通过函数式参数对行为解耦

    @RequestMapping(value = "/listByVin", method = RequestMethod.GET)
    public String listByType(@RequestParam(value = "vin") String vin) {
        //正常写法
        try {
            return testService2.handler1(vin);
        }catch (Exception e){
            e.printStackTrace();
        }

        //函数式写法
        return ServerExeutor.executeAndReturn(() -> testService2.handler1(vin));
    }


    @RequestMapping(value = "/listByVin2", method = RequestMethod.GET)
    public String listByVin2(@RequestParam(value = "vin") String vin,@RequestParam(value = "status") Short status) {
        //正常写法
        try {
            testService2.handler2(vin,status);
        }catch (Exception e){
            e.printStackTrace();
        }
        //函数式写法
        ServerExeutor.execute(() -> testService2.handler2(vin,status));
        return "执行不带参函数完成";
    }
