Axis2测试webservice server以及client

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>

4 build.xml

</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]
77

5 readme.txt

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？
