Java calls WebService instances

WebService is a service-specific architecture that provides services through a standard web protocol to ensure that application services from different platforms can interoperate. At present, the most popular implementation is the use of. NET and JAVA Two language technology, and the two implementation languages can interoperate with each other;

The

Below is mainly about language ; >w Ebservice definition and invocation, through java language development xfire , cxf jws way to achieve has its own characteristics, because I use Cxf way more skilled, and, CFX and s pring seamlessly combined, so the following highlights the cfx Span style= "font-family: the song Body;" The implementation of the method .

Since the Webservice implementation is divided into two development modes: Server and client, the next part introduces WebService Server Development, client development and instance testing.

1. Environment preparation

JDK1.6 and above, the required jar files are:commons-logging-1.1.1.jar, Cxf-2.4.3.jar, Neethi-3.0.1.jar, Spring-aop-3.0.5.release.jar, Spring-asm-3.0.5.release.jar, Spring-beans-3.0.5.release.jar, Spring-context-3.0.5.release.jar, Spring-context-support-3.0.5.release.jar, Spring-core-3.0.5.release.jar, Spring-expression-3.0.5.release.jar, Spring-web-3.0.5.release.jar, Wsdl4j-1.6.2.jar, Xmlschema-core-2.0.1.jar.

1. Server-Side development

Custom interface Classes

Package cn.test.ws.service;

import Javax.jws.WebParam;

import Javax.jws.WebService;

@WebService

Public Interface Greetingservice {

Public String Welcome (@WebParam (name= "username") string username);

Public int getnum (@WebParam (name= "number") int number);

}

Defining an interface implementation class

Package Cn.test.ws.service.impl;

import Cn.test.ws.service.GreetingService;

Public class Greetingserviceimpl implements Greetingservice {

@Override

Public String welcome (string username) {

System. out. println (" Server-side method:greeting ()");

return "Hell0" +username+ ", welcome you to call JAVA under the WebService service !";

}

@Override

Public int getnum (int number) {

System. out. println (" Server-side method:getnum ()");

return number;

}

}

Spring.xml Configuration

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="Http://www.springframework.org/schema/beans"

xmlns:xsi="Http://www.w3.org/2001/XMLSchema-instance"

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

<import resource="Classpath:meta-inf/cxf/cxf.xml" />

<import resource="Classpath:meta-inf/cxf/cxf-servlet.xml" />

<jaxws:server id="Greetingservice"

serviceclass="Cn.test.ws.service.GreetingService"

address="/greetingservice">

<jaxws:serviceBean>

</jaxws:serviceBean>

<jaxws:features>

<bean class="org.apache.cxf.feature.LoggingFeature" />

</jaxws:features>

</jaxws:server>

</beans>

2. Client Development

Public Static void Main (string[] args) {

jaxwsdynamicclientfactory DCF = jaxwsdynamicclientfactory. newinstance ();

String Wsurl = "http://127.0.0.1:8080/WS/GreetingService?wsdl";

String method = "Welcome";

String method2 = "Getnum";

Try {

Client client = dcf.createclient (Wsurl);

Object[] Objects =client.invoke (method, "TEST");

Object[] Numbers =client.invoke (method2,6);

System. out. println (Objects[0].tostring ());

System. out. println (Numbers[0]);

} catch (Exception e) {

E.printstacktrace ();

}

}

3. Example Test

The webservice test can be tested using the client main method described above, as well as by testing in a browser, and by means of a dedicated WebService test Tool .

Enter Http://IP: port / project name/greetingservice?wsdl in the browser to see the published service-side information, and to display the information returned by the server by entering the parameters, such as: Http://IP: Port / project name/greetingservice/welcome?username=test.
