IDEA远程DEBUG

1、IDEA构建SpringBoot测试Demo

新建SpringBoot测试项目remote-debug,只需要web依赖支持即可;版本选用2.2.6.RELEASE(注意,别用2.5.1版本,有坑,亲测)

1.1、pom.xml

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.demo</groupId>
    <artifactId>remote-debug</artifactId>
    <version>v1.0</version>
    <name>remote-debug</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

1.2、application.yml

server:
  port: 8087
  servlet:
    context-path: /
  tomcat:
    uri-encoding: utf-8

1.3、新增Controller,提供接口测试

package com.java1234.controller;

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


@RestController
public class TestController {

    @PostMapping("/test")
    public String test(Integer id, String name) {
        System.out.println("id=" + id);
        System.out.println("name=" + name);
        if (id > 0) {
            return "success " + name;
        } else {
            return "fail";
        }
    }
}

1.4、启动项目使用postman测试

2、测试Demo项目配置支持远程调试

2.1、pom.xml里配置jvmArguments参数

<configuration>
  <jvmArguments>-Xdebug -Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=n</jvmArguments>
</configuration>

整体效果

 <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <jvmArguments>-Xdebug -Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=n</jvmArguments>
                </configuration>
            </plugin>
        </plugins>
    </build>

参数描述:

  • -Xdebug 通知JVM工作在DEBUG模式下;
  • -Xrunjdwp 通知JVM使用(Java debug wire protocol)运行调试环境。该参数同时包含了一系列的调试选项;
  • transport 指定了调试数据的传送方式,dt_socket是指用SOCKET模式,另有dt_shmem指用共享内存方式,其中,dt_shmem只适用于Windows平台;
  • address 调试服务器的端口号,客户端用来连接服务器的端口号;
  • server=y/n VM 是否需要作为调试服务器执行;
  • suspend=y/n 是否在调试客户端建立连接之后启动 VM;

3.IDEA打包JAR

4.启动jar并且带启动参数支持远程调试

4.1、把jar存储至随意目录

4.2、启动jar

4.3、启动命令

java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 -jar remote-debug-v1.0.jar

5.IDEA远程DEBUG配置

6.IDEA远程DEBUG调试
