A org.hibernate.context.spi.CurrentSessionContext impl which scopes the notion of current session by the current thread of execution. Unlike the JTA counterpart, threads do not give us a nice hook to perform any type of cleanup making it questionable for this impl to actually generate Session instances. In the interest of usability, it was decided to have this default impl actually generate a session upon first request and then clean it up after the org.hibernate.Transaction associated with that session is committed/rolled-back. In order for ensuring that happens, the sessions generated here are unusable until after Session#beginTransaction() has been called. If close() is called on a session managed by this class, it will be automatically unbound. Additionally, the static bind and unbind methods are provided to allow application code to explicitly control opening and closing of these sessions. This, with some from of interception, is the preferred approach. It also allows easy framework integration and one possible approach for implementing long-sessions. The buildOrObtainSession, isAutoCloseEnabled, isAutoFlushEnabled, getConnectionReleaseMode, and buildCleanupSynch methods are all provided to allow easy subclassing (for long-running session scenarios, for example).

public Object invoke(Object proxy, Method method, Object[] args) throws Throwable

Implements java.lang.reflect.InvocationHandler.invoke.

Doc from java.lang.reflect.InvocationHandler.invoke.

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Parameters

proxy:Object: the proxy instance that the method was invoked on
method:Method: the Method instance corresponding to the interface method invoked on the proxy instance. The declaring class of the Method object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through.
args:Object[]: an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.

Returns:Object

the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is null and the interface method's return type is primitive, then a NullPointerException will be thrown by the method invocation on the proxy instance.

If a checked exception is thrown by this method that is not assignable to any of the exception types declared in the throws clause of the interface method, then an UndeclaredThrowableException containing the exception that was thrown by this method will be thrown by the method invocation on the proxy instance.
