Axis2 WebService(配置、发布、调用)

准备工作

1、下载:axis2-1.5.4-bin.zip,axis2-1.5.4-war.zip 下载地址:http://axis.apache.org/axis2/java/core/
2、环境变量设置
AXIS2_HOME E:\research\axis2-1.5.4-bin\axis2-1.5.4
JAVA_HOME C:\Program Files\Java\jdk1.6.0_21
3、axis2-1.5.4-war.zip解压,将压缩包内的axis2.war部署到%TOMCAT-HOME%/webapps下,启动tomcat,访问http://localhost:8085/axis2/看是否正常。

点击Service会进入Service列表页面,当前只有一个Version服务。http://localhost:8085/axis2/services/Version?wsdl
4、下载 axis2-eclipse-codegen-plugin-1.5.4.zip,axis2-eclipse-service-plugin-1.5.4.zip  解压后将plugins 复制到 %ECLIPSE_HOME%\plugins。
http://www.apache.org/dyn/mirrors/mirrors.cgi/axis/axis2/java/core/1.5.4/axis2-eclipse-codegen-plugin-1.5.4.zip
http://www.apache.org/dyn/mirrors/mirrors.cgi/axis/axis2/java/core/1.5.4/axis2-eclipse-service-plugin-1.5.4.zip

安装完插件后,IDE中选择new->other会看到下面界面

如果安装Axis2插件之后,在eclipse中没有出现界面,就换一个eclipse版本
在版本比较新的eclipse中,安装Axis插件,是把jar复制到%ECLIPSE_HOME%\dropins目录下,而不是plugins目录

AXIS2发布Web Services
一、工程文件

1、新建 Axis2Service1 java工程。
2、新建 \Axis2Service1\src\ws\TestWs.java

package ws;
public class TestWs {
public String showName(String name) {return name; }
public String getName() {return "Axis2Service Sample"; }
}

 二、arr部署方式

1、手动打包
新建\Axis2Service1\deploy文件夹 ,将\Axis2Service1\bin下的class文件复制过来。
新建\Axis2Service1\deploy\META-INF\services.xml文件

<service name="AxisService">
<description>AxisService</description>
<parameter name="ServiceClass">ws.TestWs</parameter>
<operation name="showName">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="getName">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
</operation>
</service>

 生成aar包 \Axis2Service1\deploy>jar cvf AxisService.aar . (注意带.号)

2、插件打包
IDE中选择New->other->Axis2 Service Archiver,点击Next;
Class File Location:选择Axis2Service1\bin目录,点击Next;
勾选Skip WSDL,点击Next;
Service Archiver 选择jar位置,如果没有jar包就直接点击Next;
勾选Generate the service xml automatically 自动生成XML file文件,点击Next
service name,输入:AxisService,然后在class name 中填写要发布的类(全路径),点击load。勾选 Search declared methods only。点击next

output File location,输入:D:\ ; output File Name,输入artiver文件的名称 AxisService。点击finish。
提示 Service Archvie generated successfully! 注册表明,生成成功。
3、发布AxisService
AxisService.aar复制到%TOMCAT-HOME%/webapps/axis2/WEB-INF/services下。(不打aar包,\Axis2Service1\deploy下面复制过去也是可以)

打开http://localhost:8085/axis2/services/listServices 看到

 

三、独立部署

1、新建java web project工程。
2、文件复制
%TOMCAT-HOME%\webapps\axis2\WEB-INF\lib 复制到 \Axis2Service2\WebRoot\WEB-INF\lib 下,并加入工程引用。
%TOMCAT-HOME%\webapps\axis2\WEB-INF\conf 复制到 \Axis2Service2\WebRoot\WEB-INF\conf
%TOMCAT-HOME%\webapps\axis2\WEB-INF\modules 复制到 \Axis2Service2\WebRoot\WEB-INF\modules
3、web.xml 代码如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="wmf" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>AxisServlet</servlet-name>
<servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>AxisServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
</web-app>

 2、新建 \Axis2Service2\src\ws\TestWs.java

package ws;
public class TestWs {
public String showName(String name) {return name; }
public String getName() {return "Axis2Service Sample"; }
}

 3、新建\Axis2Service2\WebRoot\WEB-INF\services目录。

4、新建一个AxisService服务
AxisService\META-INF\services.xml

<service name="AxisService">
<description>AxisService</description>
<parameter name="ServiceClass">ws.TestWs</parameter>
<operation name="showName">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="getName">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
</operation>
</service>

 启动tomcat后,访问http://localhost:8085/Axis2Service2/services/AxisService?wsdl看是否正常。

Axis2客户端调用:

以上面的例子为例,调用代码如下:

package ws;

import java.rmi.RemoteException;

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;


/** 
 * @Description: TODO
 * @author luickystar2008
 * @date 2013-10-14 下午8:01:17 
 */

public class TestWs {
	/**
	 * 
	 */
	public static void main(String[] args) {
		try {
			RPCServiceClient rpcServiceClient = new RPCServiceClient();
			Options options = rpcServiceClient.getOptions();
			EndpointReference targetEPR = new EndpointReference("http://localhost:8080/Axis2Service2/services/AxisService");
			options.setTo(targetEPR);
			
			// 1.有参数,有返回值的调用
			String callback = (String) rpcServiceClient.invokeBlocking(new QName("http://ws","showName"), new Object[]{"Hello!"},new Class[]{String.class})[0];
			System.out.println(callback);
			// 2.无参数,有返回值的方法调用
			Object[] obj = rpcServiceClient.invokeBlocking(new QName("http://ws","getName"), new Object[]{},new Class[]{String.class});
			System.out.println(obj[0]);
			
			// 3.无参数,无返回值的调用
			rpcServiceClient.invokeRobust(new QName("http://ws","hello"), new Object[]{});
		} catch (AxisFault e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (RemoteException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

在调用一个无参有返回值的方法时抛出如下异常:

org.apache.axis2.AxisFault: The input stream for an incoming message is null.
 
错误原因是我的services.xml文件配置错误。
方法如下:
public String getHello(){return "Hello World";}
在services.xml中应该这样写:
<operation name="getHello">  
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>  
    </operation>  
而不应该是:
<operation name="getHello">  
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>  
    </operation>  
解决该异常主要有两点:

1、

        当方法体没有参数返回的时候,我们要采用RPCServiceClient.invokeRobust(QName, new Object[]{..});
        当有返回参数的时候采用:RPCServiceClient.invokeBlocking(QName, new Object[]{..},new Class[]{..})

 

2、services.xml配置中,

<operation name="getHello">
         <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
         <!-- 有返回值 -->
 </operation>
 <operation name="hello">
          <messageReceiver  class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
          <!-- 无返回值 -->
 </operation>

 

public String getHello(){return "hello world";}

public String getHello(String name ){return name+" Hello";}

public void hello(String a){ this.a = a;}
