createStatement
public Object createStatement(Object proxy, Method method, Object[] args, Object statement, long time)
Description copied from class:AbstractCreateStatementInterceptorThis method will be invoked after a successful statement creation. This method can choose to return a wrapper around the statement or return the statement itself. If this method returns a wrapper then it should return a wrapper object that implements one of the following interfaces.Statement,PreparedStatementorCallableStatement- Specified by:
createStatementin classAbstractCreateStatementInterceptor- Parameters:
proxy- the actual proxy objectmethod- the method that was called. It will be one of the methods defined inAbstractCreateStatementInterceptor.STATEMENT_TYPESargs- the arguments to the methodstatement- the statement that the underlying connection createdtime- Elapsed time- Returns:
- a
Statementobject
