Mac Idea Remote JVM Debug 远程断点调试

部署jar项目时，添加启动参数

• jdk8：java -jar -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9999 xxx.jar
• jdk8以上版本：java -jar -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:9999 xxx.jar

准备SpringBoot项目

准备一个接口

package com.example.demo.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @description:
 * @author: Alex
 * @create: 2023-11-07 23:08
 */
@RestController
@RequestMapping("/api/v1")
public class DemoController {
    @GetMapping("hi")
    public String hi() {
        int a = 1;
        System.out.println("a>>>" + a);
        int b = 2;
        System.out.println("b>>>" + b);
        int num = a + b;
        System.out.println("nun>>>>" + num);
        return "hello world";
    }
}
