         @PECounter(namespace="test", name="demo", value=1, labels={"test":"ok"}, help="123")
         value是 调用改方法会增加或者减少的值

         @PEHistogram(namespace="test", name="demo", labels={"test":"ok"}, help="123")
         该注解的作用是记录调用该方法的整个执行时间再进行Histogram

         @PEGauge(namespace="test", name="demo", value=1, labels={"test":"ok"}, help="123")
         @PEGaugeAfter(namespace="test", name="demo", returnKey="data,aa", labels={"test":"ok"}, help="123")
         两者区别在于一个依赖默认值，一个依赖返回值
         After注解的方法返回值必须是个数组，逗号代表着层级
