文章目录

下载包

APM为v8.9.1
Agents为v8.10.0
如下图（示例）：
百度云盘分享：

提取码：2022

配置

数据库使用默认的H2数据库，我使用默认配置，暂时不作修改
application.yml的storage可以选择数据库
如下图（示例）：
如果需要修改访问端口可以在这里修改
如下图（示例）：
webapp的webapp.yml修改server.port即可，我这里还是用的默认的

启动运行

运行前需要保证电脑配置了JAVA_HOME
如下图（示例）：

双击文件直接运行
如下图（示例）：
访问http://127.0.0.1:8080
如下图（示例）：

idea配置运行skywalking的程序配置jvm参数

如下图（示例）：
①配置VM options(skywalking-agent.jar所在位置)：-javaagent:E:/skywalking/skywalking-agent/skywalking-agent.jar
注意事项：由于Skywalking 默认是不支持 Spring Cloud Gateway ，若为Cloud服务，需要将optional-plugins目录中最新的apm-spring-cloud-gateway*放入plugins目录中
②配置 Program arguments(Your_ApplicationName为当前的服务名称)：-Dskywalking.agent.service_name=Your_ApplicationName
③配置指向写入链路数据的服务器地址-Dskywalking.collector.backend_service=localhost:11800

创建spring-cloud-skywalking-demo项目

项目代码：https://gitee.com/java_wxid/java_wxid/tree/master/demo/spring-cloud-skywalking-demo
项目结构如下（示例）：

修改pom.xml

        </plugins>
    </build>

</project>

创建logback-spring.xml

代码如下（示例）：

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true"  debug="false">

    <springProperty scop="context" name="spring.application.name" source="spring.application.name" defaultValue=""/>
    <!--日志存放路径-->
    <property name="PATH" value="logs"/>

    <property name="FILE_NAME" value="$spring.application.name"/>

    <appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
            <layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout">

                </Pattern>
            </layout>
        </encoder>
    </appender>
    <!--trace-->
    <appender name="TRACE_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

        </encoder>
    </appender>

    <!--error-->

        <appender-ref ref="TRACE_FILE" />
        <appender-ref ref="ERROR_FILE" />
    </root>

</configuration>

创建application.yml

代码如下（示例）：

server:
  port: 8199

spring:
  application:
    name: springboot-skywalking-demo
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://139.224.137.74:3306/syncdemo?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false
    username: root
    password: ca0a997ee4770063

修改SpringCloudSkywalkingDemoApplication

代码如下（示例）：

package com.example.springcloudskywalkingdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.mybatis.spring.annotation.MapperScan;

@MapperScan("com.example.springcloudskywalkingdemo.dao")
@SpringBootApplication
public class SpringCloudSkywalkingDemoApplication 

    public static void main(String[] args) 
        SpringApplication.run(SpringCloudSkywalkingDemoApplication.class, args);

创建IndexController

代码如下（示例）：

package com.example.springcloudskywalkingdemo.controller;

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

/**
 * @author zhiwei Liao
 * @Description
 * @Date create in 2022/9/12 0012 21:03
 */
@RestController
public class IndexController 

    @RequestMapping("/")
    public String hello()
        return "hello fox";
    

    @RequestMapping("/notify")
    public String notify(@RequestBody Object obj)
        //TODO 告警信息，给技术负责人发短信，钉钉消息，邮件，微信通知等
        System.err.println(obj.toString());
        return "notify successfully";

创建ProfileController

代码如下（示例）：

package com.example.springcloudskywalkingdemo.controller;


import org.apache.skywalking.apm.toolkit.trace.Trace;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.concurrent.CountDownLatch;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.TimeUnit;

/**
 * @author zhiwei Liao
 * @Description
 * @Date create in 2022/9/12 0012 21:03
 */
@RestController
public class ProfileController 

    @RequestMapping("/profile")
    public String profile()
        process();
        return "success";
    

