JarCastingDropwizard HTTP/2 client
Dropwizard Integration with the Jetty HTTP/1.1 and HTTP/2 client
- Provides the ability to configure the client from a Dropwizard config.
- Instruments the client and register the metrics in the Dropwizard's
MetricsRegistry - The client is managed by the Dropwizard's environment and correctly cleans resources.
Example of the usage:
h2Client:
connectionTimeout: 1s
idleTimeout: 2s
private Http2ClientConfiguration h2Client;
@JsonProperty
public Http2ClientConfiguration getH2Client() {
return h2Client;
}
@JsonProperty
public void setH2Client(Http2ClientConfiguration h2Client) {
this.h2Client = h2Client;
}
HttpClient httpClient = new Http2ClientBuilder(environment)
.using(configuration.getH2Client())
.build("dropwizard-http2-golang");
// Call `httpClient.start()` if you want to use it before the server starts up.
Runtime dependencies
Don't forget to add an alpn-boot library to JVM’s bootpath:
-Xbootclasspath/p:/${user.home}/.m2/repository/org/mortbay/jetty/alpn/alpn-boot/${alpn-boot.version}/alpn-boot-${alpn-boot.version}.jar
The correct library version depends on a JVM version. Consult the Jetty ALPN guide for the reference.
