javaeewebservice_JavaEE之WebService(示例代码)

1.WebService

a.定义&＃xff1a;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&＃xff1a; XML&＃43;XSD,SOAP&＃xff0c;WSDL

c.SOAP协议 &＃61; HTTP协议 &＃43; 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&＃xff1a;

a.在xml中配置

org.springframework.web.context.ContextLoaderListener

CXFServlet

org.apache.cxf.transport.servlet.CXFServlet

2

CXFServlet

/server/*

b.建spring-webservice.xml

c.建接口

&＃64;WebServicepublic interfaceMyWebService {int add(&＃64;WebParam(name &＃61; "firstA") int a, &＃64;WebParam(name &＃61; "firstB") intb);int minus(&＃64;WebParam(name &＃61; "secondA") int a, &＃64;WebParam(name &＃61; "secondB") intb);

}

d.建实现类

&＃64;WebService(endpointInterface &＃61; "com.wode.server.MyWebService")public class MyWebServiceImpl implementsMyWebService {

&＃64;Overridepublic int add(int a, intb) {//TODO Auto-generated method stub

System.out.println(a&＃43;b);return a&＃43;b;

}

&＃64;Overridepublic int minus(int a, intb) {//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 &＃61; newJaxWsProxyFactoryBean();

factoryBean.setServiceClass(MyWebService.class);

factoryBean.setAddress("http://127.0.0.1:8080/myService/server/HelloService");

MyWebService service&＃61;(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&＃61;newMyWebServiceImplService();

MyWebService myWebService&＃61;service.getMyWebServiceImplPort();

System.out.println(myWebService.add(10, 100)&＃43;"client");
