简单的一个性能收集类，

原理：在每个采集点上记录一条日志，完成后，如果总体时间超出要求，输出各个阶段的日志信息。

代码见下：

public class TimeWatch {
        //单阶段超时设置为high
        static long LIMITED = 20;
        private List<WatchItem> costList = new ArrayList<>();
        private long currentTime =0;
        private long allCost =0;
    
        public TimeWatch(){
            currentTime = System.currentTimeMillis();
        }
    
        public void stopAndWatchNext(String word){
            long endTime = System.currentTimeMillis();
            long cost = endTime - currentTime;
            allCost +=cost;
            WatchItem watchItem = new WatchItem(word,cost);
            costList.add(watchItem);
            currentTime = endTime;
        }
    
        public long getAllCost() {
            return allCost;
        }
    
        @Override
        public String toString() {
            return "TimeWatch{" +
                    "allCost=" + allCost +
                    ", costList=" + costList +
                    '}';
        }
    
        public static class WatchItem{
            //阶段
            public String stage;
            public long  cost;
    
            public WatchItem(String stage,long cost){
                this.stage = stage;
                this.cost = cost;
            }
    
            @Override
            public String toString() {
                if (cost > LIMITED){
                    return"Item{" +
                            "stage='" + stage + ",high'" +
                            ", cost=" + cost +
                            '}';
                }
                return "Item{" +
                        "stage='" + stage + '\'' +
                        ", cost=" + cost +
                        '}';
            }
        }
    
        public static void main(String[] args) {
            TimeWatch test = new TimeWatch();
            test.stopAndWatchNext("1");
            ThreadUtil.sleepS(1);//休息一秒
            test.stopAndWatchNext("2");
            System.out.println(test);
        }
    }

输出：

TimeWatch\{allCost=1002, costList=\[Item\{stage='1', cost=0\}, Item\{stage='2,high', cost=1002\}\]\}
