Remote Debugging (2)

use Eclipse| a Java application

创建一个简单的maven项目

Main.java

package cn.zno;

public class Main {

    public static void main(String[] args) {
        for (String arg : args) {
            System.out.println(arg);
        }
    }

}

Main.java

Building jar

右键项目

[INFO] Building jar: F:\e\workspacetest\za\target\za-1.0.jar

以调试模式远程启动

F:\>java -cp F:\e\workspacetest\za\target\za-1.0.jar -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend
=y cn.zno.Main a b c
Listening for transport dt_socket at address: 8000
_

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=y

现在处于挂起状态，等待debugger 启动

启动debugger

配置需要调试的项目，Host 和 Port

其中Host 是远程电脑的ip ,Port 为远程电脑debug模式指定的端口

然后在progress中打好断点，启动Debug，便可进入到断点调试中（如下图）

可以调试了~

最终结果：

F:\>java -cp F:\e\workspacetest\za\target\za-1.0.jar -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend
=y cn.zno.Main a b c
Listening for transport dt_socket at address: 8000
a
b
c

编译时的debug信息

如果不勾选line number 调试过程中会出现这种错误：
