大家好,又见面了,我是全栈君,今天给大家准备了Idea注册码。
Web Service简单入门示例
我们一般实现Web Service的方法有非常多种。当中我主要使用了CXF Apache插件和Axis 2两种。
Web Service是应用服务商为了解决每一个问题而提供的在线服务方案,其主要採用了SOAP(Simple Object Access Protocol)协议,传输数据格式使用XML格式来描写叙述。因此也具有跨平台的特性。
web广泛用到的技术:
- TCP/IP:通用 网络协议。被各种设备使用
- HTML( 标准通用标记语言下的一个应用):通用用户界面,能够使用HTML标签显示数据
- Java:写一次能够在不论什么系统执行的通用 编程语言,由于java具有跨平台特性
- XML( 标准通用标记语言下的一个子集):通用数据表达语言,在web上传送结构化数据的easy方法
他们的特点是其开放性。跨平台性,开放性正是Web services的基础。
以下是使用CXF Apache的插件实现Web Service的一个简单入门实例
1========新建一个服务接口
package com.clark;
import javax.jws.WebParam; import javax.jws.WebService;
@WebService public interface IHelloWorld { public String sayHello(@WebParam(name=”name”)String name); public int plus(int a,int b); } 2========服务接口实现类
package com.clark.impl;
import com.clark.IHelloWorld;
public class HelloWorldImpl implements IHelloWorld {
@Override public String sayHello(String name) { return “Hello Wolrd ,”+name; }
@Override public int plus(int a, int b) { return a+b; }
}
3============服务端
package com.clark.service;
import javax.xml.ws.Endpoint;
import com.clark.impl.HelloWorldImpl;
public class WebServiceApp { public static void main(String[] args) { System.out.println(“web service start”); HelloWorldImpl implementor = new HelloWorldImpl(); String address = “http://localhost:8080/IHelloWorld”; Endpoint.publish(address, implementor); System.out.println(“web service started”); } }
4============client(以下主要是针对Java普通程序的) package com.clark.client;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.clark.IHelloWorld;
public class HelloWorldClient { public static void main(String[] args) { JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean(); svr.setServiceClass(IHelloWorld.class); svr.setAddress(“http://localhost:8080/CXFWebService/service/IHelloWorld”); IHelloWorld hw = (IHelloWorld) svr.create(); String name = hw.sayHello(” CXF Apache implements Web Service”); int result = hw.plus(2, 3); System.out.println(name); System.out.println(result); } }
4==============client(针对Spring中集成Web Service的Web开发) package com.clark.web;
import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.clark.IHelloWorld;
public class HelloWorldClient { public static void main(String[] args) { System.out.println(“Web Service start……….”); ApplicationContext context = new ClassPathXmlApplicationContext(“applicationContext.xml”); IHelloWorld helloWorld = (IHelloWorld)context.getBean(“client”); String name = helloWorld.sayHello(“1111111111”); int result = helloWorld.plus(3, 4); System.out.println(name+” “+result); System.out.println(“Web Service end……….”); } }
5============Spring 的 applicationContext.xml配置 <?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”>
<jaxws:endpoint id=”helloWorld” implementor=”com.clark.impl.HelloWorldImpl” address=”/IHelloWorld” /> <bean id=”client” class=”com.clark.IHelloWorld” factory-bean=”clientFactory” factory-method=”create”/> <bean id=”clientFactory” class=”org.apache.cxf.jaxws.JaxWsProxyFactoryBean”> <property name=”serviceClass” value=”com.clark.IHelloWorld”/> <property name=”address”
value=”http://localhost:8080/CXFWebService/service/IHelloWorld”/> </bean> </beans>
6=============Spring中集成Web Service服务(CXF Servlet的配置),web.xml <?
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” 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>CXFWebService</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <!– <param-value>classpath:applicationContext.xml</param-value> –> <param-value>WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>CXFServlet</servlet-name> <display-name>CXFServlet</display-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>/service/*</url-pattern> </servlet-mapping> </web-app>
7=============启动服务,地址栏输入 http://localhost:8080/CXFWebService/service/IHelloWorld?
wsdl可以看到对应的SOAP协议在规格OK
