java调用webService接口的几种方法

webservice的发布一般都是使用WSDL（web service descriptive language）文件的样式来发布的，在WSDL文件里面，包含这个webservice暴露在外面可供使用的接口。

1.可以通过带有webservice插件的Eclipse直接生成调用webservice客户端代码

在Eclipse中生成webservice客户端代码，New---->Other---->Webservice---->Webservice Client,选择之前拷贝到eclipse中的wsdl路径点击finish,这样eclipse就帮我们自动生成了webservice的客户端,接下来只需在程序中调用即可,在程序中调用eclipse自动生成的webservice客户端;

生成的客户端代码：

测试案例：

2.使用axis1.4或2.X生成webservice的客户端代码

1、下载axis1.4，解压；
2、在axis-1_4目录下新建wsdl2java-client.bat（.bat批处理文件，可任意命名）文件，增加内容如下：

set Axis_Lib=.\lib
set Java_Cmd=java -Djava.ext.dirs=%Axis_Lib%
%Java_Cmd% org.apache.axis.wsdl.WSDL2Java   -p com.lmb.client.ws C:\Users\Administrator\Desktop\axis-1_4\axis-1_4\lmbtest.xml
pause

注意：其中com.lmb.client.ws为生成的客户端代码的包路径，C:\Users\Administrator\Desktop\axis-1_4\axis-1_4\lmbtest.xml为wsdl文件。

3、双击wsdl2java-client.bat：

可以看到相关路径下生成的客户端代码如下：

4、调用方法如下：

public class WebServiceClientTest{public static void main(String[] args){String wsdl = "http://xxx.xxx.xx.xx:8082/csp/services/c_lttb/orderToHeLiWebservice";String requestStr = "";// 有些webservice需要登录，登陆后才能进行一些操作，这个需要设置如下两个参数： //1、 超时时间 stub.setTimeout(1000 * 60 * 20); //2、 次数设置true，登录后才能保持登录状态，否则第二次调用ws方法时仍然会提示未登录。 stub.setMaintainSession(true);org.apache.axis.client.Service service = new org.apache.axis.client.Service();OrderToHeLiWebserviceHttpBindingStub stub = new OrderToHeLiWebserviceHttpBindingStub(new java.net.URL(wsdl), service);String response = stub.urgeWorkOrderServiceSheet(requestStr); //调用ws提供的方法System.out.println("response >>> " + response);}
}

3.手写客户端代码方式

新建一个maven工程

pom.xml添加jar依赖：

<dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><!--axis2 begin--><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-spring</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-transport-http</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-transport-local</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-xmlbeans</artifactId><version>${axis2.version}</version></dependency><!--axis2 end--><dependency><groupId>org.apache.ant</groupId><artifactId>ant</artifactId><version>1.9.7</version></dependency><dependency><groupId>org.jdom</groupId><artifactId>jdom</artifactId><version>2.0.2</version></dependency><dependency><groupId>commons-net</groupId><artifactId>commons-net</artifactId><version>3.3</version></dependency><dependency><groupId>javax.mail</groupId><artifactId>javax.mail-api</artifactId><version>1.4.7</version></dependency><dependency><groupId>javax.mail</groupId><artifactId>mail</artifactId><version>1.4.7</version></dependency><dependency><groupId>javax.activation</groupId><artifactId>activation</artifactId><version>1.1.1</version></dependency><!-- https://mvnrepository.com/artifact/axis/axis --><dependency><groupId>axis</groupId><artifactId>axis</artifactId><version>1.4</version></dependency></dependencies>

客户端代码：

（1）这里是用axis调用的我自己写的代码由于我的服务端接口比较老所以我采用这种方式成功上传了数据但是传输的附件大小只能不超过20k，超过了就报系统找不到指定的路径，暂时不知道为什么，希望知道的人告知下

package com.TestWebService.WebService;import java.io.File;import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.xml.namespace.QName;import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory;
import org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory;public class AxisToWebServiceImportData {public String invokeByAxis() {boolean result = false;Service service = new Service();String endPoint = "http://192.168.0.***:8080/ESWebService/services/DataInterfaceService";try {Call call = (Call) service.createCall();call.setTargetEndpointAddress(endPoint);call.setEncodingStyle("utf-8");String srcFilePath = "D:\\sip-data.zip";String userName = "admin";String password = "*****";String flk_id = "27";String wjm = "wj1327";String zipName = "sip-data.zip";String encode = "92BBE4B3******067E9E5F17";DataHandler dh = new DataHandler(new FileDataSource(srcFilePath));QName qnameattachment = new QName("DataInterfaceService", "DataHandler");call.registerTypeMapping(dh.getClass(),qnameattachment,JAFDataHandlerSerializerFactory.class,JAFDataHandlerDeserializerFactory.class);call.addParameter("dh", qnameattachment, javax.xml.rpc.ParameterMode.IN);call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);call.addParameter("password", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);call.addParameter("flk_id", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);call.addParameter("wjm", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);call.addParameter("zipName", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);call.addParameter("encode", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);call.setReturnType(org.apache.axis.encoding.XMLType.XSD_BOOLEAN);call.setOperationName(new QName(endPoint,"importData"));result = (Boolean) call.invoke(new Object[]{dh,userName,password,flk_id,wjm,zipName,encode});System.out.println("返回值：" + result);} catch (Exception e) {System.out.print("WebService请求异常！！ ");e.printStackTrace();}return "true";}public static void main(String[] args) {AxisToWebServiceImportData a = new AxisToWebServiceImportData();a.invokeByAxis();}
}

