本文介绍了如何在Go服务端应用中使用OpenTelemetry和Jaeger进行追踪，包括设置TracerProvider、GORM集成OpenTelemetry插件以及客户端发起请求时携带追踪信息。

服务端代码：

package main

import (
   "GoStart/telemetry/ch03/server/model"
   "github.com/gin-gonic/gin"
   "go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin"
   "go.opentelemetry.io/otel"
   "go.opentelemetry.io/otel/attribute"
   "go.opentelemetry.io/otel/exporters/jaeger"
   "go.opentelemetry.io/otel/propagation"
   "go.opentelemetry.io/otel/sdk/resource"
   "go.opentelemetry.io/otel/sdk/trace"
   semconv "go.opentelemetry.io/otel/semconv/v1.12.0"
   "gorm.io/driver/mysql"
   "gorm.io/gorm"
   "gorm.io/gorm/logger"
   "gorm.io/gorm/schema"
   "gorm.io/plugin/opentelemetry/tracing"
   "log"
   "os"
   "time"
)

var tp *trace.TracerProvider

const (
   TRACE_NAME = "mxshop-otel"
)

func tracerProvider() error {
   
   
   url := "http://192.168.66.130:14268/api/traces"
   jexp, err := jaeger.New(jaeger.WithCollectorEndpoint(jaeger.WithEndpoint(url)))
   if err != nil {
   
   
      panic(err)
   }
   tp = trace.NewTracerProvider(
      trace.WithBatcher(jexp),
      trace.WithResource(
         resource.NewWithAttributes(
            semconv.SchemaURL,
            semconv.ServiceNameKey.String("mxshop-user"),
            attribute.String("environment", "dev"),
            attribute.Int("ID", 1),
         ),
      ),
   )
   otel.SetTracerProvider(tp)
   otel.SetTextMapPropagator(propagation.NewCompositeTextMapPropagator(propagation.TraceContext{
   
   }, propagation.Baggage{
   
   }))
   return nil
}
func Server(c *gin.Context) {
   
   
	dsn := "root:123456@tcp(127.0.0.1:3306)/mxshop_user_srv?charset=utf8mb4&parseTime=True&loc=Local"

	newLogger := logger.New(
		log.New(os.Stdout,
