java简单实现webservice接口

webservice实现有多种方式

比如最常用的有axis框架，xfire框架，通过该框架可以发布wsdl接口，也可以实现webservice客户端，目前eclipse都有集成的插件，可以根据wsdl文件生成webservice客户端调用接口，但是这样部署的时候必须依赖框架的jar包，有时候可能因为环境等等原因，我们仅仅需要wsdl中的某一个接口，这时候可以通过http接口或socket接口直接发生xml数据，来调用服务端webservice服务，其实 webservice底层还是发送xml数据，只是框架封装了对xml数据进行序列化与反序列化操作，下面以两个简单的例子说明http方式和 socket方式。

http实现webservice接口调用例子：

[c-sharp] view plain copy

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
public class HttpPostTest {
void testPost(String urlStr) {
try {
URL url = new URL(urlStr);
URLConnection con = url.openConnection();
con.setDoOutput(true);
con.setRequestProperty("Pragma:", "no-cache");
con.setRequestProperty("Cache-Control", "no-cache");
con.setRequestProperty("Content-Type", "text/xml");
OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream());
String xmlInfo = getXmlInfo();
out.write(new String(xmlInfo));
out.flush();
out.close();
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
String line = "";
StringBuffer buf = new StringBuffer();
for (line = br.readLine(); line != null; line = br.readLine()) {
buf.append(new String(line.getBytes(),"UTF-8"));
}
System.out.println(buf.toString());
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private String getXmlInfo() {
// 通过wsdl文件可以查看接口xml格式数据，构造调用接口xml数据
String xml = "<SOAP-ENV:Envelope xmlns:SOAP-ENV=/"http://schemas.xmlsoap.org/soap/envelope//" xmlns:SOAP-ENC=/"http://schemas.xmlsoap.org/soap/encoding//" xmlns:xsi=/"http://www.w3.org/2001/XMLSchema-instance/" xmlns:xsd=/"http://www.w3.org/2001/XMLSchema/">"
+ "<SOAP-ENV:Body>"
+ "<m:getItemDetailSingle xmlns:m=/"http:xxxxxxxxxxxxxxxxxx//">"
+ "<itemMo>"
+ "<category>工厂类</category>"
+ "<city>北京</city>"
+ "<flag>1</flag>"
+ "<itemId>0</itemId>"
+ "<itemIndex>1</itemIndex>"
+ "<keyword></keyword>"
+ "<mobile>2147483647</mobile>"
+ "<password>123456</password>"
+ "<userName>sohu</userName>"
+ "</itemMo>"
+ "</m:getItemDetailSingle>"
+ "</SOAP-ENV:Body>"
+ "</SOAP-ENV:Envelope>";
return xml;
}
public static void main(String[] args) throws UnsupportedEncodingException {
String url = "http://localhost:9003/dataService/services/Job";
new HttpPostTest().testPost(url);
}
}

socke方式实现例子：

[c-sharp] view plain copy

import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;
public class WebServiceClient {
/**
* @param args
* @throws IOException
* @throws UnknownHostException
*/
public static void main(String[] args) throws UnknownHostException, IOException {
Socket socket = new Socket("localhost",9003);
OutputStream os = socket.getOutputStream();
InputStream is = socket.getInputStream();
//System.out.println(socket.isConnected());
String httpSend = "POST /dataService/services/Job HTTP/1.1/r/n"
+ "Content-Type:text/xml/r/n"
+ "Host:localhost:9003/r/n"
+ "Content-Length:1024/r/n"
+ "/r/n"
+ "<SOAP-ENV:Envelope xmlns:SOAP-ENV=/"http://schemas.xmlsoap.org/soap/envelope//" xmlns:SOAP-ENC=/"http://schemas.xmlsoap.org/soap/encoding//" xmlns:xsi=/"http://www.w3.org/2001/XMLSchema-instance/" xmlns:xsd=/"http://www.w3.org/2001/XMLSchema/">"
+ "<SOAP-ENV:Body>"
+ "<m:getItemDetailSingle xmlns:m=/"http://localhost//">"
+ "<itemMo>"
+ "<category>工厂类</category>"
+ "<city>北京</city>"
+ "<flag>1</flag>"
+ "<itemId>0</itemId>"
+ "<itemIndex>1</itemIndex>"
+ "<keyword>String</keyword>"
+ "<mobile>2147483647</mobile>"
+ "<password>123456</password>"
+ "<userName>sohu</userName>"
+ "</itemMo>"
+ "</m:getItemDetailSingle>"
+ "</SOAP-ENV:Body>"
+ "</SOAP-ENV:Envelope>";
os.write(httpSend.getBytes());
os.flush();
InputStreamReader ireader = new InputStreamReader(is);
java.io.BufferedReader breader = new java.io.BufferedReader(ireader);
String responseLine = "";
while((responseLine = breader.readLine()) != null)
{
System.out.println(new String(responseLine.getBytes(),"UTF-8"));
}
System.out.println("");
}
}
