Java 调用WebService三种简单的方式
下面我们来看Java如何通过WSDL文件来调用这些web service：
注意：不同版本的Axis相差很大，大家最好以apache网站上的例子为准，这里仅仅用于说明其基本用法。
调用WebService服务步骤：
a.首先拿到WSdl文档,找到服务地址：http://172.19.0.153:8080/scs-web/webservice/SignService?WSDL
b.使用工具soapui，创建测试项目如图，知道接口方法名和参数
c.创建调用的代码
1.直接AXIS调用远程的webservice
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
public class WebServiceClient {
public static void main(String[] args) {
try {
String endpoint = "http://172.19.0.153:8080/scs-web/webservice/SignService";
// 直接引用远程的wsdl文件
// 以下都是套路
Service service = new Service();
call.setOperationName("signContract");// WSDL里面描述的接口名称
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(endpoint);
call.addParameter("channel",org.apache.axis.encoding.XMLType.XSD_DATE,javax.xml.rpc.ParameterMode.IN);// 接口的参数
call.addParameter("templateId",org.apache.axis.encoding.XMLType.XSD_DATE,javax.xml.rpc.ParameterMode.IN);// 接口的参数
call.addParameter("strJson",org.apache.axis.encoding.XMLType.XSD_DATE,javax.xml.rpc.ParameterMode.IN);// 接口的参数
call.addParameter("isSeal",org.apache.axis.encoding.XMLType.XSD_DATE,javax.xml.rpc.ParameterMode.IN);// 接口的参数
call.addParameter("callBackUrl",org.apache.axis.encoding.XMLType.XSD_DATE,javax.xml.rpc.ParameterMode.IN);// 接口的参数
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);// 设置返回类型
String templateId = "3021";
String channel = "1007";
String strJson = "{\"certApplys\":[{\"useridno\":\"N256613448988875\",\"address\":\"山东省德州临邑县恒源\",\"engName\":\"test\",\"telno\":\"15869611844\",\"email\":\"[email protected]\",\"username\":\"CHENG AI-HSIANG\",\"idTypeCode\":\"Z\"}],\"singnalElement\":{\"a\":\"\",\"b\":\"√\",\"product\":\"利投宝12_B\",\"amount\":\"100,000.00\",\"idType\":\"户照\",\"year\":2016,\"paybankName\":\"兴业银行\",\"backbankCardNo\":\"622908357966352914\",\"idNo\":\"N213447\",\"month\":12,\"lockTime\":12,\"paybankCardNo\":\"622908357966352914\",\"bigAmount\":\"壹拾万元整\",\"name\":\"CHENG AI-HSIANG\",\"customerId\":\"C_20161214000158\",\"contractId\":\"L_20161214291739\",\"backbankName\":\"兴业银行\",\"yearIrr\":\"9.6%\",\"payName\":\"CHENG AIHSIANG\",\"day\":14}}\r\n";
String isSeal = "1";
String callBackUrl = "?";
String result = (String) call.invoke(new Object[] {channel,templateId,isSeal,strJson,callBackUrl});
// 给方法传递参数，并且调用方法
System.out.println("result is :" + result);
} catch (Exception e) {
System.err.println(e.toString());
}
}
}
2.使用Http方式调用远程的webservice
package com.webservice;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
public class WebServiceClient2 {
public static void main(String[] args) {
try {
// 1 指定WebService服务的请求地址：
String wsUrl = "http://172.19.0.153:8080/scs-web/webservice/SignService";
// 2 创建URL：
URL url = new URL(wsUrl);
// 3 建立连接，并将连接强转为Http连接
URLConnection conn = url.openConnection();
HttpURLConnection con = (HttpURLConnection) conn;
// 4，设置请求方式和请求头：
con.setDoInput(true); // 是否有入参
con.setDoOutput(true); // 是否有出参
con.setRequestMethod("POST"); // 设置请求方式
con.setRequestProperty("content-type", "text/xml;charset=UTF-8");
// 5，手动构造请求体
String channel = "1007";
String templateId = "3021";
String isSeal = "1";
