java远程调试

idea2024创一个Spring Web项目springdemo1

使用maven-assembly-plugin插件打包成JAR文件

pom.xml参考如下

com.jk.springdemo1/controller/hellocontroller.java

package com.jk.springdemo1.Controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class hellocontroller{
    @RequestMapping(value="/",method = RequestMethod.GET)
    public String index(@RequestParam(value="name",required = false,defaultValue = "lihua") String name){
        System.out.println("hello");
        return "HelloWorld,"+name;
    }
}

idea终端输入mvn package开始打包

PS：可以把生成的jar文件放入lib目录下，右键->add as library，之后再项目其他位置import就可以用了。

下面把Springdemo1-0.0.1-SNAPSHOT.jar拖进kali虚拟机

idea添加Remote JVM Debug，Host填虚拟机ip

kali

java -version
sudo su
update-alternatives --config java     #切换jdk版本到jdk11
java -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:9988 -jar Springdemo1*

idea开启debug，本机访问网址，可以看到程序断在了断点处
