使用Axis2发布webservice并使用客户端调用.
目的:使用Axis2发布webservice并使用客户端调用.
1.到http://ws.apache.org/axis2/1_4_1/installationguide.html上面下载 axis2-1.4.1-bin.zip ,里面有JKD,Tomcat版本的要求.
2.下载到的axis2-1.4.1-bin.zip解压到axis2-1.4.1-bin目录.Copy lib目录到已有工程目录.
3.web.xml增加servlet配置.
<servlet> <description> </description> <display-name>Apache-Axis Servlet</display-name> <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>
4.启动已有问工程,测试是否报错.若有 javax.xml.包找不到的错误,建议使用 jdk1.6.或者找到jar包加载进去.
5.增加一个Class.
package example; public class HelloWorldService { public HelloWorldService() { } public String hello(String userName) { return "Hello axis2 service!" + userName; } public String helloNoParam() { return "测试!"; } }
6.手工配置 services.xml.(目录结构为:WEB-INF/services/HW/META-INF/services.xml,其中HW可以命名为其他.文件夹不存在的就新增.)
<serviceGroup>
<service name="HelloWorldService">
<description>Hello World Service</description>
<parameter name="ServiceClass" locked="false">example.HelloWorldService</parameter>
<operation name="hello" mep="http://www.w3.org/2004/08/wsdl/in-out">
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="helloNoParam">
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
</service>
</serviceGroup>
7.重新打包并在Tomcat中运行.在IE中输入http://localhost:8080/testProject/services/HelloWorldService?wsdl,可以看到发布的服务,xml.有的浏览器中只会显示服务名,如Google Chrome.
8.使用Java调用刚发布的接口.
首先,使用个通用类(在某论坛里面看到的一个兄弟的通用方法.)
package example;
import java.util.Iterator;
import javax.xml.namespace.QName;
import org.apache.axiom.om.OMElement;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
public class Axis2CommonClient {
public Axis2CommonClient() {
}
/**
*
* @param srvcUrl
* 访问的url
* @param namespace
* 命名空间
* @param operateName
* 你想调用的方法
* @param param
* 要传入的参数。
* @return
* @throws Exception
*/
public Object excute(String srvcUrl, String namespace, String operateName,
Object param[]) throws Exception {
QName qname = new QName(namespace, operateName);
RPCServiceClient client = new RPCServiceClient();
Options options = new Options();
options.setTo(new EndpointReference(srvcUrl));
options.setAction("urn:" + operateName);
client.setOptions(options);
OMElement element = client.invokeBlocking(qname, param);
if (element != null && !"".equals(element)) {
Iterator<?> values = element.getChildrenWithName(new QName(
namespace, "return"));
while (values.hasNext()) {
OMElement omElement = (OMElement) values.next();
return omElement.getText();
}
} else {
return element;
}
return "-1";
}
}
9.客户端代码.
package example;
public class TestClient {
public static void main(String[] args) throws Exception {
String url = "http://localhost:8080/testProject/services/HelloWorldService";
String namespace = "http://example";//此处的命名空间 example 应与发布的服务中的命名空间保持一致.
String operateName = "hello";
String[] param = new String[] { "xx" };
Axis2CommonClient axClient = new Axis2CommonClient();
Object obj = axClient.excute(url, namespace, operateName, param);
System.out.println(obj);
operateName = "helloNoParam";
obj = axClient.excute(url, namespace, operateName, param);
System.out.println(obj);
}
}
10.Run AS Java Application,打印出
Hello axis2 service!xx
测试!
