Spring8中lambda表达式的学习(Function接口、BiFunction接口、Consumer接口)

代码重构，为了确保功能的等效性，梳理代码时，发现如下代码：

 1 public  SingleRespTTO fundI(SingleReqTTO request) throws Exception {
 2     return handlerSingleReq((req, logInfo) -> {
 3        
 4         // 业务操作
 5         ....略....
 6     }, request);
 7 }
 8 
 9 public SingleRespTTO handlerSingleReq(BiConsumer<SingleReqTTO, SingleRespTTO> consumer,
10                                           SingleReqTTO request) throws Exception {
11     // 业务操作
12     consumer.accept(request, respTTO);
13         ....略....
14     return respTTO;
15 }
