java webservice
一、发布一个webservice服务。
/**
*
* 基于soap协议(http+xml)的服务
*/
@WebService(name = "Login",// 定义Port名称
serviceName = "MyService", // 修改WebService服务名称
targetNamespace = "http://com.soft.ws/my" // 定义命名空间,默认为倒置的包名
)
public interface MyService {
// 提供一个对外公开的服务
@WebMethod(operationName = "authorization")
// 修改方法名
String authorization(@WebParam(name = "userId") String userId,
@WebParam(name = "password") String password);
}
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
/**
* 服务实现类
*/
@WebService(endpointInterface = "com.soft.platform.webservice.server.MyService",
name = "Login",// 定义Port名称
serviceName = "MyService", // 修改WebService服务名称
targetNamespace = "http://com.soft.ws/my" // 定义命名空间,默认为倒置的包名
//服务实现类和接口的注解要一样全
)
public class MyServiceImpl implements MyService {
@WebMethod(operationName = "authorization" // 修改方法名
)
@Override
public String authorization(
@WebParam(name = "userId") String userId,
@WebParam(name = "password") String password) {
if ("admin".equals(userId) && "123456".equals(password)) {
return "success";
}
return "ERROR";
}
}
/**
* 发布服务
*
*/
public class MyPublisher {
public static void main(String[] args) {
//指定服务url
String url = "http://192.168.0.101:8089/myservice";
//指定服务实现类
MyService server = new MyServiceImpl();
//采用命令行发布者Endpoint发布服务
Endpoint.publish(url, server);
}
}
二、几种客户端调用方式
1、jdk原生调用(需要获取服务接口文件)
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import com.soft.platform.webservice.server.MyService;
public class WsClient {
public static void main(String[] args) throws Exception {
URL url = new URL("http://192.168.0.101:8089/myservice?wsdl");
// 指定命名空间和服务名称
QName qName = new QName("http://com.soft.ws/my", "MyService");
Service service = Service.create(url, qName);
// 通过getPort方法返回指定接口
MyService myServer = service.getPort(new QName("http://com.soft.ws/my",
"LoginPort"), MyService.class);
// 调用方法 获取返回值
String result = myServer.authorization("admin", "123456");
System.out.println(result);
}
}
返回结果: success
2.import生成客户端代码
wsimport -d d:/webservice -keep -p com.soft.test.wsimportClient -verbose http://192.168.0.101:8089/myservice?wsdl
public static void main(String[] args) {
MyService_Service service = new MyService_Service();
MyService login = service.getLoginPort();
String result = login.authorization("admin", "123456");
System.out.println(result);
}
3、cxf两种调用方式。
public static void main(String[] args) {
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(MyService.class);
factory.setAddress("http://192.168.0.101:8089/myservice?wsdl");
// 需要服务接口文件
MyService client = (MyService) factory.create();
String result = client.authorization("admin", "123456");
System.out.println(result);
}
public static void main(String[] args) throws Exception {
//采用动态工厂方式 不需要指定服务接口
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newinstance();
Client client = dcf
.createClient("http://192.168.0.101:8089/myservice?wsdl");
QName qName = new QName("http://com.soft.ws/my", "authorization");
Object[] result = client.invoke(qName,
new Object[] { "admin", "123456" });
System.out.println(result[0]);
}
4、axis调用方式
import java.net.MalformedURLException;
import java.net.URL;
import java.rmi.RemoteException;
import javax.xml.namespace.QName;
import javax.xml.rpc.parameterMode;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
public class WsAClient {
/**
* 跨平台调用Web Service出现
* faultString: 服务器未能识别 HTTP 头 SOAPAction 的值:
* JAX-WS规范不需要SoapAction,但是.NET需要,所以产生了这个错误。
* options.setAction("目标的TargetNameSpace"+"调用的方法名");
*/
public static void main(String[] args) {
String url = "http://192.168.0.101:8089/myservice?wsdl";
Service service = new Service();
try {
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new URL(url));
// WSDL里面描述的接口名称(要调用的方法)
