Hello,
i'm trying to follow the example at
http://code.google.com/p/google-guice/wiki/ServletModule
named "Using RequestScope".
I need to inject a username (a string) classes of my webapps.
So a added a servlet filter doing something like :
---8<---
httpRequest.setAttribute(Key.get(String.class,
Names.named("username")).toString(), my_username));
---8<---
and i added the filter mapping in my guice ServletModule
Then in a class requesting the username, an injected it as :
---8<---
private final Provider<String> username;
@Inject
public MyUserService(@Named("username") Provider<String> username) {
this.username = username
}
---8<---
but when the MyUserService class is instancied by guice, i get an
exception :
No implementation for java.lang.String annotated with
@com.google.inject.name.Named(value=username) was bound.
while locating com.google.inject.Provider<java.lang.String>
annotated with @com.google.inject.name.Named(value=username)
Any idea on how to inject the "Key" added to servlet attribute ?
Thanks
Anthony.
