问题 I'm writing a JUL logging Handler and I'd like to augment the logged messages with information about the current request, if we're currently handling a request. To accomplish this, I've injected a Provider<Thing> into the Handler , where Thing is @RequestScoped . However, calling provider.get() throws an OutOfScopeException if the logging happens while we're not handling a request. I feel like catching the OutOfScopeException would be bad form. Is there a better way to determine whether or

由 倖福魔咒の 提交于 2019-12-25 03:05:27
问题 I am using jersey-guice to set up all my Jersey 1 resources using a bunch of Guice (Servlet)Modules. I have written a custom ViewProcessor ( CustomViewProcessor ) that relies on a configuration object, that I want to be injected into it using Guice. This CustomViewProcessor should be picked up and used by Jersey every time it needs one. How do I tell Jersey to fetch a Guice-created CustomViewProcessor instance whenever it needs a ViewProcessor ? I want to set all this up within my Guice

Injecting dependencies to ServletContextListener with Guice

由 喜欢而已 提交于 2019-12-22 05:58:52
问题 Since ServletContextListener is created by the server, not by Guice I can't find a way to make it work together. How do I get guice injector at ServletContextListener?

Configuring Apache Shiro with Google Guice Servlet

由 空扰寡人 提交于 2019-12-04 10:51:09
问题 I'm starting to use Guice/Shiro instead of Spring/Spring Security. I have looked examples from Shiro site, and all configuration examples are made as INI-file examples. Is it possible to configure Shiro in plain Java, as Guice Servlets are meant to be configured? 回答1: Yes it is possible, but requires some glue code if you want Guice to create your Realms.
