# Library Instrumentation for Spring Web MVC version 5.3 and higher
|
|
|
|
Provides OpenTelemetry instrumentation for Spring WebMVC controllers.
|
|
|
|
## Quickstart
|
|
|
|
### Add these dependencies to your project.
|
|
|
|
Replace `SPRING_VERSION` with the version of spring you're using.
|
|
- `Minimum version: 5.3`
|
|
|
|
Replace `OPENTELEMETRY_VERSION` with the [latest
|
|
release](https://search.maven.org/search?q=g:io.opentelemetry.instrumentation%20AND%20a:opentelemetry-spring-webmvc-5.3).
|
|
|
|
For Maven add the following to your `pom.xml`:
|
|
|
|
```xml
|
|
<dependencies>
|
|
<!-- OpenTelemetry instrumentation -->
|
|
<dependency>
|
|
<groupId>io.opentelemetry.instrumentation</groupId>
|
|
<artifactId>opentelemetry-spring-webmvc-5.3</artifactId>
|
|
<version>OPENTELEMETRY_VERSION</version>
|
|
</dependency>
|
|
|
|
<!-- OpenTelemetry exporter -->
|
|
<!-- replace this default exporter with your OpenTelemetry exporter (ex. otlp/zipkin/jaeger/..) -->
|
|
<dependency>
|
|
<groupId>io.opentelemetry</groupId>
|
|
<artifactId>opentelemetry-exporter-logging</artifactId>
|
|
<version>OPENTELEMETRY_VERSION</version>
|
|
</dependency>
|
|
|
|
<!-- required to instrument Spring WebMVC -->
|
|
<!-- this artifact should already be present in your application -->
|
|
<dependency>
|
|
<groupId>org.springframework</groupId>
|
|
<artifactId>spring-webmvc</artifactId>
|
|
<version>SPRING_VERSION</version>
|
|
</dependency>
|
|
|
|
</dependencies>
|
|
```
|
|
|
|
For Gradle add the following to your dependencies:
|
|
|
|
```groovy
|
|
|
|
// OpenTelemetry instrumentation
|
|
implementation("io.opentelemetry.instrumentation:opentelemetry-spring-webmvc-5.3:OPENTELEMETRY_VERSION")
|
|
|
|
// OpenTelemetry exporter
|
|
// replace this default exporter with your OpenTelemetry exporter (ex. otlp/zipkin/jaeger/..)
|
|
implementation("io.opentelemetry:opentelemetry-exporter-logging:OPENTELEMETRY_VERSION")
|
|
|
|
// required to instrument Spring WebMVC
|
|
// this artifact should already be present in your application
|
|
implementation("org.springframework:spring-webmvc:SPRING_VERSION")
|
|
```
|
|
|
|
### Features
|
|
|
|
#### `SpringWebMvcTelemetry`
|
|
|
|
`SpringWebMvcTelemetry` enables creating OpenTelemetry server spans around HTTP requests processed
|
|
by the Spring servlet container.
|
|
|
|
##### Usage in Spring Boot
|
|
|
|
Spring Boot allows servlet `Filter`s to be registered as beans:
|
|
|
|
```java
|
|
import io.opentelemetry.api.OpenTelemetry;
|
|
import io.opentelemetry.instrumentation.spring.webmvc.v5_3.SpringWebMvcTelemetry;
|
|
import javax.servlet.Filter;
|
|
import org.springframework.context.annotation.Bean;
|
|
import org.springframework.context.annotation.Configuration;
|
|
|
|
@Configuration
|
|
public class SpringWebMvcTelemetryConfiguration {
|
|
|
|
@Bean
|
|
public Filter telemetryFilter(OpenTelemetry openTelemetry) {
|
|
return SpringWebMvcTelemetry.create(openTelemetry).createServletFilter();
|
|
}
|
|
}
|
|
```
|
|
|
|
