Axis2 released WebService (4) session Management of-webservice

First, the webservice added session management code, the use of the Messagecontext class and Servicecontext class. The code is as follows:

 PackageCom.hoo.service;ImportOrg.apache.axis2.context.MessageContext;ImportOrg.apache.axis2.context.ServiceContext; Public classLoginservice {//Login Method     Public BooleanLogin (String username,string password) {//instantiate a Messagecontext objectMessagecontext context =Messagecontext.getcurrentmessagecontext (); //gets the Servicecontext object that is used to manage the session object in a single webservice.Servicecontext CTX =Context.getservicecontext (); if("admin". Equals (UserName) && "123456". Equals (password)) {                        //adding attributes and values to the sessionCtx.setproperty ("username", UserName); Ctx.setproperty ("Password", password); Ctx.setproperty ("MSG", "Landing success"); return true; }Else{Ctx.setproperty ("MSG", "Login Failed"); return false; }    }         PublicString getloginmessage () {Messagecontext context=Messagecontext.getcurrentmessagecontext (); Servicecontext CTX=Context.getservicecontext (); //gets the value of the attribute in the sessionString msg = Ctx.getproperty ("username") + "," +ctx.getproperty ("MSG"); returnmsg; }}

The session information is saved here through the Messagecontext context to obtain the servicecontext context, and then through the SetProperty to save the session information, through the GetProperty to get session information.

The function of the session is to save the user's login status or session message when the WebService is logged in.

The WebService scope defaults to request, and it has three additional values, namely: Application, Soapsession, transportsession ; We can choose to use transportsession and application to implement session management for the same WebService class and cross-WebService classes, respectively.

Second, release WebService, modify the Services.xml file

After releasing WebService with Eclipse's Axis2 plugin, you need to open the Aar file with an extract file and locate the Services.xml file under the Web-inf folder.

In <service name="Loginservice" scope="Transportsession"> Add a description of the scope.

Third, write the request code of the WebService client

ImportJavax.xml.namespace.QName;ImportOrg.apache.axis2.AxisFault;Importorg.apache.axis2.addressing.EndpointReference;Importorg.apache.axis2.client.Options;Importorg.apache.axis2.rpc.client.RPCServiceClient; Public classloginwebserviceclient { Public Static voidMain (string[] args)throwsAxisfault {String target= "Http://localhost:8080/axis2/services/LoginService"; Rpcserviceclient Client=Newrpcserviceclient (); Options Options=client.getoptions (); //Open the support for the sessionOptions.setmanagesession (true); EndpointReference EPR=Newendpointreference (target);                Options.setto (EPR); //Name of functionQName QName =NewQName ("http://service.hoo.com", "Login"); //specify the method to invoke and pass the parameter data, and set the type of the return valueObject[] result = client.invokeblocking (QName,NewObject[] {"admin", "123456"},NewClass[] {Boolean.class }); System.out.println (result[0]); QName=NewQName ("http://service.hoo.com", "Getloginmessage"); Result= Client.invokeblocking (QName,NewObject[] {NULL},NewClass[] {String.class }); System.out.println (result[0]); }}

After execution, the results are as follows:

True

Admin, Login successful
