webservice 入门事例 源代码

?? ? 最近准备考试：将webservice 充充电，本想配置一遍，在网上资料，资源虽多，没有几个能成功的，还没有几个有原代码的，可能是自己理解能力有限，摸索了一段时间，终于调通了webservice ！

? ? 在此为想学习webservice同仁们提供一个入门例子

?

?1、新建一个web project，如下面的例子为Storm

?2、在工程中目录如下图所示

?

Storm.
│? .classpath
│? .project
│? index.html
│? tree.txt
│ ?
├─.settings
│????? com.spket.js.prefs
│????? org.eclipse.core.resources.prefs
│???? ?
├─src
│? └─com
│????? │? TestDWR.java
│????? │? TestWebService.java
│????? │ ?
│????? └─service
│????????????? HelloWorld.java
│???????????? ?
└─WEB-INF
??? │? server-config.wsdd
??? │? web.xml
??? │ ?
??? ├─attachments
??? ├─classes
??? │? └─com
??? │????? │? TestDWR.class
??? │????? │? TestWebService.class
??? │????? │ ?
??? │????? └─service
??? │????????????? HelloWorld.class
??? │???????????? ?
??? └─lib
??????????? axis-ant.jar
??????????? axis.jar
??????????? commons-discovery-0.2.jar
??????????? commons-logging-1.0.4.jar
??????????? jaxrpc.jar
??????????? log4j-1.2.8.jar
??????????? saaj.jar
??????????? wsdl4j-1.5.1.jar

3、编写java类

public class HelloWorld {

	private String name = "qingfeng";
	
	public String getName(){
		return name;
	}
	public String hiHello(String name)
	{
		return "Hi:" + name;
	}
}

4、修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app  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" version="2.4">

    <servlet>
        <servlet-name>AxisServlet</servlet-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>
    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
</web-app>

?5、修改 server-config.wsdd文件，与web.xml同一级目录，内容如下，在别面拷贝一个，修改自己类及方法

<?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">  

<globalConfiguration>
  <parameter name="sendMultiRefs" value="true"/>
  <parameter name="disablePrettyXML" value="true"/>
  <parameter name="dotNetSoapEncFix" value="true"/>
  <parameter name="enableNamespacePrefixOptimization" value="false"/>
  <parameter name="sendXMLDeclaration" value="true"/>
  <parameter name="sendXsiTypes" value="true"/>
  <parameter name="attachments.implementation" value="org.apache.axis.attachments.AttachmentsImpl"/>
</globalConfiguration>

  <handler type="java:org.apache.axis.handlers.http.URLMapper" name="URLMapper"/>  
  
   <service name="hello" provider="java:RPC"> 
      <parameter name="className" value="com.service.HelloWorld" /> 
      <parameter name="allowedMethods" value="*" /> 
   </service> 
  
   <service name="test" provider="java:RPC"> 
      <parameter name="className" value="com.TestDWR" /> 
      <parameter name="allowedMethods" value="*" /> 
   </service>  
   
  <transport name="http">  
     <requestFlow>  
        <handler type="URLMapper"/>  
     </requestFlow>  
  </transport>  
</deployment>

6、将相关的jar加上，如上述目录所示，将工程布置到tomcat中，

7、访问发布的路径，如我本地为：http://localhost:8080/Storm/services

8、若在IE中，看到如下所示，就表明成功了

?

And now... Some Services

hello (wsdl)

• helloName
• getName

test? (wsdl)

• getAge

9、下面我们再写一个测试类，提供外界访问，在工程目录中com.TestWebService类，代码如下所示

package com;

import javax.xml.rpc.ServiceException;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class TestWebService {

	public static void test2() {
		String url = "http://localhost:8080/Storm/services/hello";
		Service service = new Service();
		Call call;
		String name = "东东和范范";
		try {
			call = (Call) service.createCall();
			call.setTargetEndpointAddress(new java.net.URL(url));
			call.setOperationName("helloName");
			String res = (String) call.invoke(new Object[] { name });
			System.out.println(res);
		} catch (ServiceException e) {
			e.printStackTrace();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		test2();
	}

}

?10、在控制台输出【hello:东东和范范】表明成功。

?11、附上整个项目源代码
