# OpenTelemetry Agentless | Sentry for Spring

If you do not want to use our recommended [Java Agent](https://docs.sentry.io/platforms/java/guides/spring/opentelemetry/setup/agent.md), we also offer a dependency that allows you to use OpenTelemetry with Sentry.

## [Install](https://docs.sentry.io/platforms/java/guides/spring/opentelemetry/setup/agentless.md#install)

In addition to your typical Sentry dependencies, you will need to add `sentry-opentelemetry-agentless` as a dependency:

```groovy
implementation 'io.sentry:sentry-opentelemetry-agentless:8.51.0'
```

*Other available variations of the above snippet: Maven*

Please note, if you're using Spring Boot, there's a separate `sentry-opentelemetry-agentless-spring` dependency. You can [find out more here](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agentless.md).

## [OpenTelemetry Dependency Alignment](https://docs.sentry.io/platforms/java/guides/spring/opentelemetry/setup/agentless.md#opentelemetry-dependency-alignment)

Sentry's Java OpenTelemetry integrations are tested with a specific OpenTelemetry dependency set. If your application also imports a BOM that manages OpenTelemetry versions, such as Spring Boot dependency management, it can override transitive OpenTelemetry dependencies and create a mixed OpenTelemetry classpath.

Import `io.sentry:sentry-opentelemetry-bom` manually when another BOM manages OpenTelemetry versions in your application.

When using Gradle with Spring dependency management, import Sentry's OpenTelemetry BOM:

```groovy
dependencyManagement {
    imports {
        mavenBom 'io.sentry:sentry-opentelemetry-bom:8.51.0'
    }
}
```

When using Maven, import Sentry's OpenTelemetry BOM before `spring-boot-dependencies`:

```xml
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.sentry</groupId>
            <artifactId>sentry-opentelemetry-bom</artifactId>
            <version>8.51.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>${spring-boot.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
```

If you use `spring-boot-starter-parent`, import Sentry's OpenTelemetry BOM in the child POM's `dependencyManagement` section.

## [Usage](https://docs.sentry.io/platforms/java/guides/spring/opentelemetry/setup/agentless.md#usage)

You'll have to configure both OpenTelemetry and Sentry to see transactions in Sentry and have errors linked to transactions created by OpenTelemetry.

#### [Initializing OpenTelemetry](https://docs.sentry.io/platforms/java/guides/spring/opentelemetry/setup/agentless.md#initializing-opentelemetry)

Our `sentry-opentelemetry-agentless` dependency also adds `opentelemetry-sdk-extension-autoconfigure` which takes care of configuring OpenTelemetry to work with Sentry. You can configure it using `AutoConfiguredOpenTelemetrySdk`:

```java
import io.opentelemetry.sdk.autoconfigure.AutoConfiguredOpenTelemetrySdk;

AutoConfiguredOpenTelemetrySdk.builder()
  .setResultAsGlobal()
  .addPropertiesSupplier(() -> {
    final Map<String, String> properties = new HashMap<>();
    properties.put("otel.logs.exporter", "none");
    properties.put("otel.metrics.exporter", "none");
    properties.put("otel.traces.exporter", "none");
    return properties;
  })
  .build();
```

*Other available variations of the above snippet: Kotlin*

#### [Initializing Sentry](https://docs.sentry.io/platforms/java/guides/spring/opentelemetry/setup/agentless.md#initializing-sentry)

You can initialize Sentry as usual, fore example, by calling `Sentry.init`:

```java
import io.sentry.Sentry;

Sentry.init(options -> {
  options.setDsn("https://<key>@o<orgId>.ingest.sentry.io/<projectId>");
  options.setTracesSampleRate(1.0);
});
```
