IDEA告警详解：Optional.isPresent can be replaced with functional-style expression

Posted 2022-07-30 JavaEdge.

类似 if(Optional.isPresent()) 的条件语句，可以被重写成函数式风格。

if (!response.isPresent()) 
    return Result.success(null);

 else 
    return Result.success(response.get());

response.map(Result::success)
	.orElseGet(() -> Result.success(null));
