# Library Instrumentation for Java HTTP Client
|
|
|
|
Provides OpenTelemetry instrumentation for [Java HTTP Client](https://openjdk.org/groups/net/httpclient/intro.html).
|
|
|
|
## Quickstart
|
|
|
|
### Add these dependencies to your project
|
|
|
|
Replace `OPENTELEMETRY_VERSION` with the [latest
|
|
release](https://search.maven.org/search?q=g:io.opentelemetry.instrumentation%20AND%20a:opentelemetry-java-http-client).
|
|
|
|
For Maven, add to your `pom.xml` dependencies:
|
|
|
|
```xml
|
|
<dependencies>
|
|
<dependency>
|
|
<groupId>io.opentelemetry.instrumentation</groupId>
|
|
<artifactId>opentelemetry-java-http-client</artifactId>
|
|
<version>OPENTELEMETRY_VERSION</version>
|
|
</dependency>
|
|
</dependencies>
|
|
```
|
|
|
|
For Gradle, add to your dependencies:
|
|
|
|
```groovy
|
|
implementation("io.opentelemetry.instrumentation:opentelemetry-java-http-client:OPENTELEMETRY_VERSION")
|
|
```
|
|
|
|
### Usage
|
|
|
|
The instrumentation library contains an `HttpClient` wrapper that provides OpenTelemetry-based spans
|
|
and context propagation.
|
|
|
|
```java
|
|
import io.opentelemetry.api.OpenTelemetry;
|
|
import io.opentelemetry.instrumentation.httpclient.JavaHttpClientTelemetry;
|
|
import java.net.http.HttpClient;
|
|
|
|
import java.util.concurrent.ExecutorService;
|
|
|
|
public class JavaHttpClientConfiguration {
|
|
|
|
//Use this HttpClient implementation for making standard http client calls.
|
|
public HttpClient createTracedClient(OpenTelemetry openTelemetry) {
|
|
return JavaHttpClientTelemetry.builder(openTelemetry).build().newHttpClient(createClient());
|
|
}
|
|
|
|
//your configuration of the Java HTTP Client goes here:
|
|
private HttpClient createClient() {
|
|
return HttpClient.newBuilder().build();
|
|
}
|
|
}
|
|
```
