WebService之WSDL和SOAP实例(基于JAVA)

2015-01-31 17:41 417 查看
SOAPJavaWebServiceServletWeb
开发环境：jdk1.6 + Tomcat 6.0.18 + MyEclipse6.0


首先是使用WSDL协议实现:这里使用XFire

XFire一个免费、开源的SOAP框架，它构建了POJO和SOA之间的桥梁，主要特性就是支持将POJO通过非常简单的方式发布成Web服务，其原理是以接口反射机制自动取得远程方法的

WSDL是一个用来描述Web服务和说明如何与Web服务通信的XML语言

准备：开发之前请先到官网(http://xfire.codehaus.org/Download)下载xfire-distribution-1.2.6.zip并解压缩

(1)、新建一个Web项目(服务端)，名称为XFireWebService，其目的是为了测试WebService服务端

为工程添加XFire支持的类库，把xfire-1.2.6里lib所有jar和xfire-all-1.2.6.jar拷贝到工程lib里

(2)、把XFire加载到系统中来，增加web.xml的配置信息

Java代码







<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/servlet/XFireServlet/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet>
<servlet-name>XFireServlet</servlet-name>
<servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>

<url-pattern>/services/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>


(3)、创建Web服务接口，声明该Web服务对外暴露的接口

Java代码







package com.test.ws; import java.util.List; /** * <p>Title: IHelloService</p> * <p>Description: 定义接口</p> */ public interface IHelloService { public String getTestString(String str); public ExceedVO getTestObject(EnterVO vo); public List getTestList(List list); }
package com.test.ws;
import java.util.List;
/**
* <p>Title: IHelloService</p>
* <p>Description: 定义接口</p>
*/
public interface IHelloService {
public String getTestString(String str);
public ExceedVO getTestObject(EnterVO vo);
public List getTestList(List list);
}


(4)、创建Web服务实现类，为Web服务接口提供实现

Java代码







package com.test.ws;
import java.util.ArrayList;
import java.util.List;
/**
* <p>Title: HelloServiceImpl</p>
* <p>Description: 接口实现</p>
*/
public class HelloServiceImpl implements IHelloService {

@Override
public String getTestString(String str) {
return "Hello" + str;
}

@Override
public ExceedVO getTestObject(EnterVO vo) {
ExceedVO revo = new ExceedVO();
revo.setDescStr("名称："+vo.getName()+"年龄："+vo.getAge());
return revo;
}

@Override
public List getTestList(List list) {
List<EnterVO> users = new ArrayList<EnterVO>();
for(int i=0; i<9; i++){
EnterVO user = new EnterVO("姓名"+i, i);
users.add(user);
}
return users;
}
}

package com.test.ws;
import java.util.ArrayList;
import java.util.List;
/**
* <p>Title: HelloServiceImpl</p>
* <p>Description: 接口实现</p>
*/
public class HelloServiceImpl implements IHelloService {

@Override
public String getTestString(String str) {
return "Hello" + str;
}

@Override
public ExceedVO getTestObject(EnterVO vo) {
ExceedVO revo = new ExceedVO();
revo.setDescStr("名称："+vo.getName()+"年龄："+vo.getAge());
return revo;
}

@Override
public List getTestList(List list) {
List<EnterVO> users = new ArrayList<EnterVO>();
for(int i=0; i<9; i++){
EnterVO user = new EnterVO("姓名"+i, i);
users.add(user);
}
return users;
}
}


(5)、这两个类是具体的业务实现类，对业务方法的具体实现放在里面

Java代码







package com.test.ws; import java.io.Serializable; /** * <p>Title: EnterVO</p> * <p>Description: 入参对象</p> */ public class EnterVO implements Serializable { private static final long serialVersionUID = 1L; private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public EnterVO(String name, int age) { this.name = name; this.age = age; } public EnterVO() { } } package com.test.ws; import java.io.Serializable; /** * <p>Title: ExceedVO</p> * <p>Description: 出参对象</p> */ public class ExceedVO implements Serializable { private static final long serialVersionUID = 1L; private String descStr; public String getDescStr() { return descStr; } public void setDescStr(String descStr) { this.descStr = descStr; } }
package com.test.ws;
import java.io.Serializable;
/**
* <p>Title: EnterVO</p>
* <p>Description: 入参对象</p>
*/
public class EnterVO implements Serializable {
private static final long serialVersionUID = 1L;
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public EnterVO(String name, int age) {
this.name = name;
this.age = age;
}
public EnterVO() { }
}

package com.test.ws;
import java.io.Serializable;
/**
* <p>Title: ExceedVO</p>
* <p>Description: 出参对象</p>
*/
public class ExceedVO implements Serializable {
private static final long serialVersionUID = 1L;
private String descStr;
public String getDescStr() {
return descStr;
}
public void setDescStr(String descStr) {
this.descStr = descStr;
}
}


