public class SimpleRemoteSlsbInvokerInterceptor
extends AbstractRemoteSlsbInvokerInterceptor
implements DisposableBean
```
Basic invoker for a remote Stateless Session Bean. Designed for EJB 2.x, but works for EJB 3 Session Beans as well.
"Creates" a new EJB instance for each invocation, or caches the session bean instance for all invocations (see setCacheSessionBean(boolean)). See JndiObjectLocator for info on how to specify the JNDI location of the target EJB.
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 invoker is typically used with an RMI business interface, which serves as super-interface of the EJB component interface. Alternatively, this invoker 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.

- 方法详细资料
  - setCacheSessionBean
```
public void setCacheSessionBean(boolean cacheSessionBean)
```
    Set whether to cache the actual session bean object.
    Off by default for standard EJB compliance. Turn this flag on to optimize session bean access for servers that are known to allow for caching the actual session bean object.

    AbstractSlsbInvokerInterceptor.setCacheHome(boolean)
  - doInvoke
```
protected Object doInvoke(MethodInvocation invocation)
                   throws Throwable
```
    This implementation "creates" a new EJB instance for each invocation. Can be overridden for custom invocation strategies.
    Alternatively, override getSessionBeanInstance() and releaseSessionBeanInstance(javax.ejb.EJBObject) to change EJB instance creation, for example to hold a single shared EJB component instance.
    指定者:
    doInvoke 在类中 AbstractRemoteSlsbInvokerInterceptor
    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(), AbstractRemoteSlsbInvokerInterceptor.newSessionBeanInstance()
  - getSessionBeanInstance
```
protected Object getSessionBeanInstance()
                                 throws NamingException,
                                        InvocationTargetException
```
    Return an EJB component instance to delegate the call to.
    The default implementation delegates to AbstractRemoteSlsbInvokerInterceptor.newSessionBeanInstance().
    返回:
    the EJB component instance
    抛出:
    NamingException - if thrown by JNDI
    InvocationTargetException - if thrown by the create method
    另请参阅:
    AbstractRemoteSlsbInvokerInterceptor.newSessionBeanInstance()
  - releaseSessionBeanInstance
```
protected void releaseSessionBeanInstance(EJBObject ejb)
```
    Release the given EJB instance.
    The default implementation delegates to AbstractRemoteSlsbInvokerInterceptor.removeSessionBeanInstance(javax.ejb.EJBObject).
    参数:
    ejb - the EJB component instance to release
    另请参阅:
    AbstractRemoteSlsbInvokerInterceptor.removeSessionBeanInstance(javax.ejb.EJBObject)
  - refreshHome
```
protected void refreshHome()
                    throws NamingException
```
    Reset the cached session bean instance, if necessary.
    覆盖:
    refreshHome 在类中 AbstractSlsbInvokerInterceptor
    抛出:
    NamingException - if thrown by the JNDI lookup
    另请参阅:
    JndiObjectLocator.lookup(), AbstractSlsbInvokerInterceptor.getCreateMethod(java.lang.Object)
  - destroy
```
public void destroy()
```
    Remove the cached session bean instance, if necessary.
    指定者:
    destroy 在接口中 DisposableBean
