基于java api 和 servlet发布WebService(二)

一、环境

JDK1.6以上

二、 WebService 服务端编码

1. New -> Web Project, 名称为webService-server

2. 编写server端代码，如下：

package com.calvin.service;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

@WebService(targetNamespace="http://demo.calvin.test/sayHi")
@SOAPBinding(style=Style.RPC)
public class MyService {

@WebMethod(operationName = "say")
public String sayHello(@WebParam(name = "name") String msg) {
return "Hello :" + msg;
}
}

3. 创建发布WebService的servlet类

编码如下：

package com.calvin.servlet;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.xml.ws.Endpoint;

import com.calvin.service.MyService;

public class WebServiceLoader extends HttpServlet {

private static final long serialVersionUID = 1L;

public WebServiceLoader() {
super();
}

public void destroy() {
super.destroy();
}

public void init() throws ServletException {
System.out.println("Web Service发布中......");

Endpoint.publish("http://0.0.0.0:8081/Hello", new MyService());

System.out.println("Web Service发布完成");
}

}

4. 在web.xml中配置Servlet类

配置如下：

<servlet>
<servlet-name>WebServiceLoader</servlet-name>
<servlet-class>com.calvin.servlet.WebServiceLoader</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

三、部署webService-server项目到Tomcat，并启动Tomcat服务

四、查看wsdl

浏览器输入  http://localhost:8081/Hello?wsdl
