java webservice

创建一个 webService 工程。

2. 创建一个普通 Java 类

package com.hmw.jaxws;
/**
* 提供 WebService 服务的测试类<br>
* <b>注意：</b>该类必须有一个无参构造方法，否则无法使用 MyEclipse 的向导为此类创建 jax-ws 的 webService 服务端类<br>
* <b>创建日期</b>：2011-1-17
* @author <a href="mailto:hemingwang0902@126.com" mce_href="mailto:hemingwang0902@126.com">何明旺</a>
*/
publicclass HelloJaxws {
public String sayHello(String userName) {
return userName + "，您好，这是我的第一个 jax-ws 程序。";
}
publicint add(int i, int j) {
return i + j;
}
}

package com.hmw.jaxws;
/**
 * 提供 WebService 服务的测试类<br>
 * <b>注意：</b>该类必须有一个无参构造方法，否则无法使用 MyEclipse 的向导为此类创建 jax-ws 的 webService 服务端类<br>
 * <b>创建日期</b>：2011-1-17
 * @author <a href="mailto:hemingwang0902@126.com" mce_href="mailto:hemingwang0902@126.com">何明旺</a>
 */
public class HelloJaxws {
    public String sayHello(String userName) {
        return userName + "，您好，这是我的第一个 jax-ws 程序。";
    }
    public int add(int i, int j) {
        return i + j;
    }
}

package com.hmw.jaxws; /** * 提供 WebService 服务的测试类<br> * <b>注意：</b>该类必须有一个无参构造方法，否则无法使用 MyEclipse 的向导为此类创建 jax-ws 的 webService 服务端类<br> * <b>创建日期</b>：2011-1-17 * @author <a href="mailto:hemingwang0902@126.com" mce_href="mailto:hemingwang0902@126.com">何明旺</a> */ public class HelloJaxws { public String sayHello(String userName) { return userName + "，您好，这是我的第一个 jax-ws 程序。"; } public int add(int i, int j) { return i + j; } }

3. 创建 webService 服务端

HelloJaxwsDelegate.java 的源代码如下：

package com.hmw.jaxws;
@javax.jws.WebService(targetNamespace = "http://jaxws.hmw.com/", serviceName = "HelloJaxwsService", portName = "HelloJaxwsPort", wsdlLocation = "WEB-INF/wsdl/HelloJaxwsService.wsdl")
publicclass HelloJaxwsDelegate {
com.hmw.jaxws.HelloJaxws helloJaxws = new com.hmw.jaxws.HelloJaxws();
public String sayHello(String userName) {
return helloJaxws.sayHello(userName);
}
publicint add(int i, int j) {
return helloJaxws.add(i, j);
}
}

package com.hmw.jaxws;
@javax.jws.WebService(targetNamespace = "http://jaxws.hmw.com/", serviceName = "HelloJaxwsService", portName = "HelloJaxwsPort", wsdlLocation = "WEB-INF/wsdl/HelloJaxwsService.wsdl")
public class HelloJaxwsDelegate {
    com.hmw.jaxws.HelloJaxws helloJaxws = new com.hmw.jaxws.HelloJaxws();
    public String sayHello(String userName) {
        return helloJaxws.sayHello(userName);
    }
    public int add(int i, int j) {
        return helloJaxws.add(i, j);
    }
}

package com.hmw.jaxws; @javax.jws.WebService(targetNamespace = "http://jaxws.hmw.com/", serviceName = "HelloJaxwsService", portName = "HelloJaxwsPort", wsdlLocation = "WEB-INF/wsdl/HelloJaxwsService.wsdl") public class HelloJaxwsDelegate { com.hmw.jaxws.HelloJaxws helloJaxws = new com.hmw.jaxws.HelloJaxws(); public String sayHello(String userName) { return helloJaxws.sayHello(userName); } public int add(int i, int j) { return helloJaxws.add(i, j); } }

4. 导入相关的 jar 包，并将项目布署到 tomcat，启动 tomcat.

整个项目的目录结构如下图所示：

5. 创建 webService 客户端项目（普通 Java 项目）。

6. 创建客户端相关调用类

7. 创建测试类

测试类 ClientTest.java 的代码如下：

package com.hmw.client.jaxws;
publicclass ClientTest {
publicstaticvoid main(String[] args) {
HelloJaxwsDelegate service = new HelloJaxwsService().getHelloJaxwsPort();
System.out.println(service.sayHello("hemingwang"));
System.out.println("result is: " + service.add(1, 2));
}
}

package com.hmw.client.jaxws;
public class ClientTest {
    public static void main(String[] args) {
        HelloJaxwsDelegate service = new HelloJaxwsService().getHelloJaxwsPort();
            System.out.println(service.sayHello("hemingwang"));
            System.out.println("result is: " + service.add(1, 2));
        }
    }

package com.hmw.client.jaxws; public class ClientTest { public static void main(String[] args) { HelloJaxwsDelegate service = new HelloJaxwsService().getHelloJaxwsPort(); System.out.println(service.sayHello("hemingwang")); System.out.println("result is: " + service.add(1, 2)); } }

整个项目的目录结构如下图所示：

8. 运行测试类

运行结果如下图所示：
