This repository shows how to implement a merchant server in order to successfully perform a [GooglePay](https://pay.google.com) payment using using our web-services. For more information about the web-services, please refer to the official documentation.
2+
3+
* This example uses [Spark](http://sparkjava.com/) framework that allows to create a simple server easily
4+
* In order to call the Web Services SOAP v5 to perform the payment, this example uses the existing [Web Services SDK](https://github.com/payzen/payzen-webservices-v5-sdk-java). Feel free to use your own solution based in JAX-WS, [CXF](https://github.com/apache/cxf), [Axis](https://github.com/apache/axis2-java), etc.

* [Getting started](#getting-started)
9+
* [What's included](#whats-included)
10+
* [Configuration](#configuration)
11+
12+
## Getting started
13+
14+
* Clone the repo: `git clone https://github.com/lyra/googlepay-payment-sparkjava-integration-sample.git`.
15+
* Set your shop data in the _app-configuration.properties_ file as described in [configuration instructions](#configuration).
16+
* Run `mvn package`, to build jar executable
17+
* Run `java -jar inApp-server-1.0-jar-with-dependencies.jar`
18+
19+
The application should have and output like this:
20+
21+
INFO org.eclipse.jetty.util.log - Logging initialized @698ms
22+
INFO spark.embeddedserver.jetty.EmbeddedJettyServer - == Spark has ignited ...
23+
INFO spark.embeddedserver.jetty.EmbeddedJettyServer - >> Listening on 0.0.0.0:9090
24+
INFO org.eclipse.jetty.server.Server - jetty-9.3.6.v20151106
25+
INFO org.eclipse.jetty.server.ServerConnector - Started ServerConnector@30946381{HTTP/1.1,[http/1.1]}{0.0.0.0:5678}
26+
INFO org.eclipse.jetty.server.Server - Started @1065ms
27+
28+
By default the application run on 9090 port. See [configuration instructions](#configuration) if you want to change this value.
29+

Server port can be easily configured via [Spark](http://sparkjava.com/) modifying the _Server.java_ file.
46+
47+
```java
48+
port(9090);
49+
```
50+
51+
All the shop configuration data must be set in the _app-configuration.properties_ file:
