinessInterface(@Nullable
                                 Class<?> businessInterface)

Set the business interface of the EJB we're proxying. This will normally be a super-interface of the EJB remote component interface. Using a business methods interface is a best practice when implementing EJBs.

You can also specify a matching non-RMI business interface, i.e. an interface that mirrors the EJB business methods but does not declare RemoteExceptions. In this case, RemoteExceptions thrown by the EJB stub will automatically get converted to Spring's generic RemoteAccessException.

参数:

businessInterface - the business interface of the EJB

getBusinessInterface

@Nullable
public Class<?> getBusinessInterface()

Return the business interface of the EJB we're proxying.

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

指定者:

setBeanClassLoader 在接口中 org.springframework.beans.factory.BeanClassLoaderAware

afterPropertiesSet

public void afterPropertiesSet()
                        throws NamingException

从类复制的说明: AbstractSlsbInvokerInterceptor

Fetches EJB home on startup, if necessary.

指定者:

afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean

覆盖:

afterPropertiesSet 在类中 AbstractSlsbInvokerInterceptor

抛出:

NamingException

getObject 在接口中 org.springframework.beans.factory.FactoryBean<Object>

getObjectType

public Class<?> getObjectType()

指定者:

isSingleton

public boolean isSingleton()

指定者:
