WebService基础学习笔记 - 2.WebService之AXIS定制发布
?
?
发布WSDD
?????? 1只有class,包含包的结构；
????????????? 实现步骤：
???????????????????? 1编写带有包结构的java代码（普通：方法的编写）
???????????????????? 2将该程序进行编译 –class;
???????????????????? 3将编译后的结构；
???????????????????? 4使用命令在axis服务平台上注册服务（声明服务的方法）；
????????????????????
AxisWEB-INF
???????????????????? 1编写一个当前的项目配置文件server-config.wsdd;
??????????????????????????? 1编写一个*.wsdd文件，描述某一个web服务；
??????????????????????????? <deployment name=”test” xmlns=http://xml.apache.org/axis/wsdd
??????????????????????????????????????????????????????? Xmlns:java=http://xml.apache.org/axis/wsdd/providers/java>
?????????????????? ??????????????????????????? <service name=”urn:cominfo” provider=”java:RPC”>
??????????????????????????????????????????????????????? <parametername=”className” value=”指明需要发布的类的绝对位置” />
??????????????????????????????????????????????????????? <parametername=”className” value=”方法名(*)”/>
?????????????????????????????????????????????? <service>
???????????????????????????????????? </deployment>
?
2 在Axisweb-inf下面执行命令：
?
java org.apache.axis.client.AdminClient *.wsdd : axis.jar中类 –CLASSPATH
?
?
?????? ????????????? 3 将编译后的结果(包含包的层次)拷贝到AxisWEB-INFclasses下；
????????????? ?????? 4 使用命令在axis服务平台上注册服务（声明服务的方法）
?
?????? 5 文件的结构
?????? AXIS
????????????? WEB-INF
???????????????????? ----server-config.wsdd
???????????????????? classes
??????????????????????????? ----包结构的java服务类
?
?????? 6 修改server-config.wsdd
?
?????? 7 取消服务：
????????????? 1编写取消的*wsdd
???????????????????? <undeploymentname=”test” xmlns=http://xml.apache.org/axis/wsdd/
???????????????????? ??? <service name=”要取消的服务名” />
</undeployment>
??????
????????????? 2执行命令
???????????????????? Javaorg.apache.axis.client.AdminClient 取消.wsdd;
?
?
?????? 8. Web Service Object的生存的范围
?????? ?????? <parametername=”scope” value=”request/session/application” />
????????????? request:Axis为每一个SOAP的请求产生服务对象 ----针对于请求；
????????????? session:Axis为每一个调用webService的客户端产生服务对象 ---- 针对会话；
????????????? application：在服务器的内存中直接new一个服务对象；
?
?
?
?
?
以下是练习：
?
服务端编写：
?
| package com.webservice.wsdd; public class HelloWSDD { ? ??? //定制提供web服务的方法 ??? private int requestCount = 0; ??? public String hello(String name){ ?????? requestCount++; ?????? System.out.println("调用的次数"+requestCount); ?????? return "欢迎您：" + name; ??? } ??? ??? public Float add(Float a,Float b){ ?????? return a+b; ??? } ??? ??? public static void main(String[] args) { ?????? new HelloWSDD(); ??? } } |
?
?
编译服务端代码：
?????? 将服务端的类，编译成class文件，然后连报名一起复制到AxisWEB-INFclasses目录下；
?
?
编写server-config.wsdd文件：
?
?????? 全部内容如下：
| <?xml version="1.0" encoding="UTF-8"?> <deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"> ???? <globalConfiguration>? ???????? <parameter name="adminPassword" value="admin"/>? ???????? <parameter name="attachments.implementation" value="org.apache.axis.attachments.AttachmentsImpl"/> ? ???????? <parameter name="sendXsiTypes" value="true"/>? ???????? <parameter name="sendMultiRefs" value="true"/>? ???????? <parameter name="sendXMLDeclaration" value="true"/>? ???????? <parameter name="axis.sendMinimizedElements" value="true"/>? ???? ????<requestFlow>?? ???????????? <handler type="java:org.apache.axis.handlers.JWSHandler">??? ???????????????? <parameter name="scope" value="session"/>?? ???????????? </handler>?? ???????????? <handler type="java:org.apache.axis.handlers.JWSHandler"> ??? ???????????????? <parameter name="scope" value="request"/>??? ???????????????? <parameter name="extension" value=".jwr"/>?? ???????????? </handler>? ???????? </requestFlow> ???? </globalConfiguration> ???? <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> ???? <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> ???? <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/>?? ? ? ???? <service name="HelloWSDD" provider="java:RPC"> ?????????? <parameter name="className" value="com.webservice.wsdd.HelloWSDD"/>?? ?????????? <parameter name="allowedMethods" value="*"/> ??? </service> ? ? ???? <transport name="http">? ???????? <requestFlow>?? ??????????? ?<handler type="URLMapper"/>?? ???????????? <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/>? ???????? </requestFlow> ???? </transport> ???? <transport name="local">? ???????? <responseFlow>?? ???????????? <handler type="LocalResponder"/>? ???????? </responseFlow> ???? </transport> </deployment> |
?
?
?
?
客户端调用编写：
?
| package com.client; ? import java.rmi.RemoteException; import javax.xml.namespace.QName; import javax.xml.rpc.ServiceException; import org.apache.axis.client.Call; import org.apache.axis.client.Service; ? public class TestClient { ??? public static void main(String[] args) throws ServiceException,RemoteException { ?????? String url = "http://localhost:8080/axis/services/HelloWSDD"; ?????? /*区别于JWS方式的指定 hptt://localhost:8080/axis/services/HelloWSDD.jws */ ?????? Service service = new Service(); ?????? Call call = (Call)service.createCall(); ?????? call.setTargetEndpointAddress(url); ?????? call.setOperationName(new QName(url,"add")); //解析wsdl文件 ?????? Float returnValue = (Float) call.invoke(new Object[]{ new Float(3.2), new Float(2.8)}); ?????? System.out.println(returnValue); ??? } } |