String strJson = "{\"certApplys\":[{\"useridno\":\"N256613448988875\",\"address\":\"山东省德州临邑县恒源\",\"engName\":\"test\",\"telno\":\"15869611844\",\"email\":\"[email protected]\",\"username\":\"CHENG AI-HSIANG\",\"idTypeCode\":\"Z\"}],\"singnalElement\":{\"a\":\"\",\"b\":\"√\",\"product\":\"利投宝12_B\",\"amount\":\"100,000.00\",\"idType\":\"户照\",\"year\":2016,\"paybankName\":\"兴业银行\",\"backbankCardNo\":\"622908357966352914\",\"idNo\":\"N213447\",\"month\":12,\"lockTime\":12,\"paybankCardNo\":\"622908357966352914\",\"bigAmount\":\"壹拾万元整\",\"name\":\"CHENG AI-HSIANG\",\"customerId\":\"C_20161214000158\",\"contractId\":\"L_20161214291739\",\"backbankName\":\"兴业银行\",\"yearIrr\":\"9.6%\",\"payName\":\"CHENG AIHSIANG\",\"day\":14}}\r\n";
String callBackUrl = "?";
String requestBody = "
requestBody += " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">";
requestBody += "
requestBody += "
requestBody += "
requestBody += "
requestBody += "
requestBody += "
requestBody += "
requestBody += "
requestBody += "
requestBody += "";
// 6，通过流的方式将请求体发送出去：
OutputStream out = con.getOutputStream();
out.write(requestBody.getBytes());
out.close();
// 7，服务端返回正常：
int code = con.getResponseCode();
if (code == 200) {// 服务端返回正常
InputStream is = con.getInputStream();
byte[] b = new byte[1024];
StringBuffer sb = new StringBuffer();
int len = 0;
while ((len = is.read(b)) != -1) {
String str = new String(b, 0, len, "UTF-8");
sb.append(str);
}
System.out.println(sb.toString());
is.close();
}
con.disconnect();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
}
3.springboot 动态调用
package com.credithc.re.sign.webservice;
import com.credithc.re.sign.service.RedisService;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.namespace.QName;
import java.util.UUID;
@WebService(name = "reSignService")
@Component
public class ReSignService {
@Autowired
private RedisService redisService;
@WebMethod
@WebResult
public String reSign(@WebParam(name = "channel") String channel,
@WebParam(name = "templateId") String templateId,
@WebParam(name = "isSeal") int isSeal,
@WebParam(name = "strJson") String strJson,
@WebParam(name = "callBackUrl") String callBackUrl) {
String uuid = UUID.randomUUID().toString().replaceAll("-", "");
redisService.set(uuid, callBackUrl);
callBackUrl = "http://172.19.0.153:8081/re/sign/callback" + "?id=" + uuid;
// 创建动态客户端
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://172.19.0.153:8080/scs-web/webservice/SignService?wsdl");
Object[] objects = new Object[0];
try {
QName opName = new QName("http://webservice.scs.credithc.com/", "signContract");
objects = client.invoke(opName, channel, templateId, isSeal, strJson, callBackUrl);
System.out.println("返回数据:" + objects[0]);
} catch (java.lang.Exception e) {
e.printStackTrace();
}
return "请求成功";
}
}
package com.credithc.re.sign.config;
import com.credithc.re.sign.webservice.ReSignService;
import org.apache.cxf.Bus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.xml.ws.Endpoint;
@Configuration
public class CxfConfig {
@Autowired
private Bus bus;
@Autowired
private ReSignService reSignService;

public Endpoint endpoint(){
EndpointImpl endpoint = new EndpointImpl(bus,reSignService);
endpoint.publish("/reSignService");
return endpoint;