(6)、在src目录下新建一个META-INF文件夹里包含xfire/service.xml该文件是XFire框架的服务发布文件

Java代码







<?xml version="1.0" encoding="UTF-8"?> <!-- 服务发布文件 --> <beans xmlns="http://xfire.codehaus.org/config/1.0"> <service> <!-- service标签和它所包含的xml内容为发布成Web服务的POJO提供完整的描述 --> <name>HelloService</name> <!-- Web服务被发布时所采用的唯一名称 --> <namespace>http://test/HelloService</namespace> <!-- Web服务发布时所使用的命名空间 --> <serviceClass>com.test.ws.IHelloService</serviceClass> <!-- Web服务接口类的全名 --> <implementationClass>com.test.ws.HelloServiceImpl</implementationClass> <!-- Web服务实现类的全名 --> <!-- 不需要接口时，把业务写在serviceClass标签中 --> </service> </beans>
<?xml version="1.0" encoding="UTF-8"?>
<!-- 服务发布文件 -->
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service> <!-- service标签和它所包含的xml内容为发布成Web服务的POJO提供完整的描述 -->
<name>HelloService</name> <!-- Web服务被发布时所采用的唯一名称 -->
<namespace>http://test/HelloService</namespace> <!-- Web服务发布时所使用的命名空间 -->
<serviceClass>com.test.ws.IHelloService</serviceClass> <!-- Web服务接口类的全名 -->
<implementationClass>com.test.ws.HelloServiceImpl</implementationClass> <!-- Web服务实现类的全名 -->
<!-- 不需要接口时，把业务写在serviceClass标签中 -->
</service>
</beans>


(7)、注意：当用到List等集合类型时，需要定义Mapping关系

必须与接口同名后缀.aegis.xml，而且要与接口同一位置

Java代码







<mappings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xfire.codehaus.org/schemas/1.0/mapping.xsd"> <!-- XFire可以支持基本类型，但针对集合类型时需要特殊配置 --> <mapping> <method name="getTestList"> <!-- 需要配置的方法名 --> <!-- index="0"代表方法的参数的序号0即第一个参数，componentType属性代表集合参数内包含的类型 --> <parameter index="0" componentType="java.lang.String" /> <!-- 配置返回类型，componentType属性代表返回的集合中所包含的类 --> <return-type componentType="com.test.ws.EnterVO" /> </method> </mapping> </mappings>
<mappings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xfire.codehaus.org/schemas/1.0/mapping.xsd">
<!-- XFire可以支持基本类型，但针对集合类型时需要特殊配置 -->
<mapping>
<method name="getTestList"> <!-- 需要配置的方法名 -->
<!-- index="0"代表方法的参数的序号0即第一个参数，componentType属性代表集合参数内包含的类型 -->
<parameter index="0" componentType="java.lang.String" />
<!-- 配置返回类型，componentType属性代表返回的集合中所包含的类 -->
<return-type componentType="com.test.ws.EnterVO" />
</method>
</mapping>
</mappings>


web.xml和service.xml都可以通过IDE自动生成，也可以手写

(8)、到这步webService服务端就基本完成

部署项目，启动Tomcat，测试一下wsdl，访问http://localhost:8080/XFireWebService/services/HelloService?wsdl

如果能正确显示wsdl文件，说明刚才的部署成功了！！！

(9)、再建一个Web项目(客户端)，名称为XFireWebClient，其目的是用来调用一个webService服务

将XFire的库文件拷贝到Web项目的WEB-INF\lib目录下，同时需要将服务器端发布的服务打包发布给客户端，发布给客户端的代码只需要打包接口和参数类即可，实现类不必打包到客户端

