通过普通方式调用和反射方式调用以及关闭检测后，通过反射方式调用的性能对比

package Collections;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class text3 {
    //普通方式调用
    public static void text1() {
        person user = new person();
        long startTime = System.currentTimeMillis();
        for (int i = 0; i < 1000000000; i++) {
            user.getName();
        }
        long endTime = System.currentTimeMillis();
        System.out.println("普通方式执行10亿次;" + (endTime - startTime) + "ms");
    }
    //通过反射的方式调用
    public static void text2() throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
        person user = new person();
        Class c = user.getClass();
        Method getName = c.getDeclaredMethod("getName", null);
        long startTime = System.currentTimeMillis();
        for (int i = 0; i < 1000000000; i++) {
            getName.invoke("person", null);
        }
        long endTime = System.currentTimeMillis();
        System.out.println("反射方式执行10亿次;" + (endTime - startTime) + "ms");
    }
    //关闭检测后，通过反射的方式调用
    public static void text3() throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
        person user = new person();
        Class c = user.getClass();
        Method getName = c.getDeclaredMethod("getName", null);
        getName.setAccessible(true);

        System.out.println("关闭检测后，执行10亿次;" + (endTime - startTime) + "ms");
    }
    public static void main(String[] args) throws InvocationTargetException, NoSuchMethodException, IllegalAccessException {
        text1();
        text2();
        text3();
    }
}

普通方式执行10亿次;4ms
反射方式执行10亿次;6576ms
关闭检测后，执行10亿次;5577ms
