项目中用到了java的反射,可以大大减少代码量.但是反射的性能却不容乐观,做了个简单的测试,如下. public void noreflect() { Person p = new Person(); for(int i=0; i<10000000; ++i){ Person.setName(p, "name"); Person.setAge(p, "22"); } } @Test public void reflect(){ Person p = new P
看了很多关于java 反射的文章,自己把所看到的总结一下.对自己,对他人或多或少有帮助吧. Java Reflection是什么? 首先来看看官方文档Oracle里面对Reflection的描述: Reflection is commonly used by programs which require the ability to examine or modify the runtime behavior of applications running in the Java virtual
Java反射 1.示例 1.用户类 package com.lf.entity; import com.lf.annotation.SetProperty; import com.lf.annotation.SetTable; public class UserEntity { private String userName; private int userAge; private final int money = 10000; public String getUserName() { r
