Re: Google Guice & Jersey multiple URL patterns to same servlet while applying package filtering

[Fábio Uechi]

I need to do something very similar.

Did you find a workaround?

I am trying, using Jersey & Google Guice 3.0, to map 2 different URL patterns to the same servlet and each of these URL patterns to be applied to a different package in my project.

To be clear I am pasting part of the code below and I will also explain.

web.xml

<listener>

    <listener-class>com.abc.web.listeners.GuiceContextListener</listener-class>

</listener>

<filter>

    <filter-name>guiceFilter</filter-name>

    <filter-class>com.google.inject.servlet.GuiceFilter</filter-class>

</filter>

<filter-mapping>

    <filter-name>guiceFilter</filter-name>

    <url-pattern>/*</url-pattern>

</filter-mapping>

GuiceContextListener

public final class GuiceContextListener extends GuiceServletContextListener {

...

    private JerseyServletModule getJerseyServletModule() {

        JerseyServletModule jerseyModule = new JerseyServletModule() {

            @Override

            protected void configureServlets() {

                filter("/*").through(WebServerStateFilter.class);

                final Map<String, String> params = new HashMap<String, String>();

                StringBuilder sb = new StringBuilder();

                sb.append("com.abc.web.stats.services");

                params.put(PackagesResourceConfig.PROPERTY_PACKAGES, sb.toString());

                serve("/api/v1/*").with(GuiceContainer.class, params);

                final Map<String, String> params1 = new HashMap<String, String>();

                StringBuilder sb1 = new StringBuilder();

                sb1.append("com.abc.web.stats.otherservices");

                params1.put(PackagesResourceConfig.PROPERTY_PACKAGES, sb1.toString());

                serve("/api/*").with(GuiceContainer.class, params1);

            }

        }

    }

...

}

So basically I want:

URLs starting with "/api/v1/*" to be handled through servlet GuiceContainer by services in package "com.abc.web.stats.services"

URLs starting with "/api/*" to be handled through same servlet GuiceContainer by services in package "com.abc.web.stats.otherservices"

I used the code above but it does not seem to work, it seems that only the first "serve" call is taken into consideration so in this case only URLs matching "/api/v1/*" are served. I do not want to hardcode "v1" in my services since the version might change (to "v2") in the future.

Can somebody help me out?
