使用Axis2开发Web Service简单演示实例

 

首先提供其网页

 

http://axis.apache.org/axis2/java/core/

 

下载：http://labs.renren.com/apache-mirror//axis/axis2/java/core/1.5.3/axis2-1.5.3-bin.zip

 

 

然后我使用的是Eclipse开发。在Preferences-> Web Services-> Axis2 Preferences设置目录信息，其他默认。

 

如果你手工写，还是比较麻烦的。可参考其网站文档。

 

开发容器 Tomcat6

 

Web Service在Web中使用，新建一个myServices工程。

假设该文件提供了服务入口：

/** * */package com.service;/** * @author Administrator * */public class FacadeService {public static String facade(String request) {String response = "resp: " ;response += request;return response;}} 

假设该文件提供web services入口

 

/** * */package com.services;import com.service.FacadeService;/** * @author Administrator * */public class InvokeService {public String invoke(String req) {String response = "invoke: " ;response += FacadeService.facade(req);return response;}} 

然后，使用上面的POJO发布为Web Services。如图：

 

然后默认即可。

 

发布成功后，可以在浏览器查看http://localhost:8080/myServices/services/InvokeService?wsdl

上述地址，可以通过http://localhost:8080/myServices/axis2-web/index.jsp查看服务获得。

http://localhost:8080/myServices/services/listServices

 

下面的是该wsdl文件：

<?xml version="1.0" encoding="UTF-8" ?> - <wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:ns1="http://org.apache.axis2/xsd" xmlns:ns="http://services.com" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" targetNamespace="http://services.com"> <wsdl:documentation>Please Type your service description here</wsdl:documentation> - <wsdl:types>- <xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://services.com">- <xs:element name="invoke">- <xs:complexType>- <xs:sequence> <xs:element minOccurs="0" name="req" nillable="true" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element>- <xs:element name="invokeResponse">- <xs:complexType>- <xs:sequence> <xs:element minOccurs="0" name="return" nillable="true" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> </wsdl:types>- <wsdl:message name="invokeRequest"> <wsdl:part name="parameters" element="ns:invoke" /> </wsdl:message>- <wsdl:message name="invokeResponse"> <wsdl:part name="parameters" element="ns:invokeResponse" /> </wsdl:message>- <wsdl:portType name="InvokeServicePortType">- <wsdl:operation name="invoke"> <wsdl:input message="ns:invokeRequest" wsaw:Action="urn:invoke" /> <wsdl:output message="ns:invokeResponse" wsaw:Action="urn:invokeResponse" /> </wsdl:operation> </wsdl:portType>- <wsdl:binding name="InvokeServiceSoap11Binding" type="ns:InvokeServicePortType"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" mce_style="document" /> - <wsdl:operation name="invoke"> <soap:operation soapAction="urn:invoke" style="document" mce_style="document" /> - <wsdl:input> <soap:body use="literal" /> </wsdl:input>- <wsdl:output> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding>- <wsdl:binding name="InvokeServiceSoap12Binding" type="ns:InvokeServicePortType"> <soap12:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" mce_style="document" /> - <wsdl:operation name="invoke"> <soap12:operation soapAction="urn:invoke" style="document" mce_style="document" /> - <wsdl:input> <soap12:body use="literal" /> </wsdl:input>- <wsdl:output> <soap12:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding>- <wsdl:binding name="InvokeServiceHttpBinding" type="ns:InvokeServicePortType"> <http:binding verb="POST" /> - <wsdl:operation name="invoke"> <http:operation location="InvokeService/invoke" /> - <wsdl:input> <mime:content type="text/xml" part="invoke" /> </wsdl:input>- <wsdl:output> <mime:content type="text/xml" part="invoke" /> </wsdl:output> </wsdl:operation> </wsdl:binding>- <wsdl:service name="InvokeService">- <wsdl:port name="InvokeServiceHttpSoap11Endpoint" binding="ns:InvokeServiceSoap11Binding"> <soap:address location="http://localhost:8080/myServices/services/InvokeService.InvokeServiceHttpSoap11Endpoint/" /> </wsdl:port>- <wsdl:port name="InvokeServiceHttpSoap12Endpoint" binding="ns:InvokeServiceSoap12Binding"> <soap12:address location="http://localhost:8080/myServices/services/InvokeService.InvokeServiceHttpSoap12Endpoint/" /> </wsdl:port>- <wsdl:port name="InvokeServiceHttpEndpoint" binding="ns:InvokeServiceHttpBinding"> <http:address location="http://localhost:8080/myServices/services/InvokeService.InvokeServiceHttpEndpoint/" /> </wsdl:port> </wsdl:service> </wsdl:definitions> 

 

此时，服务器端编写完成。

 

其他描述可以查看该工程其他文件内容。可以不管。

 

客户端编写：

 

新建一个Java工程。

新建Web Service Client。

选择刚才的wsdl描述。进行创建。

http://localhost:8080/myServices/services/InvokeService?wsdl

 

Eclipse可以自动生成客户端。

 

上面的包含测试的情况。TestClient.jsp是该页面。

 

可以使用客户端代码调用了。

需要客户端调用参考，选择Junit测试。参考即可。

Java代码调用

 返回

invoke: resp: 大家好
