SimpleRemoteSlsbInvokerInterceptor

public abstract class AbstractRemoteSlsbInvokerInterceptor
extends AbstractSlsbInvokerInterceptor

Base class for interceptors proxying remote Stateless Session Beans. Designed for EJB 2.x, but works for EJB 3 Session Beans as well.

Such an interceptor must be the last interceptor in the advice chain. In this case, there is no target object.

方法详细资料

setRefreshHomeOnConnectFailure

public void setRefreshHomeOnConnectFailure(boolean refreshHomeOnConnectFailure)

Set whether to refresh the EJB home on connect failure. Default is "false".

Can be turned on to allow for hot restart of the EJB server. If a cached EJB home throws an RMI exception that indicates a remote connect failure, a fresh home will be fetched and the invocation will be retried.

ConnectException, ConnectIOException, NoSuchObjectException

isHomeRefreshable

protected boolean isHomeRefreshable()

从类复制的说明: AbstractSlsbInvokerInterceptor

Return whether the cached EJB home object is potentially subject to on-demand refreshing. Default is "false".

覆盖:

isHomeRefreshable 在类中 AbstractSlsbInvokerInterceptor

getCreateMethod

protected Method getCreateMethod(Object home)
                          throws EjbAccessException

Check for EJB3-style home object that serves as EJB component directly.

覆盖:

getCreateMethod 在类中 AbstractSlsbInvokerInterceptor

参数:

home - the EJB home object

返回:

the create method

抛出:

EjbAccessException - if the method couldn't be retrieved

invokeInContext

@Nullable
public Object invokeInContext(org.aopalliance.intercept.MethodInvocation invocation)
                                  throws Throwable

Fetches an EJB home object and delegates to doInvoke.

If configured to refresh on connect failure, it will call refreshAndRetry(org.aopalliance.intercept.MethodInvocation) on corresponding RMI exceptions.

指定者:

invokeInContext 在类中 AbstractSlsbInvokerInterceptor

参数:

invocation - the AOP method invocation

返回:

the invocation result, if any

抛出:

Throwable - in case of invocation failure

另请参阅:

AbstractSlsbInvokerInterceptor.getHome(), doInvoke(org.aopalliance.intercept.MethodInvocation), refreshAndRetry(org.aopalliance.intercept.MethodInvocation)

isConnectFailure

protected boolean isConnectFailure(RemoteException ex)

Determine whether the given RMI exception indicates a connect failure.

The default implementation delegates to RmiClientInterceptorUtils.

参数:

ex - the RMI exception to check

返回:

whether the exception should be treated as connect failure

另请参阅:

RmiClientInterceptorUtils.isConnectFailure(java.rmi.RemoteException)

refreshAndRetry

@Nullable
protected Object refreshAndRetry(org.aopalliance.intercept.MethodInvocation invocation)
                                     throws Throwable

Refresh the EJB home object and retry the given invocation. Called by invoke on connect failure.

参数:

invocation - the AOP method invocation

返回:

the invocation result, if any

抛出:

Throwable - in case of invocation failure

另请参阅:

AbstractSlsbInvokerInterceptor.invoke(org.aopalliance.intercept.MethodInvocation)

doInvoke

@Nullable
protected abstract Object doInvoke(org.aopalliance.intercept.MethodInvocation invocation)
                                       throws Throwable

Perform the given invocation on the current EJB home. Template method to be implemented by subclasses.

参数:

invocation - the AOP method invocation

返回:

the invocation result, if any

抛出:

Throwable - in case of invocation failure

newSessionBeanInstance

protected Object newSessionBeanInstance()
                                 throws NamingException,
                                        InvocationTargetException

Return a new instance of the stateless session bean. To be invoked by concrete remote SLSB invoker subclasses.

Can be overridden to change the algorithm.

抛出:

NamingException - if thrown by JNDI

InvocationTargetException - if thrown by the create method

AbstractSlsbInvokerInterceptor.create()

removeSessionBeanInstance

protected void removeSessionBeanInstance(@Nullable
                                         EJBObject ejb)

Remove the given EJB instance. To be invoked by concrete remote SLSB invoker subclasses.

参数:

ejb - the EJB instance to remove
