1.WebService
a.定义：WebService是一种跨编程语言和跨操作系统平台的远程调用技术
b.三大技术： XML+XSD,SOAP，WSDL
c.SOAP协议 = HTTP协议 + XML数据格式
d.WSDL:基于XML的描述语言（相当于字典、菜单）
2.服务端：
a.在xml中配置
<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>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/server/*</url-pattern>
</servlet-mapping>
b.建spring-webservice.xml
<?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://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"
default-lazy-init="true">
<bean id="webserviceServer" class="com.wode.server.impl.MyWebServiceImpl" />
<jaxws:endpoint id="myService" implementor="#webserviceServer"
address="/HelloService">
</jaxws:endpoint>
</beans>
c.建接口
@WebService
public interface MyWebService { int add(@WebParam(name = "firstA") int a, @WebParam(name = "firstB") int b); int minus(@WebParam(name = "secondA") int a, @WebParam(name = "secondB") int b); }
d.建实现类
@WebService(endpointInterface = "com.wode.server.MyWebService")
public class MyWebServiceImpl implements MyWebService { @Override
public int add(int a, int b) {
// TODO Auto-generated method stub
System.out.println(a+b);
return a+b;
} @Override
public int minus(int a, int b) {
// TODO Auto-generated method stub
System.out.println(a-b);
return a-b;
} }
e.测试（需先运行tomcat服务器tomcat:run）
JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
factoryBean.setServiceClass(MyWebService.class);
factoryBean.setAddress("http://127.0.0.1:8080/myService/server/HelloService");
MyWebService service=(MyWebService) factoryBean.create();
System.out.println(service.add(1, 3));
f.访问http://127.0.0.1:8080/myService/server/HelloService?wsdl确认是否正常
g.下载apache-cxf-3.1.11并配置环境变量
h.在控制台输入
wsdl2java -encoding utf-8 -d E:\EclipseWorkspace\myService http://127.0.0.1:8080/myService/server/HelloService?wsdl
i.将项目下com文件夹复制到客户端项目中
3.客户端
a.使用
MyWebServiceImplService service=new MyWebServiceImplService();
MyWebService myWebService=service.getMyWebServiceImplPort();
System.out.println(myWebService.add(10, 100)+"client");
