webService的客户端与服务端的编写

发布时间：2020-12-16 22:54:56 所属栏目：安全 来源：网络整理
导读：步骤， 先编写服务端， 服务端编写完通过生成*.xml文件， 使用Apache cxf 生成客户端代码 写个User 实体类吧 span style="font-size:14px;"package demo;public class User {private String name;public String getName() {return name;}public void setName

步骤， 先编写服务端， 服务端编写完通过生成*.xml文件， 使用Apache cxf 生成客户端代码


写个User 实体类吧

<span style="font-size:14px;">package demo;

public class User {
	
	private String name;

	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	
}
</span></span></span>


先写服务端的接口

<span style="font-size:14px;"><span style="font-size:12px;"><span style="font-size:14px;">package demo;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
@SOAPBinding(style=Style.RPC)
@WebService
public interface HelloWorld {
	
	public String sayHi();
	
	public String sayHitoUser(User user);
	
	public String  updateUser(User user);
}</span></span></span>
在写接口的实现类 
<span style="font-size:14px;"><span style="font-size:12px;"><span style="font-size:14px;">package demo;

import javax.jws.WebService;

@WebService(endpointInterface="demo.HelloWorld",serviceName="HelloWorld")
public class HelloWorldImpl implements HelloWorld{
		
	public String sayHi() {
		return "say : HI";
	}
	public String sayHitoUser(User user) {
		return "User--------haha";
	}
	public String updateUser(User user) {
		System.out.println("Update : user");
		return "updateUser";
	}
}</span></span></span>
以上代码很简单的

下面开始贴 application配置文件

<span style="font-size:14px;"><span style="font-size:12px;"><span style="font-size:14px;"><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
			               http://www.springframework.org/schema/beans/spring-beans.xsd
			               http://cxf.apache.org/jaxws 
			               http://cxf.apache.org/schemas/jaxws.xsd">                  
            <import resource="classpath:META-INF/cxf/cxf.xml"/>
	    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
	    <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
	 
	 <!--
     <jaxws:endpoint id="helloWorld" implementor="HelloWorldImpl" address="/helloWorld"/>
         -->
    
     	<!-- 第二种发布方式：带有接口的发布 -->		
        <!-- 
            id:唯一标识
            address：访问url
            serviceClass：接口类型
         -->
        <jaxws:server id="helloWorld" address="/helloWorld"
            serviceClass="demo.HelloWorld">
            <jaxws:serviceBean>
                <!-- 提供服务的实现类 -->
                <bean class="demo.HelloWorldImpl"></bean>
            </jaxws:serviceBean>
    
            <!-- 加入消息拦截器  
            <jaxws:inInterceptors>
                <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>
            </jaxws:inInterceptors>
            <jaxws:outInterceptors>
                <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean>
            </jaxws:outInterceptors>
            -->
        </jaxws:server> 
    
</beans>

接着是web.xml
</span><pre name="code" class="html"><?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>webs</display-name>
  <welcome-file-list>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
  <context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>WEB-INF/classes/applicationContext.xml</param-value>
	</context-param>
 
	<listener>
		<listener-class>
          org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

	 <!-- 配置CXF框架的核心Servlet  -->
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
	<servlet-class>
			org.apache.cxf.transport.servlet.CXFServlet
	</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<servlet-mapping>
      <servlet-name>CXFServlet</servlet-name>
      <url-pattern>/*</url-pattern>
   </servlet-mapping>
</web-app></span></span>

以上就是一个简单WEBservice服务端的简单demo
想webservice启动起来， 通过访问http://localhost:8080/工程名/（上面我们配置的address）helloWorld/(webx.xml中的servleturl)helloWorld?wsdl
会有类似这种的文档 
<span style="font-size:14px;"><span style="font-size:12px;"><wsdl:definitions name="HelloWorldService" targetNamespace="http://demo/"><wsdl:types><xs:schema targetNamespace="http://demo/" version="1.0"><xs:complexType name="user"><xs:sequence><xs:element minOccurs="0" name="name" type="xs:string"/></xs:sequence></xs:complexType></xs:schema></wsdl:types><wsdl:message name="sayHi">
  </wsdl:message><wsdl:message name="updateUser"><wsdl:part name="arg0" type="tns:user">
    </wsdl:part></wsdl:message><wsdl:message name="sayHitoUserResponse"><wsdl:part name="return" type="xsd:string">
    </wsdl:part></wsdl:message><wsdl:message name="sayHiResponse"><wsdl:part name="return" type="xsd:string">

好的重点来了， 讲访问的页面保存为*.xml格式的文件，例如 userService.xml


下面我们通过userService.xml 使用Apache cxf 生成客户端代码

先配置环境变量 CXF_HOME = E:apache-cxf-2.6.2 （这个目录主要看你的Apache-cxf在那个盘中，我的在E盘）
PATH = %CXF_HOME%/bin
CLASS_PATH = %CXF_HONE%/lib
Apache-cxf 生成客户端代码 可以直接打开cmd 用命令 wsdl2java http://localhost:8080/工程名/(address)helloWorld/(servleturl)hellowld?wsdl
或者 wsdl2java -d e:C -client E:/userService.xml
执行完以上命令 找到生成的文件将文件放入新建工程客户端代码
下面贴出客户端的applicationContext.xml 配置信息
 
<span style="font-size:14px;"><span style="font-size:12px;"><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
			               http://www.springframework.org/schema/beans/spring-beans.xsd
			               http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
	
        <import resource="classpath:META-INF/cxf/cxf.xml"/>
	    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
	    <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
	 
     <bean id="client" class="demo.HelloWorld"  factory-bean="clientFactory" factory-method="create"/>
    		 
    <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
          <!-- 调用服务端的类  -->
?       <property name="serviceClass" value="demo.HelloWorld"/>
????????? <!-- addRess即为webservice的url? -->
       ?<property name="address" value="http://localhost:8080/helloWorld/helloWorld"/>
      </bean>
</beans>

下面贴出 客户端web.xml

<pre name="code" class="html"><?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

	</servlet>
	
	<servlet-mapping>
