| JAX-RS OpenTracing/Jaeger/Apache Camel Tracing Demo |
| ================= |
| |
| The demo shows a basic usage of OpenTracing API + Jaeger distributed tracer |
| across multiple distributed REST-based components. It consists of HTTP route |
| defined using Apache Camel, which forwards the request to JAX-RS 2.0 (JSR-339) |
| service, backed by Apache CXF. The demo also contains a JAX-RS 2.0 (JSR-339) |
| client which initiates the connection to the Apache Camel HTTP route. The |
| following REST(ful) endpoints are available: |
| |
| - GET to http://0.0.0.0:8084/catalog |
| - GET to http://localhost:8080/services/books |
| |
| To collect the traces, please run Jaeger distributed tracer components, the |
| simplest way would be using Docker: |
| |
| docker run --rm -it --network=host -p 16686:16686 -p 14268:14268 jaegertracing/all-in-one |
| |
| The following sample traces should be available in Jaeger UI (available |
| be default at http://localhost:16686/search): |
| |
| +- cxf-client GET http://localhost:8084/catalog |
| +- camel-server GET |
| +- camel-server GET |
| +- cxf-service GET /services/books |
| |
| Building and running the demo using Maven |
| --------------------------------------- |
| |
| From the base directory of this sample (i.e., where this README file is |
| located), the Maven pom.xml file can be used to build and run the demo. |
| |
| Using either UNIX or Windows: |
| |
| mvn install |
| mvn -Pcamel-server (from one command line window) |
| mvn -Pcxf-server (from one command line window) |
| mvn -Pclient (from a third command line window) |
| |
| To remove the target dir, run mvn clean". |
