Get bean property getter or setter by reflection?
提问by C. Ross
Suppose I have a handle on an object of type , and I'm told by configuration that it has a bean property of type intwith the name age. How can I retrieve the getter for this document?
假设我有一个类型为 的对象的句柄，并且配置告诉我它有一个类型int为 name的 bean 属性age。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?
有没有比在 前面加上“get”并大写“a”age并通过反射寻找该名称的方法更好的方法？

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

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