IDEA多線程下多個線程切換斷點運行調試的技巧

多線程調試設置可以參考：http://www.cnblogs.com/leodaxin/p/7710630.html

 

1 斷點設置如圖：

 

 

2 測試代碼，然后進行debug

package com.daxin;
import java.util.HashMap;
/**

 public class HashMapInfiniteLoop {
 private static HashMap<Integer, Integer> map = new HashMap<Integer, Integer>(2, 0.75f);
 
public static void main(String[] args) throws InterruptedException {
 map.put(5, 55);
 
 </span><span style="color: #0000ff;">new</span> Thread("Thread1-Name"<span style="color: #000000;">) {
     </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> run() {
         System.out.println(</span>"Thread1-Name Start"<span style="color: #000000;">);
         </span><span style="color: #0000ff;">try</span><span style="color: #000000;"> {
             Thread.sleep(</span>5000<span style="color: #000000;">);
         } </span><span style="color: #0000ff;">catch</span><span style="color: #000000;"> (InterruptedException e) {
             e.printStackTrace();
         }
         map.put(</span>7, 77);<span style="color: #008000;">//</span><span style="color: #008000;">斷點位置 1</span>
 
 
           
 System.out.println(map);
 }
    }.start();
    </span><span style="color: #0000ff;">new</span> Thread("Thread2-Name"<span style="color: #000000;">) {

        </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> run() {
            </span><span style="color: #0000ff;">try</span><span style="color: #000000;"> {
                System.out.println(</span>"Thread2-Name Start"<span style="color: #000000;">);
                Thread.sleep(</span>5000<span style="color: #000000;">);
            } </span><span style="color: #0000ff;">catch</span><span style="color: #000000;"> (InterruptedException e) {
                e.printStackTrace();
            }
            map.put(</span>3, 33);<span style="color: #008000;">//</span><span style="color: #008000;"> 斷點位置2</span>

 System.out.println(map);
 }
    }.start();


    </span><span style="color: #008000;">//</span><span style="color: #008000;"> 斷點位置 3</span>
    System.out.println("Thread-Main-Name Start"<span style="color: #000000;">);
    System.out.println(</span>"Thread-Main-Name Start"<span style="color: #000000;">);
    System.out.println(</span>"Thread-Main-Name Start"<span style="color: #000000;">);


    Thread.sleep(</span>500000<span style="color: #000000;">);

}

}

 

3：啟動debug，我們可以在Threads Tab選項雙擊需要進行單步調試的線程

然后選擇Frames Tab選項中調試的線程進行快捷鍵調試即可。
