J2EE应用：WebService服务的实现及调用

作者：archie2010 编辑：胡铭娅 2011-07-14 13:44 来源：archie2

　　【IT168 技术】

　　eclipse下新建webapp项目

　　此WebService服务由Axis实现,样例项目所需要jar包及目录：

　　Web.xml配置

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web
Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
  <display-name>Apache-Axis</display-name>
  
  <servlet>
    <servlet-name>AxisServlet</servlet-name>
    <display-name>Apache-Axis Servlet</display-name>
    <servlet-class>
     org.apache.axis.transport.http.AxisServlet
    </servlet-class>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>
</web-app>

WebService服务：

package com.archie.service;
/**
* 服务MyService
* @author archie
*
* since 2011-7-13 下午02:34:57
*/
public class SayHelloService {
    /**
     * 输出List集中字符串
     * @return
     */
    public String SayHello2WS(String name){ return "Hello,WebService!"+"_____by"+"\t"+name;
    }
}

WebService服务的配置(server-config.xml)

　　server-config.xml(WEB-INF目录下)

<?xml version="1.0" encoding="UTF-8"?>
<deployment name="defaultClientConfig"

</service>
<service name="Version" type="" regenerateElement="false" provider="java:RPC">

</service>

<service name="SayHelloService" provider="java:RPC">
<parameter name="className" value="com.archie.service.SayHelloService"/>
<parameter name="allowedMethods" value="*" />
</service>
</deployment>

　　Tomcat6.0下发布

　　URL:http://localhost:8080/MyWebService/services/SayHelloService

　　浏览其wsdl文件

　　URL:http://localhost:8080/MyWebService/services/SayHelloService?wsdl

　　wsdl

<?xml version="1.0" encoding="UTF-8" ?>

　　该服务的调用：

package com.archie.service.test;
import javax.xml.namespace.QName;
import javax.xml.rpc.Call;
import javax.xml.rpc.ParameterMode;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
/**
* WebService接口测试
* @author archie
*
* since 2011-7-13 下午02:06:37
*/
public class TestSayHello {
public static void main(String[] args) throws Exception {
//创建一个服务对象
Service service = new Service();
//创建一个对方法的调用
Call call = service.createCall();
/**
* 设置调用的终端地址
* AnotherMethod为server-config.wsdd的Service配置名称
*/
String url = "http://localhost:8080/MyWebService/services/SayHelloService";
call.setTargetEndpointAddress(
url);
call.setReturnType(XMLType.XSD_STRING);
//设置操作名，即所调用的方法的名称
call.setOperationName(new QName("SayHello2WS"));
//添加参数（参数名，参数类型，参数传递模式）
call.addParameter("name", XMLType.XSD_STRING, ParameterMode.IN);
//调用方法
String res = (String) call.invoke(new Object[]{"archie"});
System.out.println("调用返回结果:"+res);
}
}