这里发布的jar包名称为IHelloService.jar，里面包含IHelloService、EnterVO、ExceedVO这三个类

(10)、在这个Web项目里面新建一个Servlet作为测试的Servlet，名称为ClientTestServlet.java

在web.xml里面配置好这个Servlet后，就可以在Servlet里面写webService调用的代码了

Java代码







package com.test.ws; import java.io.IOException; import java.net.MalformedURLException; import java.util.ArrayList; import java.util.List; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.codehaus.xfire.XFire; import org.codehaus.xfire.XFireFactory; import org.codehaus.xfire.client.XFireProxyFactory; import org.codehaus.xfire.service.Service; import org.codehaus.xfire.service.binding.ObjectServiceFactory; /** * <p>Title: ClientTestServlet</p> * <p>Description: 测试Servlet</p> */ public class ClientTestServlet extends HttpServlet { private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("UTF-8"); Service serviceModel = new ObjectServiceFactory().create(IHelloService.class); XFire xfire = XFireFactory.newInstance().getXFire(); XFireProxyFactory factory = new XFireProxyFactory(xfire); String serviceUrl = "http://localhost:8080/XFireWebService/services/HelloService"; IHelloService client = null; try { client = (IHelloService) factory.create(serviceModel, serviceUrl); } catch (MalformedURLException e) { e.printStackTrace(); } String str = client.getTestString("Beijing"); request.setAttribute("str", str); EnterVO enterVO = new EnterVO(); enterVO.setName("Yaodi"); enterVO.setAge(26); ExceedVO vo = client.getTestObject(enterVO); request.setAttribute("vo", vo); List<String> al = new ArrayList<String>(); al.add("111"); al.add("222"); al.add("333"); List list = client.getTestList(al); request.setAttribute("list", list); request.getRequestDispatcher("/result.jsp").forward(request, response); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request,response); } }
package com.test.ws;
import java.io.IOException;
import java.net.MalformedURLException;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.codehaus.xfire.XFire;
import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
/**
* <p>Title: ClientTestServlet</p>
* <p>Description: 测试Servlet</p>
*/
public class ClientTestServlet extends HttpServlet {

private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

request.setCharacterEncoding("UTF-8");
Service serviceModel = new ObjectServiceFactory().create(IHelloService.class);
XFire xfire = XFireFactory.newInstance().getXFire();
XFireProxyFactory factory = new XFireProxyFactory(xfire);
String serviceUrl = "http://localhost:8080/XFireWebService/services/HelloService";
IHelloService client = null;
try {
client = (IHelloService) factory.create(serviceModel, serviceUrl);
} catch (MalformedURLException e) {
e.printStackTrace();
}

String str = client.getTestString("Beijing");
request.setAttribute("str", str);

EnterVO enterVO = new EnterVO();
enterVO.setName("Yaodi");
enterVO.setAge(26);
ExceedVO vo = client.getTestObject(enterVO);
request.setAttribute("vo", vo);

List<String> al = new ArrayList<String>();
al.add("111");
al.add("222");
al.add("333");
List list = client.getTestList(al);
request.setAttribute("list", list);

request.getRequestDispatcher("/result.jsp").forward(request, response);
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}

}


客户端的web.xml如下所示：

Java代码







<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>ClientTestServlet</servlet-name> <servlet-class>com.test.ws.ClientTestServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>ClientTestServlet</servlet-name> <url-pattern>/ClientTest.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>ClientTest.do</welcome-file> </welcome-file-list> </web-app>
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet>

<url-pattern>/ClientTest.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>ClientTest.do</welcome-file>
</welcome-file-list>
</web-app>


(11)、注意：XFireWebService项目里的IHelloService.aegis.xml文件，也要放到XFireWebClient项目中来，位置与ClientTestServlet.java同级

(12)、Servlet返回的结果页面：result.jsp

Java代码







<%@ page language="java" pageEncoding="UTF-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ page isELIgnored="false"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>测试客户端</title> </head> <body> 测试客户端！！！<br> String：${str} <br> Object：${vo.descStr} <br> List：<br> <c:forEach items="${list}" var="list"> ${list.name} --- ${list.age} <br> </c:forEach> </body> </html>
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page isELIgnored="false"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>测试客户端</title>
</head>
<body>
测试客户端！！！<br>
String：${str} <br>
Object：${vo.descStr} <br>
List：<br>
<c:forEach items="${list}" var="list">
${list.name} --- ${list.age} <br>
</c:forEach>
</body>
</html>


