Spring's WebService development

Because the project was developed using spring, the author chose Apache CXF for WebService development, because the Apache CXF provides a convenient spring integration method that can be annotated,  Spring-tagged configuration to expose Web services and Consumer Web services. 

1.  first go to http://cxf.apache.org/download.html to download the latest version (currently 2.4.1)   

2.  Import the appropriate package into the project, presumably the following package:

Commons-logging-1.1.1.jar

Geronimo-activation_1.1_spec-1.0-m1.jar (or Sun ' s activation jar)

Geronimo-annotation_1.0_spec-1.1.jar (JSR 250)

Geronimo-javamail_1.4_spec-1.7.1.jar (or Sun ' s javamail jar)

Geronimo-servlet_3.0_spec-1.0.jar (or Sun ' s servlet jar)

Geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181)

Jaxb-api-2.1.jar

Jaxb-impl-2.1.13.jar

Jaxws-api-2.1.jar

Neethi-3.0.0.jar

Saaj-api-1.3.jar

Saaj-impl-1.3.jar

Stax-api-1.0.1.jar

Stax2-api-3.1.1.jar

Wsdl4j-1.6.2.jar

Woodstox-core-asl-4.0.8.jar

Xmlschema-core-2.0.jar

Xml-resolver-1.2.jar

Cxf-2.4.0.jar

Spring 's bag will not be said. 

3.  Create a new interface

@WebService

Public Interface helloworldservice {

Public string Getnewname (string userName);

}

Use @WebService identity to let cxf know to use this interface to create WSDL  

4.  Create a new implementation class

@WebService(endpointinterface="Org.app.demo.spring.service.HelloWorldService")

Public class Helloworldserviceimpl implements helloworldservice {

Public string Getnewname (String userName) {

return "Hello spring!" + userName;

}

}

5.  Modify the appropriate configuration file

Add the following code to the applicationcontext.xml

<jaxws:endpoint

id="HelloWorld"

implementor="Org.app.demo.spring.service.impl.HelloWorldServiceImpl"

address="/helloworld" /> 

Or

<bean id= " helloworldservice" class= " org.app.demo.spring.service.impl.HelloWorldServiceImpl"/ >   

<jaxws:endpoint

id="HelloWorld"

implementor="#helloWorldService"

address="/helloworld" /> 

Note: TheXML header file needs to be added accordingly

Xmlns:jaxws= "Http://cxf.apache.org/jaxws

Http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd

Add the following code to Web. xml

<servlet>

<servlet-name>cxfservlet</servlet-name>

<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>

<load-on-startup>2</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>cxfservlet</servlet-name>

<url-pattern>/*</url-pattern>

</servlet-mapping>

6.  start Tomcat and open the http://localhost:8080/myapp/HelloWorld?wsdl to see  

7.  Client invocation is also very convenient, the following code:

URL wsdlurl = new url ("http://192.168.0.114:8080/myapp/HelloWorld?wsdl");

QName service_name = new QName ("http://impl.service.spring.demo.app.org/"," Helloworldserviceimplservice ");

Service service = service. Create (Wsdlurl, service_name);

HelloWorldService Hello = Service.getport (helloworldservice. Class);

System.  out . println (Hello.getnewname ("WebService call "));    

Then after executing the code, the  Hello spring! is printed out WebService called . 

1. Address of the server with IP address WebService. 

The corresponding interface must be copied to the client project.
