Java - Controller 压测 VS Main 压测

可能第一次你看到这个标题不懂在讲什么？其实很简单，就是介绍在 Spring 里 Controller 方法里进行调用A方法和在 Main 方法里进行调用同一个A方法的时间消耗对比！

Main 压测

/**
 * @author Lux Sun
 * @date 2020/11/4
 */
@Slf4j
public class Test {

    public static void main(String[] args) {
        StopWatch sw = new StopWatch();
        sw.start();
        // 业务代码A
        sw.stop();
        log.info("Main-Time: {}", sw.getTotalTimeMillis());
    }                
}      

Controller 压测

/**
 * @author Lux Sun
 * @date 2020/6/18
 */
@Slf4j
@RestController
public class ExecController {

    @GetMapping("/test")
    public void test() {
        StopWatch sw = new StopWatch();
        sw.start();
        // 业务代码A
        sw.stop();
        log.info("Controller-Time: {}", sw.getTotalTimeMillis());
    }
}
