Larry Safran 19eab29f8d compiler: Generate interfaces for services to implement (#9688 ) Introduce an AsyncService interface in the generated code and move the methods from <service>ImplBase to default implementation of the interface. * update pom files to allow java 1.8 * Add a bindService(<service>Async) method * Change TestServiceImpl to use the interface and include a bind method instead of extending TestServiceImplBase.		2023-02-15 10:33:44 -08:00

gRPC Hostname Example

The hostname example is a Hello World server whose response includes its hostname. It also supports health and reflection services. This makes it a good server to test infrastructure, like load balancing.

The example requires grpc-java to already be built. You are strongly encouraged to check out a git release tag, since there will already be a build of grpc available. Otherwise you must follow COMPILING.

Build the example

Build the hello-world example client. See the examples README
Build this server. From the grpc-java/examples/examples-hostname directory:

$ ../gradlew installDist

This creates the script build/install/hostname-server/bin/hostname-server that runs the example.

To run the hostname example, run:

$ ./build/install/hostname/bin/hostname-server

And in a different terminal window run the hello-world client:

$ ../build/install/examples/bin/hello-world-client

Maven

If you prefer to use Maven:

Build the hello-world example client. See the examples README
Run in this directory:

$ mvn verify
$ # Run the server (from the examples-hostname directory)
$ mvn exec:java -Dexec.mainClass=io.grpc.examples.hostname.HostnameServer
$ # In another terminal run the client (from the examples directory)
$ cd ..
$ mvn exec:java -Dexec.mainClass=io.grpc.examples.helloworld.HelloWorldClient

Bazel

If you prefer to use Bazel, run from the grpc-java/examples directory:

$ bazel build :hello-world-client example-hostname:hostname-server
$ # Run the server
$ ./bazel-bin/example-hostname/hostname-server
$ # In another terminal run the client
$ ./bazel-bin/hello-world-client
