Guice Basic use, Guice integration guice-servlet,web scope annotations (vi)

The Guice servlet provides several more useful web scopes, similar to those provided by the session,request of the traditional servlet.

The web scope provided by the Guice servlet is as follows:

[Email protected]

[Email protected]

[Email protected]

[Email protected]

Examples are as follows:

1  Packagecom.ming.user.action;2 3 Importcom.google.inject.servlet.RequestScoped;4 5 /**6 * Similar to the time we requested to save the value in this access7  * @authorMingge8  *9  */Ten @RequestScoped One  Public classRequstscope { A  -      -}

1  Packagecom.ming.user.action;2 3 ImportCom.google.inject.Inject;4 ImportCom.google.inject.Provider;5 6  Public classRequstscopetest {7 8 @Inject9     PrivateProvider<requstscope> requst=NULL;Ten      One  ARequstscope A=requst.get ();//Use this method to fetch the value of this range -      -}

Examples are as follows:

1  Packagecom.ming.user.action;2 3 Importcom.google.inject.servlet.SessionScoped;4 5 @SessionScoped6  Public classSessionscope {7 8     Private intCount=0;9 Ten      Public intGetCount () { One         returncount; A     } -  -      Public voidSetCount (intcount) { the          This. Count =count; -     } -      -      +}

1  Packagecom.ming.user.action;2 3 ImportCom.google.inject.Inject;4 ImportCom.google.inject.Provider;5 6  Public classSessionscopetest {7 8 @Inject9     PrivateProvider<sessionscope> session=NULL;Ten      One  ASessionscope A=session.get ();//Use this method to fetch the value of this range -      -     voidTest () { theA.setcount (2); -     } -}

Examples are as follows:

1 @Inject 2 @RequestParameters 3 Private Provider<map<string, string[]>> Reqparammapprovider;

Guice servlet is still relatively useful, if you choose to use the servlet to develop the proposal to use it.
