# dubbo-example
[](https://travis-ci.org/gregwhitaker/dubbo-example)
An example of using [Apache Dubbo](https://dubbo.incubator.apache.org/) for microservice RPC.
This example starts both a Dubbo service and a restful web service. The Dubbo service returns `Hello World!` and `Goodbye!`
messages. The Dubbo service is accessed by making an HTTP call to the restful web service, which in turn calls the Dubbo service
and returns the message created by the Dubbo service.
## Projects
The following projects make up this example:
* [dubbo-example-api](dubbo-example-api) - Dubbo service API exposed by the provider
* [dubbo-example-consumer](dubbo-example-consumer) - Rest service that calls API exposed by the provider
* [dubbo-example-provider](dubbo-example-provider) - Dubbo service that implements the API
## Building the Example
Run the following Gradle command to build this example:
./gradlew clean build
## Running the Example
Follow the steps below to run the Dubbo example:
### Starting the Provider
1. In a new terminal, run the following command to start the provider:
./gradlew :dubbo-example-provider:run
If the provider starts successfully, you will see the following in the terminal:
2018-09-21 18:45:32.298 INFO 78749 --- [ main] dubbo.example.provider.Application : Started Application in 1.433 seconds (JVM running for 1.8)
2018-09-21 18:45:32.300 INFO 78749 --- [pool-1-thread-1] .d.c.e.AwaitingNonWebApplicationListener : [Dubbo] Current Spring Boot Application is await...
### Starting the Consumer
1. In a new terminal, run the following command to start the consumer:
./gradlew :dubbo-example-consumer:run
If the consumer starts successfully, you will see the following in the terminal:
2018-09-21 18:48:05.875 INFO 78789 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 8081 (http) with context path ''
2018-09-21 18:48:05.889 INFO 78789 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 8080 (http) with context path ''
2018-09-21 18:48:05.891 INFO 78789 --- [ main] dubbo.example.consumer.Application : Started Application in 3.757 seconds (JVM running for 4.127)
### Calling the Consumer
1. In a new terminal, run the following command to invoke the `hello` endpoint:
curl -v http://localhost:8080/hello?name=World
If the request was successful, you will receive a `Hello, World!` message:
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)
> GET /hello?name=World HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.54.0
> Accept: */*
>

< Content-Length: 13
< Date: Sat, 22 Sep 2018 01:49:59 GMT
<
* Connection #0 to host localhost left intact
Hello, World!
2. Run the following command to invoke the `goodbye` endpoint:
curl -v http://localhost:8080/goodbye
If the request was successful, you will receive a `Goodbye!` message:
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)
> GET /goodbye HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.54.0
> Accept: */*

< Content-Type: text/plain;charset=UTF-8
< Content-Length: 8
< Date: Sat, 22 Sep 2018 01:51:42 GMT
<
* Connection #0 to host localhost left intact
Goodbye!
