webservice 教程學習系列(五)——使用JDK開發webservice

1.開發伺服器端程式碼
webservice程式碼
1.建立介面
package ws;
import javax.jws.WebMethod;
import javax.jws.WebService;
/**
* SEI
* @author Administrator
*
*/
@WebService
public interface HelloWS {
/**
* 介面方法
* @param name
* @return
*/
@WebMethod
public String sayHello(String name);
}
2.建立介面實現類
package ws;
import javax.jws.WebService;
/**
* SEI實現類
* @author Administrator
*
*/
@WebService
public class HelloWSImpl implements HelloWS {
@Override
public String sayHello(String name) {
System.out.println("server sayHello"+name);
return "hello "+name;
}
}
3.終端endpoint釋出webservice
package ws; import javax.xml.ws.Endpoint; /** * 釋出webservice * endpoint * @author Administrator * */ public class HelloWSTest { public static void main(String[] args) { String address="http://192.168.43.220:8989/ws_test/zq"; Endpoint.publish(address, new HelloWSImpl()); System.out.println("釋出webservice成功！"); } }
按F11 執行終端，會發現執行成功，並且程序執行成功後未關閉，一直處於啟動狀態，說明色日女啟動之後一直處於啟動狀態，等待被連線。
2.開發客戶端程式碼
獲取webservice server的約束
JDK自帶的轉換工具可以實現：在本地JDK路徑：C:\Program Files\Java\jdk1.8.0_11\bin下有一個wsimport.exe，這個工具可以實現。
新建一個java project 為ws_client。在src處右鍵，在系統瀏覽器中開啟，進入sr路徑，按住shift，滑鼠右鍵，選擇“在此處開啟命令視窗”，進入dos視窗。
輸入命令：wsimport -keep http://192.168.43.220:8989/ws_test/zq?wsdl
即可將伺服器端的約束bean直接匯入進本專案工程的src目錄下。
回到eclipse的工程中，右鍵重新整理，即可看到已經匯入的bean.
其實在瀏覽器端輸入webservice的url也可以比較直觀的看到約束檔案：http://192.168.43.220:8989/ws_test/zq?wsdl
回到eclipse，看一下生成的檔案。找到根檔案。可以根據<service name="HelloWSImplService"> 得知根檔案是HelloWSImplService。ctrl+shift+T 輸入檔名，可以直接開啟給java檔案。
6份檔案原始碼如下所示：
1.HelloWSImpl
package ws;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.ws.Action;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2.9-b130926.1035
* Generated source version: 2.2
*
*/
@WebService(name = "HelloWSImpl", targetNamespace = "http://ws/")
@XmlSeeAlso({
ObjectFactory.class
})
public interface HelloWSImpl {
/**
*
* @param arg0
* @return
* returns java.lang.String
*/
@WebMethod
@WebResult(targetNamespace = "")
@RequestWrapper(localName = "sayHello", targetNamespace = "http://ws/", className = "ws.SayHello")
@ResponseWrapper(localName = "sayHelloResponse", targetNamespace = "http://ws/", className = "ws.SayHelloResponse")
@Action(input = "http://ws/HelloWSImpl/sayHelloRequest", output = "http://ws/HelloWSImpl/sayHelloResponse")
public String sayHello(
@WebParam(name = "arg0", targetNamespace = "")
String arg0);
}
2.HelloWSImplService

public class HelloWSImplService
extends Service
{

/**

*/
@WebEndpoint(name = "HelloWSImplPort")
public HelloWSImpl getHelloWSImplPort() {
return super.getPort(new QName("http://ws/", "HelloWSImplPort"), HelloWSImpl.class);
}
/**
*
* @param features
* A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy. Supported features not in the <code>features</code> parameter will have their default values.
* @return
* returns HelloWSImpl
*/
@WebEndpoint(name = "HelloWSImplPort")
public HelloWSImpl getHelloWSImplPort(WebServiceFeature... features) {
return super.getPort(new QName("http://ws/", "HelloWSImplPort"), HelloWSImpl.class, features);
}
private static URL __getWsdlLocation() {
if (HELLOWSIMPLSERVICE_EXCEPTION!= null) {
throw HELLOWSIMPLSERVICE_EXCEPTION;
}
return HELLOWSIMPLSERVICE_WSDL_LOCATION;

}
3.ObjectFactory
package ws;

/**

* Java content interface and Java element interface
* generated in the ws package.
* <p>An ObjectFactory allows you to programatically
* construct new instances of the Java representation
* for XML content. The Java representation of XML
* content can consist of schema derived interfaces
* and classes representing the binding of schema
* type definitions, element declarations and model
* groups. Factory methods for each of these are
* provided in this class.
*
*/
@XmlRegistry
public class ObjectFactory {
private final static QName _SayHello_QNAME = new QName("http://ws/", "sayHello");
private final static QName _SayHelloResponse_QNAME = new QName("http://ws/", "sayHelloResponse");
/**
* Create a new ObjectFactory that can be used to create new instances of schema derived classes for package: ws
*
*/
public ObjectFactory() {
}
/**
* Create an instance of {@link SayHello }
*
*/

*
*/

*
*/
@XmlElementDecl(namespace = "http://ws/", name = "sayHello")
public JAXBElement<SayHello> createSayHello(SayHello value) {
return new JAXBElement<SayHello>(_SayHello_QNAME, SayHello.class, null, value);

不知道為啥，最後兩個檔案中文亂碼了。我明明設定的整個workspace的編碼格式都是utf-8，知道為什麼的朋友歡迎在下面留言。
最後，我們就可以寫呼叫程式碼了。
package ws.test;
import ws.HelloWSImpl;
import ws.HelloWSImplService;
public class WSClientTest {
public static void main(String[] args) {
HelloWSImplService helloWSImplService=new HelloWSImplService();
HelloWSImpl helloWSImplPort = helloWSImplService.getHelloWSImplPort();
String response = helloWSImplPort.sayHello("zhangqin");
System.out.println("client接收到:"+response);
}
}
執行結果
到這裡，一個簡單的伺服器端和客戶端的程式碼就寫完了。
補充：剛剛突然知道了原來那個生成的bean必須是中文編碼，使用UTF-8就會亂碼，所以將其屬性手動改成gbk即可。
