webservice篇之高级开发（四）

通过ajax与jquery访问webservice服务端数据.这里涉及到域的问题。但这不是重点！

首先我们发布一个接口：

接口类：

package com.azj.service;

import javax.jws.WebService;

@WebService
public interface oderSel {
public String getName(String name);

}

接口实现代码：

package com.azj.service;

import javax.jws.WebService;

@WebService(endpointInterface="com.azj.service.oderSel",serviceName="orderSeiImpl")
public class orderSeiImpl implements oderSel {

@Override
public String getName(String name) {

return "你好："+name;
}

}

发布：

package com.azj.service;

import javax.xml.ws.Endpoint;

public class Te {

public static void main(String[] args) {
EndpointImpl endimpl=(EndpointImpl)Endpoint.publish("http://localhost:8080/fb", new orderSeiImpl());

endimpl.getInInterceptors().add(new logininterceptor())；
System.out.println("发布成功！");

}

}

在游览器上输入访问http://localhost:8080/fb?wsdl 看是否生成xml文档。

访问页面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>艾壹系统－AYXT</title>
<link rel="shortcut icon" href="<%=request.getContextPath()%>/images/pu.ico"/>
<link type="text/css" rel="stylesheet" media="all" href="<%=request.getContextPath()%>/styles/global.css" />
<link type="text/css" rel="stylesheet" media="all" href="<%=request.getContextPath()%>/styles/global_color.css" />
<script src="/ajaxsel/js/jquery-3.0.0.min.js" type="text/javascript"></script>
<script>
$(function(){
$("#tj").click(function(){
//clientServlet一个servlet,这里必须通过servlet来进行访问
$.post("clientServlet",{"name":$("#name").val()},function(data){
alert($(data).text());

});
});

});
</script>

</head>
<body>
<center>
username:<input type="text" id="name"/>
<input type="button" id="tj" value="jquery.click"/>
</center>
</body>
</html>

下面是servlet类：主要的东西

package com.client.servlet;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
* Servlet implementation class clientServlet
*/
@WebServlet("/clientServlet")
public class clientServlet extends HttpServlet {
private static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String name = request.getParameter("name");
String data="<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soap:Body><ns2:getName xmlns:ns2=\"http://interceptor.service.com/\"><arg0>"+name+"</arg0></ns2:getName></soap:Body></soap:Envelope>";

//webservice参数，这里的参数哪里来的呢，这里为啥qian部分服务端发布的代码里添加

//endimpl.getInInterceptors().add(new logininterceptor())的原因啦，你必须先进行访问一次，你可以通过wsdl文档生成相应的类，进行调用（较笨的一种方法）你也可以通过开发工具里的webservice浏览器进行访问，效果一样的，服务端就会生成一段响应数据的代码：在开发工具的Console下：

/*<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:q0="http://wether/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<q0:send>
<arg0>rainjm</arg0>
</q0:send>
</soapenv:Body>
</soapenv:Envelope>*/

//通过修饰下就是上面所展示的。
URL url=new URL("http://localhost:8080/fb");//webservice请求路径
HttpURLConnection con=(HttpURLConnection) url.openConnection();//HttpsURLConnection进行跨域请求

//con.setRequestMethod("post");//请求方式
con.setDoOutput(true);//是否获取写入服务端数据
con.setDoInput(true);//是否接受服务端数据；
con.setRequestProperty("Content-type", "text-xml;charset=utf-8");//设置写入编码方式

OutputStream out = con.getOutputStream();
out.write(data.getBytes("utf-8"));//写入数据

int code = con.getResponseCode();
if(code==200){//判断是否请求成功
InputStream in = con.getInputStream();
System.out.println(in.available());

response.setContentType("text-xml;charset=utf-8");//响应数据编码
ServletOutputStream outputStream = response.getOutputStream();//写入数据到ajax里去
byte[]buff=new byte[1024];
int len=0;
while((len=in.read(buff))!=-1){
outputStream.write(buff, 0, len);
}
outputStream.flush();
}

}

}

这下就完成啦。
