JRebel不会重新加载更改
怎么了?在您的示例中,执行永远不会超出while循环,因此它永远不会超出方法。在执行过程中,一个方法不能被替换,所以要重新加载执行应该首先退出该方法。 这样做:
public class App {
public static void main(String[] args) throws Exception {
Bean bean = new Bean();
for (; ;) {
bean.foo();
Thread.sleep(1000);
}
}
}
public class Bean {
public void foo(){
System.out.println("Hello jrebel");
}
}
现在您可以在Bean类中更改任何内容,但不能在while循环中更改—可以重新加载该类,但该方法永远不会退出,因此永远不会有机会执行新指令
顺便说一句,别忘了编译修改过的类。感谢您的解释和一个很棒的插件!变魔术。也在Web应用程序下测试。
