WebService 简单应用

一.编写服务器端

1.在myeclipes中新建一个webservive项目mywebservice

2.配置web.xml

   
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <servlet>
    <servlet-name>XFireServlet</servlet-name>
    <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3.新建接口类Helloworldservice

	package com.web.service;

	public interface Helloworldservice {
		public String sayHellow(String str);
	}

4.新建实现类Helloworldservice

	package com.web.impl;

	import com.web.service.Helloworldservice;

	public class Helloworldimpl implements Helloworldservice {

		public String sayHellow(String str) {
			return "您好,"+str+"!";
		}

	}

5.配置services.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<!--服务名称-->
<name>hellow</name>
<namespace>gjy</namespace>
<!--服务接口-->
<serviceClass>com.gjy.inter.Helloworldservice</serviceClass>
<!--服务实现类-->
<implementationClass>com.gjy.impl.Helloworldimpl</implementationClass>
</service>
</beans>

至此服务器端编写完毕

在tomcat中部署mywebservice,启动tomcat,在浏览器中输入http://localhost:8088/mywebservice/services/hellow?wsdl,回车,出现以下内容,证明服务器端编写成功

  <?xml version="1.0" encoding="UTF-8" ?> 
- <wsdl:definitions targetNamespace="gjy" xmlns:soapenc12="http://www.w3.org/2003/05/soap-encoding" xmlns:tns="gjy" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap11="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc11="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
- <wsdl:types>
- <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="gjy">
- <xsd:element name="sayHellow">
- <xsd:complexType>
- <xsd:sequence>
  <xsd:element maxOccurs="1" minOccurs="1" name="in0" nillable="true" type="xsd:string" /> 
  </xsd:sequence>
  </xsd:complexType>
  </xsd:element>
- <xsd:element name="sayHellowResponse">

  <xsd:element maxOccurs="1" minOccurs="1" name="out" nillable="true" type="xsd:string" /> 
  </xsd:sequence>
  </xsd:complexType>

  </xsd:schema>
  </wsdl:types>
- <wsdl:message name="sayHellowRequest">
  <wsdl:part name="parameters" element="tns:sayHellow" /> 
  </wsdl:message>
- <wsdl:message name="sayHellowResponse">
  <wsdl:part name="parameters" element="tns:sayHellowResponse" /> 
  </wsdl:message>
- <wsdl:portType name="hellowPortType">
- <wsdl:operation name="sayHellow">
  <wsdl:input name="sayHellowRequest" message="tns:sayHellowRequest" /> 
  <wsdl:output name="sayHellowResponse" message="tns:sayHellowResponse" /> 
  </wsdl:operation>
  </wsdl:portType>
- <wsdl:binding name="hellowHttpBinding" type="tns:hellowPortType">

  <wsdlsoap:operation soapAction="" /> 
- <wsdl:input name="sayHellowRequest">
  <wsdlsoap:body use="literal" /> 
  </wsdl:input>
- <wsdl:output name="sayHellowResponse">
  <wsdlsoap:body use="literal" /> 
  </wsdl:output>
  </wsdl:operation>
  </wsdl:binding>
- <wsdl:service name="hellow">
- <wsdl:port name="hellowHttpPort" binding="tns:hellowHttpBinding">
  <wsdlsoap:address location="http://localhost:8088/mywebservice/services/hellow" /> 
  </wsdl:port>
  </wsdl:service>
  </wsdl:definitions>

二.客户端编写

1.新建一个普通的java工程WebwerviceClient,引入XFire的jar包


2.编写客户端代码

package com.web.client;

import java.net.MalformedURLException;
import java.net.URL;

import org.codehaus.xfire.client.Client;

public class HelloworldClient {
	public static void main(String args[]){
		 try {
			   Client client=new Client(new URL("http://localhost:8088/mywebservice/services/hellow?wsdl"));
			   Object[] result=client.invoke("sayHellow", new Object[]{"龚先生"});
			   System.out.println(result[0]);
			  } catch (MalformedURLException e) {
			   e.printStackTrace();
			  } catch (Exception e) {
			   e.printStackTrace();
			}

	}
}

启动服务端,运行客户端,出现结果: 您好,龚先生!

至此一个简单的webservice应用开发完毕.
