开发工具:MyEclipse 6.0
开发环境:
1. jdk1.5
2. CXF框架,版本apache-cxf-2.2.3.zip,到http://cxf.apache.org/download.html下载
注:如使用jdk1.6进行开发,需下载jaxb-api.jar和jaxws-api.jar,然后在本机安装JDK的地方,在jdk1.6.0的jre文件夹下的lib文件夹中新建endorsed文件夹,放入以上两个jar包才可以进行开发。
第一步,先在MyEclipse新建一个java项目,项目名为HelloWebService。
第二步,在项目中引入apache-cxf-2.2.3.zip中lib下的所有jar包。
第三步,编写测试用接口以及其实现类:
接口:
Java代码
- package test;
- import javax.jws.WebService;
- public interface Hello {
- public String sayHello(String str);
- }
package test; import javax.jws.WebService; public interface Hello { public String sayHello(String str); }
实现类:
Java代码
- package test;
- public class HelloImpl implements Hello {
- public String sayHello(String str) {
- System.out.println("调用成功");
- return "Hello " + str;
- }
- }
package test; public class HelloImpl implements Hello { public String sayHello(String str) { System.out.println("调用成功"); return "Hello " + str; } }
在接口中添加WebService的注解,将其标注为WebService的服务接口。
Java代码
- @WebService
- public interface Hello {
@WebService public interface Hello {
第四步,编写WebService的服务器端。
Java代码
- package test;
- import org.apache.cxf.endpoint.Server;
- import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
- public class MainServer {
- public static void main(String[] args) {
- JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
- factory.setAddress("http://localhost:8080/HelloWebService");
- factory.setServiceClass(HelloImpl.class);
- Server server = factory.create();
- server.start();
- }
- }
package test; import org.apache.cxf.endpoint.Server; import org.apache.cxf.jaxws.JaxWsServerFactoryBean; public class MainServer { public static void main(String[] args) { JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean(); factory.setAddress("http://localhost:8080/HelloWebService"); factory.setServiceClass(HelloImpl.class); Server server = factory.create(); server.start(); } }
factory.setAddress("http://localhost:8080/HelloWebService");
设置服务在服务器上部署的位置
factory.setServiceClass(HelloImpl.class);
设置服务暴露的接口实现类
完成之后运行MainServer中的main方法。
注:因为CXF框架中有Jetty 6 服务器,所以这个的demo发布在其中运行。
之后打开浏览器,输入:
http://localhost:8080/HelloWebService?wsdl
如能看见以下画面则WebService发布成功:
Xml代码
- <?xml version="1.0" encoding="UTF-8" ?>
- - <wsdl:definitions name="HelloImplService" targetNamespace="http://test/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://test/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
- - <wsdl:types>
- - <xs:schema elementFormDefault="unqualified" targetNamespace="http://test/" version="1.0" xmlns:tns="http://test/" xmlns:xs="http://www.w3.org/2001/XMLSchema">
- <xs:element name="sayHello" type="tns:sayHello" />
- <xs:element name="sayHelloResponse" type="tns:sayHelloResponse" />
- - <xs:complexType name="sayHello">
- - <xs:sequence>
- <xs:element minOccurs="0" name="arg0" type="xs:string" />
- </xs:sequence>
<?xml version="1.0" encoding="UTF-8" ?> - <wsdl:definitions name="HelloImplService" targetNamespace="http://test/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://test/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> - <wsdl:types> - <xs:schema elementFormDefault="unqualified" targetNamespace="http://test/" version="1.0" xmlns:tns="http://test/" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="sayHello" type="tns:sayHello" /> <xs:element name="sayHelloResponse" type="tns:sayHelloResponse" /> - <xs:complexType name="sayHello"> - <xs:sequence> <xs:element minOccurs="0" name="arg0" type="xs:string" /> </xs:sequence>
第五步,编写客户端
Java代码
- package test;
- import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
- public class Client {
- public static void main(String[] args) {
- JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
- factory.setServiceClass(Hello.class);
- factory.setAddress("http://localhost:8080/HelloWebService");
- Hello hello = (Hello)factory.create();
- System.out.println(hello.sayHello("weberyb"));
- }
- }
package test; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; public class Client { public static void main(String[] args) { JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.setServiceClass(Hello.class); factory.setAddress("http://localhost:8080/HelloWebService"); Hello hello = (Hello)factory.create(); System.out.println(hello.sayHello("weberyb")); } }
factory.setServiceClass(Hello.class);
设置访问服务器端的指定接口。
factory.setAddress("http://localhost:8080/HelloWebService");
设置访问的服务的地址。
factory.create()
创建代理对象以供远程调用
之后运行Client中main方法,可以在控制台的服务器端看见如下输出:
Java代码
- ....................
- 2009-8-13 14:00:42 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
- 信息: Creating Service {http://test/}HelloService from class test.Hello
- Hello weberyb
.................... 2009-8-13 14:00:42 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass 信息: Creating Service {http://test/}HelloService from class test.Hello Hello weberyb
说明客户端调用WebService成功。
至此,这个简单的WebService开发完毕 尝试过jdk1.6 它的包会变成import org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean; 并且没有factory.setAddress这个方法 采用自带的例子进行测试 会出现参数null错误,但是客户端调用服务器端都调用成功,可能原因是没有加载那两个JAR文件的问题,暂时没有测试