    @Trace
    private void process()
        ExecutorService executorService = Executors.newFixedThreadPool(2);
        CountDownLatch countDownLatch = new CountDownLatch(2);
        executorService.submit(new Runnable() 
            @Override
            public void run() 
                countDownLatch.countDown();
            
        );
        executorService.submit(new Runnable() 
            @Override
            public void run() 
               // countDownLatch.countDown();
            
        );
        try 
            countDownLatch.await(500, TimeUnit.MILLISECONDS);
         catch (InterruptedException e) 
            e.printStackTrace();

创建UserController

代码如下（示例）：

package com.example.springcloudskywalkingdemo.controller;

import com.example.springcloudskywalkingdemo.entity.User;
import com.example.springcloudskywalkingdemo.service.UserService;
import lombok.extern.slf4j.Slf4j;
import org.apache.skywalking.apm.toolkit.trace.TraceContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
import java.util.Optional;

/**
 * @author zhiwei Liao
 * @Description
 * @Date create in 2022/9/12 0012 21:03
 */
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController 

    @Autowired
    private UserService userService;

    @RequestMapping("/info/id")
    public User info(@PathVariable("id") Integer id)

        if(id==4)
            throw new IllegalArgumentException("参数异常");
        

        try 
            Thread.sleep(2000);
         catch (InterruptedException e) 
            e.printStackTrace();
        

        return userService.getById(id);
    

    @RequestMapping("/list")
    public List<User> list()
        //TraceContext可以绑定key-value
        TraceContext.putCorrelation("name", "liaozhiwei");
        Optional<String> op = TraceContext.getCorrelation("name");
        log.info("name =  ", op.get());
        //获取跟踪的traceId
        String traceId = TraceContext.traceId();
        log.info("traceId =  ", traceId);
        return userService.list();

创建UserMapper

代码如下（示例）：

package com.example.springcloudskywalkingdemo.dao;

import com.example.springcloudskywalkingdemo.entity.User;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
 * @author zhiwei Liao
 * @Description
 * @Date create in 2022/9/12 0012 21:03
 */
@Repository
public interface UserMapper 
    @Select("select * from user")
    List<User> list();

    @Select("select * from user where id=#id")
    User getById(Integer id);

创建User

代码如下（示例）：

package com.example.springcloudskywalkingdemo.entity;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

/**
 * @author zhiwei Liao
 * @Description
 * @Date create in 2022/9/12 0012 21:03
 */
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User 

    private Integer id;
    private String name;

创建UserService

代码如下（示例）：

package com.example.springcloudskywalkingdemo.service;

import com.example.springcloudskywalkingdemo.entity.User;
import java.util.List;

/**
 * @author zhiwei Liao
 * @Description
 * @Date create in 2022/9/12 0012 21:03
 */
public interface UserService 

    List<User> list();

    User getById(Integer id);

创建UserServiceImpl

代码如下（示例）：

package com.example.springcloudskywalkingdemo.service.impl;

import com.example.springcloudskywalkingdemo.dao.UserMapper;
import com.example.springcloudskywalkingdemo.entity.User;
import com.example.springcloudskywalkingdemo.service.UserService;
import org.apache.skywalking.apm.toolkit.trace.Tag;
import org.apache.skywalking.apm.toolkit.trace.Tags;
import org.apache.skywalking.apm.toolkit.trace.Trace;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;

/**
 * @author zhiwei Liao
 * @Description
 * @Date create in 2022/9/12 0012 21:03
 */
@Service
public class UserServiceImpl implements UserService 
    @Autowired
    private UserMapper userMapper;

    @Trace
    @Tag(key = "list", value = "returnedObj")
    @Override
    public List<User> list()
        return userMapper.list();
    

    @Trace
    @Tags(@Tag(key = "param", value = "arg[0]"),
            @Tag(key = "user", value = "returnedObj"))
    @Override
    public User getById(Integer id)
        return userMapper.getById(id);
