- Create new maven project, see Maven getting started. Add Jitpack maven repo into the project to be able using SingularityNet Java SDK artifacts:
<project>
<repositories>
<repository>
<id>jitpack.io</id>
<url>https://jitpack.io</url>
</repository>
</repositories>
</project>- Use
snet-sdk-maven-pluginto get service protobuf API within your project:
<project>
<properties>
<snet.sdk.java.version>master-SNAPSHOT</snet.sdk.java.version>
</properties>
<build>
<plugins>
<plugin>
<groupId>com.github.singnet.snet-sdk-java</groupId>
<artifactId>snet-sdk-maven-plugin</artifactId>
<version>${snet.sdk.java.version}</version>
<executions>
<execution>
<configuration>
<!-- service organization id -->
<orgId>snet</orgId>
<!-- service id -->
<serviceId>cntk-image-recon</serviceId>
<!-- API output dir -->
<outputDir>${project.build.directory}/proto</outputDir>
<!-- desired java package for classes generated -->
<javaPackage>io.singularitynet.client.cntk</javaPackage>
<!-- Ethereum RPC endpoint to use -->
<ethereumJsonRpcEndpoint>https://mainnet.infura.io/v3/e7732e1f679e461b9bb4da5653ac3fc2</ethereumJsonRpcEndpoint>
</configuration>
<goals>
<goal>get</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>- Add SingularityNet Java SDK as dependency:
<dependency>
<groupId>com.github.singnet.snet-sdk-java</groupId>
<artifactId>snet-sdk-java</artifactId>
<version>${snet.sdk.java.version}</version>
</dependency>-
Use
protobuf-maven-pluginto generate Java stubs of service API: -
Write Java client app using SDK API, see CntkImageRecognition.java as example:
// Create SDK configuration
Configuration config = Configuration.newBuilder()
.setEthereumJsonRpcEndpoint("https://mainnet.infura.io/v3/" /* + your infura project id */)
.setIdentityType(Configuration.IdentityType.PRIVATE_KEY)
.setIdentityPrivateKey(new byte[] { /* identity private key */ });
// Create SDK instance
Sdk sdk = new Sdk(config);
try {
// Choose payment strategy
PaymentStrategy paymentStrategy = new OnDemandPaymentChannelPaymentStrategy(sdk);
// Create new service client instance
ServiceClient serviceClient = sdk.newServiceClient("snet",
"cntk-image-recon", "default_group", paymentStrategy);
try {
// Get gRPC API stub
RecognizerBlockingStub stub = serviceClient.getGrpcStub(RecognizerGrpc::newBlockingStub);
// Call method
Input input = Input.newBuilder()
.setModel("ResNet152")
.setImgPath("https://d2z4fd79oscvvx.cloudfront.net/0027071_1_single_rose_385.jpeg")
.build();
Output output = stub.flowers(input);
System.out.println("Response received: " + output);
} finally {
// Shutdown service client
serviceClient.close();
}
} finally {
// Shutdown SDK
sdk.close();
}Integration testing is disabled by default. To run full build including integration tests use:
mvn install -DskipITs=false -P run-integration-environment
The command about automatically starts integration environment docker before running tests and stops after it. To start integration environment manually execute:
docker run -d \
--name java-sdk-integration-environment \
-p 5002:5002 -p 8545:8545 -p 7000:7000 \
singularitynet/java-sdk-integration-test-env:3.0.0
Then you can run build with integration testing using:
mvn install -DskipITs=false
Running integration tests is a time consuming process so to make fast build running unit tests only use:
mvn install
