Introduction

In this article, we will explore the process of enabling Open Telemetry in a Spring Boot application that utilizes Apache Camel for routing and integration. Open Telemetry is an open-source project that provides a standardized way of collecting and exporting telemetry data from applications. By integrating Open Telemetry with Spring Boot and Apache Camel, we can gain valuable insights into the performance and behavior of our application.

Prerequisites

Before we begin, ensure that you have the following prerequisites installed:

Java 11 or later
Maven 3.6 or later
Spring Boot 2.5 or later
Apache Camel 3.10 or later
Open Telemetry Collector 0.15 or later

pom.xml Configuration

To enable Open Telemetry in our Spring Boot application, we need to add the necessary dependencies to our pom.xml file. Here's an example of how to configure the dependencies:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;project xmlns=&quot;http://maven.apache.org/POM/4.0.0&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;
         xsi:schemaLocation=&quot;http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd&quot;&gt;
    &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
    &lt;groupId&gt;com.example&lt;/groupId&gt;
    &lt;artifactId&gt;open-telemetry-spring-boot-camel&lt;/artifactId&gt;
    &lt;version&gt;0.0.1-SNAPSHOT&lt;/version&gt;
    &lt;packaging&gt;jar&lt;/packaging&gt;
    &lt;name&gt;Open Telemetry Spring Boot Camel&lt;/name&gt;
    &lt;description&gt;Open Telemetry Spring Boot Camel&lt;/description&gt;
    &lt;properties&gt;
        &lt;java.version&gt;11&lt;/java.version&gt;
        &lt;maven.compiler.source&gt;${java.version}&lt;/maven.compiler.source&gt;
        &lt;maven.compiler.target&gt;${java.version}&lt;/maven.compiler.target&gt;
    &lt;/properties&gt;
    &lt;dependencies&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
            &lt;artifactId&gt;spring-boot-starter-web&lt;/artifactId&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;org.apache.camel&lt;/groupId&gt;
            &lt;artifactId&gt;camel-spring-boot&lt;/artifactId&gt;
            &lt;version&gt;3.10.0&lt;/version&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;io.opentelemetry&lt;/groupId&gt;
            &lt;artifactId&gt;opentelemetry-api&lt;/artifactId&gt;
            &lt;version&gt;1.4.0&lt;/version&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;io.opentelemetry&lt;/groupId&gt;
            &lt;artifactId&gt;opentelemetry-sdk&lt;/artifactId&gt;
            &lt;version&gt;1.4.0&lt;/version&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;io.opentelemetry&lt;/groupId&gt;
            &lt;artifactId&gt;opentelemetry-exporter-otlp&lt;/artifactId&gt;
            &lt;version&gt;1.4.0&lt;/version&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;io.opentelemetry&lt;/groupId&gt;
            &lt;artifactId&gt;opentelemetry-otlp&lt;/artifactId&gt;
            &lt;version&gt;1.4.0&lt;/version&gt;
        &lt;/dependency&gt;
    &lt;/dependencies&gt;
    &lt;build&gt;
        &lt;plugins&gt;
            &lt;plugin&gt;
                &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
                &lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
            &lt;/plugin&gt;
        &lt;/plugins&gt;
    &lt;/build&gt;
&lt;/project&gt;

Open Telemetry Configuration

To enable Open Telemetry in our Spring Boot application, we need to create a configuration class that will configure the Open Telemetry SDK. Here's an example of how to configure the Open Telemetry SDK:

import io.opentelemetry.api.GlobalOpenTelemetry;
import io.opentelemetry.api.trace.Tracer;
import io.opentelemetry.api.trace.TracerProvider;
import io.opentelemetry.exporter.otlp.OtlpGrpcExporter;
import io.opentelemetry.exporter.otlp.OtlpGrpcSpanExporter;
import io.opentelemetry.exporter.otlp.trace.OtlpTraceExporter;
import io.opentelemetry.sdk.OpenTelemetry;
import io.opentelemetry.sdk.trace.SdkTracerProvider;
import io.opentelemetry.sdk.trace.export.BatchSpanProcessor;
import io.opentelemetry.sdk.trace.export.SimpleSpanProcessor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class OpenTelemetryConfig {

    @Bean
    public TracerProvider tracerProvider() {
        return SdkTracerProvider.create();
    }

    @Bean
    public Tracer tracer() {
        return tracerProvider().getTracer("open-telemetry-spring-boot-camel");
    }

    @Bean
    public OtlpGrpcExporter otlpGrpcExporter() {
        return OtlpGrpcExporter.builder()
                .setEndpoint("http://localhost:55678")
                .build();
    }

    @Bean
    public OtlpTraceExporter otlpTraceExporter() {
        return OtlpTraceExporter.builder()
                .setEndpoint("http://localhost:55678")
                .build();
    }

    @Bean
    public BatchSpanProcessor batchSpanProcessor() {
        return BatchSpanProcessor.create(otlpGrpcExporter());
    }

    @Bean
    public SimpleSpanProcessor simpleSpanProcessor() {
        return SimpleSpanProcessor.create(otlpGrpcExporter());
    }

    @Bean
    public OpenTelemetry openTelemetry() {
        return OpenTelemetry.builder()
                .setTracerProvider(tracerProvider())
                .setResource(resource())
                .setSampler(sampler())
                .addSpanProcessor(batchSpanProcessor())
                .build();
    }

    @Bean
    public io.opentelemetry.api.common.Resource resource() {
        return io.opentelemetry.api.common.Resource.create(
                io.opentelemetry.api.common.Attributes.empty());
    }

    @Bean
    public io.opentelemetry.api.trace.Sampler sampler() {
        return io.opentelemetry.api.trace.Sampler.alwaysSample();
    }
}

Apache Camel Configuration

To enable Apache Camel in our Spring Boot application, we need to create a configuration class that will configure the Apache Camel context. Here's an example of how to configure the Apache Camel context:

import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class CamelConfig {

    @Bean
    public CamelContext camelContext() throws Exception {
        DefaultCamelContext camelContext = new DefaultCamelContext();
        camelContext.addRoutes(new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("direct:start")
                        .to("log:body")
                        .to("file://target/output");
            }
        });
        return camelContext;
    }
}

Open Telemetry Enabling in Apache Camel

To enable Open Telemetry in Apache Camel, we need to create a bean that will configure the Open Telemetry SDK for Apache Camel. Here's an example of how to configure the Open Telemetry SDK for Apache Camel:

import io.opentelemetry.api.GlobalOpenTelemetry;
import io.opentelemetry.api.trace.Tracer;
import io.opentelemetry.api.trace.TracerProvider;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.RouteDefinition;
import org.apache.camel.spi.RouteContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class OpenTelemetryCamelEnabler {

    @Autowired
    private TracerProvider tracerProvider;

    @Autowired
    private RouteContext routeContext;

    public void enableOpenTelemetry(RouteDefinition routeDefinition) {
        routeDefinition.before(routeContext -> {
            Tracer tracer = tracerProvider.getTracer("open-telemetry-spring-boot-camel");
            tracer.spanBuilder("camel-route").startSpan().makeCurrent();
        });
        routeDefinition.after(routeContext -> {
            Tracer tracer = tracerProvider.getTracer("open-telemetry-spring-boot-camel");
            tracer.spanBuilder("camel-route").endSpan();
        });
    }
}

Testing Open Telemetry

To test Open Telemetry, we can use the following test class:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context<br/>
