JarCastingJCR support 4 dropwizard
A set of modules for connecting a Dropwizard app to a Java Content Repository
The set contains:
- dropwizard-jcr - some basic jcr interfaces and classes
- dropwizard-jackrabbit - support for jackrabbit (the reference implementation of jcr)
- dropwizard-jackrabbit-example - a basic example dropwizard app that uses the dropwizard
Usage
This module assumes you are including it in a Dropwizard 0.9.0 application with dropwizard-guice wiring.
Include as a maven dependency:
<dependency>
<groupId>com.github.justcoke</groupId>
<artifactId>dropwizard-jackrabbit</artifactId>
<version>${version.dropwizard-jackrabbit}</version>
</dependency>
Add configuration to your application's configuration class, like:
import javax.validation.Valid;
import javax.validation.constraints.NotNull;
import com.fasterxml.jackson.annotation.JsonProperty;
import io.dropwizard.Configuration;
import com.github.justcoke.dropwizard.jackrabbit.JackrabbitRepositoryFactory;
public class HelloWorldConfiguration extends Configuration {
@Valid
@NotNull
@JsonProperty
private JackrabbitRepositoryFactory repository = new JackrabbitRepositoryFactory();
public JackrabbitRepositoryFactory getRepository() {
return repository;
}
}
Add reasonable configuration options to your application YML file:
...
repository:
homeDir: <mandatory; path where to store the te repository>
configFile: <xml-configuration of the jcr; if not set built in defaultRepository.xml will be used>
...
Make sure your Guice wiring "provides" the Repository as a bean so you are able to inject it in your business code:
import java.io.IOException;
import javax.inject.Named;
import javax.jcr.Repository;
import javax.jcr.RepositoryException;
import com.google.inject.AbstractModule;
import com.google.inject.Provides;
public class HelloWorldModule extends AbstractModule {
...
@Provides
@Named("jcr")
public Repository provideRepository(HelloWorldConfiguration configuration) {
try {
return configuration.getRepository().build(null);
} catch (RepositoryException | IOException e) {
e.printStackTrace();
return null;
}
}
}
Finally in your application's main initialize() method, add your new HelloWorldModule to your guice bundle, for example:
import com.hubspot.dropwizard.guice.GuiceBundle;
private GuiceBundle<HelloWorldConfiguration> guiceBundle = null;
@Override
public void initialize(Bootstrap<HelloWorldConfiguration> bootstrap) {
// Guice
guiceBundle = GuiceBundle.<HelloWorldConfiguration> newBuilder().addModule(new HelloWorldModule())
.enableAutoConfig(getClass().getPackage().getName()).setConfigClass(HelloWorldConfiguration.class)
.build();
bootstrap.addBundle(guiceBundle);
}
Also have look at the dropwizard-jackrabbit-example.
