如何从Java反射中获取String字段的值? [英] How to get value of String field from Java reflection?

问题描述

我有一个具有String字段的对象.我可以通过以下方式获取该字段:

I have an object that has a String field. I can obtain this field by calling:

Field field = someObj.getClass().getField("strField");

我设置了一个 Field#set(Object)方法，用于设置此实例字段的值，但是相应的getter似乎是 Field#get(Object)，这很奇怪，因为我希望它是 Field#get().

I sett a Field#set(Object) method, for setting the value of this instance's field, but the respective getter seems to be Field#get(Object), which is weird because I would have expected it to be Field#get().

如何获取实例的 strField 的值?

推荐答案

如果您使用的是 java.lang.reflect.Field ，则设置者"为 Field.set(Object，对象)，"getter"是 Field.get(Object).在两种情况下，第一个参数是您要在其上访问字段的实例.

if you are using java.lang.reflect.Field, the "setter" is Field.set(Object,Object) and the "getter" is Field.get(Object). in both cases, the first parameter is the instance on which you want to access the field.
