com.google.inject.servlet.ServletModule

com.yammer.metrics.guice.servlet.AdminServletModule

All Implemented Interfaces:

com.google.inject.Module

public class AdminServletModule
extends com.google.inject.servlet.ServletModule

A guice servlet module that registers the AdminServlet via guice and also configures all healthchecks bound via guice to it. To use, install this module in your servlet module (or add as a separate module), and bind the health checks via a multi binder:

 install(new AdminServletModule());

 Multibinder<HealthCheck> healthChecksBinder = Multibinder.newSetBinder(binder(), HealthCheck.class);

 healthChecksBinder.addBinding().to(MyCoolHealthCheck.class);
 healthChecksBinder.addBinding().to(MyOtherCoolHealthCheck.class);
 
 

The module offers the same overloaded constructors to specifiy a custom JsonFactory and the uris for the healthcheck, metrics, etc. E.g.

 install(new AdminServletModule("/1.0/healthcheck", "/1.0/metrics", "/1.0/ping", "/1.0/threads"));
 
 

In order to use this module, you need the guice-servlet and guice-multibindings dependencies in addition to the normal guice dependency:

  <dependency>
   <groupId>com.google.inject</groupId>
   <artifactId>guice</artifactId>
   <version>3.0</version>
 </dependency>
 <dependency>
   <groupId>com.google.inject.extensions</groupId>
   <artifactId>guice-servlet</artifactId>
   <version>3.0</version>
 </dependency>
 <dependency>
   <groupId>com.google.inject.extensions</groupId>
   <artifactId>guice-multibindings</artifactId>
   <version>3.0</version>
 </dependency>
