Using Guice with Jersey 2 (Part 2): guice-bridge library
The previous post “Using Guice with Jersey 2, without external librairies” proposed a trick to integrate Guice into Jersey2 dependency injection system (HK2) without helpers or libraries. In that post, I have also mentioned that none of the metionned external libraries work well for this integration, which lead to the necessity of that hack. At that point, I was not aware of HK2 guice-bridge, which is the solution proposed by HK2 to tackle the issues related to HK2 and guice integration. This post shows an example of guice-bridge usage.
Using HK2 guice-bridge:
Our Config class from the previous post becomes:
for readability purposes, I have encapsulated the logic for the bridge set up into the
initGuiceIntoHK2Bridge method. We can now get rid of the HK2toGuiceModule class.
As of the time this post is written, the guice-bridge seems to be the cleanest and simplest way of integrating guice into HK2 (and thus Jersey 2), and therefore it is the recommended method to use.
