An automated refactoring approach for asynchronous mechanism

As synchronous blocking wastes system resources and affects program performance in concurrent processing,an automatic refactoring approach based on the asynchronous mechanism of CompletableFuture was proposed.Firstly,several static analyses by Wala static program analysis tool,such as visitor patter...