(13)、同样将这个Web项目发布，同时启动XFireWebService和XFireWebClient这两个应用，然后在地址栏里面输入http://localhost:8080/XFireWebClient/

此时会调用客户端的Servlet，然后调用其doGet方法，如果正常的话，可以看到页面输出结果了(*^__^*)

问题：在项目中使用XFire发布服务，在本地测试一切正常，但是传到服务器上，发现List的第一个元素是没有内容的，后面的元素内容显示正常，

通过调试服务端没有问题，是往客户端之间传输时丢失的，目前的解决办法比较2，是在List前面加了一条垃圾数据，故意把List的第一个元素挤下来。

希望有人能帮我解答！！！谢谢



其次是使用SOAP协议实现:有时需要其它语言做服务端，java做客户端，就要用到SOAP获取WebService了

SOAP简单对象访问协议是一种轻量的、简单的、基于 XML 的协议，它被设计成在WEB上交换结构化的和固化的信息

这里演示的例子服务端和客户端都是java

首先从网站http://xml.apache.org/soap/index.html下载soap，解压得到soap.war

把soap.war放到Tomcat\webapps\目录下

(1)、新建一个Web项目(服务端)名为SoapService

(2)、编写服务端代码HelloWorldService.java

Java代码







package HelloWorld;
/**
* <p>Title: HelloWorldService</p>
* <p>Description: 服务端</p>
*/
public class HelloWorldService {
public String getMessage(){
return "Hello World!!!";
}
public String getMessage(String str1, String str2) {
return "Hello World! " + str1 + "&" + str2;
}
}

package HelloWorld;
/**
* <p>Title: HelloWorldService</p>
* <p>Description: 服务端</p>
*/
public class HelloWorldService {
public String getMessage(){
return "Hello World!!!";
}
public String getMessage(String str1, String str2) {
return "Hello World! " + str1 + "&" + str2;
}
}


编写完成后，将HelloWorldService发布jar到Tomcat\lib\目录中

(3)、SOAP服务的发布

启动Tomcat自动将soap.war解压，访问http://localhost:8080/soap/admin/，会出现soap的管理页面

注意：这里会出现错误是因为在Tomcat\lib\目录下缺少sun的mail.jar

进入Deploy，填写如下信息：

ID: hello

Scope: Request

Methods getMessage

Provider Type: Java

Java Provider Provider Class: HelloWorld.HelloWorldService

Java Provider Static: NO

确认发布，可以点List查看已发布服务！

(4)、再建一个Web项目(客户端)名为SoapClient

为工程增加4个jar文件：xerces、soap、activation、mail

(5)、在这个Web项目里面新建一个Servlet作为测试的Servlet，名称为HelloWorldClientServlet.java

在web.xml里面配置好这个Servlet后，就可以在Servlet里面写webService调用的代码了

Java代码







package HelloWorld;

public class HelloWorldClientServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
String endPoint = "http://localhost:8080/soap/servlet/rpcrouter"; //url是固定的，带参数绑定

Parameter p2 = new Parameter("name2", String.class, "张飞", null);
params.addElement(p1);
params.addElement(p2);
call.setParams(params);
URL url = new URL(endPoint); //SOAP服务的网址，开始发送RPC请求，并返回服务端的应答
Response resp = null;
try { //检查应答报中文是否有错（有错就打印出错信息，没错就打印返回信息）
resp = call.invoke(url, "");
} catch (SOAPException e) {
e.printStackTrace();
}
if(resp.generatedFault()){
Fault fault = resp.getFault();
System.out.println("The Following Error Occured:");
System.out.println("Fault Code=" + fault.getFaultCode());
System.out.println("Fault String=" + fault.getFaultString());
} else {
Parameter result = resp.getReturnValue();
System.out.println(result.getValue());
request.setAttribute("str", result.getValue());
}
request.getRequestDispatcher("/result.jsp").forward(request, response);

}
request.getRequestDispatcher("/result.jsp").forward(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}
}


客户端的web.xml如下所示：

Java代码

(6)、Servlet返回的结果页面：result.jsp

Java代码

(7)、运行客户端，测试是否通过

同时启动SoapService和SoapClient这两个应用，访问http://localhost:8080/SoapClient/

应该可以看到返回的内容，则证明配置和测试成功，以后就可以发布自己的SOAP服务了！
