Axis2 calls WebService several ways

There are three main ways of doing this:

First RPC mode, no client code generated

Second,document mode, do not generate client code

Third, use the wsdl2java tool to generate a client-side call

Java code:

The third parameter represents the class object of the return value type of the WebService method, and the parameter type is class[].            If the called WebService method does not return a value, the method should use the Invokerobust method with only two parameters, which have the same meaning as the first two parameters of the Invokeblocking method.       When you create a QName object, the first parameter of the constructor method of the QName class represents the namespace name of the WSDL file, which is the targetnamespace attribute value of the <wsdl:definitions> element. *       */       Public Static voidtestrpcclient () {Try {          //axis1 Service Side//String url = "http://localhost: 8080/stockquote/services/stockquoteservicesoap11port?wsdl "; //Axis2 Service SideString url = "HTTP://LOCALHOST:8080/AXIS2SERVERDEMO/SERVICES/STOCKQUOTESERVICE?WSDL"; //call WebService using RPC modeRpcserviceclient serviceclient =Newrpcserviceclient (); //Specifies the URL to call WebServiceEndpointReference Targetepr =Newendpointreference (URL); Options Options=serviceclient.getoptions (); //Determine destination service addressOptions.setto (TARGETEPR); //determining the Calling methodOptions.setaction ("Urn:getprice"); /*** Specify the GetPrice method to invoke and the namespace of the WSDL file * If the WebService service driven by Axis2 writing * The problem caused by the namespace inconsistency * org.apache.axis2.AxisFault:java.lang.RuntimeException:Unexpected subelement arg0*/QName QName=NewQName ("Http://quickstart.samples/xsd", "GetPrice"); //specifying the parameter value of the GetPrice methodobject[] Parameters =NewObject[] {"13" }; //class object specifying the data type of the GetPrice method return valueclass[] Returntypes =NewClass[] {Double.class }; //call method One pass parameter, invoke service, get service return result setomelement element =serviceclient.invokeblocking (QName, parameters); //It is worth noting that the returned result is an XML string encapsulated by the Omelement object. //we can apply it flexibly, and below I take the first element value and print it.

WSDL2Java is used to generate the appropriate server-side and client code generation tools based on WSDL.
The command line format is: WSDL2Java [options]-uri <url or path>: a URL or path to A WSDL

For example:

Wsdl2java-uri http://localhost:8080/cxfService_0617/services/Hellows?wsdl-s-O build\client

The options that are commonly used are as follows:
-O <path>: Specifies the output path of the generated code
-A: Generate code for asynchronous patterns
-S: Generate code for synchronous mode
-P <pkg>: Specify the package name for the code
-L <languange>: Used language (java/c) default is Java
-T: Generating test Cases for code
-SS: Generate server-side code is not generated by default
-SD: Generate service description file Services.xml, used only with-SS
-D <databinding>: Specify Databingding, for example, Adb,xmlbean,jibx,jaxme and Jaxbri
-G: Generate the server and client code
-PN <port_name>: When there are multiple ports in the WSDL, specify one of the ports
-SN <serv_name>: Select a service in the WSDL
-U: Expand the class of data-binding
-R <path>: Specify a repository for code generation
-ssi: Implementing code Generation Interface classes for the service side
-S: Specify the storage path for the generated source code
-r: Specify a storage path for the generated resources
–nobuildxml: Build.xml file not generated in output
–NOWSDL: The WSDL file is not generated in the resources directory
–nomessagereceiver: Do not generate Messagereceiver class
