axis2 webService开发指南（2）

1  Axis2的简单WebService示例

1.1 新建一个web工程，创建一个类Greeting，用于当作webservice服务

代码如下:

package amyservices;

import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.List;

import Com.WebService.Model.Person;

public class Greeting {
    public String getGreeting(String name){
        return "你好：" + name;
    }
    
    public int getPrice()
    {
        return new java.util.Random().nextInt(1000);
    }
    
    public List<Person> GetPersonList()
    {
        List<Person> list = new ArrayList<Person>();
        Person model = new Person();
        model.setKeyID("1214324234234234324");
        model.setName("張三");
        Calendar birth = Calendar.getInstance();
        birth.set(1990, 11, 22);
        model.setBirth(birth);
        list.add(model);
        model = new Person();
        model.setKeyID("1214324234234234324");
        model.setName("李四");
        birth = Calendar.getInstance();
        birth.set(1990, 11, 22);
        model.setBirth(birth);
        System.out.println(birth.toString());
        list.add(model);
        for(Person item : list)
        {
            System.out.println(item.getName());
        }
        
        return list;
    }
    
    public String PrintNow()
    {
        Calendar cale = Calendar.getInstance();
        Date tasktime=cale.getTime();  
        SimpleDateFormat df=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
        System.out.println(df.format(tasktime));
        return  df.format(tasktime);
    }
}

.classpath文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">
        <attributes>
            <attribute name="owner.project.facets" value="java"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="con" path="com.genuitec.runtime.library/com.genuitec.generic_7.0">
        <attributes>
            <attribute name="owner.project.facets" value="jst.web"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.web.container"/>
    <classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.module.container"/>
    <classpathentry kind="con" path="com.genuitec.runtime.library/com.genuitec.jstl_1.2.2">
        <attributes>
            <attribute name="org.eclipse.jst.component.dependency" value="WEB-INF/lib"/>
            <attribute name="owner.project.facets" value="jst.web.jstl"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="output" path="WebRoot/WEB-INF/classes"/>
</classpath>

1.2 点击File-->New-->other，选择Axis2 Service Archiver

配置Class File Location，配置路径到工程的WEB-INF\classess目录下，同时将下图的复选框勾选去掉，继续根据向导完成创建。

创建成功，在axis2的工程目录下，多了我们刚配置好的文件

输入网址http://localhost:8080/axis2/services/listServices，会发现增加了我们刚创建的服务。

2 创建客户端

2.1 创建一个java项目

2.2 新建一个WsClient测试类

代码如下：

package com.amy.client;

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;

public class WsClient {
    private RPCServiceClient serviceClient;  
    private Options options;
    private EndpointReference targetERP;
    
    public WsClient(String endpoint) throws AxisFault{
        this.serviceClient = new RPCServiceClient();
        this.options = this.serviceClient.getOptions();
        this.targetERP = new EndpointReference(endpoint);
        this.options.setTo(this.targetERP);
    }
    
    public Object[] invokeOp(String targetNamespace, String opName,Object[] opArgs, Class<?>[]opReturnType) throws AxisFault, ClassNotFoundException{
        QName opQName = new QName(targetNamespace, opName);
        return this.serviceClient.invokeBlocking(opQName, opArgs, opReturnType);
    }
    
    public static void main(String args[])
    {
        final String endpointReference = "http://localhost:8080/axis2/services/WebServiceTest1";
        final String targetNamesPace = "http://amyservices";
        try {
            WsClient client = new WsClient(endpointReference);
            String opName = "GetPersonList";
            Object[] opArgs = new Object[]{};
            Class<?>[] opReturnType = new Class[]{Person.class};
            Object[] response = client.invokeOp(targetNamesPace, opName, opArgs, opReturnType);
            if (response != null && response.length > 0)
            {
                System.out.println(response.length);
                for(Object obj : response)
                {
                    Person model = (Person)obj;
                    System.out.println(model.getName());
                }
            }
             
        } catch (AxisFault e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
         
    }
}

2.3 要引用的jar包有

　　.classpath文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7"/>
    <classpathentry kind="lib" path="lib/axiom-impl-1.2.13.jar"/>
    <classpathentry kind="lib" path="lib/axis2-adb-1.6.2.jar"/>
    <classpathentry kind="lib" path="lib/axis2-kernel-1.6.2.jar" sourcepath="C:/Users/zhujinrong/.m2/repository/org/apache/axis2/axis2-kernel/1.6.2/axis2-kernel-1.6.2-sources.jar"/>

    <classpathentry kind="lib" path="lib/activation-1.1.jar"/>
    <classpathentry kind="lib" path="lib/axis2-adb-codegen-1.6.2.jar"/>
    <classpathentry kind="lib" path="lib/axis2-java2wsdl-1.6.2.jar"/>
    <classpathentry kind="lib" path="lib/mail-1.4.jar"/>
