JAX-WS and CXF implementation of Web Service

There are many ways to implement a WEB service, this article describes the implementation of JAX-WS (Pure Java), and then generates JavaBean from the CXF tool.

　　

The first step: Create a Java project, write the Calservice interface, which is the interface that provides the Web service.

1  PackageCom.fx.inf;2 3 ImportJavax.jws.WebMethod;4 ImportJavax.jws.WebService;5 6 //Mark Service Endpoint Interface (SEI)7 @WebService8  Public InterfaceCalservice {9 Ten     //methods applied to the Server service endpoint interface (SEI)-summation method One @WebMethod A      Public DoubleAddDoubleIDoublej); -      -     //methods applied to the Server service endpoint interface (SEI)-the method of finding the difference the @WebMethod -      Public DoubleSubDoubleIDoublej); -      -     //methods applied to the Server service endpoint interface (SEI)-the method of quadrature + @WebMethod -      Public DoubleMulDoubleIDoublej); +      A     //methods applied to the Server service endpoint interface (SEI)-the method of seeking quotient at @WebMethod -      Public DoubleDivDoubleIDoublej); -      -}

Step Two: Write the implementation class Calserviceimpl of the interface.

1  PackageCom.fx.inf.impl;2 3 ImportJavax.jws.WebMethod;4 ImportJavax.jws.WebService;5 6 ImportCom.fx.inf.CalService;7 8 //Endpointinterface indicates that the class must implement all methods of this interface, servicename represents the service name of the Web service9@WebService (endpointinterface= "Com.fx.inf.CalService", servicename= "Calservice")Ten  Public classCalserviceimplImplementsCalservice { One  A @Override - @WebMethod -      Public DoubleAddDoubleIDoublej) { the         //TODO auto-generated Method Stub -         returni +J; -     } -  + @Override - @WebMethod +      Public DoubleSubDoubleIDoublej) { A         //TODO auto-generated Method Stub at         returnIJ; -     } -  - @Override - @WebMethod -      Public DoubleMulDoubleIDoublej) { in         //TODO auto-generated Method Stub -         returnIJ; to     } +  - @Override the @WebMethod *      Public DoubleDivDoubleIDoublej) { $         //TODO auto-generated Method StubPanax Notoginseng         if(J! = 0 ) { -             returnIJ; the}Else{ +             return0; A         } the     } +  -}

Step three: Write the test method and publish the service.

1  Packagecom.fx.test;2 3 ImportJavax.xml.ws.Endpoint;4 5 ImportCom.fx.inf.CalService;6 ImportCom.fx.inf.impl.CalServiceImpl;7 8  Public classCalservicetest {9 Ten      Public Static voidMain (string[] args) { OneSYSTEM.OUT.PRINTLN ("--->web Service Start"); A          -Calservice cal =NewCalserviceimpl (); -String address = "Http://localhost:8888/cal"; the         //Publish this service - endpoint.publish (address, Cal); -     } -      +}

Run the test and publish successfully:

　　

Fourth step: Open a browser, enter http://localhost:8888/cal? WSDL, get some information, this is the WSDL file:

　　

Borrow the CXF tool (there are instructions in the bin directory of CXF to automatically convert the WSDL file to a JavaBean file) and compile the WSDL into a JavaBean file:

　　

Fifth step: Copy the resulting files to a new Java project:

　　

To write a test class:

1  Packagecom.fx.test;2 3 ImportCom.fx.inf.CalService;4 5  Public classCaltest {6 7      Public Static voidMain (string[] args) {8         9Com.fx.inf.impl.CalService cal =NewCom.fx.inf.impl.CalService ();Ten          OneCalservice Calser =Cal.getcalserviceimplport (); A          -SYSTEM.OUT.PRINTLN ("--->add:" + calser.add (1, 2)); -SYSTEM.OUT.PRINTLN ("--->sub:" + calser.sub (1, 2)); theSYSTEM.OUT.PRINTLN ("--->mul:" + Calser.mul (1, 2)); -SYSTEM.OUT.PRINTLN ("--->div:" + calser.div (1, 2)); -          -     } +      -}

Run and get results:

　　

PS: Here must note that the previous release of the service of the Java project do not stop, otherwise this will be an error:
