Timer stopwatch in spring

1 Overview

You need to record the execution time of each task, or record a period of code execution, simply by printing the difference between the current time and the execution time, and if performing a large number of tests is cumbersome and not intuitive. If you want to control the execution time further, you need to modify it in many parts of the program. Spring-framework provides a stopwatch class that can do similar task execution time control.

stopwatch SW = new stopwatch ();
Sw.start ();
Business Operation
Sw.stop ();
Logger.info ("Time consuming:" + sw.gettotaltimemillis ());

2 match interceptors use spring stopwatch in the filter to count the execution times of each request. Add the following code to the Dofilter of filter:

Stopwatch stopwatch = new Stopwatch (Url+system.currenttimemillis ());  
Stopwatch.start ();  
Dofilter (ARG0,ARG1);  
Opwatch.stop ();  
Loginfo (Stopwatch.gettotaltimemillis () + "---" +request.getrequesturi () + "Execution Time");

As you can see from the source code constructs, stopwatch constructs the object according to the ID, ensuring that the unique construction ID distinguishes between different requests.

Public stopwatch () { 
    keeptasklist = true;  
    TaskList = new LinkedList ();  
    id = "";  
}  
  
Public stopwatch (String ID) {  
    keeptasklist = true;  
    TaskList = new LinkedList ();  
    This.id = ID;  
}