（2）第二种方式是用RPC方式调用

package com.TestWebService.WebService;import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.xml.namespace.QName;import org.apache.axiom.om.OMElement;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
import org.apache.axis2.transport.http.HTTPConstants;import org.apache.tools.zip.ZipEntry;
import org.apache.tools.zip.ZipFile;import org.jdom2.Attribute;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.DOMBuilder;
import org.jdom2.input.SAXBuilder;
import org.jdom2.output.DOMOutputter;
import org.jdom2.xpath.XPath;public class ImportData {public boolean TestWebService() {boolean result = false;try {RPCServiceClient serviceClient = new RPCServiceClient();String url = "http://192.168.0.207:8080/ESWebService/services/DataInterfaceService";// 指定调用WebService的URLEndpointReference targetEPR = new EndpointReference(url);Options options = serviceClient.getOptions();// 确定目标服务地址options.setTo(targetEPR);// 确定调用方法options.setAction("importData");options.setProperty(HTTPConstants.CHUNKED, "false");// 把chunk关掉后，会自动加上Content-Length//解决高并发链接超时问题options.setManageSession(true);options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT,true);//设置响应超时，默认5soptions.setProperty(HTTPConstants.SO_TIMEOUT, 5000);//设置连接超时，默认5soptions.setProperty(HTTPConstants.CONNECTION_TIMEOUT, 5000);String srcFilePath = "D:\\sip-data.zip";String userName = "admin";String password = "*****";String flk_id = "27";String wjm = "wj1327";String zipName = "sip-data.zip";String encode = "92BBE4B*****93A067E9E5F17";DataHandler dh = new DataHandler(new FileDataSource(new File(srcFilePath)));System.out.println("dh:::" + dh);// 指定方法的参数值Object[] parameters = new Object[] {dh,userName,password,flk_id,wjm,zipName,encode};// 创建服务名称// 1.namespaceURI - 命名空间地址 (wsdl文档中的targetNamespace)// 2.localPart - 服务视图名 (wsdl文档中operation的方法名称，例如<wsdl:operation name="getMobileCodeInfo">)QName qname = new QName("http://192.168.0.***:8080/ESWebService/services/DataInterfaceService", "importData");// 指定方法返回值的数据类型的Class对象Class[] returnTypes = new Class[] {Boolean.class};Object[] response = serviceClient.invokeBlocking(qname, parameters,returnTypes);
//            OMElement element = serviceClient.invokeBlocking(qname, parameters);
//            System.out.println("element::" + element);/** 值得注意的是，返回结果就是一段由OMElement对象封装的xml字符串。* 我们可以对之灵活应用,下面我取第一个元素值，并打印之。因为调用的方法返回一个结果*/
//            result = element.getFirstElement().getText();
//            System.out.println(result);result =   (Boolean) response[0];} catch (AxisFault e) {// TODO 自动生成的 catch 块e.printStackTrace();}return result;}public static void main(String[] args) {ImportData t = new ImportData();System.out.println("result:::"+ t.TestWebService());}
}

(3) 应用document方式调用用ducument方式应用现对繁琐而灵活，引入相应的axis2的jar包

package com.TestWebService.WebService;import java.io.File;import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.xml.namespace.QName;import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axiom.om.OMText;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;public class ImportDataTwo {public boolean TestImportData() {boolean res = false;try {ServiceClient serviceClient = new ServiceClient();//创建服务地址WebService的URL,注意不是WSDL的URLString url = "http://192.168.0.207:8080/ESWebService/services/DataInterfaceService";EndpointReference targetEPR = new EndpointReference(url);Options options = serviceClient.getOptions();options.setTo(targetEPR);//确定调用方法（wsdl 命名空间地址 (wsdl文档中的targetNamespace) 和 方法名称 的组合）options.setAction("http://192.168.0.207:8080/ESWebService/services/DataInterfaceService/importData");OMFactory fac = OMAbstractFactory.getOMFactory();/** 指定命名空间，参数：* uri--即为wsdl文档的targetNamespace，命名空间* perfix--可不填*/OMNamespace omNs = fac.createOMNamespace("http://192.168.0.***:8080/ESWebService/services/DataInterfaceService", "");// 指定方法OMElement method = fac.createOMElement("importData", omNs);// 指定方法的参数OMElement userName = fac.createOMElement("userName", omNs);userName.setText("admin");OMElement password = fac.createOMElement("password", omNs);password.setText("*****");String srcFilePath = "D:\\sip-data.zip";DataHandler dh2 = new DataHandler(new FileDataSource(new File(srcFilePath)));OMText textData = fac.createOMText(dh2, true);OMElement dh = fac.createOMElement("dh", omNs);dh.addChild(textData);System.out.println("dh:::" + dh2);OMElement flk_id = fac.createOMElement("flk_id", omNs);flk_id.setText("27");OMElement wjm = fac.createOMElement("wjm", omNs);wjm.setText("wj1327");OMElement zipName = fac.createOMElement("zipName", omNs);zipName.setText("sip-data.zip");OMElement encode = fac.createOMElement("encode", omNs);encode.setText("92BBE4B3BC*****393A067E9E5F17");method.addChild(dh);method.addChild(userName);method.addChild(password);method.addChild(flk_id);method.addChild(wjm);method.addChild(zipName);method.addChild(encode);// method.build();System.out.println(method);//远程调用web服务OMElement result = serviceClient.sendReceive(method);System.out.println(result);} catch (AxisFault axisFault) {axisFault.printStackTrace();}return true;}public static void main(String[] args) {ImportDataTwo t = new ImportDataTwo();t.TestImportData();}
}

暂时只接触到这么多webservice调用方式，码下来当作学习笔记了
