Oracle NoSQL Database SDK for Spring Data
About
Oracle NoSQL SDK for Spring Data provides a Spring Data implementation module to connect to an Oracle NoSQL Database cluster or to Oracle NoSQL Cloud Service .
Requirements
Java versions 17 and higher are supported.
Installation
The Oracle NoSQL SDK for Spring Data can be included in a project in 2 ways:
Install as a Project Dependency
This dependency can be used to include the SDK and its dependencies in your project. The version changes with each release.
<dependency>
<groupId>com.oracle.nosql.sdk</groupId>
<artifactId>spring-data-oracle-nosql</artifactId>
<version>2.0.0</version>
</dependency>
Optionally, the packages can be manually installed in a local maven repository by
downloading from
releases page, and
running the following command (-sources and -javadoc files are optional):
mvn install:install-file \
-DpomFile=spring-data-oracle-nosql-x.y.z.pom \
-Dfile=spring-data-oracle-nosql-x.y.z.jar \
-Dsources=spring-data-oracle-nosql-x.y.z-sources.jar \
-Djavadoc=spring-data-oracle-nosql-x.y.z-javadoc.jar
Download from GitHub
You can download the Oracle NoSQL SDK for Spring Data as an archive from
GitHub. The archive
contains the runtime library and its dependencies, examples, and
API documentation.
Documentation
See Oracle NoSQL SDK for Spring Data javadoc for the latest API documentation. See Spring Data SDK Developers Guide for examples and additional details on the SDK.
General documentation about the Oracle NoSQL Database Cloud Service, Oracle NoSQL Database and Spring Data SDK
Developers Guide can be found in these locations:
Oracle NoSQL Database Cloud Service
Oracle NoSQL Database On Premise
Changes
See CHANGELOG for changes in each release.
Usage
The example below also requires an additional dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<version>3.1.2</version>
</dependency>
Define an AppConfig class that provides a nosqlDBConfig bean that returns an
Oracle NoSQL DB configuration:
package org.example.app;
import com.oracle.nosql.spring.data.config.AbstractNosqlConfiguration;
import com.oracle.nosql.spring.data.config.NosqlDbConfig;
import com.oracle.nosql.spring.data.repository.config.EnableNosqlRepositories;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import oracle.nosql.driver.kv.StoreAccessTokenProvider;
@Configuration
@EnableNosqlRepositories
public class AppConfig extends AbstractNosqlConfiguration {
@Bean
public NosqlDbConfig nosqlDbConfig() {
return new NosqlDbConfig(
"localhost:8080", // endpoint URL
new StoreAccessTokenProvider()); // AuthorizationProvider
Note: Depending on individual scenario use the appropriate AuthorizationProvider:
For cloud configuration use the following example or see
documentation:
new oracle.nosql.driver.iam.SignatureProvider(
tenantId, // OCID
userId, // OCID
fingerprint, // String
File privateKeyFile,
char[] passphrase)
For cloud configuration when application is running in the same region
use instance principal authentication. This requires a one-time
setup.
oracle.nosql.driver.iam.SignatureProvider.createWithInstancePrincipal()
For cloud simulator use:
com.oracle.nosql.spring.data.NosqlDbFactory.CloudSimProvider.getProvider()
For on-prem configuration use one of the following examples or see
documentation.
For unsecure example:
new oracle.nosql.driver.kv.StoreAccessTokenProvider()
For secure example use:
new oracle.nosql.driver.kv.StoreAccessTokenProvider("username", "password".toCharArray())
Note: For convenience one can use the following
com.oracle.nosql.spring.data.NosqlDbConfig methods:
for cloud: NosqlDbConfig.createCloudConfig("endpoint", configFile);
for cloud simulator: NosqlDbConfig.createCloudSimConfig("endpoint");
for on-prem unsecure store: NosqlDbConfig.createProxyConfig("endpoint");
for on-prem secure store: NosqlDbConfig.createProxyConfig("endpoint", user, password);
Define the entity class:
package org.example.app;
import com.oracle.nosql.spring.data.core.mapping.NosqlId;
public class Customer {
@NosqlId(generated = true)
long customerId;
String firstName;
String lastName;
@Override
public String toString() {
return "Customer{" +
"customerId=" + customerId +
", firstName='" + firstName + '\'' +
", lastName='" + lastName + '\'' +
'}';
Declare a repository that extends NosqlRepository:
package org.example.app;
import com.oracle.nosql.spring.data.repository.NosqlRepository;
public interface CustomerRepository
extends NosqlRepository<Customer, Long>
Iterable<Customer> findByLastName(String lastname);
Write the main application class. This requires adding dependencies to org
.springframework.boot:spring-boot and org.springframework
.boot:spring-boot-autoconfigure.
package org.example.app;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
@SpringBootApplication
public class App implements CommandLineRunner
@Autowired
private CustomerRepository repo;
public static void main( String[] args )
ConfigurableApplicationContext
ctx = SpringApplication.run(App.class, args);
SpringApplication.exit(ctx, () -> 0);
ctx.close();
System.exit(0);
@Override
public void run(String... args) throws Exception {
repo.deleteAll();
Customer s1 = new Customer();
s1.firstName = "John";
s1.lastName = "Doe";
repo.save(s1);
System.out.println("\nsaved: " + s1); // customerId contains generated value
Customer s2 = new Customer();
s2.firstName = "John";
s2.lastName = "Smith";
repo.save(s2);
System.out.println("\nsaved: " + s2); // customerId contains generated value
System.out.println("\nfindAll:");
Iterable<Customer> customers = repo.findAll();
for (Customer s : customers) {
System.out.println(" Customer: " + s);
System.out.println("\nfindByLastName: Smith");
customers = repo.findByLastName("Smith");
for (Customer s : customers) {
System.out.println(" Customer: " + s);
Build and run the example code
Example code requires an Oracle NoSQL DB instance and a local http proxy running
on port 8080.
Start a kvlite instance with helperHosts "localhost:5000":
java -jar /path_to/kvstore.jar kvlite -root kvroot -host localhost -port 5000 -store kvstore -secure-config disable &
Start http proxy with endpoint URL "localhost:8080":
java -jar /path_to/httpproxy.jar -storeName kvstore -httpPort 8080 -helperHosts localhost:5000 -verbose true &
Execute the example code:
mvn exec:java -Dexec.mainClass="org.example.app.App"
To log the internally generated queries, one has to enable the debug level by
adding following logging flag:
mvn exec:java -Dexec.mainClass="org.example.app.App" -Dlogging.level.com.oracle.nosql.spring.data=DEBUG
Run unit tests
Running tests require a running store and proxy. The test.serverType and
test.endpoint system properties must be specified.
mvn test -Dtest.serverType=onprem -Dtest.endpoint=http://127.0.0.1:8080
By default, if no option is specified, onprem serverType and http://127.0.0
.1:8080 endpoint is assumed.
Tests can be also be run on:
onprem:
mvn -B -Ptest-onprem test -DargLine="-Dtest.endpoint=$ONPREM_ENDPOINT"
onprem-secure:
Must specify the user, password, trustfile and trust file access password.
mvn -B -Ptest-onprem-secure test -DargLine="-Dtest.endpoint=$ONPREM_SEC_ENDPOINT -Dtest.user=$DRIVER_USER -Dtest.trust=$DRIVER_TRUST_FILE -Dtest.password=$DRIVER_PASS -Dtest.trust.password=$DRIVER_TRUST_PASS"
cloudsim:
mvn -B -Ptest-cloudsim test -DargLine="-Dtest.endpoint=$CLOUDSIM_ENDPOINT"
