通过反射获取bean属性getter或setter？

[英]Get bean property getter or setter by reflection?

 原文  2011-07-27 13:56:26  1   1    java/ reflection/ javabeans

问题描述

Suppose I have a handle on an object of type , and I'm told by configuration that it has a bean property of type int with the name age . 假设我有一个类型对象的句柄，我通过配置告诉它它有一个int类型的bean属性，名称为age 。 How can I retrieve the getter for this document? 如何检索此文档的getter？

Is there a better way than prepending "get" and capitalizing the "a" in age , and looking for a method of that name via reflection? 有没有一种更好的方法比在“ age ”中加上“获得”和大写“a”，并通过反思寻找一个名称的方法？

Take a look at java.beans.Introspector . 看看java.beans.Introspector 。 This class allows you to get the list of properties on a class. 此类允许您获取类的属性列表。

If you know property name you can call 如果您知道您可以致电的房产名称 

Method getter = new PropertyDescriptor(propertyName, beanClass).getReadMethod();
