Embedding elasticsearch Into Application

Comment

Elasticsearch fully supported the option to be run as part of the application,

within the same JVM process (the technique commonly referred as embedding). Although it is certainly not a recommended

practice, sometimes it was very useful and saves a lot of effort, for example during integration / system / component test runs.

@Configuration
public class ElasticsearchEmbeddedConfiguration {
private static class EmbeddedNode extends Node {
public EmbeddedNode(Settings preparedSettings) {
super(
InternalSettingsPreparer.prepareEnvironment(preparedSettings, null),
Collections.singletonList(Netty4Plugin.class)
);
}
}
@Bean(initMethod = "start", destroyMethod = "stop")
Node elasticSearchTestNode() throws NodeValidationException, IOException {
return new EmbeddedNode(
Settings
.builder()
.put(NetworkModule.TRANSPORT_TYPE_KEY, "netty4")
.put(NetworkModule.HTTP_TYPE_KEY, "netty4")
.put(NetworkModule.HTTP_ENABLED.getKey(), "true")
.put(Environment.PATH_HOME_SETTING.getKey(), home().getAbsolutePath())
.put(Environment.PATH_DATA_SETTING.getKey(), data().getAbsolutePath())
.build());
}
@Bean
File home() throws IOException {
return Files.createTempDirectory("elasticsearch-home-").toFile();
}
@Bean
File data() throws IOException {
return Files.createTempDirectory("elasticsearch-data-").toFile();
}
@PreDestroy
void destroy() throws IOException {
FileSystemUtils.deleteRecursively(home());

}
}
