如何启用Intellij热门代码交换 [英] How to enable Intellij hot code swap

问题描述

Intellij似乎没有在我的安装上进行基本的热代码交换。

Intellij does not seem to be doing basic hot code swap on my installation.

对于此代码：

public class MainTest {
    public void method1() {
        System.out.println("Breakpoint here");
    }

    public void method2() {
        System.out.println("Line that will get 24 modified");
    }

    public static void main(String[] args) {
        System.out.println("First print here");
        MainTest mainTest = new MainTest();
        mainTest.method1();
        mainTest.method2();
        System.out.println("Line that I do not modify");
    }
}

我在上放了一个断点mainTest.method1（）; 然后修改method2（）处的字符串，点击ctrl + s并继续一步一步。遗憾的是，运行时未更新，正在打印旧字符串。完全停止 - 编译 - 运行会打印新字符串。所以我的结论是热插拔不​​工作。

I put a breakpoint on mainTest.method1(); then modify the string at method2(), hit ctrl+s and continue to step by step. Unfortunately the runtime is not updated, old string is being printed. Full stop - compile - run does print the new string. So my conclusion is hot-swap not working.

我需要设置什么设置来启用热代码交换？

Is there any settings I need to set to enable hot code swap?

• Ubuntu，JDK 1.6


• Intellij 10.5 Ultimate（评估）

推荐答案

在等待断点的同时保存你的课程后，只需用 Build - >重新编译你的课程。使用标准键绑定编译'MainTest.java'或按 Ctrl + Shift + F9 。

After saving your class while waiting on your breakpoint just recompile your class with Build -> Compile 'MainTest.java' or press Ctrl+Shift+F9 with the standard key bindings.

IntelliJ IDEA将显示一个小对话框，询问您是否要重新加载该类。

IntelliJ IDEA will then show a small dialog in which it asks you if you want to reload that class.
