类加载器一问的补充说明Java->JVM->6.类加载器 #871

不想用双亲委派模型肯定不是覆盖findClass方法呀,覆盖这个方法就等于默认使用双亲委派模型。

如果我们不想用双亲委派模型怎么办?
不想使用双亲委派模型,我们可以自定义自己的类加载器,需要继承 java.lang.ClassLoader,但是如果是要自定类加载器,也是需要继承ClassLoader,但是覆盖的是findClass方法,这点需要做下补充说明,这点看源码就可以确认,可以参考博客:https://blog.csdn.net/SEU_Calvin/article/details/52315125,因为最近面试经常被问到,之前被误导了,面试官反复确认,我还是说是重写`loadClass`方法,因而这点感觉需要做下补充说明。

没问题的,就是可能之前我没表述清楚,我想表达的是:之前楼主没有对这个情况做区分说明,感觉容易引起误导(我就是),双亲委派模型->重写loadClass()方法,自定义类加载器->重写findClass()方法应该需要被强调一下。 |
