Dropwizard Ratelimit adds the ability to apply rate limiting directly in Dropwizard without any external services.
This project uses bucket4j and Hazelcast.
Pull requests are welcome!
This project works with Dropwizard 1.0.5.
Add the project to your dependencies. You will also need the following dependencies to your pom.xml:
<dependencies>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast</artifactId>
<version>3.7.5</version>
</dependency>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast-client</artifactId>
<version>3.7.5</version>
</dependency>
<dependency>
<groupId>com.github.vladimir-bukhtoyarov</groupId>
<artifactId>bucket4j-jcache</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>javax.cache</groupId>
<artifactId>cache-api</artifactId>
<version>1.0.0</version>
</dependency>
</dependencies>
Then, in your Dropwizard initialize method add the following:
@Override
public void initialize(Bootstrap<Configuration> bootstrap) {
long permitsPerPeriod = 100;
long period = 1;
TimeUnit timeUnit = TimeUnit.MINUTES;
RateLimitProvider rateLimitProvider = new HazelcastRateLimitProvider(
permitsPerSecond,
period,
timeUnit
);
bootstrap.addBundle(new RateLimitBundle(rateLimitProvider));
}
Finally, add the following annotation to your rate limited routes:
@GET
@Path("index")
@RateLimited(cost = 1)
Response getIndex() {
// etc.
