我的第一个WebService例子

1. 编写客户端BookService.java

package com.bookstore.service;
     import com.bookstore.model.Book;
     public class BookService {
   public String getBook(){
      System.out.println("调用成功");
          return "HelloWorld！";
   }
}

2.修改web.xml文件

<?xml version="1.0" encoding="ISO-8859-1"?>

<!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>

    <listener>
        <listener-class>org.apache.axis.transport.http.AxisHTTPSessionListener</listener-class>
    </listener>

<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>
    <servlet-name>AdminServlet</servlet-name>
    <display-name>Axis Admin Servlet</display-name>
    <servlet-class>
        org.apache.axis.transport.http.AdminServlet
    </servlet-class>
    <load-on-startup>100</load-on-startup>
</servlet>

<servlet>
    <servlet-name>SOAPMonitorService</servlet-name>
    <display-name>SOAPMonitorService</display-name>
    <servlet-class>
        org.apache.axis.monitor.soAPMonitorService
    </servlet-class>
    <init-param>
      <param-name>SOAPMonitorPort</param-name>
      <param-value>5001</param-value>
    </init-param>
    <load-on-startup>100</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/servlet/AxisServlet</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>*.jws</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>SOAPMonitorService</servlet-name>
    <url-pattern>/SOAPMonitor</url-pattern>
</servlet-mapping>




    <session-config>
        
        <session-timeout>5</session-timeout>
    </session-config>

    
<mime-mapping>
    <extension>wsdl</extension>
     <mime-type>text/xml</mime-type>
</mime-mapping>

<mime-mapping>
    <extension>xsd</extension>
    <mime-type>text/xml</mime-type>
</mime-mapping>

<welcome-file-list id="WelcomeFileList">
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.jws</welcome-file>
</welcome-file-list>

</web-app>

3.在WEB-INF下创建server-config.wsdd

<?xml version="1.0" encoding="UTF-8"?>
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<handler type="java:org.apache.axis.handlers.http.URLMapper" name="URLMapper"/>
   <service name="bookService" provider="java:RPC">
        <parameter name="className" value="com.bookstore.service.BookService"/>
        <parameter name="allowedMethods" value="*"/>
    </service>
<transport name="http">
<requestFlow>
    <handler type="URLMapper"/>
</requestFlow>
</transport>
</deployment>

4.编写客户端test.java

package com.bookstore.service;

import java.net.MalformedURLException;
import java.rmi.remoteexception;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class test {

   /**
   * @param args
   * @throws ServiceException
   * @throws MalformedURLException
   * @throws remoteexception
   */
   public static void main(String[] args) throws ServiceException,MalformedURLException,remoteexception {
       // Todo Auto-generated method stub
          String endpoint = "http://localhost:8080/hh/services/bookService";
            Service service = new Service();                // 创建一个Service实例，注意是必须的！
            Call call = (Call) service.createCall();   // 创建Call实例，也是必须的！
            call.setTargetEndpointAddress(new java.net.URL(endpoint));// 为Call设置服务的位置
            call.setoperationName("getBook");              // 注意方法名与JavaBeanWS.java中一样！！
            String res = (String) call.invoke(new Object[] {});       // 返回String，传入参数
            System.out.println(res);

   }

}

5.测试

a.在浏览器中输入http://localhost:8080/hh/servlet/AxisServlet 后访问结果为

点击wsdl可看到wsdl文件

输入参数后的访问结果为（http://localhost:8080/hh/services/bookService?method=getBook）

console端的输出为：

总结： 1.WebService并不难，按照步骤配置就可以。

2.本实验传递的是String，但是当传递Book对象类型的时候就会出错，具体解决方案等找到原因会及时奉上！
