IDEA远程DeBug调试_idea 远程调试

2. 创建一个springboot项目

---

1、创建springboot工程

2、导入依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>cn.aopmin</groupId>
    <artifactId>debug_demo</artifactId>
    <version>1.0.0</version>
    <packaging>jar</packaging>

    <!--父工程-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.2</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>


    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <!--springboot web起步依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--hutool-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.8.12</version>
        </dependency>
    </dependencies>


    <build>
        <!--指定项目打完包之后的名称，xxx地方自定义-->
        <finalName>debug_demo</finalName>
        <plugins>
            <!--打包插件-->
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <excludes>
                        <exclude>
                            <groupId>org.projectlombok</groupId>
                            <artifactId>lombok</artifactId>
                        </exclude>
                    </excludes>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

3、修改服务端口号

server:
  port: 6633

4、编写controller接口

package cn.aopmin.controller;

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

import java.util.HashMap;
import java.util.Map;

/\*\*
 \* @author 白豆五
 \* @version 2023/06/28
 \* @since JDK8
 \*/
@RestController
@RequestMapping("/api/user")
public class UserController {


    // region 通过ID获取用户信息
    @PostMapping("/info")
    public String getInfo(Long userId) {
        // 匿名内部类方式构建map存放用户信息
        Map<String, Object> userInfo = new HashMap<String, Object>() {
            {
                put("userId", 129);
                put("userName", "白豆五");
                put("userAge", 18);
                put("userSex", "男");
            }
        };

        if (userId == userInfo.get(userInfo)) { //如果两个包装类型比值要用equals方法
            return "用户信息：" + userInfo.toString();
        }
        return "用户不存在";
    }
    //endregion
}

3. 将项目打包，并部署到虚拟机上

---

前提环境：别忘装JDK

1、将项目打包，上传到虚拟机的/tmp目录

2、切到/tmp目录，执行如下命令启动程序

java -jar -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005  zxx.jar

虚拟机IP地址：192.168.150.123，端口5005(别忘放行)，jar包名： debug_demo.jar

java -jar -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=192.168.150.123:5005  debug_demo.jar
Listening for transport dt_socket at address: 5005

4. 在IDEA中创建远程调试启动项
