CXF fast and simple implementation of WebService calls

WebService's history and related technologies

Reference: http://www.cnblogs.com/doosmile/archive/2012/06/21/2557351.html

WebService technology is now very mature, big wave after the sand, the current Java Development WebService framework mainly includes AXIS2 and CXF.

Axis2 and CXF are all Apache-owned products, but their purpose is different, resulting in webservice development methods. Two frameworks have been supported by developers. It is necessary to compare the two.

	Axis2	CXF
Goal	WebService engine	A simple SOA framework that can be used as an ESB
ws* Standard Support	Ws-policy not supported	Ws-addressing,ws-policy, WS-RM, Ws-security,ws-i Basic profile
Data binding Support	XMLBeans, JiBX, JaxMe, Jaxbri, ADB	JAXB, Aegis, XMLBeans, SDO, JiBX
Spring integration	Not supported	Support
Application integration	Difficult	Simple
Multi-lingual	Support for C + +	Not supported
Deployment	Web Apps	Embedded
Service Monitoring and management	Support	Not supported

Conclusion:

1. If you want to implement webservice in a consistent way, especially if you have cross-language requirements, you should use Axis2
2. If you need to add WebService support to existing Java programs, including Web apps, you should use CXF

Specific implementation:

<bean id= "Greetingserviceimpl" class= "com.Mycompany.webservice.server.GreetingServiceImpl"/>
<jaxws:endpoint id= "Greetingservice" implementor= "#greetingServiceImpl" address= "/greeting" />

Interface

Package com.mycompany.webservice.server;

Import Javax.jws.WebService;

@WebService
Public interface Greeting {
public string Greeting (string userName);
}

Implementation class

Package com.mycompany.webservice.server;

Import Java.util.Calendar;
Import Javax.jws.WebService;

@WebService (endpointinterface = "com.mycompany.webservice.server.Greeting")
public class Greetingserviceimpl implements greeting {

public string Greeting (string userName) {
Return "Hello" + UserName + ", CurrentTime is"
+ calendar.getinstance (). GetTime ();
}
}

Client

public class Greetingserviceclient {
public static void Main (string[] args) {
Create a WebService Client Agent factory
Jaxwsproxyfactorybean factory = new Jaxwsproxyfactorybean ();
Registering the WebService interface
Factory.setserviceclass (Greeting.class);
Set WebService Address
Factory.setaddress ("http://localhost:8080/yourprogramname/webservice/greeting");
Greeting Greetingservice = (greeting) factory.create ();
System.out.println ("Invoke WebService ...");
SYSTEM.OUT.PRINTLN ("Message context is:" +greetingservice.greeting ("Gary"));
}
}
