SOA实现方式之一：使用Apache CXF 框架

一、服务端

1、配置xml

you simply need to provide the class name and an address

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://·") public interface GreetingService { public String greeting(String userName); }

targetNamespace是命名空间，将来会是客户端默认包结构。接口必须给接口加上@WebService ?，否则会报 Service endpoint interface does not have a @WebService annotation.

实现：必须有 endpointInterface 声明

@Service("GreetingServiceImpl") @WebService(serviceName = "hello",portName="GreetingServicePort", endpointInterface = "com.gary.test.ws.service.GreetingService", targetNamespace = "ws.test.gary.com") public class GreetingServiceImpl implements GreetingService { public String greeting(String userName) { return "Hello " + userName + ", currentTime is " + Calendar.getInstance().getTime(); } public GreetingServiceImpl() { super(); } }

serviceName，portName对应：

endpointInterface 对应：

最后生成的WSDL为：

<wsdl:definitions xmlns:xsd="http://·" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" name="hello" targetNamespace="ws.test.gary.com"> <wsdl:types> <xs:schema xmlns:xs="http://·" elementFormDefault="unqualified" targetNamespace="ws.test.gary.com" version="1.0"> <xs:element name="greeting" type="tns:greeting"/> <xs:element name="greetingResponse" type="tns:greetingResponse"/> <xs:complexType name="greeting"> <xs:sequence> <xs:element minOccurs="0" name="arg0" type="xs:string"/> </xs:sequence> </xs:complexType> <xs:complexType name="greetingResponse"> <xs:sequence> <xs:element minOccurs="0" name="return" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:schema> </wsdl:types> <wsdl:message name="greeting"> <wsdl:part element="tns:greeting" name="parameters"></wsdl:part> </wsdl:message> <wsdl:message name="greetingResponse"> <wsdl:part element="tns:greetingResponse" name="parameters"></wsdl:part> </wsdl:message> <wsdl:portType name="GreetingService"> <wsdl:operation name="greeting"> <wsdl:input message="tns:greeting" name="greeting"></wsdl:input> <wsdl:output message="tns:greetingResponse" name="greetingResponse"></wsdl:output> </wsdl:operation> </wsdl:portType> <wsdl:binding name="helloSoapBinding" type="tns:GreetingService"> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="greeting"> <soap:operation soapAction="" style="document"/> <wsdl:input name="greeting"> <soap:body use="literal"/> </wsdl:input> <wsdl:output name="greetingResponse"> <soap:body use="literal"/> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="hello"> <wsdl:port binding="tns:helloSoapBinding" name="GreetingServicePort"> <soap:address location="http://localhost:8080/CXFWS/webservice/helloworld"/> </wsdl:port> </wsdl:service> </wsdl:definitions> View Code

注意：如果不配置serviceName,portName 则默认生成：服务名：类名+Service, 接口：类名+Port

二、CXF 客户端

生成代码：tns 命名空间的倒叙。

F:\Cxf\apache-cxf-3.0.4\bin>wsdl2java -d D:\temp\src -client http://localhost:8080/CXFWS/webservice/helloworld?wsdl

其中?GreetingService_GreetingServicePort_Client 便是CXF自动生成的测试类，稍作修改便可调用：

public class Test { private static final QName SERVICE_NAME = new QName("ws.test.gary.com", "hello"); public static void main(String[] args) { URL wsdlURL = Hello.WSDL_LOCATION; Hello ss = new Hello(wsdlURL, SERVICE_NAME); GreetingService port = ss.getGreetingServicePort(); { System.out.println("Invoking greeting..."); String res = port.greeting("Bob"); System.out.println("greeting.result=" + res); } } }

三、wsimport 客户端

JDK自带工具生成代码：可以指定包结构，命令为：

wsimport -s D:\temp\src -p com.aisino.dz.sbsj.webservice -keep ?http://localhost:8080/CXFWS/webservice/helloworld?wsdl

生成的代码结构：

调用方式：

public class Test { public static void main(String[] args) { //创建要访问的服务的对象 Hello service = new Hello(); //通过getXxxPort方法获得代理类 GreetingService port = service.getGreetingServicePort(); //调用方法 String res = port.greeting("Andy"); System.out.println(res); } }