call.setOperationName(new QName("http://com.soft.ws/my",
"authorization"));
//跨平台调用加上这个
call.setUseSOAPAction(true);
call.setSOAPActionURI("http://com.soft.ws/my/authorization");
// 接口方法的参数名, 参数类型,参数模式 IN(输入), OUT(输出) or INOUT(输入输出)
call.addParameter("userId", XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter("password", XMLType.XSD_STRING, ParameterMode.IN);
// 设置被调用方法的返回值类型
call.setReturnType(XMLType.XSD_STRING);
// 设置方法中参数的值
Object result = call.invoke(new Object[] { "admin", "123456" });
System.out.println(result.toString());
} catch (ServiceException | RemoteException | MalformedURLException e) {
e.printstacktrace();
}
}
}
axis方式依赖的相关jar包如下:
5、httpclient调用方式。
(1)maven依赖如下
<properties>
<httpclient.version>4.5.6</httpclient.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>${httpclient.version}</version>
</dependency>
</dependencies>
(2)httpclient作为客户端调用webservice。代码如下
/*
* Copyright (c)
*/
package test;
import org.apache.http.client.config.requestConfig;
import org.apache.http.client.methods.CloseableHttpresponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import java.nio.charset.Charset;
/**
* webservice客户端

* @author David Lin
* @version: 1.0

*/
public class SoapClient {
public static void main(String args[]) throws Exception {
//soap服务地址
String url = "http://localhost:8888/ssm/Services/UserService?wsdl";
stringbuilder soapBuilder = new StringBuilder(64);
soapBuilder.APPend("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
soapBuilder.append("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://webservice.soft.com/\">");
soapBuilder.append(" <soapenv:Header/>");
soapBuilder.append(" <soapenv:Body>");
soapBuilder.append(" <web:authorization>");
soapBuilder.append(" <userId>").append("admin").append("</userId>");
soapBuilder.append(" <password>").append("123456").append("</password>");
soapBuilder.append(" </web:authorization>");
soapBuilder.append(" </soapenv:Body>");
soapBuilder.append("</soapenv:Envelope>");
//创建httpcleint对象
CloseableHttpClient httpClient = HttpClients.createDefault();
//创建http Post请求
HttpPost httpPost = new HttpPost(url);
// 构建请求配置信息
RequestConfig config = RequestConfig.custom().setConnectTimeout(1000) // 创建连接的最长时间
.setConnectionRequestTimeout(500) // 从连接池中获取到连接的最长时间
.setsocketTimeout(3 * 1000) // 数据传输的最长时间10s
.build();
httpPost.setConfig(config);
CloseableHttpResponse response = null;
try {
//采用SOAP1.1调用服务端,这种方式能调用服务端为soap1.1和soap1.2的服务
httpPost.setHeader("content-Type", "text/xml;charset=UTF-8");
//采用SOAP1.2调用服务端,这种方式只能调用服务端为soap1.2的服务
// httpPost.setHeader("Content-Type", "application/soap+xml;charset=UTF-8");
StringEntity stringEntity = new StringEntity(soapBuilder.toString(), Charset.forName("UTF-8"));
httpPost.setEntity(stringEntity);
response = httpClient.execute(httpPost);
// 判断返回状态是否为200
if (response.getStatusLine().getStatusCode() == 200) {
String content = EntityUtils.toString(response.getEntity(), "UTF-8");
System.out.println(content);
} else {
System.out.println("调用失败!");
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (null != response) {
response.close();
}
if (null != httpClient) {
httpClient.close();
}
}
}
}
返回结果为:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns2:authorizationResponse xmlns:ns2="http://webservice.soft.com/">
<return>success</return>
</ns2:authorizationResponse>
</soap:Body>
</soap:Envelope>
(3)用Jsoup提取响应数据。
maven依赖
<properties>
<jsoup.version>1.11.3</jsoup.version>
</properties>
<dependencies>
<dependency>
<groupId>org.jsoup</groupId>
<artifactId>jsoup</artifactId>
<version>${jsoup.version}</version>
</dependency>
</dependencies>
代码如下:
Document soapRes = Jsoup.parse(content);
Elements returnEle = soapRes.getElementsByTag("return");
System.out.println("调用结果为:"+returnEle.text());
