一、环境搭建
下载axis2-1.6.2-war.zip/axis2-1.6.2-bin.zip等。
参考axis2-1.6.2-war\README.txt以及axis2-1.6.2-war\axis2\WEB-INF\services\version-1.6.2\META-INF\services.xml的写法，可以通过编写webservice类并打包成jar的形式放在Tomcat容器的axis2 webapp下的services目录进行发布。
测试：把axis2目录拷贝到%TOMCAT_HOME%/webapps目录下面，启动tomcat，并访问http://localhost:8080/axis2，正常。
二、编写webservice server端
1 bean
package com.test.entity;
public class Student {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "Student [id=" + id + ", name=" + name + "]";
}
}
2 webservice class
package com.test;
import com.test.entity.Student;
public class HelloWorld {
public String sayHello() {
return "saying hellooooooooooooo----2----";
}
public Student query() {
Student s = new Student();
s.setId("1");
s.setName("wsc123");
return s;
}
public Integer addTowNumbers(int a, int b) {
return a+b;
}
}
3 services.xml
<service name="HelloWorld">
<description>
This service is to get the running Axis version
</description>
<parameter name="ServiceClass">com.test.HelloWorld</parameter>
<operation name="sayHello">
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="query">
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="addTowNumbers">
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
</service>
<!--
<service name="HelloWorld" scope="application">
<description>
POJO: HelloWorld Service
</description>
<messageReceivers>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</messageReceivers>
<parameter name="ServiceClass">com.test.HelloWorld</parameter>
</service>
-->
4 build.xml
<project name="helloworldservice" basedir="." default="deploy">
<property name="src.dir" value="src">
</property>
<property name="build.dir" value="${basedir}/build">
</property>
<path id="build.classpath">
</path>
<target name="init">
<delete dir="${build.dir}">
</delete>
<mkdir dir="${build.dir}" />
<mkdir dir="${build.dir}/classes" />
<mkdir dir="${build.dir}/jar" />
</target>
<target name="compile" depends="init">
<javac srcdir="${src.dir}" destdir="${build.dir}\classes">
<classpath refid="build.classpath">
</classpath>
</javac>
</target>
<target name="makejar" depends="compile">
<jar destfile="${build.dir}\jar\${ant.project.name}.jar">
<fileset dir="${build.dir}/classes">
<include name="**/*.class"/>
</fileset>
<metainf dir="${basedir}">
<include name="services.xml"/>
</metainf>
</jar>
</target>
<target name="deploy" depends="makejar">
<copy file="${build.dir}/jar/${ant.project.name}.jar" todir="D:\wsc\software\apache-tomcat-6.0.41\webapps\axis2\WEB-INF\services"></copy>
</target>
</project>
5 readme.txt
通过POJO的方式发布一个WebService到tomcat容器中。
这里需要注意的是：
Ant打成的Jar的格式，META-INF目录下必须包括services.xml，
以及services.xml的写法，可以认为每个方法就是一对operation标签。。
三、编写RPC client端
1 需要引用axis2-1.6.2-war\axis2\WEB-INF\lib\*.jar
2 bean/entity
package com.test.entity;
public class Student {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "Student [id=" + id + ", name=" + name + "]";
}
}
3 rpc client类
package sample.addressbook.rpcclient;
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
import com.test.entity.Student;
public class HelloWorldRPCClient {
public static void main(String[] args1) throws AxisFault {
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
EndpointReference targetEPR = new EndpointReference("http://127.0.0.1:8080/axis2/services/HelloWorld");
options.setTo(targetEPR);
// QName of the target method
QName qName = new QName("http://test.com", "sayHello");
// Constructing the arguments array for the method invocation
Object[] opArgs = new Object[] {};
Class[] returnTypes = new Class[] { String.class };
// Invoking the method
Object[] response = serviceClient.invokeBlocking(qName, opArgs, returnTypes);
System.out.println(response[0]);
//如何返回一个对象？？
//
qName = new QName("http://test.com", "query");
opArgs = new Object[]{};
returnTypes = new Class[] {Student.class};
response = serviceClient.invokeBlocking(qName, opArgs, returnTypes);
System.out.println(response[0]);
//如何传递参数到web service方法中？
qName = new QName("http://test.com", "addTowNumbers");
//opArgs = new Object[]{Integer.valueOf(3), Integer.valueOf(4)};
opArgs = new Object[]{33, 44};
returnTypes = new Class[]{Integer.class};
response = serviceClient.invokeBlocking(qName, opArgs, returnTypes);
System.out.println(response[0]);
}
}
4 运行结果
log4j:WARN No appenders could be found for logger (org.apache.axis2.context.AbstractContext).
log4j:WARN Please initialize the log4j system properly.
saying hellooooooooooooo----2----
Student [id=1, name=wsc123]

参考Axis2的samples目录下的pojo示例
重点是sample.addressbook.rpcclient.HelloWorldRPCClient这个类，用于访问自己发布的HelloWorld这个WebService。
四、问题
客户端可以用多种形式，如adb访问？
Axis2支持多种协议，http应该是最常用的。还有？
